装一套ewomail把中途踩到的坑记录下
首先是换源
先备份
mkdir /etc/yun.bak/
mv /etc/yum.repos.d/* /etc/yun.bak/
更换aliyun的源(其他源测试不太理想)
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
或
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
安装epel
yum install -y epel-release
备份epel源
mv /etc/yum.repos.d/epel* /etc/yun.bak/
更换源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
更新缓存
yum clean all
yum makecache
完成以上操作即可
