Preparation:

1. Configure the firewall to open port 80 and port 3306

Vi / etc/sysconfig/iptables

-an input-m state-- state new-m tcp-p tcp-- dport 80-j accept # allows port 80 to pass through the firewall

-an input-m state-- state new-m tcp-p tcp-- dport 3306-j accept # allow port 3306 to pass through the firewall

Note: many netizens add these two rules to the last line of the firewall configuration, causing the firewall to fail to start

The correct thing should be added to the bottom of the default port 22 rule

As follows:

# # after being added, the firewall rules are as follows # #

# firewall configuration written by system-config-firewall

# manual customization of this file is not recommended.

* filter

: input accept [0:0]

: forward accept [0:0]

: output accept [0:0]

-an input-m state-- state established,related-j accept

-an input-p icmp-j accept

-an input-I lo-j accept

-an input-m state-- state new-m tcp-p tcp-- dport 22-j accept

-an input-m state-- state new-m tcp-p tcp-- dport 80-j accept

-an input-m state-- state new-m tcp-p tcp-- dport 3306-j accept

-an input-j reject--reject-with icmp-host-prohibited
