基础源

由于centos7的初始源已经全部死掉，这里提供三种方法

1.替换原有路径

 sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/*.repo
 sed -i s/^#.*baseurl=http/baseurl=http/g /etc/yum.repos.d/*.repo
 sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/*.repo

2.环国内源，无法使用wegt，yum情况下

首先对初始源处理

备份

mkdir  bak
mv /etc/yum.repos.d/CentOS-*  /etc/yum.repos.d/bak

删除

rm -rf /etc/yum.repos.d/CentOS-*

然后拉取

阿里云

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

网易

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

清华

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.tuna.tsinghua.edu.cn/help/centos7/

3.wegt拉取

阿里云

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

网易

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

清理缓存并生成新缓存

yum clean all
yum makecache

openstack源

第二种

# 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.

docker源

通过阿里云拉取

yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
但好像阿里云的也死了

这里推荐其他两个

1Panel和耗子面板

{
    "registry-mirrors": [
        "https://docker.1panel.live",
        "https://hub.rat.dev"
    ]
}

k8s源

[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=0
