根据以下指南，我一直尝试在 Centos 服务器上更新 mysql：
http://dev.mysql.com/doc/mysql-repo-excerpt/5.6/en/updating-yum-repo.html
我当前的mysql版本是：
programversion: 5.1.73 - Source distribution
当我运行命令时，我得到以下信息：
[root@****~]# sudo yum update mysql-community-release
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirror.fysik.dtu.dk
* extras: mirror.fysik.dtu.dk
