centos 7配置阿里Yum源
1.先下载阿里yum源
[[email protected] ~]# wget http://mirrors.aliyun.com/repo/Centos-7.repo
2.先把yum源的CentOS-Base.repo备份为CentOS-Base.repo.back
3.随后把下载的阿里yum源拷贝到/etc/yum.repo/起名为CentOS-Base.repo
[[email protected] ~]# mv /root/Centos-7.repo /etc/yum.repos.d/CentOS-Base.repo
[[email protected] ~]# ls /etc/yum.repos.d/
在以上图中已经拷贝成功，接下来执行yum更新源的命令如下：
[[email protected] ~]# yum clean all
[[email protected] ~]# yum makecache
[[email protected] ~]# yum update
以下是update的执行过程！
