What should I do if navicat reports error 1130 when connecting to mysql?

Deployed a program using Mysql as the database. sqlyog connected to the database of the non-local Mysql server. It was strange that it could not connect and reported a 1130 error.

ERROR 1130: Host 192.168.3.100 is not allowed to connect to this MySQL server

I guess it’s a problem of not being able to give remote connection user permissions. As a result, the problem can be solved by operating the mysql library like this. After logging into mysql locally, change the "host" item in the "user" table in the "mysql" database from "localhost" to '%'.

mysql -u root -p
mysql>use mysql;
mysql>select 'host' from user where user='root';
mysql>update user set host = '%' where user ='root';
mysql>flush privileges;
mysql>select 'host' from user where user='root';

First sentence: Log in as the authorized user root.

Second sentence: Select the mysql library.

The third sentence: Check the host value of the user table in the mysql library (that is, the host/IP name for connection access).

The fourth sentence: Modify the host value (add the host/IP address with the content of wildcard %), of course, you can also directly add the IP address.

Fifth sentence: Refresh MySQL’s system permissions related tables.

Sixth sentence: When checking the user table again, there are modifications.

Remember that the Mysql service needs to be restarted (to ensure that the modification is effective), otherwise the result of the modification may not be reflected.

It should be noted that:

1. The above commands need to be executed under the cmd command.

2. You need to switch to the deployment directory to execute these commands. cd x:\dir

3. MySql commands all end with ";".

4. When executing the first command, you need to manually enter the required password. Do not copy it. It is the password required by the deployment program.
