更换yum源为阿里云源

 

1.复制备份:

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

 

 

 

2.下载:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

 

 

 

"-bash: wget: 未找到命令"-解决办法:

 

 

yum -y install wget

 

 

 

3.生成缓存: 

yum makecache

 

 

 

如果失败 先运行:

yum clean all
