10.1. Configuring Proxy Server Access

To enable all yum operations to use a proxy server, specify the proxy server details in /etc/yum.conf. The proxy setting must specify the proxy server as a complete URL, including the TCP port number. If your proxy server requires a username and password, specify these by adding proxy_username and proxy_password settings.

The settings below enable yum to use the proxy server mycache.mydomain.com, connecting to port 3128, with the username yum-user and the password qwerty.

# The proxy server - proxy server:port number
proxy=http://mycache.mydomain.com:3128
# The account details for yum connections
proxy_username=yum-user
proxy_password=qwerty

Example 3. Configuration File Settings for Using A Proxy Server

	Global Settings
	If you define a proxy server in /etc/yum.conf, all users connect to the proxy server with those details when using yum.

10.2. Configuring Proxy Server Access for a Single User

To enable proxy access for a specific user, add the lines in the example box below to the user's shell profile. For the default bash shell, the profile is the file~/.bash_profile. The settings below enable yum to use the proxy server mycache.mydomain.com, connecting to port 3128.

# The Web proxy server used by this account
http_proxy="http://mycache.mydomain.com:3128"
export http_proxy
