what is mysql port
MySQL port refers to the network port number used to establish a connection and communicate with the MySQL server. When an application or client needs to connect to the MySQL server, it needs to specify the host name and port number to connect to. By specifying the correct port number, you can ensure that the connection can be successfully established and communicate normally with the MySQL server.

MySQL port refers to the network port number used to establish a connection and communicate with the MySQL server. In MySQL, port 3306 is used by default.
When an application or client needs to connect to the MySQL server, it needs to specify the host name (or IP address) and port number to connect to. By specifying the correct port number, you can ensure that the connection can be successfully established and communicate normally with the MySQL server.
If you select a non-default port number when installing the MySQL server, you need to use the custom port number when connecting. For example, if the port number of the MySQL server is 8888, you can use the following method to connect to MySQL:
mysql -h hostname -P 8888 -u username -p
where the -h parameter specifies the host name and the -P parameter specifies the port number.
It should be noted that the MySQL server can be configured to listen to different port numbers, and multiple MySQL instances can be run on the same host, each instance using a different port number. Therefore, when connecting to MySQL, make sure to use the correct hostname and port number configured for the corresponding instance.
In summary, the MySQL port refers to the network port number used to communicate with the MySQL server, which is 3306 by default. However, the specific port number may vary depending on the configuration or environment. Please use the correct port number to connect according to the specific situation.
