1.修改 vim /etc/yum.repos.d/CentOS-Base.repo 文件 将mirrorlist配置注释掉，并将baseurl修改为阿里云镜像地址 [BaseOS]name=CentOS-$releasever - Base#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infrabaseurl=https
我一开始是没有问题的，只是使用了reflector，然后执行reflector --verbose -l 20 -p http --sort rate --save之后，我就有了20个离我所在路由器最快的连接，事实上这种做法固然没错，但是系统自带的做法是全部都加入进去了，还是系统那种方法高明得多，然后我尝试回到系统默认的那种方式，把在 h

目录问题解决 问题 宿主机网络正常，能ping通。但进入docker容器后，无法ping通，yum任何东西都报如下错误： [root@a4742adb2225 yum.repos.d]# yum install vim Loaded plugins: fastestmirror, ovl Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64

CentOS修改yum源地址 修改镜像源 使用的镜像源为清华大学开源软件镜像站，修改镜像源参考链接为：https://mirror.tuna.tsinghua.edu.cn/help/centos/ 1.1 备份并修改原有文件 cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak 然后编辑 /etc/yum
