centos6 官方停止更新源无法使用[epel,elrepo,scl等],自建或用vault做源

使用centos6系列的小伙伴应该发现了，所有centos6里面，都有readme，提示
The whole CentOS 6 is *dead* and *shouldn't* be used anywhere at *all*

如果想用的话，可以使用光盘自建源！
yum install httpd -y
mount -o loop /opt/CentOS-6.10-x86_64-minimal.iso /var/www/html/CentOS-6.10
修改源
cat /etc/yum.repos.d/CentOS-Base.repo
[base]
name=base - $basearch
baseurl=
enabled=1
gpgcheck=1
gpgkey=/RPM-GPG-KEY-CentOS-6



也可以使用vault.centos.org当临时源，国外的，会比较慢
wget 
cat centos-vault.sh
#!/bin/bash
version=`cat /etc/redhat-release |awk '{printf $3}'`
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
cat >/etc/yum.repos.d/CentOS-Base.repo< [centos-vault]
name=centos-vault
failovermethod=priority
baseurl=
gpgcheck=1
gpgkey=RPM-GPG-KEY-CentOS-6
EOF

bash -x centos6-vault.sh

epel的源也无法使用，可以装地址改成

cat /etc/yum.repos.d/epel.repo 
[epel]
name=Extra Packages for Enterprise Linux $releasever - $basearch
baseurl=
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-$releasever
 
[epel-debuginfo]
name=Extra Packages for Enterprise Linux $releasever - $basearch - Debug
baseurl=debug
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-$releasever
gpgcheck=0
 
[epel-source]
