使用Yum源安装Nginx-学海无涯

一、设置 yum源

1.安装EPEL EPEL(Extra Packages for Enterprise Linux)是由Fedora Special Interest Group维护的Enterprise Linux（RHEL、CentOS）中经常用到的包。

yum -y install epel-release

2.将yum源设置为清华大学开源镜像站

vi /etc/yum.repos.d/qhdx.repo

#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
