修改CentOS默认yum源为国内yum镜像源
1、首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo
1 [root@localhost ~] # mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2、进入yum源配置文件所在的文件夹
1 [root@localhost ~] # cd /etc/yum.repos.d/3、下载163的yum源配置文件到上面那个文件夹内
CentOS7
1 [root@localhost yum.repos.d] # wget http://mirrors.163.com/.help/CentOS7-Base-163.repoCentOS6
1 [root@localhost yum.repos.d] # wget http://mirrors.163.com/.help/CentOS6-Base-163.repoCentOS5
1 [root@localhost yum.repos.d] # wget http://mirrors.163.com/.help/CentOS5-Base-163.repo
4、运行yum makecache生成缓存
1 [root@localhost yum.repos.d] # yum makecache 提示另外一个程序已经存在使用kill -9 进程ID杀掉线程。再运行一次yum makecache
5、这时候再更新系统就会看到以下mirrors.163.com信息
1 2 3 4 5 6 [root@localhost yum.repos.d] # yum -y update 已加载插件:fastestmirror, refresh-packagekit, security 设置更新进程Loading mirror speeds from cached hostfile * base: mirrors.163.com * extras: mirrors.163.com转载于:https://www.cnblogs.com/powerwu/articles/11467106.html
