Today with the Yum method built a lamp environment, encountered a lot of problems, after Google and the help of predecessors, finally set up the environment, now the complete steps to record down,
1. Change the source, the Sohu is quite useful.
1.1 Backup Centos-base.repo
cd/etc/yum.repos.d/
CP Centos-base.repo Centos-base.repo.bak
1.2 Replace Source
Open the Centos-base.repo with VI and clear the contents, then copy and save the contents below.
# Centos-base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The Mirror system uses the connecting IP address of the client and the
# Update status of each mirror to pick mirrors that is updated to and
# Geographically close to the client. You should the use of this for CentOS updates
# Unless you is manually picking other mirrors.
#
# If The mirrorlist= does not work for you, as a fall back to you can try the
# remarked out Baseurl= line instead.

A. Add. Allow access to port {21:ftp, 80:http}.
Iptables-i rh-firewall-1-input-m state–state new-m tcp-p tcp–dport 21-j ACCEPT
