Mysql初始化root密码和允许远程访问

mysql默认root用户没有密码，输入mysql –u root 进入mysql

1、初始化root密码

进入mysql数据库

mysql>update user set password=PASSWORD('123456')where User='root';

2、允许mysql远程访问,从任何主机登陆

mysql>update user set host = '%' where user ='root';

mysql>GRANT ALL PRIVILEGES ON *.*TO 'root'@'%' IDENTIFIEDBY '123456' WITH GRANT OPTION;
