下载mysql的RPM包
官网: https://dev.mysql.com
#下载了CentOS(红帽版本的RPM包)
#下载之后上传至/server/tools下
#下载rz命令直接拖拽
yum install lrzsz -y
安装
解压tar包
#看的官方文档使用的翻译
安装命令
sudo yum install mysql-community-{server,client,common,libs}-*
#虽然使用像yum这样的高级包管理工具来安装包要好得多，但是喜欢直接rpm命令的用户可以用rpm -Uvh命令替换yum install命令;然而，使用rpm -Uvh会使安装过程更容易失败，因为安装过程可能会遇到潜在的依赖关系问题(来自官方文档)
