1、 关闭防火墙
2、 设置权限grant all privileges on *.* to root@"%" identified by 'chai' with grant option
或者grant all on *.* to root@"10.10.1.177" identified by 'chai';
flush privileges;
3、GRANT ALL ON *.* TO 用户名@"%" IDENTIFIED BY "密码" WITH GRANT OPTION;
UPDATE mysql.user SET Password = OLD_PASSWORD('密码') WHERE Host = '%' AND User = '用户名';
FLUSH PRIVILEGES;（这是新建用户）
4、远程登陆数据库的命令行
mysql -u root -p password -h 192.168.1.200 -D database（这样的话password会显示出来）
mysql -u root -p -h 192.168.1.200 （回车要求输入密码，密码不显示）
