CentOS 7的yum源中貌似没有正常安装MySQL时的mysql-sever文件，需要去官网上下载
| # wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm# rpm -ivh mysql-community-release-el7-5.noarch.rpm# yum install mysql-community-server |
成功安装之后重启mysql服务
| # service mysqld restart |
初次安装mysql是root账户是没有密码的
设置密码的方法
| # mysql -u rootmysql> set passWord for ‘root’@‘localhost’ = password('mypasswd');mysql> exit |
