1、登录宝塔面板进行安装

2、设置MySQL连接密码

3、安装好了设置navicat连接

登录MySQL

[root@hecs-394544 ~]# mysql -uroot -p
Enter password: 

切换到MySQL数据

mysql> use mysql
Database changed
mysql> 

查询用户信息

mysql> select host,user from user;
+-----------+------------------+
| host      | user             |
+-----------+------------------+
| %         | root             |
| 127.0.0.1 | test1            |
| localhost | mysql.infoschema |
| localhost | mysql.session    |
| localhost | mysql.sys        |
| localhost | test1            |
+-----------+------------------+
6 rows in set (0.00 sec)

mysql> 

第一行host是我自己添加的，最下面一行是一开始就有的root账户，可以直接把user表的root账户对应的host改为’%'就可以在Navicat上远程登录了，就是SQL的update语句，不用搞得那么复杂

update user set host = '%' where host = 'localhost' and user = 'root';

mysql> update user set host = '%' where host = 'localhost' and user = 'root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0  Changed: 0  Warnings: 0

mysql> select host,user from user;
