CentOS6.2 system yum way to install and configure LNMP environment

1. Configure the firewall, open port 80 and port 3306
vi /etc/sysconfig/iptables
-A INPUT -m state –state NEW
-m tcp -p tcp –dport 80 -j ACCEPT (allow port 80 through the firewall)
-A INPUT -m state –state NEW
-m tcp -p tcp –dport 3306 -j ACCEPT (allow port 3306 through the firewall)
Special reminder: 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 below the default port 22 rule
After adding, 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]
-A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 22 -j
ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j
ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j
ACCEPT
-A INPUT -j REJECT –reject-with icmp-host-prohibited
-A FORWARD -j REJECT –reject-with icmp-host-prohibited
COMMIT
#################################################### #######

/etc/init.d/iptables restart #Finally restart the firewall to make the configuration take effect

2. Close SELINUX
vi /etc/selinux/config
#SELINUX=enforcing #Comment out
#SELINUXTYPE=targeted #Comment out

3. Configure CentOS 6.2 third-party yum source (the default standard source of CentOS does not have nginx package)
yum install
wget #Install download tool wget
wget
http://www.atomicorp.com/installers/atomic #Download atomic yum source
sh ./atomic
#install
yum check-update
#Update yum package

vi /etc/nginx/nginx.conf
#edit
user nginx
nginx; #Modify the nginx running account to: nginx user of the nginx group

Two, configure php

vi /etc/php.ini #Edit

date.timezOne= PRC #in line 946
Remove the previous semicolon and change it to date.timezOne= PRC
