Configuring a System to Use a Proxy With a Yum Server

If the organization uses a proxy server as an intermediary for internet access, specify the proxy setting in /etc/dnf/dnf.conf as shown in the following example.

proxy=http://proxysvr.example.com:3128

If the proxy server requires authentication, also specify the proxy_username, and proxy_password settings.

proxy=http://proxysvr.example.com:3128
proxy_username=user
proxy_password=password

Caution:

All dnf users require read access to /etc/dnf/dnf.conf or /etc/sysconfig/rhn/up2date. If these files must be world-readable, don't use a proxy password that's the same as any user's login password, and especially not root's password.
