Linux System Update

After installing CentOS, Update it to the latest system like follows. For yum-plugin-fastestmirror, it is installed for dependency of yum, but if it's not installed, it had better install it. The fastest mirror plugin is designed for use in repository configurations where you have more than 1 mirror in a repo configuration. It makes a connection to each mirror, timing the connection and then sorts the mirrors by fastest to slowest for use by yum. If you are using the default CentOS configuration, and if you are not behind a proxy server, fastestmirror is highly recommended. To be able to use this plugin, you must enable plugins in your /etc/yum.conf file, see Yum Plugins for details. Yum plugins are enabled by default starting with CentOS 5.
