A native Windows distribution of MySQL has been available since version 3.21 and represents a sizable percentage of the daily downloads of MySQL. This section describes the process for installing MySQL on Windows.
If you are upgrading MySQL from an existing installation older than MySQL 4.1.5, you must first perform the procedure described in Section 2.10.6, “Upgrading MySQL on Windows”.
To run MySQL on Windows, you need the following:
A Windows operating system such as XP, Vista, and Server 2003. Newer versions of Windows than these are not supported. Windows 95/98/ME/2000 and versions of Windows older than these are no longer supported. For supported platform information, see http://www.mysql.com/support/supportedplatforms/database.html.
A Windows operating system permits you to run the MySQL server as a service. See Section 126.96.36.199, “Starting MySQL as a Windows Service”.
Generally, you should install MySQL on Windows using an account
that has administrator rights. Otherwise, you may encounter
problems with certain operations such as editing the
PATH environment variable or accessing the
Service Control Manager.
TCP/IP protocol support.
Enough space on the hard drive to unpack, install, and create the databases in accordance with your requirements (generally a minimum of 200 megabytes is recommended.)
For a list of limitations on the use of MySQL on the Windows platform, see Section D.7.6, “Windows Platform Limitations”.
There may also be other requirements, depending on how you plan to use MySQL:
To connect to the MySQL server using ODBC, you must have a Connector/ODBC driver. See Chapter 20, Connectors and APIs.
If you need tables with a size larger than 4GB, install MySQL on
an NTFS or newer file system. Do not forget to use
AVG_ROW_LENGTH when you create tables. See
Section 13.1.10, “CREATE TABLE Syntax”.
MySQL for Windows is available in several distribution formats:
Binary distributions are available that contain a setup program that installs everything you need so that you can start the server immediately. Another binary distribution format contains an archive that you simply unpack in the installation location and then configure yourself. For details, see Section 2.10.1, “Choosing An Installation Package”.
The source distribution format contains all the code and support files for building the executables using the Visual Studio compiler system.
Generally speaking, you should use a binary distribution that includes an installer. It is simpler to use than the others, and you need no additional tools to get MySQL up and running. The installer for the Windows version of MySQL, combined with a GUI Configuration Wizard, automatically installs MySQL, creates an option file, starts the server, and secures the default user accounts.
Virus-scanning software such as Norton/Symantec Anti-Virus on directories containing MySQL data and temporary tables can cause issues, both in terms of the performance of MySQL and the virus-scanning software misidentifying the contents of the files as containing spam. This is due to the fingerprinting mechanism used by the virus-scanning software, and the way in which MySQL rapidly updates different files, which may be identified as a potential security risk.
After installing MySQL Server, it is recommended that you disable
virus scanning on the main directory
datadir) used to store your
MySQL table data. There is usually a system built into the virus
scanning software to enable specific directories to be ignored.
In addition, by default, MySQL creates temporary files in the
standard Windows temporary directory. To prevent the temporary
files also being scanned, configure a separate temporary directory
for MySQL temporary files and add this directory to the virus
scanning exclusion list. To do this, add a configuration option
tmpdir parameter to your
my.ini configuration file. For more
information, see Section 188.8.131.52, “Creating an Option File”.
The following section describes how to install MySQL on Windows using a binary distribution. To use an installation package that does not include an installer, follow the procedure described in Section 2.10.4, “Installing MySQL on Microsoft Windows Using a noinstall Zip Archive”. To install using a source distribution, see Section 2.10.8, “Installing MySQL from Source on Windows”.
