How to prevent remote access from MySQL database bitsCN.com

Solution:

1. change the table method. It may be that your account is not allowed to log on remotely, but only on localhost. At this time, you only need to log on to MySQL on The localhost computer and change the "host" entry in the "user" table in the "MySQL" database, from "localhost" to "%" MySQL-u root-pvmwareMySQL> use MySQL; MySQL> update user set host = '%' where user = 'root'; MySQL> select host, user from user;

2. authorization law. For example, if you want myuser to use mypassword to connect to the MySQL server from any host. Grant all privileges on *. * TO 'myuser' @ '%' identified by 'mypassword' wi th grant option; if you want TO allow myuser TO connect TO the MySQL server from a host with ip address 192.168.1.6, and use mypassword as the password grant all privileges on *. * TO 'myuser' @ '192. 168.1.3 'identified BY 'mypassword' with grant option; I used the first method. I first found that it could not work. I checked it online, run the following statement: MySQL> flush rivileges to make the modification take effect. you can use another method, but I have not tried it myself. you can find it on csdn.net.

Run the following command on the machine where MySQL is installed:

1. d: MySQLbin> MySQL-h localhost-u root // enter the MySQL server.

2. MySQL> grant all privileges on *. * TO 'root' @ '%' with grant option // GRANT data access permissions TO any host

3. MySQL> flush privileges // The modification takes effect.

4. MySQL> EXIT // log out of the MySQL server so that you can log on to any other host as a root user.
