/etc/init.d/MysqL
本来想安装MysqL5.6或者5.7的，无奈，总是安装出错，所以改为安装5.5
安装步骤
Code:
yum clean all
yum clean Metadata
yum clean dbcache
yum update
2.安装MysqL 5.5
wget http://dev.MysqL.com/get/Downloads/MysqL-5.5/MysqL-server-5.5.48-1.el6.x86_64.rpm wget http://dev.MysqL.com/get/Downloads/MysqL-5.5/MysqL-client-5.5.48-1.el6.x86_64.rpm wget http://dev.MysqL.com/get/Downloads/MysqL-5.5/MysqL-devel-5.5.48-1.el6.x86_64.rpm rpm -ivh MysqL-server-5.5.48-1.el6.x86_64.rpm rpm -ivh MysqL-client-5.5.48-1.el6.x86_64.rpm rpm -ivh MysqL-devel-5.5.48-1.el6.x86_64.rpm3.设置root可以远程登录
