如果你想连接你的MySQL的时候发生这个错误：
ERROR 1130: Host '192.168.1.3' is not allowed to connect to thismysql server
将网上的资料整理了一下
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>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
如果想关掉
mysql>use mysql;
mysql>update user set host = "localhost" where user = "root" and host= "%";
mysql>flush privileges;
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;
如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.3' IDENTIFIED BY '1235' WITH GRANT OPTION;
撤销权限语法如下
revoke 跟 grant 的语法差不多，只需要把关键字 “to” 换成 “from” 即可：
grant all on *.* to [email protected];
revoke all on *.* from [email protected];
最后一定要 mysql>flush privileges;
