Update System

[1]	Update your system with ‘yum’ command. However, before doing it, Install ‘yum-plugin-fastestmirror’ that looks for fast server and download packages from there automatically when yum command is used.

[root@dlp ~]# yum -y install yum-plugin-fastestmirror Setting up Install Process Resolving Dependencies –> Running transaction check —> Package yum-plugin-fastestmirror.noarch 0:1.1.26-11.el6 set to be updated –> Finished Dependency Resolution Dependencies Resolved =================================================================== Package Arch Version Repository Size =================================================================== Installing:   yum-plugin-fastestmirror   noarch 1.1.26-11.el6 sl 16 k Transaction Summary =================================================================== Install 1 Package(s) Upgrade 0 Package(s) Total download size: 16 k Installed size: 35 k Downloading Packages: yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm | 17 kB 00:00 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction    Installing : yum-plugin-fastestmirror-1.1.26-11.el6.noarch 1/1 Installed:    yum-plugin-fastestmirror.noarch 0:1.1.26-11.el6 Complete! [root@dlp ~]# yum -y update

[2]	The yum-autoupdate script is placed in /etc/cron.daily and it runs everyday by anacron. But it’s risks to update packages automatically without testing if you can not stop your server easily, then turn to false the auto-update setting like follows.

[root@dlp ~]# vi /etc/sysconfig/yum-autoupdate

@ line 7: change to false

ENABLED=”false”
