mysql允许外网访问以及修改mysql账号密码实操方法

mysql的root账户,我在连接时通常用的是localhost或127.0.0.1,公司的测试服务器上的mysql也是localhost所以我想访问无法访问,测试暂停.

解决方法如下:

1,修改表,登录mysql数据库,切换到mysql数据库,使用sql语句查看"select host,user from user ;"

mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user ='root';mysql>select host, user from user;mysql>flush privileges;

2,授权用户,你想root使用密码从任何主机连接到mysql服务器

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'admin123' WITH GRANT OPTION;flush privileges;

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.104'  IDENTIFIED BY 'admin123' WITH GRANT OPTION;flush privileges;

在MySQL 5.7 password字段已从mysql.user表中删除，新的字段名是“authenticalion_string”.

选择数据库：

use mysql;

update user set authentication_string=password('新密码') where user='root' and Host='localhost';

flush privileges;
