How to set up proxy for yum repository in Linux?

If your RHEL 7 system is configured and running behind a proxy server then you may have to set up proxy for yum repository to access the repository running behind the proxy server on Red Hat Satellite Network.

Set up proxy for yum repository

There are two possible scenarios where you can setup proxy for yum repository.

Configure Proxy for All Repository

Now to set up proxy for yum for all the available repositories, you have to modify /etc/yum.conf. Since this is the main configuration file for all the yum repository, adding proxy here will set up proxy for yum for all the available repositories.

To add a proxy for all the available repository modify your /etc/yum.conf file and add below line as highlighted

[main]
cachedir=/var/cache/yum/$basearch/$releasever
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=3
proxy=http://user:password@proxy.example.com:3128

Configure Proxy for Individual Repository

To add a proxy for individual repository only, you can directly modify the respective repo file inside /etc/yum.repos.d

# cat /etc/yum.repos.d/yum_repo.repo
[repo_yum]
name=yum_repo
baseurl=http://yumrepo.example.com/os
enabled=1
gpgcheck=0
proxy=http://user:password@proxy.example.com:3128

Ignore Proxy for Individual/All Repository

If you specifically want to make sure a repository does not use a proxy then add the below highlighted value in /etc/yum.conf to apply for all the repositories or individual your repo file inside /etc/yum.repos.d

# cat /etc/yum.repos.d/rhel_no_proxy.repo
[repo_yum_no_proxy]
name=yum_repo_no_proxy
baseurl=http://yumrepo.example.com/os
enabled=1
gpgcheck=0
proxy=_none_
