centos6 yum源失效

## 近期centos6 官方已经停止维护, 建议升级到centos7 

我们大部分的服务器还是centos6, 因此需要解决,还好官方默认还维护了vault版本. 

地址: https://vault.centos.org/6.10/isos/x86_64/

 一键解决脚本:

curl -o update-centos6yum.sh https://gitee.com/usmile/jenkinslibrary/raw/master/update-centos6yum.sh
chmod +x update-centos6yum.sh
./update-centos6yum.sh
