Posted 2021-01-26 maluscalc

1.修改配置文件
#5.7
sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

#5.6及之前的版本
sudo vim /etc/mysql/my.cnf

#把bind-address参数的值改成你的内/外网IP或0.0.0.0,或者直接注释掉这行。

2.登录数据库
mysql -u root -p
#输入密码

3.转到系统数据库
mysql> use mysql;

4.查询host
mysql> select user,host from user;

5.创建host
#如果没有"%"这个host值，就执行下面这两句：
mysql> update user set host=‘%‘ where user=‘root‘;
mysql> flush privileges;

6.授权用户
#任意主机以用户root和密码mypwd连接到mysql服务器
mysql> grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘mypwd‘ with grant option;

#IP为192.168.1.100的主机以用户myuser和密码mypwd连接到mysql服务器
mysql> grant all privileges on *.* to ‘myuser‘@‘192.168.1.100‘ identified by ‘mypwd‘ with grant option;

7.刷新权限
mysql> flush privileges;
