1.本地登陆数据库

mico@MacBook-Pro ~ % mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 3845
Server version: 5.7.31 MySQL Community Server (GPL)

2.切换mysql数据库

Database changed

3.执行查询，查看数据库当前有访问权限的信息

mysql> SELECT user, host FROM user;
+---------------+-----------+
| user          | host      |
+---------------+-----------+
| mysql.session | localhost |
| mysql.sys     | localhost |
| root          | localhost |
+---------------+-----------+
3 rows in set (0.00 sec)

mysql>

结果显示root用户只能localhost能访问

4.设置访问权限

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql>

5.刷新访问权限表

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql>

6.重新查看用户表

mysql> SELECT user, host FROM user;
+---------------+-----------+
| user          | host      |
+---------------+-----------+
| root          | %         |
| mysql.session | localhost |
| mysql.sys     | localhost |
| root          | localhost |
+---------------+-----------+
4 rows in set (0.00 sec)
