Install ArangoDB on Fedora 34/33

Relational database management systems dominate many segments of programming. However, it is increasingly common to see real alternatives to this type of database. Of those applications, it seems that MongoDB is one of the most popular but ArangoDB improves and improves every day. In this post, I will tell you about ArangoDB, some of the main features and more. Also, I will show you how to install ArangoDB on Fedora 34/33

A little bit of ArangoDB

ArangoDB is a NoSQL database manager. It is built in C++ and is open source. Its main feature is that it is multi-model. That is, it supports different data models such as (JSON), graphs and key-value.

On the other hand, ArangoDB has two versions. The first one is paid and offers support at different levels. The second is communitarian, ideal for small or educational projects.

If you want to manage a server instance easily, ArangoDB allows it through a nice and intuitive web interface. Besides this, it has connectors for many programming languages, so this should not be a limitation. Of course, it has installers for many Linux distributions.

So let us get to work.

Install ArangoDB on Fedora 34/33

First, open your terminal and update Fedora 34/33

sudo dnf update

Once the system is fully upgraded, it is possible to start the process.

ArangoDB is not present in the main Fedora 34/33 repositories but they provide an external repository where you can install it.

So, navigate to the /etc/yum.repos.d/ folder which is where the repository configuration files are stored.

cd /etc/yum.repos.d/

And inside it, download a file containing the data needed to set up the repository.

sudo curl -OL https://download.arangodb.com/arangodb37/RPM/arangodb.repo
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   195  100   195    0     0   2378      0 --:--:-- --:--:-- --:--:--  2378

And now proceed with the installation by executing:

sudo dnf install arangodb3-3.7.9-1.0
1.- Install ArangoDB on Fedora 33
1.- Install ArangoDB on Fedora 34/33

This will start the installation process.

When it is finished, you will have to start the ArangoDB service

sudo systemctl start arangodb3.service

And make it start with the system:

sudo systemctl enable arangodb3.service
Created symlink /etc/systemd/system/multi-user.target.wants/arangodb3.service → /etc/systemd/system/arangodb3.service.

Verify that all is well on ArangoDB and that it is running

sudo systemctl status arangodb3.service

So, now we can configure it.

Configuring ArangoDB on Fedora

Before using ArangoDB it is useful to make some configurations. First of all, we have to define a root password. To do this, run

sudo arango-secure-installation
Please enter a new password for the ArangoDB root user: 
 Repeat password: 
 2021-05-24T22:13:36Z [9825] INFO [a1c60] {syscall} file-descriptors (nofiles) hard limit is 524288, soft limit is 524288
 2021-05-24T22:13:36Z [9825] INFO [c1b63] {arangosearch} ArangoSearch maintenance: [1..1] commit thread(s), [1..1] consolidation thread(s)
 2021-05-24T22:13:36Z [9825] INFO [95cab] Password changed.
 2021-05-24T22:13:36Z [9825] INFO [7da27] {startup} server will now shut down due to upgrade, database initialization or admin restoration.

After you have the password, you can access the ArangoDB shell.

sudo arangosh
2.- ArangoDB shell
2.- ArangoDB shell

In it, you can do all the operations you want. However, it is also possible to do it from a convenient web interface that we have to enable.

Exit the shell and proceed to edit the /etc/arangodb3/arangod.conf file.

sudo nano /etc/arangodb3/arangod.conf

And there are a series of lines with the endpoint value that you have to configure according to your needs. As I have installed ArangoDB on a server I leave the line like this

endpoint = tcp://0.0.0.0.0:8529

Replace 0.0.0.0.0 with the IP address of your server. Remember that you have several examples to guide you so you can also do it via localhost.

Save your changes and close the editor.

To apply them, restart the ArangoDB service.

sudo systemctl restart arangodb3.service

And open port 8529 in the Firewall.

sudo firewall-cmd --add-port=8529/tcp --permanent
success
sudo firewall-cmd --reload
success

Now open a web browser and go to http://you-server:8529.

3.- ArangoDB login screen
3.- ArangoDB login screen

Login in (username root and the password newly created) and then access the chosen database.

4.- Select the database
4.- Select the database

At last, you will see the ArangoDB dashboard. So, enjoy it.

5.- ArangoDB dashboard

Conclusion

ArangoDB is a very popular database manager and increasingly influential in the world of programming. It is frequently used in IoT technology as well as in mobile phones. As you could see, it is easy to install and thus saves us a lot of work.
