Linux使用在线YUM源
1.首先保证Linux可以通外网
2.清空/etc/yum.repo下的文件
[root@localhost ~]# cd /etc/yum.repos.d/ [root@localhost ~]# mkdir bak [root@localhost ~]# mv *.repo bak
3.下载repo文件
腾讯云镜像地址
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo
根据系统版本下载对应的文件：
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
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
也可以下载163的镜像源
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo --2022-09-15 22:50:54-- http://mirrors.aliyun.com/repo/Centos-7.repo 正在解析主机 mirrors.aliyun.com (mirrors.aliyun.com)... 111.31.118.239, 111.19.224.238, 111.19.224.241, ... 正在连接 mirrors.aliyun.com (mirrors.aliyun.com)|111.31.118.239|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：2523 (2.5K) [application/octet-stream] 正在保存至: “/etc/yum.repos.d/CentOS-Base.repo” 100%[=================================================>] 2,523 --.-K/s 用时 0s 2022-09-15 22:50:59 (39.2 MB/s) - 已保存 “/etc/yum.repos.d/CentOS-Base.repo” [2523/2523])
4.检查
[root@localhost ~]# yum repolist 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com 源标识 源名称 状态 base/7/x86_64 CentOS-7 - Base - mirrors.aliyun.com 10,072 extras/7/x86_64 CentOS-7 - Extras - mirrors.aliyun.com 516 updates/7/x86_64 CentOS-7 - Updates - mirrors.aliyun.com 4,156 repolist: 14,744
5、如果出现如下报错：

解决如下：
yum只能支持一个例程运行，所以如果有一个例程已经在运行，其他的必须等待该进程退出释放lock。出现这种情况时，可以用以下命令来恢复： 1、rm -f /var/run/yum.pid 2、/sbin/service yum-updatesd restart
