尽管源码编译安装看着长串的编译过程执行，有种飘飘然的装B感，但是有的时候的编译不通过和漫长的时间等待着实让人烦。
所以可以试试以下几个源：
1.webtatic
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
2.atomic
wget http://www.atomicorp.com/installers/atomic
chmod +x atomic
./atomic
3.阿里云源
1、备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2、下载新的CENTOS-BASE.REPO 到/ETC/YUM.REPOS.D/
CENTOS 5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CENTOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CENTOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3、之后运行YUM MAKECACHE生成缓存
4.epel
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
su -c 'rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm' #64位
