Prerequisite.

OrientDB is written in Java. For this reason, it is essential to have Java Run Environment installed. If you don’t have it yet, you can download it from the following link. Once you download the file, you only have to install it like any other program for Windows. To verify the installation, open a Command Prompt and type the following command:

java -version

If everything is in order, you will see the Java version installed.

Downloading OrientDB

First, go to the download section of OrientDB. Once there, select the Community Edition for Windows:

The file is compressed in ZIP format. For convenience, unzip it at the root of the Windows installation. In most cases, it is the C:\ drive.

Running OrientDB for the first time.

Then go to the following path: C:\orientdb-3.0.25\bin. Now let’s start the database manager, double-clicking on the file server.bat

This will start the server by opening a CMD console and you will see the following:

The wizard will ask you to assign the password for the root user.

If you want to start the manager using the CMD, you only need to go to the bin folder of the program, and then run server.bat.

cd..
cd..
cd orientdb-3.0.25
cd bin
server.bat

Running the console − You can use the following command to run OrientDB under the console. With this in mind, go to the same previous path and run the following command:

console.bat

Once the server is started, go to the web browser and enter the following in the navigation bar: http://localhost:2480. You have to enter the password created for the root user.

After entering the password correctly, you will see the OrientDB graphical interface.

To shutdown the engine, you need to run the following command from the bin folder:

shutdown.bat -p rootpasword

Remember to replace rootpassword with the password you created.

Conclusion

Finally, we have seen how to install OrientDB in Windows 10. Now you can enjoy the advantages of this NoSQL database manager. All right, that’s it for the moment. Before saying goodbye, I invite you to read our tutorial about chocolatey in Windows 10

The post How to install OrientDB in Windows 10 appeared first on Linux Windows and android Tutorials.

OrientDB is an open source NoSQL database management system written in Java. One of its main features is that it is not only NoSQL based but also very fast. Especially in large projects where performance is indispensable.

Of course, an application of OrientDB quality is expected to have an enterprise version, aimed at companies and that is not free; however, we also have a community version.

For this tutorial we will use the community version. I recommend you to visit the OrientDB website to read all its features.

So, let us start.

Getting OrientDB on Debian 10

1) Install Java on Debian 10

The first step is to install Java. This is because OrientDB is an application created with Java. So we need the Java JRE. You can use the Oracle version or the official repositories version.

Then, open a terminal session and run the following:

:~$ sudo apt install openjdk-11-jre

After finishing the installation, check the installed version:

:~$ java -version
openjdk version "11.0.5" 2019-10-15
OpenJDK Runtime Environment (build 11.0.5+10-post-Debian-1deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.5+10-post-Debian-1deb10u1, mixed mode, sharing)

So, everything is OK. We can continue.

2) Install OrientDB on Debian 10

Now it is OrientDB’s turn. To do this, we will first have to download its binaries from the project’s website. Remember that we are using the community version.

:~$ cd /tmp/
:~$ wget -c https://s3.us-east-2.amazonaws.com/orientdb3/releases/3.0.24/orientdb-3.0.24.tar.gz

After this, unzip the file and move the folder to /opt/orientdb

:~$ tar xvf orientdb-3.0.24.tar.gz
:~$ sudo mv orientdb-3.0.24 /opt/orientdb

For security reasons, it is advisable to create a new user for OrientDB. On top of that, you have to give it ownership of the folder.

:~$ sudo groupadd -r orientdb
:~$ sudo useradd --system -g orientdb orientdb
:~$ sudo chown -R orientdb:orientdb /opt/orientdb

Now we can get the server up and running. To do this, access the /opt/orientdb/bin/ folder and run the server.sh file.

:~$ cd /opt/orientdb/bin/
:~$ sudo ./server.sh

If this is your first time running the server, you will need to define a root key. When you write and confirm it, OrientDB will start.

Now you can open your web browser to access the graphical interface provided by the application. You can access it from the following address http://IP_SERVER:2480/studio/index.html. Remember that port must be open in the Firewall.

So, type your credentials. The user is root and the password what you defined before.

Next, click on the connect button. And you can start to work with OrientDB.

So, that is it.

Conclusion

There are many applications that can store data. These applications known as database management systems are vital for application development. Well, OrientDB focuses a lot on the professional and large scale but we will always be able to use it in our projects because we just learned how to install it.

dnf install -y wget unzip

Step 2: Install and Configure Open JDK

dnf install -y java-1.8.0-openjdk

Set Java’s Home Environment

Run below command to find java path

update-alternatives --config java

In my case it is /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el8_0.x86_64/jre/bin/java

Now Set Java’s Path in Your Environment using below command

vi .bash_profile

Add below line in .bash_profile file

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el8_0.x86_64/jre/bin/java

Save changes and Exit.

Refresh .bash_file to make changes

source .bash_profile

Run below commands to see the Java path you set and the java version.

echo $JAVA_HOME
java -version

Step 3: Install OrientDB

It is recommended to run OrientDB as its own user. Run the following command to create the user orientdb and set its home directory to /opt/orientdb.

adduser orientdb -d /opt/orientdb

Download the OrientDB binary archive by running the following commands

Note: You can get lestest version of OrientDb from OrientDB download page.

OrientDB Enterprise Edition

cd /opt/orientdb/

wget https://orientdb3.s3.us-east-2.amazonaws.com/releases/3.0.23/orientdb-3.0.23.tar.gz -O orientdb.tar.gz

Extract the archive and move files.

tar -xf orientdb.tar.gz
ls
mv orientdb-3.0.23/* .

Remove unnecessary data.

rm -rf orientdb-3.0.23 orientdb.tar.gz

Set appropriate permissions to the OrientDB user.

chown -R orientdb:orientdb /opt/orientdb

OrientDB has been installed on your RHEL / CentOS 8 server.

Start OrientDb Server

Switch to the OrientDB user and run script.

su - orientdb
bin/server.sh

You will be asked to set the password of the OrientDB root user like image below, set the password and press enter.

Now you should see image like below, It OrientDb server is started successfully.

press ctrl + C to stop the execution.

Now switch again to root user by running below command.

exit

Step 4: Configure OrientDB Systemd Service

To start OrientDb service automatically on system boot, create a new systemd service by running the following command

vi /etc/systemd/system/orientdb.service

Now add following lines in that file.

[Unit]
Description=OrientDB service
After=network.target

[Service]
Type=simple
ExecStart=/opt/orientdb/bin/server.sh
User=orientdb
Group=orientdb
Restart=always
RestartSec=9
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=orientdb

[Install]
WantedBy=multi-user.target

Save change to file and exit.

Now you can start and enable OrientDB service on boot.

systemctl start orientdb

systemctl enable orientdb

systemctl status orientdb

Create a soft link for the OrientDB script which starts the console for OrientDB. so we can easily switch to the OrientDB console.

ln -s /opt/orientdb/bin/console.sh /usr/bin/orientdb

Now we can access the OrientDB console by running below command.

orientdb

To exit the OrientDB console using below command

exit

Step 5: Access OrientDB from GUI:

OrientDB Studio is a web based GUI tool to easily administrator OrientDB. It is also installed along with OrientDB package. Once you start OrientDB server, Studio is also started along with it.

We need to allow port 2480 in firewall in order to access OrientDb web interface. Run following commands to add port in firewalld.

firewall-cmd --zone=public --permanent --add-port=2480/tcp
firewall-cmd --reload

Now open the following web address in your browser.

http://your-server-IP:2480

You will see below page on you screen

To create a new database click on NEW DB button and enter name of desired database you want to create.

Now type name of the database and root as the Server User and enter the password of the root user which was set during the installation. Finally Click on CREATE DATABASE to create a new database and you will see the dashboard to manage the database.

OrientDB is an open source NoSQL database management system written in Java. One of its main features is that it is not only NoSQL based but also very fast. Especially in large projects where performance is indispensable. It has an enterprise version and a community version for small projects.

So, let’s start to install OrientDB on Ubuntu 18.04.

1. Install Java

OrientDB requires Java 1.7 to work. You probably already have Java installed on your Ubuntu 18.04. However, I will install the Java Oracle version:

:~$ sudo add-apt-repository ppa:webupd8team/java

Now, install Java using this PPA.

:~$ sudo apt update && sudo apt install oracle-java8-installer

During the installation, you will have to accept the license terms.

After that, it is necessary to set this version as the default.

:~$ sudo apt install oracle-java8-set-default

Then, check the Java version.

:~$ java -version

Now, you can continue.

2. Install OrientDB on Ubuntu 18.04

The installation process is quite simple. First, go the the tmp folder to save the file and then proceed to download.

:~$ cd /tmp/
:~$ wget https://s3.us-east-2.amazonaws.com/orientdb3/releases/3.0.12/orientdb-3.0.12.tar.gz

As I write this post, the latest stable version is 3.0.12.

Now, decompress it.

:~$ tar xvf orientdb-3.0.12.tar.gz

Then, move it to the /opt folder.

:~$ sudo mv orientdb-3.0.12 /opt/orientdb

For security reasons, it is advisable to create a new user for OrientDB. On top of that, you have to give it ownership of the folder.

:~$ sudo groupadd -r orientdb
:~$ sudo useradd --system -g orientdb orientdb
:~$ sudo chown -R orientdb:orientdb /opt/orientdb

And finally, run OrientDB.

:~$ cd /opt/orientdb/bin
:~$ sudo ./server.sh

You have to set the root password.

Then you’ll have OrientDB on Ubuntu 18.04.

3. Create a systemd service for OrientDB

In this step, you already have OrientDB installed. The problem is that to start, stop or restart its execution becomes complicated. Therefore, I am going to create a systemd service for OrientDB.

First, copy the OrientDB service file to the systemd folder.

:~$ sudo cp /opt/orientdb/bin/orientdb.service /etc/systemd/system/

Next, edit the OrientDB service file and add the following:

:~$ sudo nano /etc/systemd/system/orientdb.service

[Unit]
Description=OrientDB Server
After=network.target
After=syslog.target

[Install]
WantedBy=multi-user.target

[Service]
User=orientdb
Group=orientdb
ExecStart=/opt/orientdb/bin/server.sh

In order for the service to be taken into account by the system, the systemd service cache must be reloaded.

:~$ sudo systemctl daemon-reload
:~$ sudo systemctl start orientdb.service

And that’s it.

4. Test the installation

Now the final step is to complete the installation and verify it. Open your web browser and go to http://IP_SERVER:2480/studio/index.html and you should see this.

Log in with root user and the password you defined. You will see this.

And go the schema tab.

Conclusion

There are many advantages to using OrientDB as a database manager. Many large companies do this and trust their applications to this new NoSQL database manager.
