The default port number of MySQL is 3306. MySQL is an open source relational database management system commonly used for data storage and management of websites and applications. When MySQL is installed, it is automatically assigned a default port number of 3306. However, in some cases, you may need to change the MySQL port number.

A common situation is that you have other applications installed on your computer that also use the 3306 port number. To avoid conflicts, you may need to change the MySQL port number to another unoccupied port number.

To change the MySQL port number, you need to edit the MySQL configuration file. The location of the configuration files may vary depending on the operating system and MySQL version. In most cases, the MySQL configuration file is named my.cnf or my.ini.

In the configuration file, you need to find the following line:

# The MySQL server
[mysqld]

Under this section, you can add or modify a line to set a new port number. For example, if you want to change the port number to 8888, you can add the following line:

port=8888

After saving and closing the configuration file, you need to restart the MySQL service for the changes to take effect. You can restart the MySQL service by running the following command in a terminal or command prompt:

sudo service mysql restart

Please note that on some operating systems, you may need to use a different command to restart the MySQL service.

If the restart is successful, you should be able to connect to the MySQL database using the new port number. When connecting to MySQL, you need to specify the new port number in the connection string. For example, if you are using the command line tool, you can run the following command to connect to MySQL:

mysql -h localhost -P 8888 -u username -p

where the -h parameter specifies the host name, the -P parameter specifies the port number, and the -u parameter specifies the user name. The -p parameter specifies the password.

To summarize, the default port number of MySQL is 3306. However, if you need to change the MySQL port number, you can do so by editing the MySQL configuration file. After editing, you need to restart the MySQL service for the changes to take effect, and specify the new port number when connecting to MySQL.
