在CentOS 7下更改yum源与更新系统。

[1] 首先备份/etc/yum.repos.d/CentOS-Base.repo

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

[2] 进入yum源配置文件所在文件夹

[[email protected] yum.repos.d]# cd /etc/yum.repos.d/

[3] 下载163的yum源配置文件，放入/etc/yum.repos.d/(操作前请做好相应备份)

[[email protected] yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

[4] 运行yum makecache生成缓存

[[email protected] yum.repos.d]# yum makecache

[5] 更新系统(时间比较久,主要看个人网速)

[[email protected] yum.repos.d]# yum -y update

[6] 安装vim编辑器

[[email protected] ~]# yum -y install vim*
