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
  # If proxy authentication is required

The next step is to declare the variable http_proxy to run
when the yum rpm get executed to avoid the below error:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: nokey, key
ID e8562897

To declare the variable http_proxy run:

# export http_proxy=''

This line can be added to the .bashrc so you will not have to run it each time you log on.
