linux系统怎么打开3306端口

问题描述

精选答案

linux中mysql的3306端口默认是打开的，如果没有打开需要设置防火墙开放3306端口，防火墙开放3306端口的命令为：

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

# Firewall configuration written by system-config-firewall

# Manual customization of this file is not recommended.

:INPUT ACCEPT [0:0]

:FORWARD ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]
