解决CentOS6停止更新支持后yum源失效
https://vault.centos.org/
wget -O /etc/yum.repos.d/CentOS-Base.repo http://file.kangle.odata.cc/repo/Centos-6.repo
wget -O /etc/yum.repos.d/epel.repo http://file.kangle.odata.cc/repo/epel-6.repo
yum makecache
或者直接自己创建 .repo文件
[centos-office]
name=centos-office
failovermethod=priority
baseurl=https://vault.centos.org/6.5/os/x86_64/ # 根据当前系统版本来修改
gpgcheck=1
gpgkey=https://vault.centos.org/6.5/os/x86_64/RPM-GPG-KEY-CentOS-6 # 根据当前系统的版本来修改
sslverify=false # 不验证ssl
yum clean all
yum makecache
yum repolist
