Allow ArangoDB through the firewall

By default, ArangoDB runs on port 8529, so you will need to enable this port through a firewall. You can do this by running the following command:

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

Next, you need to restart the firewall service so that these changes are saved and work. This can be done as follows:

sudo firewall-cmd --reload
