Use commands of CentOS 7 in Linux to update the yum source, centosyum

Follow the instructions to back up the source (use the following command to rename the original source. If there is an error, change it back ):

[Root @ peipei3514 ~] # Mv/etc/yum. repos. d/CentOS-Base.repo/etc/yum. repos. d/CentOS-Base.repo.bar

Go to the source directory and download the source from your own version. I am CentOS 7 and run the following command:

[Root @ peipei3514 ~] # Cd/etc/yum. repos. d/[root @ peipei3514 yum. repos. d] # wget https://mirrors.163.com/.help/CentOS7-Base-163.repo

Run the following command to generate the cache:

[Root @ peipei3514 yum. repos. d] # yum clean all [root @ peipei3514 yum. repos. d] # yum makecache
