How to modify the firewall on a Linux server to allow remote access to the port

1. Problem Description

For security reasons, the newly built server cluster only opens a few designated ports, but after the ports are opened, remote access is still not possible. After finding the problem, it is found that the firewall needs to open the ports, so use the following command to modify the firewall to allow remote access to the ports

2. Solution

Use the command line to execute the statement as follows:

firewall-cmd --zone=public --add-port=<strong>80/tcp</strong> --permanent

firewall-cmd --reload

The above method of modifying the firewall under the Linux server to allow remote access to this port is all the content that the editor shares with you. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM.
