Nginx reverse proxy request YUM

First, install Nginx configuration service (recommended on Nginx server to turn off iptables / firewalld service until after the completion of the experiment according to the actual situation)

[the root @ localhost ~] # yum the install Nginx - Y # install the Nginx 
[the root @ localhost ~] # CD /etc/nginx/conf.d/ 
[the root @ localhost the conf.d] Vim proxy.conf #   # configure proxy rules 
server { 
the listen 80 ; 
server_name mirrors.qiangungun.com;   
LOCATION   / CentOS / {          #yum Base source agent configuration 
   proxy_pass http: // mirrors.aliyun.com/centos/; 
  } 
LOCATION   / EPEL / {           #yum EPEL source agent disposed 
   proxy_pass http : // mirrors.aliyun.com/epel/; 
  } 
} 
# If there are other agents need YUM reference to the above configuration to 
[the root @ localhost the conf.d] # Nginx -t   # syntax checking and restart 
nginx: the Configuration File at The /etc/nginx/nginx.conf syntax IS the ok 
nginx: the Configuration File /etc/nginx/nginx.conf the Test IS successful 
[root @ localhost conf.d] # systemctl restart nginx

Second, the client configuration yum source address access

Configure base source

# 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.

# The above operation will mainly replace the repo file in the specified domain name Nginx proxy server_name in the current lab environment, namely: mirrors.qiangungun.com

Third, the machine is provided parsing hosts

[@ the rsync the root-Client yum.repos.d] # Vim / etc / the hosts
 127.0 . 0.1    localhost localhost.localdomain localhost4 localhost4.localdomain4 
:: . 1          localhost localhost.localdomain localhost6 localhost6.localdomain6
 172.16 . 150.131 mirrors.qiangungun.com   # 172.16 .150.131 Nginx server is configured to address mirrors.qiangungun.com Nginx proxy server_name the domain name and repo files also need to be consistent domain name

Fourth, the test

[@ rsync- the root Client yum.repos.d] # of ping mirrors.qiangungun.com    # test hosts configuration 
[@ the rsync the root -client yum.repos.d] # yum makecache                  # test request yum
