### centos7设置163源脚本

今天还原机器发现yum安装程序时源不好用，手动修改为163源。解决问题之后，顺便整理了脚本，方便日后使用。

```shell

#!/bin/bash

# the script is based "http://mirrors.163.com/.help/centos.html"

# 1. backup

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

# 2. create the repo file

echo '# CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client. You should use this for CentOS updates

# unless you are manually picking other mirrors.

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.

[base]

name=CentOS-$releasever - Base - 163.com

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

[centosplus]

baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/

gpgcheck=1

enabled=0

gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7' > /etc/yum.repos.d/CentOS7-Base-163.repo

# 3. clean and make cache

yum clean all

yum makecache

# ok

```
