修改yum源，在安装更新rpm包时获得比较理想的速度。国内比较快的有163源、sohu源。这里以163源为例子。

cd /etc/yum.repos.d
mv CentOS-Base.repo CentOS-Base.repo.backup
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
mv CentOS6-Base-163.repo CentOS-Base.repo
yum clean all

[root@hear yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.backup

[root@hear yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
