修改CentOS默认yum源为国内yum镜像源

2018/05/10 linux yum

有时候CentOS默认的yum源不一定是国内镜像,导致yum在线安装及更新速度不是很理想。这时候需要将yum源设置为国内镜像站点。国内主要开源的开源镜像站点应该是网易和阿里云了.

修改CentOS默认yum源为mirrors.163.com

  • 首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo
[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
  • 进入yum源配置文件所在的文件夹
[root@localhost ~]# cd /etc/yum.repos.d/
  • 下载163的yum源配置文件
# 自己根据版本进行下载
# 163
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo  http://mirrors.163.com/.help/CentOS6-Base-163.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo  http://mirrors.163.com/.help/CentOS5-Base-163.repo
# aliyun
wget -O /etc/yum.repos.d/CentOS-Base.repo  http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo  http://mirrors.aliyun.com/repo/Centos-5.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo  http://mirrors.aliyun.com/repo/Centos-6.repo

# 运行yum makecache生成缓存

yum makecache
