centos7 修改yum源为阿里源,某下网络下速度比较快 首先是到yum源设置文件夹里
1.安装base reop源
cd /etc/yum.repos.d

接着备份旧的配置文件
sudo mv CentOS-Base.repo CentOS-Base.repo.bak
- 1
下载阿里源的文件
sudo wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
- 1
2 安装epel repo源:
epel(RHEL 7)
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
- 1
epel(RHEL 6)
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
- 1
epel(RHEL 5)
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-5.repo
- 1
