Cent OS Yum replaces the update source to accelerate

If you have installed centos and the yum update is slow, you can replace the update source with the one provided by Netease: mirrors.163.com.

The procedure is as follows:

CD/etc/yum. Repos. d/
MV CentOS-Base.repo CentOS-Base.repo.bak

VI CentOS-Base.repo
Add the following content:

CentOS-Base.repo download: CentOS-Base.repo # CentOS-Base.repo
#
# This file uses a new release list system developed by Lance Davis for centos.
# The mirror system uses the connecting IP address of the client and
# Update Status of each mirror to pick mirrors that are updated to and
# Geographically close to the client. You shoshould use this for centos updates
# Unless you are manually picking other mirrors.
#
# If the specified list = does not work for you, as a fall back you can try
# Remarked out baseurl = line instead.
