Navicat 链接mysql报错：1045 Access denied for user 'root'@'localhost' (using password: YES)

解决方案：受权远程登陆（123456为数据库root用户密码）

首先使用root用户登陆数据库，而后依次执行如下命令。

use mysql;

grant all privileges on . to ‘root’@’%’ identified by ‘123456’;

flush privileges;

exit;

补充：

select host,user from user;查看

update user set host = ‘%’ where user = ‘root’ and host = ‘localhost’;修改权限

update user set password=password(‘zabbix’) where user = ‘root’; 修改密码
