Centos换源

资源编号:551200 热度：148

阿里云yum源：
1）备份当前yum源防止出现意外还可以还原回来

```
cd /etc/yum.repos.d/
cp CentOS-Base.repo CentOS-Base-repo.bak
```
2）使用wget下载阿里yum源repo文件
```
wget http://mirrors.aliyun.com/repo/Centos-7.repo
```
3) 清理旧包
```
yum clean all
```
4）把下载下来阿里云repo文件设置成为默认源
```
mv Centos-7.repo CentOS-Base.repo
```
5）生成阿里云yum源缓存并更新yum源
```
yum makecache
yum update
```
方便运行：
```
cd /etc/yum.repos.d/
cp CentOS-Base.repo CentOS-Base-repo.bak
rm /etc/yum.repos.d/CentOS-Base.repo

输入y

wget http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
mv Centos-7.repo CentOS-Base.repo
yum makecache
yum update
```

# 华为源
```
cd /etc/yum.repos.d && rm -rf *

wget -O /etc/yum.repos.d/CentOS-Base.repo https://repo.huaweicloud.com/repository/conf/CentOS-7-reg.repo

yum install -y  https://repo.huaweicloud.com/epel/epel-release-latest-7.noarch.rpm

sed -i "s@http://download.fedoraproject.org/pub@https://repo.huaweicloud.com@g" /etc/yum.repos.d/epel.repo
