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 GUI
MySQL server starts automatically after using MySQL Installer.
The examples in these sections assume that MySQL is installed
under the default location of
Files\MySQL\MySQL Server 5.6. 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 22.214.171.124, “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.
To start the server, enter this command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld" --console
For a server that includes
you should see the messages similar to those following as it
starts (the path names and sizes may differ):
InnoDB: The first specified datafile c:\ibdata\ibdata1 did not exist: InnoDB: a new database to be created! InnoDB: Setting file c:\ibdata\ibdata1 size to 209715200 InnoDB: Database physically writes the file full: wait... InnoDB: Log file c:\iblogs\ib_logfile0 did not exist: new to be created InnoDB: Setting log file c:\iblogs\ib_logfile0 size to 31457280 InnoDB: Log file c:\iblogs\ib_logfile1 did not exist: new to be created InnoDB: Setting log file c:\iblogs\ib_logfile1 size to 31457280 InnoDB: Log file c:\iblogs\ib_logfile2 did not exist: new to be created InnoDB: Setting log file c:\iblogs\ib_logfile2 size to 31457280 InnoDB: Doublewrite buffer not found: creating new InnoDB: Doublewrite buffer created InnoDB: creating foreign key constraint system tables InnoDB: foreign key constraint system tables created 011024 10:58:25 InnoDB: Started
When the server finishes its startup sequence, you should see something like this, which indicates that the server is ready to service client connections:
mysqld: ready for connections Version: '5.6.51' socket: '' port: 3306
The server continues to write to the console any further diagnostic output it produces. You can open a new console window in which to run client programs.
If you omit the
the server writes diagnostic output to the error log in the data
C:\Program Files\MySQL\MySQL Server
5.6\data by default). The error log is
the file with the
.err extension, and may
be set using the
The accounts that are listed in the MySQL grant tables initially have no passwords. After starting the server, you should set up passwords for them using the instructions in Section 2.10.4, “Securing the Initial MySQL Accounts”.
