CentOS 6.4 Installation Configuration Lamp server (APACHE+PHP5+MYSQL)

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 add these two rules to the last line of the firewall configuration, causing the firewall to fail to start.

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

As shown below:
############################## after adding the firewall rules as follows ##############################
