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 or Red Hat Enterprise Linux:

      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.
