PHP 7.3 comes with a number of new features that make you think about upgrading. Some of them refer to a more flexible heredoc and nowdoc syntax. And several performance improvements in the compiler. Keep in mind that if you are very happy with your current version of PHP, you may not want to update, but on the contrary, if you have a malfunction or want to plug a security hole, I recommend you update.

So, let us install PHP 7.3.

1. Upgrade the system

The first step, update the entire system. I always recommend you to do it for security reasons.

:~$ sudo apt update && sudo apt upgrade

After that, the system is ready to start installing PHP 7.3.

2. Check your current PHP version and the external repository

For the change to be noticeable, first check the version of PHP you have installed. You can do this with the following command:

:~$ php -v

As you can see, I do not have it installed. If as I do not have it installed, you can look for it in the official repositories and see which version you have available for now.

:~$ sudo apt search php

So, you have to add an external PPA to install PHP 7.3. However, first, you have to install these required packages.

:~$ sudo apt install software-properties-common

Then, add the PPA.

:~$ sudo add-apt-repository ppa:ondrej/php

And next, refresh the APT cache.

:~$ sudo apt update

Now, you can install it without any problems.

3. Install PHP 7.3 on Ubuntu 18.04 and Linux Mint

Now yes, first use APT to search for PHP packages and verify that the available version is 7.3.

:~$ sudo apt search php

Now, install PHP 7.3 and some of the most commonly used extensions:

:~$ sudo apt install php7.3 php7.3-cli php7.3-common php7.3-opcache php7.3-curl php7.3-mbstring php7.3-mysql php7.3-zip php7.3-xml

Next, check the version installed:

:~$ php -v

So, that is it.

Conclusion

It is important to update a critical element of a web server such as PHP. This is because development is very active and more and more applications require newer versions of the compiler.

MariaDB: The son surpasses the father

After Oracle buys Sun microsystem, there was a huge concern about MySQL’s future. That’s why MariaDB emerges as a 100% compatible fork maintained by the community and the initial creators of MySQL.

The consequences have been positive, as MariaDB being 100% compatible with MySQL ensures that the Community spirit of MySQL is maintained. In addition, large Linux distributions such as Debian, Ubuntu Server or CentOS include it by default in their official repositories, which makes it available easily and simply.

Debian is stable but it has a cost

As I mentioned earlier, Debian is very stable but its packages are not the latest versions. The great advantage of this is that it makes Debian a very stable distribution but the user misses out on some of the new features corresponding to the packages.

For example, Debian 9 includes MariaDB 10.1 but the last version is 10.3.10.

Before we continue let me warn you that, if you have a server in production and you don’t really need the update, you better not do it. While it’s true that the steps I’m going to take are safe, something can always happen. So, be sure.

Install the latest version of MariaDB

MariaDB 10.3.10 is a minor version of the 10.3 series. Some of its main novelties are: bug fixes on InnoDB, corruption of InnoDB temporary tables is corrected and improvements in program performance. As well as to polish the sentences and to add better syntax to the same ones.

There is no easier way to install the latest stable version of MariaDB than by using the MariaDB repository. In addition to ease, it is quite safe to do it this way and thus you are always guaranteed to be prone to an update of the program.

First, upgrade the system.

:~$ su
:~# apt update && apt upgrade

Doing this ensures that you have the latest security patches installed and have a more stable and reliable system.

Then, install some required packages

:~# install software-properties-common dirmngr

Next, you have to add the GPG key for the MariaDB repository.

:~# apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8

Now, add the repository.

Refresh the APT cache.

Then, install MariaDB packages.

:~# apt install mariadb-server

During installation, you will be asked if you want to define a root password. I chose yes, but you can do it later.

Once the installation is finished, you can access the MariaDB console. There you can run the commands and verify the installed version.

:~# mysql -u root -p

As you can see, the version installed is 10.3.10. In short, it is the last version available of MariaDB.

Conclusion

As you can see, the installation of the latest stable version of MariaDB is really simple and does not require many complications. However, it is important, to have at your disposal the new features

Let’s see why this distribution is so special.

Fedora has the Red Hat power

Fedora is a Linux distribution that uses RPM packages. It is sponsored by Red Hat and provides an updated, innovative and stable system. As expected it is available for free and although its default desktop environment is GNOME, it is also possible to download different Spin with other desktop environments such as KDE, XFCE or Mate.

One issue to which Fedora pays a lot of attention is that of containers, servers, and virtualization. Something that is very much happening these days. Proof of this is that it has three main versions. In the first place is the Workstation version, focused on home computers and everyday work. It is the most used and popular version. Then, it is Server oriented to servers using the best and latest tools of DataCenter. Finally, Atomic is specialized in Docker and Kubernetes technologies.

If a distribution is sponsored by an open source giant like Red Hat, it’s because it’s good and its latest version even better.

Fedora 29 Available

A new version was released recently, and in Matthew Miller’s words is the best yet. This is partly due to the updated package and the fact that this version is the first to be modular.

Fedora Modularity is a technology that has been tested for some time by Fedora that allows you to install several versions of the same package without modifying the basic libraries of the system. As you can notice, it is an innovation within Linux. And this is perhaps the most important novelty of this version.

Another thing to keep in mind is that this new version comes with Linux Kernel 4.18 and GNOME 3.30 as the desktop environment, thus ensuring compatibility with most recent hardware.

How to Upgrade from Fedora 28

It is possible to upgrade from Fedora 28 if you prefer. First, you must update all system packages. Open a terminal and run:

:~$ sudo dnf upgrade --refresh

It is then necessary to install the DNF plugin to update the system version. To do this, type.

:~$ sudo dnf install dnf-plugin-system-upgrade

Once you have finished, you can start the system update.

:~$ sudo dnf system-upgrade download --releasever=29

The above command will download all the new packages needed for the upgrade. In case you have problems with the update, you can add the –allowerasing option to enable the system to make the changes for the update.

Finally, reboot and complete the upgrade:

:~$ sudo dnf system-upgrade reboot

The update will take a while. When you reboot the system. You will have Fedora 29

Conclusion

Fedora is a great Linux distribution and this new version is even more innovative and promises to be the best that has been taken so far.

Linux server-oriented operating systems use not-so-current versions of the basic packages because they are the most tested. This situation has as main advantage that the packages that are in the official repositories are very stable; however, not having the latest versions of the packages means that new features are not always available.

With this in mind, it’s easy to assume that some essential applications can’t be used without updating some key packages like PHP. For example, the latest stable version of Laravel requires PHP 7.1.3 but Debian 9 brings in its repositories version 7.0.

In others words, there are times when it is necessary to update some essential packages. Today it’s PHP’s turn on Debian 9.

Why you need

The process is quite simple, however, you must execute commands as a superuser. To do this, you can use a user with sudo enabled or directly be root.

You also need to be somewhat familiar with the use of the terminal, as we will do everything through the command line interface.

With this in mind, you can get started to install PHP 7.2.

Let’s get to work

Now that you have decided to update PHP, the first thing is to update the system. With that, you will get the versions of the packages but only those related to security. Anyway, it’s a good idea to do it. Run:

:~$ su

Then, enter your password to become root. Now, run:

:~# apt update && apt upgrade

That’s enough.

So, you can check this by executing the following command:

:~# apt-cache show php

As you can see, Debian 9 comes with PHP 7.0 by default.

The next step is to install some necessary packages such as: apt-transport-https lsb-release and ca-certificates.

:~# apt install apt-transport-https lsb-release ca-certificates

To install PHP 7.2 you need an external repository. Run:

:~# wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg

Next:

:~# sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'

Then, proceed to update the repository cache.

:~# apt update

Now, search the repository database for the PHP package and you’ll see that version 7.2 is available.

And proceed to install the PHP 7.2 packages you want. I’ll install these for now.

:~# apt install php7.2 php7.2-common php7.2-cli php7.2-mysql php7.2-xml php7.2-curl

Finally, you can check the installed version. To do this, run.

:~# php -v

Conclusion

In the final analysis, it can be said that having old and tested packages has its advantages but from time to time it is convenient to update them. Especially if other applications make use of them like Laravel with PHP.

Installing PHP 7.2 in Debian 9 is simple and it is recommended to do it to have important security updates especially if the server works a lot with web applications.
