2.3.9. Starting the Server for the First Time

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 using the Noinstall version, or if you wish to configure and test MySQL manually rather than with the GUI tools.

The examples in these sections assume that MySQL is installed under the default location of C:\Program Files\MySQL\MySQL Server 5.1. Adjust the pathnames shown in the examples if you have MySQL installed in a different location.

On NT-based systems such as Windows NT, 2000, XP, or 2003, clients have two options. They can use TCP/IP, or they can use a named pipe if the server supports named-pipe connections. For MySQL to work with TCP/IP on Windows NT 4, you must install service pack 3 (or newer).

On Windows 95, 98, or Me, MySQL clients always connect to the server using TCP/IP. (This allows any machine on your network to connect to your MySQL server.) Because of this, you must make sure that TCP/IP support is installed on your machine before starting MySQL. You can find TCP/IP on your Windows CD-ROM.

Note that if you are using an old Windows 95 release (for example, OSR2), it is likely that you have an old Winsock package; MySQL requires Winsock 2. You can get the newest Winsock from Windows 98 has the new Winsock 2 library, so it is unnecessary to update the library.

MySQL for Windows also supports shared-memory connections if started with the --shared-memory option. Clients can connect through shared memory by using the --protocol=memory option.

For information about which server binary to run, see Section 2.3.8, “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 5.1\bin\mysqld" --console

For servers that include InnoDB support, you should see the following messages as the server starts:

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: '5.1.7-beta'  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 --console option, the server writes diagnostic output to the error log in the data directory (C:\Program Files\MySQL\MySQL Server 5.1\data by default). The error log is the file with the .err extension.

Note: 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 2.9, “Post-Installation Setup and Testing”.
