Navicat连接mysql报错is not allowed to connect to this MySQL

Navicat连接mysql时报错is not allowed to connect to this MySQL

1. 改表法。

可能是你的帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入MySQL后，更改 “mysql” 数据库里的 “user” 表里的 “host” 项，从"localhost"改称"%"

mysql -u root -p

mysql>use mysql;

mysql>update user set host = '%' where user = 'root';

mysql>select host, user from user;

注：个人觉得不太适用！

【错误内容】：SQL Error (2013): Lost connection to MySQL server at ‘waiting for initial communication packet’, system error: 0

【错产生经过】：链接MySQL时出现.

【解决办法】：打开my.ini，找到[mysqld]项，在其后加入一句：skip-name-resolve，保存，重启mysql服务即可~

2. 授权法。

1）例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

2）如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

3）如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;
