In this post, you will learn how to install ArangoDB on Ubuntu 20.04 So let’s go for it
What is ArangoDB?
ArangoDB is a native multi-model, open-source database with flexible data models for documents, graphs, and key-values. Build high-performance applications using a convenient SQL-like query language or JavaScript extensions. Use ACID transactions if you require them. Scale horizontally and vertically with a few mouse clicks.
On the other hand, to offer graph functionalities, they make use of _from and _to attributes that allow connecting the information. This, in conjunction with edge indexes, allows the processing of graph queries with a great performance.
Install ArangoDB on Ubuntu 20.04
as a great alternative to MongoDB as a NoSQL database manager. This makes us think that the installation of ArangoDB can be complicated but it is not thanks to the repository that the developers give us.
So, install some packages needed to add the repository.
:~$ sudo apt install curl apt-transport-https
Then, download the GPG key from the repository:
:~$ curl -OL https://download.arangodb.com/arangodb36/DEBIAN/Release.key
So, add it to the system with this command:
:~$ sudo apt-key add - < Release.key
Ok
Then add the repository as such:
:~$ echo 'deb https://download.arangodb.com/arangodb36/DEBIAN/ /' | sudo tee /etc/apt/sources.list.d/arangodb.list
The next step is to reroute the APT cache.
:~$ sudo apt update
And now yes, install ArangoDB with the following command:
:~$ sudo apt install arangodb3=3.6.4-1 Reading package lists… Done Building dependency tree Reading state information… Done The following additional packages will be installed: nodejs The following NEW packages will be installed: arangodb3 The following packages will be upgraded: nodejs 1 upgraded, 1 newly installed, 0 to remove and 47 not upgraded. 1 not fully installed or removed. Need to get 82.1 MB/106 MB of archives. After this operation, 327 MB of additional disk space will be used. Do you want to continue? [Y/n]
At the time of writing, the latest stable version is 3.6.4-1. If a new one comes out, just replace this value.
When the installation is happening, you will be asked to set a root password.
Then, you will be asked if you want to update the database files automatically.
On the next screen, you can choose the database engine.
Then you will be asked if you want to back up the database before updating.
Then the whole installation will continue.
You can check the service status with the following command:
:~$ sudo systemctl status arangodb3
sudo systemctl status arangodb3.service

Enabling the ArangoDB web interface
One of the most powerful tools of ArangoDB is undoubtedly its web graphic interface. With it, you can perform many operations quickly and even monitor the operation of the entire program. By default, it only comes authorized for local access, but we can change this if the database is remote.
So, open the ArangoDB configuration file:
:~$ sudo nano /etc/arangodb3/arangod.conf
And change the next line:
endpoint = tcp://127.0.0.1:8529
By:
endpoint = tcp://192.168.250.20:8529
Note: in this case, 192.168.250.20 is the IP address of the computer where ArangoDB is installed.
Save the changes and close the editor.
Finally, restart the ArangoDB service.
:~$ sudo systemctl restart arangodb3
Now open your web browser and go to http://server-ip:8529 and you will see the following:
Enter the root user and the password you created before and you will see the dashboard.
So, enjoy it.
Conclusion
ArangoDB is a program that is having a lot of recent success due to its easy handling and robustness, in addition to its flexibility which makes it ideal for complex tasks.
