Default MySQL Port Numbers [ You Should Know ]

Are you looking to learn more about MySQL port numbers, including default MySQL port numbers? This blog post will help you with different port numbers of MySQL.

MySQL is a database management system used over a network to add, access, and process data stored in a database. To connect directly or access your MySQL database or to connect a different application to the database, you need information such as the MySQL port number.

Default MySQL port numbers

For your database, the default MySQL port number is 3306, although most applications will set the port number by default, in other cases, it may change. The port number may also be changed for security purposes. This may change because another application is already using the database port number.

The MySQL protocol uses the default port to connect to utilities such as ‘mysqldump’ and the MySQL client.

Are there vulnerabilities when using ports?

When the default port 3306 is open, the MySQL server is vulnerable to attack. So, the user needs to explore other secure options if they want to access the database remotely.

Instead of opening MySQL port 3306, consider alternatives like an SSH tunnel Another option is to restrict the IP addresses that can access the port to prevent connections by suspicious hosts. Although the default port is 3306, this does not mean that MySQL will always use it. Running a short SQL query can help you identify the port on which your MySQL is running.

The port used by the MySQL feature

There is a wide range of ports used by MySQL properties. They include:

Client-server connection port

Port 3306 is the default port used by utilities such as MySQL Client, mysqldump, and MySQL Connector. It is also the default port for the classic MySQL protocol. The protocol is supported by clients such as MySQL Router, MySQL Shell, and MySQL Connector.

MySQL administrative connection port

MySQL Server allows the configuration of TCP/IP ports for administrative connections. This port extends the administrative connection options allowed on the network interface for normal connections.

MySQL shell port

The MySQL shell is an advanced code & client editor. The MySQL shell supports both the classic MySQL and X protocols.

Other ports include the high availability port, key management port, MySQL Workbench port, Memcached protocol port, and external authentication port.

How to find out which port your MySQL is running on?

You may find that anywhere from one to ten ports are used in your MySQL ecosystem. The port used is largely determined by the components used, what is enabled, how your apps connect, and general characteristics of the MySQL environment.

The ideal way to use ports is to make them wide enough to accommodate different components while at the same time blocking untrusted hosts.

There are several ways to establish the port your MySQL server is listening on. If you are connected to your MySQL server, you can run the “show variable where variable name (‘hostname,’ ‘port’) query.

If you use Windows, you can check the MySQL port number in the configuration file.

Here are the steps.

• Go to “my.ini file”.
• Open the “Services” window and search for properties then you will find the location of the my.ini file.
• Open the .ini file.

After finding the file location, find the MySQL port listening on Windows.

How to change the port number of MySQL? [Step-by-step guide]

MySQL port awareness is important because it helps to understand when it will be used.

Port 3306/TCP

The default port 3306 connects the MySQL client to the MySQL server. Communication on this port is encrypted by default. Communication direction on this port is from client to server and is required unless X protocol is used.

Port 33060/TCP

Communication from this port is from MySQL client to server, and communication is also encrypted. The port is also required for communication unless the default 3306 is used.

Port is 33062/TCP (default)

Communication on the port is from client to server and is encrypted. Note that this MySQL port is configured specifically to support administrative connections. MySQL’s administrative interface makes it possible to perform operations such as user administration, server configuration, log viewing, and export and import.

Port 33061/TCP

33060/TCP and 3306/TCP are classified as shell ports alongside 33061/TCP. InnoDB cluster requires port 33061/TCP to run Port communication is also encrypted. The main role of the port is to test a server during InnoDB cluster configuration.

Port 22/TCP

MySQL Workbench unifies administration, database design, maintenance, creation, and SQL development. The Visual Database Design Tool integrates all of the aforementioned components into a single development environment for database systems.

Port 22/TCP is a workbench port where communication is directed from MySQL Workbench to the server. Communication rides on connections through an SSH tunnel.

Conclusion

It is important to be aware of the different MySQL ports. You need to understand what they are, what ports they use when using them, and the level of security in terms of encryption and access restrictions. The best information we provide is MySQL port, default MySQL port, and different port numbers of MySQL. If you want to know the difference between windows vs windows server.
