Configuring ports for operation of the application

Perform the necessary steps for configuring ports if a firewall is enabled on the server.

To configure ports for operation of the application:

1. Open access to the required ports. To do so, run one of the following commands depending on the utilized operating system:
   • CentOS, Red Hat Enterprise Linux, or ALT Server:

     firewall-cmd --add-port=<port>/<protocol> --permanent

   • Ubuntu:

     ufw allow <port>

   • Debian:

     apt-get install iptables-persistent

     iptables -A INPUT -p <protocol> --dport <port> -j ACCEPT

2. Apply the changes. To do so, run one of the following commands depending on the utilized operating system:
   • CentOS or Red Hat Enterprise Linux:

     firewall-cmd --reload

   • Debian:

     netfilter-persistent save

   If you are using Ubuntu OS, the changes are applied automatically.

Ports will be configured for operation of the application.
