This article mainly introduces the relevant knowledge of "how to configure MySQL port to avoid being occupied". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to configure MySQL port to avoid being occupied" can help you solve the problem.

Problems caused by port occupancy

1.MySQL occupies the port of other applications, making it impossible for other applications to run (for example, Tomcat uses port 80, and Tomcat cannot start after MySQL occupies this port).

The 2.MySQL port is occupied by other applications, so that MySQL cannot be run (for example, if an application occupies port 3306 of MySQL, MySQL cannot be started).

3. Because many ports are used by default, for example, 3306 is the default port for MySQL, if MySQL does not use port 3306, other applications that require database interaction need to be reconfigured (boot to the correct port).

Solution method

The port of MySQL can be set, which can be set in my.ini (my-default.ini) (this file is located in the database folder, the higher version of MySQL does not have such a default configuration file, but creating such a configuration file can also take effect).

Remove the "#" before the port option, then fill in the port number after the equation, and save it. Start the database again and the new port will be used for database interaction.

Matters needing attention

Many applications have a default port, such as port 3306 for MySQL and port 80max for Tomcat. No matter what application it is, it is best to use the default port when configuring it to avoid unnecessary trouble. If the MySQL port is occupied, the correct solution is to clear port 3306 for MySQL use.
