centos7下快速安装mysql

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

成功安装之后重启mysql服务

初次安装mysql是root账户是没有密码的

设置密码的方法

# mysql -uroot

mysql> set password for ‘root’@‘localhost’ = password(‘mypasswd‘);

mysql> exit

远程授权连接mysql

GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;

FLUSH   PRIVILEGES;
