How to view and modify the port number of MySQL under Windows

Take the Win7 system, MySQL version 5.5.57 as an example:

• View the port number of the native MySQL (default is 3306)

1. Open a DOS window

Win+r Open the Run interface input cmd or enter CMD in the Start menu search box and return

• If you want to modify the port number of MySQL, the following actions are required:

1. Locate the My.ini file in the MySQL installation directory

　　　　　　

2. Open through the tool, I use notepad++ ctrl+f search for the MySQL port number we found just now, the default is 3306, we have not changed before, so is 3306. It will be found that there are two "port=3306" in lines 53 and 70, both of which need to be changed. Change to the new port number you want to set (the port number range is 0-65535). (I changed it to 3396)

　　　　3. After the My.ini file is changed and saved, we need to restart the MySQL service. Otherwise, the connection cannot be successful.
