How to create your own online database with Tadabase

Tadabase is a web application. Consequently, you do not need to download any software to use it, as it is accessed directly from the browser. Using it, we will be able to create a database without the need to have any technical knowledge or write a single line of code. We only need to be able to drag and drop the necessary components and then connect them to a database.

This customized database will serve to automate daily business activities. For this purpose, it has an approval process, compliance tracking, customizable dashboard, task management, workflow configuration, among other issues. The platform works by hosting the projects created on our personal subdomain created. There, we can upload at the same time a data file that we want to use to process the personal information we entered at the time, such as a program like Microsoft Excel.

To test this online application, simply create a free account. Then upload a data file in CSV format, information that will be treated as a warehouse. Something that we must emphasize is that at the beginning it may seem somewhat complex. However, as you get more practice, you will be able to drive with ease. Let’s take a look at some features.

New data table

A data table is a collection of data, similar to a spreadsheet. In fact, you just need to give a name for the table and the fields you want to record, such as Customers or Orders. Once the database has been created and configured, we can use the information it contains to create pages in the form of tables, forms, graphs, etc.

The same platform offers a page that serves as a template. Consequently, we can start from scratch with a design or edit the existing one. When we are going to create a new page, we will have to assign a name and choose its design. We will also have to configure other parameters.

Task automation

From this section we can create scheduled tasks to trigger customized or on-demand automated workflows. For example, we can send automated emails and schedule them. It is also possible to generate a script that we can use to display components of our application. For example, it can be used to view records on the company’s website, such as its inventory, public route time or its asset listings.

Subsequently, to the page that we are going to create, we will do it with the CSV data that we have loaded. Therefore, we will be able to add elements such as buttons, graphs, images, frames, etc. To do so, it will only be necessary to drag and drop the objects. Once finished, the page is saved, and we can share it thanks to the subdomain assigned at the beginning.

Insert plugins

This web application also has support for various plugins from its Pipes section. Indeed, it has a good number of categories such as Utilities, API, Forms, Marketing, Surveys, Project Management, Time Management, among others. In addition, there is compatibility with such popular tools as Slack, Twitter, Trello, Google, Calendar, among many others. In addition, several of them are configurable. To install it, you only need to click on the desired one and then click on the Install button.

Tadabase: is it really recommended?

I know what you are wondering. Does Tadabase really work to create our own database? Well, it is certainly an option to consider for those who need to create an online database but do not have programming skills. In addition, it provides the user with all kinds of tools to carry it out. Therefore, it is a web solution for our database low cost, high security and rich in features. Specially designed for people who know nothing about coding.

Tadabase Plans and Pricing

Tadabase provides a 14-day free trial period. The only thing we will need to do is to register for which we can use our email and password. We can also access from our GitHub, Facebook, Twitter, and Google accounts. Once the trial period is over, it is necessary to purchase one of the following plans:

• Plus: access to 10 applications, 100,000 records and 20 GB storage for $125 per month with annual billing.
• Pro: access to 25 applications, 250,000 records and up to 50 GB of storage for $208 per month with annual billing.
• Premium: up to 50 applications with 500,000 records and up to 100 GB storage for $400 per month with annual billing.
• Bronze: allows up to 125 applications with 12,500,000 records and 200 GB storage, for $750 per month and annual billing.

We have already mentioned that it is a web application. Consequently, to use it, we only need a browser and an internet connection. So, it is not necessary to install any additional software.

Alternatives to Tadabase

Tadabase behaves very well. However, there are other alternatives to create databases:

Quickbase

It allows users to create applications so that we can manage almost any process starting with a template. In addition, allows building it from scratch in a simple way through the database. It even allows extracting data and information such as ERP and CRM, as well as create dynamic dashboards that are updated in real time. We can access a free 30-day version from their website.

SQLite is a small, reliable, and very fast database engine. It is one of the most efficient database engines in the world. In part, thanks to that made in C Language which makes it very efficient in managing the resources of the system.

In like manner, the development of SQLite is so important that many major companies participate in it. This is done through the SQLite Consortium. In addition, all the code is available to be downloaded, viewed, and reused for being open source.

So, let us start.

Install SQLite on Debian 11

SQLite has outstanding Linux support. Proof of this is that it is present in most of the existing distributions. In this sense, Debian 11 also has this privilege.

So, open a terminal or from a terminal interface, update the whole system.

sudo apt update
sudo apt upgrade

Then, you can search inside the repositories for all the packages that are related to SQLite.

sudo apt search sqlite

The next step is to install SQLite by executing the following command

sudo apt install sqlite3

Once you have completed the installation, you can verify the version that has been installed.

sqlite3 --version
3.34.1 2021-01-20 14:10:07 10e20c0b43500cfb9bbc0eaa061c57514f715d87238f4d835880cd846b9ealt1

This way, the installation has been successful,

Using SQLite to test the installation

Now, let’s use a little SQLite to check that everything went well. First, let’s create a new database

sqlite3 example.db

Since example.db does not exist then it will be created. The second time you want to access it, it will not be created.

Now I will create a new table with some fields. The important thing is to test the operation.

sqlite> CREATE TABLE Student
               (
               Id VARCHAR(25) NOT NULL,
               Name VARCHAR(25) NOT NULL,
               Last_Name VARCHAR(25) NOT NULL,
               Age INTEGER(2) NOT NULL,
               CONSTRAINT pk_Student PRIMARY KEY (Id)
               );

Also, check that the table has been created, showing the database tables.

sqlite> .tables
Student

Now add some data to the table.

sqlite> INSERT INTO Student (Id, Name, Last_Name, Age) VALUES ('Xy01','Jon','Snow',18);

And finally, display them.

sqlite> SELECT * FROM Student;

Now, you can use SQLite to make projects. Type .exit to close SQLite shell. Enjoy it!

Conclusion

SQLite is a great database application and if we learn to use it, it would be a great help for our projects. Installing it is very easy and gives us a lot of work possibilities. In this post, you learned how to install it and give some steps to use it.

MariaDB is a well-known archi Database Relationships Management System that is a MySQL fork. This is due to the purchase of Sun Mycrosystem by Oracle. It is perfectly compatible with MySQL and is available in most Linux distributions.

In Rocky Linux 8 / AlmaLinux 8 / CentOS 8 the version of MariaDB that is available in the official repositories is 10.3 but recently has seen the release of version 10.6 with some interesting new features.

So, if you want to take advantage of having a recent version of this database manager, then welcome.

Install MariaDB 10.6 on Rocky Linux 8 / AlmaLinux 8 / CentOS 8

MariaDB’s support with Linux is quite good and proof of this is that it provides us with a dedicated repository for Rocky Linux 8 / AlmaLinux 8 / CentOS 8 to facilitate installation.

So, access your server or start a terminal session and update the system. In this post, I worked as the root user. Also, you can use sudo if your user has permission to do so.

dnf update

And make sure you have installed the nano text editor

dnf install nano

Then we have to create a new repository entry in the DNF configuration which is /etc/yum.repos.d/

So, create a file called mariadb.repo

nano /etc/yum.repos.d/mariadb.repo

And add the following information:

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.6/rhel8-amd64
module_hotfixes=1
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1 

Then save the changes and close the editor.

Now install MariaDB 10.6

dnf install mariadb-server

During the installation, you will have to accept the GPG key from the repository and the installation will continue.

Then you have to start the MariaDB service:

systemctl start mariadb

and proceed to the configuration with the mariadb_secure_installation script

mariadb_secure_installation
Switch to unix_socket authentication [Y/n] y
Remove anonymous users? [Y/n]
Disallow root login remotely? [Y/n]
Remove test database and access to it? [Y/n]
Reload privilege tables now? [Y/n]

After the installation is complete, check the installed version:

mysql --version
mysql  Ver 15.1 Distrib 10.6.3-MariaDB, for Linux (x86_64) using readline 5.1

So, you can enjoy MariaDB.

Conclusion

MariaDB 10.6 is a good improvement over previous versions. But it is not always available in the official repositories of other Linux distributions. Today you have learned how to install it in Rocky Linux 8 / AlmaLinux 8 / CentOS 8.

In terms of proprietary database managers perhaps Oracle Database, IBM DB2, and Microsoft SQL Server are the most used and common options by many companies. They have the great advantage of having large companies behind them that provide a high level of support to their operations.

Also, there are other quite competent open-source options such as MySQL, PostgreSQL, or Percona. However, many companies still trust their data to proprietary options and the fact that we can install them in Ubuntu speaks well of our system. So let’s go for it.

Install Microsoft SQL Server on Ubuntu 20.04 / Debian 10

As you can imagine, SQL Server is not available in the official Ubuntu repositories but it is available through the repository offered by Microsoft.

So, open a terminal or connect via SSH and update the system:

sudo apt update
sudo apt upgrade
sudo apt install software-properties-common 

Then import the GPG key from the Microsoft repository.

sudo wget -qO- https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

After that, add the SQL Server repository as such.

sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/ubuntu/18.04/mssql-server-2019.list)"

Next, refresh APT.

sudo apt update

And now you can install Microsoft SQL Server by executing the following command:

sudo apt install mssql-server
Reading package lists... Done
Building dependency tree

Need to get 235 MB of archives.
After this operation, 1,102 MB of additional disk space will be used.
Do you want to continue? [Y/n]

This way it will be installed.

Preparing Microsoft SQL Server for the first use

During the installation process, you will notice that at the end, you will get an output screen similar to this one:

Setting up python-is-python2 (2.7.17-4) ...
Setting up libc++1:amd64 (1:10.0-50~exp1) ...
Setting up mssql-server (15.0.4102.2-4) ...

+--------------------------------------------------------------+
Please run 'sudo /opt/mssql/bin/mssql-conf setup'
to complete the setup of Microsoft SQL Server
+--------------------------------------------------------------+

Processing triggers for man-db (2.9.1-1) ...
Processing triggers for mime-support (3.64ubuntu1) ...
Processing triggers for libc-bin (2.31-0ubuntu9.2) ...

In it, we are told that it is necessary to configure the application before using it and it even tells us the command to start the configuration.

sudo /opt/mssql/bin/mssql-conf setup
usermod: no changes
Choose an edition of SQL Server:
  1) Evaluation (free, no production use rights, 180-day limit)
  2) Developer (free, no production use rights)
  3) Express (free)
  4) Web (PAID)
  5) Standard (PAID)
  6) Enterprise (PAID) - CPU Core utilization restricted to 20 physical/40 hyperthreaded
  7) Enterprise Core (PAID) - CPU Core utilization up to Operating System Maximum
  8) I bought a license through a retail sales channel and have a product key to enter.

Details about editions can be found at
https://go.microsoft.com/fwlink/?LinkId=2109348&clcid=0x409

Use of PAID editions of this software requires separate licensing through a
Microsoft Volume Licensing program.
By choosing a PAID edition, you are verifying that you have the appropriate
number of licenses in place to install and run this software.

Enter your edition(1-8):

The main configuration we have to do is to enter the license. In this case, I have used the Developer which is free and we can use it for the post.

Also, you have to accept the license terms and create the administrator key which has to be complex.

With this SQL Server will be installed but we are missing one more detail.

For now, you can check the status of the service to see if everything is in order:

sudo systemctl status mssql-server
● mssql-server.service - Microsoft SQL Server Database Engine
     Loaded: loaded (/lib/systemd/system/mssql-server.service; enabled; vendor preset: enabled)

             └─3218 /opt/mssql/bin/sqlservr

Install SQL Server tools and UnixODBC

Although the Server is ready, we have to install other components like the Tools and fundamentally the UnixODBC connector without this we will not be able to make a connection with the server.

So, add the GPG key and the repository:

curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
OK
wget https://packages.microsoft.com/config/ubuntu/19.10/prod.list
sudo mv prod.list /etc/apt/sources.list.d/mssql-release.list

After this, refresh APT to apply the change:

sudo apt update

And finally, install both the UnixODBC connector and the Mssql-tools

sudo ACCEPT_EULA=Y apt install mssql-tools unixodbc-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following additional packages will be installed:

Need to get 9,845 kB of archives.
After this operation, 53.9 MB of additional disk space will be used.
Do you want to continue? [Y/n]

After the installation, add the directory to the bash_profile so that the command is available from the whole system.

echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile

In the end, you can connect to the shell by running:

sqlcmd -S 127.0.0.1 -U SA

Note: if you cannot execute the command, log out and try again.

Now you will be able to use Microsoft SQL Server on Ubuntu 20.04 / Debian 10

Conclusion

Microsoft SQL Server is pretty good at what it does and that is why many companies have it as their database manager. Having it available on Ubuntu 20.04 / Debian 10 is not a difficult task and brings us even closer to the integration between Microsoft and Linux products.

PostgreSQL 13 is the latest stable version of what is perhaps the most advanced open-source relational database manager. So many sysadmin need to have it on the different servers.

If you want to know all the news or at least the most important ones, you can read this post

PostgreSQL 13 is available

Well, PostgreSQL 13 comes with many important improvements and it’s a good time to install it. That’s what this post is about.

So let’s go for it.

Install PostgreSQL 13 on Debian

PostgreSQL is included in the official Debian repositories, but not in version 13 but in version 11.

The installation of PostgreSQL 13 is possible thanks to the repository it has for APT package managers that is used by Debian, Ubuntu, Linux Mint and derivatives.

So let’s start.

First, open a terminal session or connect to your server using SSH. Then, install some necessary packages:

:~$ sudo apt install gnupg gnupg2

At the end, the PostgreSQL 13 repository should be added to the list of Debian software sources. To do this, create the following file:

:~$ sudo nano /etc/apt/sources.list.d/pgdg.list

And in it he adds the following:

deb http://apt.postgresql.org/pub/repos/apt/ buster-pgdg main

Then save the changes by pressing CTRL + O and close the file by pressing CTRL + X.

For the repository to be accepted by the system, you need to add the gpg key to it. To do this, use the following command:

:~$ wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
OK

Once the process has been completed, simply update the APT cache.

:~$ sudo apt update

You can now view all the packages related to PostgreSQL 13 by typing

:~$ sudo apt install postgresql-13

But don’t press enter, just press the TAB key and you’ll see the following:

As you can see in the image, we have PostgreSQL 13 available. So to install it run the following command:

:~$ sudo apt install postgresql-13
Reading package lists... Done
Building dependency tree 
Reading state information... Done
The following additional packages will be installed:
libgdbm-compat4 libjson-perl libllvm7 libperl5.28 libpq5 libxslt1.1 perl pgdg-keyring postgresql-client-13 postgresql-client-common postgresql-common ssl-cert
Suggested packages:
perl-doc libterm-readline-gnu-perl | libterm-readline-perl-perl make libb-debug-perl liblocale-codes-perl postgresql-doc-13 openssl-blacklist
Recommended packages:
libjson-xs-perl sysstat
The following NEW packages will be installed:
libgdbm-compat4 libjson-perl libllvm7 libperl5.28 libpq5 libxslt1.1 perl pgdg-keyring postgresql-13 postgresql-client-13 postgresql-client-common postgresql-common
ssl-cert
0 upgraded, 13 newly installed, 0 to remove and 10 not upgraded.
Need to get 34.5 MB of archives.
After this operation, 145 MB of additional disk space will be used.
Do you want to continue? [Y/n]

Now we’ll see if everything went well.

Testing the installation

By default, Debian when installing PostgreSQL starts and enables the service. Therefore, it is ready to be tested. However, if you want to stop the service, you can use this command:

:~$ sudo systemctl stop postgresql

On the other hand, the best way to know if PostgreSQL is ready for work is to execute some command from the console. So we’ll access it first:

:~$ sudo -i -u postgres

Remember that the PostgreSQL console is accessed through the postgres user.

And finally, we access with this command:

:~# psql

Once inside, we can, for example, display all the databases in the system:

:~# \l

And so we can work without problems with PostgreSQL.

Conclusion

PostgreSQL 13 is a powerful database manager that is used in many projects worldwide. This makes many people want to have the latest stable versions to take even more advantage of the tool.

MongoDB allows your teams to easily organize, use and enrich data – in real time, anywhere. MongoDB is a NoSQL and document-oriented database manager. In short, instead of saving the data in the record as the SQL database, it saves them in documents with BSON format which is a binary representation of JSON.

In the world of unrelated SQL database MongoDB is perhaps the most popular, however, it can be used by very different applications that require a semi-structured data collection. On the other hand, its use in transactional systems is not recommended as MongoDB does not support transactions.

That’s why I’m going to teach you how to install MongoDB on the latest stable versions of Fedora, Fedora 34 / 33.

Install MongoDB on Fedora 33

It is possible to install MongoDB on Fedora 34 / 33 through the RPM packages that can be downloaded and installed from the project’s website.

However, the most efficient method is to install from the official MongoDB repository which helps to integrate the application with the system.

So, for ease of use, install the nano text editor.

sudo dnf install nano

And edit a text file to add the MongoDB repository by adding the following content

sudo nano /etc/yum.repos.d/mongodb.repo

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/8/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

Save the changes and close the text editor.

Now you can install MongoDB on Fedora 34 / 33 by running

sudo dnf install mongodb-org

After installation, a new service is created for Fedora 34 / 33.

So, refresh the list of system daemons

sudo systemctl daemon-reload

Now start it up:

sudo systemctl start mongod

And then check the status of the service

sudo systemctl status mongod
● mongod.service - MongoDB Database Server
      Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)

     "version": "4.4.4",
     "gitVersion": "8db30a63db1a9d84bdcad0c83369623f708e0397",

         "target_arch": "x86_64"
     }
 }

So, enjoy it.

Conclusion

So, MongoDB is a solution that is increasingly being taken into account by many developers worldwide. Its installation in Fedora 34 / 33 is relatively simple.

DbGate is a modern database management client that works with both SQL drivers such as MariaDB, MySQL; and with NoSQL such as MongoDB.

We are talking about a Free and open-source application that has been released under the MIT license. This makes that you can use it in many projects of diverse nature.

Another aspect to take into account with DbGate is that it is cross-platform. This means that we can use it on Windows, macOS, and of course Linux. Quite useful to improve possible migrations between operating systems. If you come from Windows, you can also use this application.

With DbGate you can easily:

• Connect to multiple databases, directly or through SSH tunnel. Important in terms of security.
• Browse or edit data in your tables or views, filter by column value. This using a data editor.
• Edit SQL queries with auto-complete suggestions or use query designer.
• Export and import from/to CSV, JSON, or Excel.
• Connect to MongoDB, browse or filter JSON document data.

In addition to this, you can further extend the functionality of the program by adding plugins.

Install DbGate on Linux

In the Linux chaos, we have several options depending on the system you are using. In the case of Debian, Ubuntu and derivatives there is a DEB package that can be downloaded from Github or using the terminal.

wget -c https://github.com/dbgate/dbgate/releases/download/v4.2.0/dbgate-latest.deb

And then install it, using APT.

sudo apt install ./dbgate-latest.deb

Then you can run it from the main menu.

There are also other formats like APPImage that you can run from any other Linux distribution or use the binaries.

Conclusion

Having professional tools for database management is a serious matter that requires some preliminary research. At the moment, DbGate has all the basic features to make it a solid alternative to others on the market. Being OpenSource and including Linux support, it generates more exceptions and is an option to take into account.

Enjoy it!

The need to do this depends on each sysadmin. In the case of a developer, it may be required to have more control over the data or to copy it to a portable device.

Also, if we have different volumes on the system it may be a good idea to change the location to another partition so that if there is a failure on the main hard disk it doesn’t affect our data.

So it really depends on your needs but it is always good to know this process.

Change the MariaDB / MySQL data directory

First, proceed to install MariaDB if you don’t have it.

sudo apt install mariadb-server

In CentOS, Fedora, RHEL

sudo dnf install mariadb

In any case, we need MariaDB / MySQL properly installed.

Next, create the folder that will be the new location of the data:

mkdir -p [path]

Replace [path] with the location of your folder. Then, make mysql the owner of it

sudo chown -R mysql:mysql [path]

Now check which is the location where the application data is located.

sudo mysql -u root -p -e "SELECT @@datadir;"

Output:

Enter password: 
+-----------------+
| @@datadir       |
+-----------------+
| /var/lib/mysql/ |
+-----------------+

Once this is done, you need to stop the MariaDB / MySQL service.

sudo systemctl stop mariadb

Now copy all the data that has been made in MariaDB to the new location including permissions and attributes.

sudo cp -R -p /var/lib/mysql/* [path]

Then you need to modify the MariaBD configuration file which on DEbian, Ubuntu and derivatives is /etc/mysql/mariadb.conf.d/50-server.cnf and on CentOS is /etc/my.cnf.

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

And under the [mysqld] section add

[mysqld]
datadir=[path]
socket=[path]/mysql.sock

And under [client]

port=3306
socket=[path]/mysql.sock

Remember to replace [path] with the path to the folder you have created and that will be the new location of the data.

Now start the service

sudo systemctl start mariadb

And you can check again the location of the data to see if everything went well.

sudo mysql -u root -p -e "SELECT @@datadir;"

Output:

Enter password: 
+-----------------------+
| @@datadir             |
+-----------------------+
| /home/angelo/newdata/ |
+-----------------------+

So, enjoy it.

One more thing…

You can choose any folder to be the new location for the data. However, if this folder is in /root or /home there will be a permissions problem that you have to fix.

To do this you have to edit the MariaDB service file

sudo nano /usr/lib/systemd/system/mariadb.service

And inside the file locate the ProtectHome value and change it from :

ProtectHome=true

To

ProtectHome=false

Save the changes and close the file.

To apply the changes you have to refresh the daemon directory.

sudo systemctl daemon-reload

And now repeat the process.

Conclusion

Changing the MariaDB data directory can be quite useful in database administration. Especially when it is sensitive data that we need to have always at hand.

MariaDB documentation

According to the project’s website, “SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine.” Also, it is open-source.

The great feature of SQLite is that it is easily implemented in mobile applications. That is to say since it is not managed as a service, it makes it possible for our applications to move along with the database.

On the other hand, SQLite boasts that it is the most used database manager in the world, and if we take into account the great number of mobile applications, we can believe it.

Install the latest version of SQLite

The first thing we must do is prepare the operating system with the necessary packages for the compilation and construction of packages from the source code.

So, open a terminal and run to install them

sudo apt-get install build-essential tar wget

Once the installation is finished, we have to download the SQLite source code.

At the time of writing this post, the latest stable version is 3.33.0. To download it using wget, run the following command:

wget -c https://www.sqlite.org/2020/sqlite-autoconf-3330000.tar.gz

The command will vary by version, to make sure which one it is, you can visit the SQLite website.

We already have the SQLite source code downloaded. Create a folder for SQLite and access it.

mkdir sqlite3 && cd sqlite3

And then, unzip the file in this folder:

tar xvfz ../sqlite-autoconf-3330000.tar.gz

Access the generated folder:

cd sqlite-autoconf-3330000/

And configure the code to start the compilation:

./configure

Compile SQLite with the make command:

make 

And finally, install it:

sudo make install

In the end, you can check the results by running the command sqlite3. For example, to show the installed version:

sqlite3 --version
3.33.0 2020-08-14 13:23:32 fca8dc8b578f215a969cd899336378966156154710873e68b3d9ac5881b0ff3f

So, that way you can install the latest version of SQLite on Ubuntu 20.04 Enjoy it.

Previously we explained that the storage engine is a fundamental component of database managers. With them, we define many ways about how our data is stored. Also, it is good to say that there are many and all are good but each in certain circumstances.

So, if your WordPress site needs a change of storage engine, in this post we will tell you how to do it easily and safely.

Previous steps

In this post, it is assumed that WordPress is already installed and running. If not, there are our posts that will help you install it without problems.

How to install WordPress on Ubuntu 20.04?
How to install WordPress on Debian 10?

To facilitate the whole process, we have chosen to use also PHPMyAdmin as a tool. This will help us with some steps.

How to install PHPMyAdmin on Debian 10?

With this done, we can start.

Changing MySQL / MariaDB storage engine for a WordPress site

Open your web browser and open PHPMyAdmin. You will see the following screen:

As you can see in the image, I have a database called wordpress which is where the site data is.

The process is quite safe but it is always convenient to make a backup of the database.

So, select the wordpress database and go to the Export tab and make a backup of the whole database by pressing the Go button.

Perhaps the fastest method is to use SQL code. So, click on the SQL tab.

What we have to do is modify each table that makes up the WordPress database. As I am using a recent installation of WordPress you may have many more tables.

So, in my case these are the lines I have to run:

ALTER TABLE wp_commentmeta ENGINE=InnoDB;
ALTER TABLE wp_comments ENGINE=InnoDB;
ALTER TABLE wp_links ENGINE=InnoDB;
ALTER TABLE wp_options ENGINE=InnoDB;
ALTER TABLE wp_postmeta ENGINE=InnoDB;
ALTER TABLE wp_posts ENGINE=InnoDB;
ALTER TABLE wp_termmeta ENGINE=InnoDB;
ALTER TABLE wp_terms ENGINE=InnoDB;
ALTER TABLE wp_term_relationships ENGINE=InnoDB;
ALTER TABLE wp_term_taxonomy ENGINE=InnoDB;
ALTER TABLE wp_usermeta ENGINE=InnoDB;
ALTER TABLE wp_users ENGINE=InnoDB;

Remember that if you want to change to MyISAM you only have to modify the commands, for example:

ALTER TABLE wp_commentmeta ENGINE=MyISAM;

Then click on the Go button.

Then you will see a screen where you can see that each modification has been done correctly.

And you will continue to enjoy your website without any problems.

So, enjoy it.

Conclusion

Changing the storage engine of all the tables in a WordPress site can be helpful for your site. The process is quite simple, but it is always advisable to do it after backing up our database.
