Once you click thebutton, the MySQL Installation Wizard begins the installation process and makes certain changes to your system which are described in the sections that follow.
Changes to the Registry
The MySQL Installation Wizard creates one Windows registry key
in a typical install situation, located in
HKEY_LOCAL_MACHINE\SOFTWARE\MySQL AB. For
64-bit Windows, the registry location is
AB. A server version specific entry will be created
for each release series of MySQL that you install.
The MySQL Installation Wizard creates a key named after the
release series of the server that is being installed, such as
MySQL Server 5.1. It contains
two string values,
string contains the path to the installation directory. In a
default installation it contains
Files\MySQL\MySQL Server 5.1\. The
Version string contains the release number.
For example, for an installation of MySQL Server
5.1.73, the key contains a value of
These registry keys are used to help external tools identify the
installed location of the MySQL server, preventing a complete
scan of the hard-disk to determine the installation path of the
MySQL server. The registry keys are not required to run the
server, and if you install MySQL using the
noinstall Zip archive, the registry keys are
Changes to the Start Menu
The MySQL Installation Wizard creates a new entry in the Windowsmenu under a common MySQL menu heading named after the release series of MySQL that you have installed. For example, if you install MySQL 5.1, the MySQL Installation Wizard creates a section in the menu.
The following entries are created within the newmenu section:
mysql command-line client and is configured to connect as the: This is a shortcut to the
rootuser. The shortcut prompts for a
rootuser password when you connect.
Changes to the File System
The MySQL Installation Wizard by default installs the MySQL
5.1 server to
Program Files is the default location
for applications in your system, and
5.1 is the release
series of your MySQL server. This is the recommended location
for the MySQL server, replacing the former default location
By default, all MySQL applications are stored in a common
Files is the default location for applications in
your Windows installation. A typical MySQL installation on a
developer machine might look like this:
C:\Program Files\MySQL\MySQL Server 5.1 C:\Program Files\MySQL\MySQL Workbench 5.1 OSS
This approach makes it easier to manage and maintain all MySQL applications installed on a particular system.
In MySQL 5.1.23 and earlier, the default location for the data
files used by MySQL is located within the corresponding MySQL
Server installation directory. For MySQL 5.1.24 and later, the
default location of the data directory is the
AppData directory configured for the user
that installed the MySQL application.
