None of our client VM’s have direct access to internet so we’ll setup a proxy server that the machines can use to acess internet and do external yum installs from time to time.

• Install squid proxy

  yum -y install squid

• Edit /etc/squid/squid.conf . Add your local network that will use the proxy server. The rest of the default options can stay.

  acl localnet src 192.168.88.0/24

• Start squid

  systemctl start squid

• Enable on boot

  systemctl enable squid

• Add this line to your client’s /etc/yum.conf to enable proxied yum install

  `proxy=http://proxy.gracie.net:3128`
