This section gives a general overview of starting the MySQL server. The following sections provide more specific information for starting the MySQL server from the command line or as a Windows service.
The information here applies primarily if you installed MySQL
noinstall version, or if you wish
to configure and test MySQL manually rather than with the MySQL Installer.
The examples in these sections assume that MySQL is installed
under the default location of
Files\MySQL\MySQL Server 8.0. Adjust the
path names shown in the examples if you have MySQL installed in
a different location.
Clients have two options. They can use TCP/IP, or they can use a named pipe if the server supports named-pipe connections.
MySQL for Windows also supports shared-memory connections if the
server is started with the
shared_memory system variable
enabled. Clients can connect through shared memory by using the
For information about which server binary to run, see Section 1.4.3, “Selecting a MySQL Server Type”.
Testing is best done from a command prompt in a console window (or “DOS window”). In this way you can have the server display status messages in the window where they are easy to see. If something is wrong with your configuration, these messages make it easier for you to identify and fix any problems.
The database must be initialized before MySQL can be started. For additional information about the initialization process, see Initializing the Data Directory.
To start the server, enter this command:
C:\> "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqld" --console
You should see messages similar to those following as it starts
(the path names and sizes may differ). The
connections messages indicate that the server is ready
to service client connections.
[Server] C:\mysql\bin\mysqld.exe (mysqld 8.0.30) starting as process 21236
[InnoDB] InnoDB initialization has started.
[InnoDB] InnoDB initialization has ended.
[Server] CA certificate ca.pem is self signed.
[Server] Channel mysql_main configured to support TLS.
Encrypted connections are now supported for this channel.
[Server] X Plugin ready for connections. Bind-address: '::' port: 33060
[Server] C:\mysql\bin\mysqld.exe: ready for connections.
Version: '8.0.30' socket: '' port: 3306 MySQL Community Server - GPL.
You can now open a new console window in which to run client programs.
If you omit the

set up a password for it using the instructions in
