linux下配置Mysql授权某个用户远程访问，不受ip限制

1. 登录mysql

mysql -u root -p

 2. 用户管理

use mysql;

3. 查看用户

select host,user from user;

 

 

 4. 新建并授权用户

# (*.*是允许远程访问的IP的值, 用户名建议不要使用root, '%'表示所有IP)
grant all privileges on *.* to '用户名'@'%' identified by '密码' with grant option;

flush privileges;

5. 更新用户信息

# 根据user和host条件 更新host为 %
update user  set Host = '%' where Host = 'localhost' & user = 'xxxin_999';

flush privileges;

6. 删除用户

delete from user where user="xxxin_999" and Host="localhost";

flush privileges;
