Modify the yum source of centos

The yum installation method is very convenient in a network environment. It is very meaningful to select a fast Yum source (1) automatically select the fastest source because the speed of some mirror in yum is very slow, if Yum selects this mirror, yum will be very slow at this time. For this, you can download the fastestmirror plug-in, which will automatically select the fastest mirror: yum install Yum-fastestmirror-yfastestmirror configuration file: (do not change it normally)/etc/Yum/pluginconf. d/fastestmirror. conf: The speed test record file of your yum image:/var/Cache/Yum/timedhosts.txt (2) has been unable to cope with the speed of the centos update source.
