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=http://192.168.2.4/CentOS-6.10
enabled=1
gpgcheck=1
gpgkey=http://192.168.2.4/CentOS-6.10/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 https://raw.githubusercontent.com/akin520/AutoSetup/master/centos6-vault.sh
cat centos-vault.sh
#!/bin/bash
version=`cat /etc/redhat-release |awk '{printf $3}'`
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
cat >/etc/yum.repos.d/CentOS-Base.repo<[centos-vault]
name=centos-vault
failovermethod=priority
baseurl=https://vault.centos.org/$version/os/x86_64/
gpgcheck=1
gpgkey=https://vault.centos.org/$version/os/x86_64/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
