This article mainly introduces how to open the remote port of CentOS7, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article.

Generally speaking, when we use the server, we will open some ports so that the remote server can be accessed locally.

The systemctl status firewalld command is used to view the current status of the firewall

Firewall-cmd-- zone=public-- add-port=XX/tcp-- permanent permanently opens a port number, and XX represents the port number. Here we demonstrate opening port 18306.

After opening the port number, you need to restart the firewall, otherwise it will not take effect.

Check whether the port number has been opened successfully

The output of yes proves that opening is successful, while no fails.
