解决Navicat 出错:1130-host . is not allowed to connect to this MySql server,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。
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;
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;
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;
