目的：解决内网服务器无法访问yum服务，而搭建内网yum代理服务器
一、安装配置Nginx服务(Nginx服务器上建议先关闭iptables/firewalld服务，待实验完成后再根据实际情况配置)
yum install nginx -y
cd /etc/nginx/conf.d/
vim proxy.conf
server{
listen 80;
server_name mirrors.cxsw.com;
location /centos/ { #yum base源代理配置
proxy_pass http://mirrors.aliyun.com/centos/ ;
}
location /epel/ { #yum epel源代理设置
proxy_pass http://mirrors.aliyun.com/epel/ ;
}
}
nginx -t #检查语法并重启
二、客户端配置yum源访问地址
/etc/yum.repos.d/CentOS-Base.repo #配置base 源
# CentOS-Base.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.
#
#

三、设置本机hosts解析
vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.233.3 mirrors.cxsw.com
四、测试
[root@localhost yum.repos.d]# ping mirrors.cxsw.com
