Step:-1. Upgrade the system

First, you need to update the system completely. With this, you will have a faster and more agile system to perform the tasks. In addition, you will have installed the latest security patches intended to solve problems in the packages.

# yum update

As I said before, updating the system is necessary to improve the stability and security of the system.

Step:-2. Install ArangoDB on CentOS 7

The most efficient way to install ArangoDB on a CentOS 7 system is to do it through YUM. For this, it is vital to add the official repository of ArangoDB. So, let us do it.

# cd /etc/yum.repos.d/
# curl -OL https://download.arangodb.com/arangodb34/RPM/arangodb.repo

Step:-3. Then, you can start with the installation of ArangoDB using YUM.

# yum install arangodb3

After that, you have to enable and start the ArangoDB service.

# systemctl enable arangodb3
# systemctl start arangodb3

It is a good idea to check the service status to find some issues.

# systemctl status arangodb3

So, ArangoDB is correctly installed and it is running properly too. Finally, you can access to the ArangoDB console

# arangosh

@Now, you can start to use it.

Step:-4. Using the web interface

ArangoDB has a quite friendly and useful web interface, with it you will be able to make multiple configurations and operations in a very friendly way. To enable it is necessary to edit some configuration files.

# vi /etc/arangodb3/arangod.conf

And add the following:

endpoint = tcp://SERVER_IP:8529

In my case, it would be something like this.

After that, do the same with the other configuration file.

# vi /etc/arangodb3/arangosh.conf

Step:-5. Then, restart the ArangoDB service.

# systemctl restart arangodb3

Next, set the firewall rules to allow the use of the port 8529 by ArangoDB.

# firewall-cmd --add-port=8529/tcp --permanent
# firewall-cmd --reload

After that, open the web browser and go to http://SERVER_IP:8529 and you will see this:

Step:-6. ArangoDB web interface Now, we have to change the root password. Just type:

# systemctl stop arangodb3
# ARANGODB_DEFAULT_ROOT_PASSWORD=your_password arango-secure-installation

Step:-7. Change the root password, You can also run the command to change the root password:

# arangodb_secure_installation

Go back to the web browser and log in.

Step:-08. Log in

# Next, select the database.

Step:- 09. Select the database

# And you will see the main screen.

Step:-10. ArangoDB interface
