Redhat / Fedora Using yum with a proxy
Most companies these days restrict their internet access by forcing the usage of web proxy. If your company is forcing a proxy policy & you are running Redhat/CentOs/Fedora you will have to update your yum.conf to be able to update your desktop or server using yum over a proxy connection. Luckily setting up yum to run over a proxy is an easy task. below is the few steps you need to follow to establish just that.
Edit the file /etc/yum.conf
and add the following lines:
# The proxy server - server: port
proxy=http://proxy.mydomain.com:3128
# If proxy authentication is required
proxy_username=yum_user
proxy_password=yun_user_password
The next step is to declare the variable http_proxy to run
when the yum rpm get executed to avoid the below error:
