The editor will share with you how to open the designated port under Linux. I hope you will get something after reading this article. Let's discuss it together.

In order to install the default open ports in the Linux system, there are only 22, 80 and other ports. If you want to open other ports, you can only open them manually.

Take MySQL as an example to enable remote access to port 3306. Other ports are similar.

1. Modify the iptables file:

Vi / etc/sysconfig/iptables adds the following line of configuration:

-An INPUT-p tcp-m tcp-- dport 3306-j ACCEPT Note: if the configuration of this port already exists, change DROP to ACCEPT:

-An INPUT-p tcp-m tcp-- dport 3306-j DROP = > ACCEPT2, restart iptables:

Service iptables restart3, view open ports:

/ sbin/iptables-L-n
