[[email protected] mysql]# mysql -u root -p
Enter password:

2：查看user表,修改连接级别
mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select host,user from user;
+-----------+------------------+
| host | user |
+-----------+------------------+
| localhost | root |
| localhost | mysql.infoschema |
| localhost | mysql.session |
| localhost | mysql.sys |
+-----------+------------------+
4 rows in set (0.00 sec)
可以看到,root用户的host值为localhost,这代表只能本地连接,将localhost修改为%
update user set host=‘%‘ where user=‘root‘;
3：可能你觉得到这一步就完事了,但是使用navicat连接测试时,会提示无法解析主机名相关的错误,这是mysql8的一些安全策略的问题,具体请左转google,解决办法如下
ALTER USER ‘root‘@‘%‘ IDENTIFIED WITH mysql_native_password BY ‘yourpassword‘;FLUSH PRIVILEGES;
4：完毕
