Configure yum with proxy server on RHEL/OL/Fedora

When using yum to maintain packages on hosts running Red Hat Enterprise Linux (RHEL), Oracle Linux (OL) or Fedora, you may have to configure proxy option if the host is running behind firewall.

In order to do that, add following lines to yum configuration file /etc/yum.conf

proxy=http://<proxy server>:<port>
proxy_username=<user name>
proxy_password=<password>

Here, 

  <proxy server> is the host name or IP address of proxy server
  <user name> user name if proxy server requires
  <password>  password if proxy server requires

File /etc/yum.conf  example
gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
best=True
skip_if_unavailable=False
proxy=http://proxy.dbaplus.ca:8080
proxy_username=user01
proxy_password=user01pwd
