标题: 【Linux】yum安装
一、删除原来的yum源

1、检查yum源：

  1. rpm -qa | grep yum
复制代码
2、删除原来的yum源

  1. rpm -qa|grep yum|xargs rpm -e --nodeps
复制代码
3、防止系统自带的插件subscription-manager订阅管理器进行注册

  1. vi /etc/yum/pluginconf.d/subscription-manager.conf
  2. #enabled=1
复制代码
二、拷贝这三个安装包

如果没有可以从这个地址下载：https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/
yum-3.4.3-168.el7.centos.noarch.rpm
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
三、安装三个包

1、使用以下下令一次性安装3个包

  1. rpm -ivh yum-*
复制代码
2、检查是否安装成功

  1. rpm -qa |grep yum
复制代码
四、设置repo文件

1、在linux中进入etc文件，备份yum.repos.d文件

  1. cd /etc
  2. mv yum.repos.d yum.repos.d.bak
  3. mkdir yum.repos.d
复制代码
2、下载repo文件

  1. wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
复制代码
或者
  1. wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
复制代码
3、修改下载好的repo文件

下载好的repo文件应该在etc/yum.repos.d目录下，里面应该也只有一个文件，直接vim 文件名
  1. vim /etc/yum.repos.d/CentOS-Base.repo
复制代码
把repo文件里全部 $releasever全部更换成版本号7
操作如下：
按下i键，然后按:
输入下令：
  1.                 %s/$releasever/7/g
复制代码
更换完毕后，按Esc，然后 :wq 生存退出vim模式
2）-3）也可以手工放入
  1. # CentOS-Base.repo
  2. #
  3. # The mirror system uses the connecting IP address of the client and the
  4. # update status of each mirror to pick mirrors that are updated to and
  5. # geographically close to the client.  You should use this for CentOS updates
  6. # unless you are manually picking other mirrors.
  7. #
  8. # If the mirrorlist= does not work for you, as a fall back you can try the
  9. # remarked out baseurl= line instead.
