CentOS 6.4 Installation Configuration Lamp server (apache+php5+mysql) _linux

Prepare the article:

1, configure the firewall, open 80 ports, 3306 ports
Vi/etc/sysconfig/iptables
-A input-m state--state new-m tcp-p TCP--dport 80-j ACCEPT #允许80端口通过防火墙
-A input-m state--state new-m tcp-p TCP--dport 3306-j ACCEPT #允许3306端口通过防火墙

Note: Many netizens have added these two rules to the last line of the firewall configuration, causing the firewall to start failing,

The correct one should be added to the default 22 port under this rule

As shown below:
