This howto provide a solution if you want to update your linux server when this server is behind a proxy server.

CONFIGURE YUM.CONF

yum.conf before the modification.

# cat /etc/yum.conf

[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1

# Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h

installonly_limit = 5

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

Now we have to modify yum.conf and add the good option.

Add this options in you yum to pass through the proxy server.

http_proxy=http://proxy_ip:port

Add those options, if you need to use authentification on the proxy server.

proxy_username=proxy_user_name
proxy_password=proxy_user_password

EXAMPLE

yum.conf with authentification

[main]
http_proxy=http://proxy.generationip.com:3128
proxy_username=proxyuser
 proxy_password=proxypassword
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1

#  Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h

installonly_limit  = 5

# PUT YOUR REPOS HERE OR IN separate files named file.repo
#  in /etc/yum.repos.d
