How to deal with MySQL connection error 1317?

MySQL is a very popular relational database management system that is widely used in various web applications and servers. However, when using MySQL, you sometimes encounter various errors, one of which is "Connection Error 1317". This article will introduce how to handle this error so that users can use MySQL more smoothly.

MySQL connection error 1317 refers to an error that occurs when trying to create a new user or change the password of an existing user. When this error occurs, the system will prompt "Query execution was interrupted" or "Query execution was interrupted, max_statement_time exceeded", causing the connection to fail to be successfully established. This error usually occurs when executing the following commands: CREATE USER, ALTER USER, or SET PASSWORD.

To solve connection error 1317, you can try the following methods:

1. Modify the configuration file: Open the MySQL configuration file my.cnf (or my.ini) and find [mysqld ] section and add the following lines:

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

Save the file and restart the MySQL service. This will disable strict mode, fixing an issue that caused connection error 1317 in some cases.

2. Restart MySQL service: Sometimes, connection error 1317 is just a temporary problem and can be solved by restarting the MySQL service. Enter the following command in the terminal or command prompt:

sudo service mysql restart

or

sudo systemctl restart mysql

This will restart Start the MySQL service, clear the temporary problem and restore normal connections.

3. Using the command line interface: Sometimes, graphical user interfaces such as phpMyAdmin fail to execute specific MySQL commands correctly, resulting in connection error 1317. In this case, you can try using a command line interface such as Terminal or CMD to execute the command. Open the command line interface, enter the following command and press Enter:

mysql -u root -p

Then enter the MySQL root password. This will open the MySQL command line interface, where user and password related commands can be executed without encountering connection error 1317.

4. Use root user: If none of the above methods work, you can try to use root user to create a new user or change the password. Enter the following command on the command line interface and press Enter:

mysql -u root -p

Then enter the MySQL root password. Next, execute the following command to create a new user or change the password:

CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'password';
(Replace 'new_user' and 'new_user' with your new username and password 'password')

ALTER USER 'user'@'localhost' IDENTIFIED BY 'new_password';
(Replace 'user' and 'new_password' with the username and new password to be modified)

This will use root user privileges to perform relevant operations, thus solving connection error 1317.

To sum up, MySQL connection error 1317 is a common problem, but it can be easily solved with appropriate methods and techniques. Choose the appropriate method based on the situation, and back up your database as needed to prevent data loss. At the same time, MySQL and related software are regularly updated to ensure system security and stable operation.
