How to use the command to open the port in linux? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1. Turn on the firewall

Systemctl start firewalld

2. Open designated ports

Firewall-cmd-zone=public-add-port=1935/tcp-permanent

Meaning of the command:

-- zone # scope

-- add-port=1935/tcp # add port in the format: Port / communication protocol

-- permanent # is in effect forever. Without this parameter, it will expire after restart.

3. Restart the firewall

Firewall-cmd-reload

4. Check the port number

Netstat-ntlp / / View all current tcp ports netstat-ntulp | grep 1935 / / check the usage of all 1935 ports.
