[Switch] centos: Change Yum source to domestic

Http://blog.csdn.net/pkueecser/article/details/8836973

Important: storage path

　　

cd /etc/yum.repos.d

Back up CentOS-Base.repo first

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

Method 1: directly download the source file

Centos USTC mirror is a good image. You can update and use this image.

# Yum-y install wget

# Cd/etc/yum. Repos. d

# Mv CentOS-Base.repo CentOS-Base.repo.save

# Wget http://centos.ustc.edu.cn/CentOS-Base.repo

NOTE: If it is the first time to install a new system, you need to first install the wget download software, otherwise there is no way to download the CentOS-Base.repo file.

Method 2: manually create source files

Change the yum image site to the Chinese site address. We recommend that you use http://centos.ustc.edu.cn/centos /. (China University of Science and Technology)

# Cd/etc/yum. Repos. d/

# Mv CentOS-Base.repo CentOS-Base.repo.bak

# Vi CentOS-Base.repo

Save and run

Yum makecache
