On Windows, you need not create the data directory and the grant tables. MySQL Windows distributions include the grant tables with a set of preinitialized accounts in the mysql database under the data directory. It is unnecessary to run the mysql_install_db script that is used on Unix. Regarding passwords, if you installed MySQL using the Windows Installation Wizard, you may have already assigned passwords to the accounts. (See Section 2.3.3.1, “Using the MySQL Installation Wizard”.) Otherwise, use the password-assignment procedure given in Section 2.12.2, “Securing the Initial MySQL Accounts”.

Before setting up passwords, you might want to try running some client programs to make sure that you can connect to the server and that it is operating properly. Make sure that the server is running (see Section 2.3.5.4, “Starting the Server for the First Time”), and then issue the following commands to verify that you can retrieve information from the server. You may need to specify directory different from C:\mysql\bin on the command line. If you used the Windows Installation Wizard, the default directory is C:\Program Files\MySQL\MySQL Server 5.5, and the mysql and mysqlshow client programs are in C:\Program Files\MySQL\MySQL Server 5.5\bin. See Section 2.3.3.1, “Using the MySQL Installation Wizard”, for more information.

Use mysqlshow to see what databases exist:

C:\> C:\mysql\bin\mysqlshow
+--------------------+
|     Databases      |
+--------------------+
| information_schema |
| mysql              |
| test               |
+--------------------+

The list of installed databases may vary, but will always include the minimum of mysql and information_schema. In most cases, the test database will also be installed automatically.

The preceding command (and commands for other MySQL programs such as mysql) may not work if the correct MySQL account does not exist. For example, the program may fail with an error, or you may not be able to view all databases. If you installed using the MSI packages and used the MySQL Server Instance Config Wizard, then the root user will have been created automatically with the password you supplied. In this case, you should use the -u root and -p options. (You will also need to use the -u root and -p options if you have already secured the initial MySQL accounts.) With -p, you will be prompted for the root password. For example:

C:\> C:\mysql\bin\mysqlshow -u root -p
Enter password: (enter root password here)
+--------------------+
|     Databases      |
+--------------------+
| information_schema |
| mysql              |
| test               |
+--------------------+

If you specify a database name, mysqlshow displays a list of the tables within the database:

C:\> C:\mysql\bin\mysqlshow mysql
Database: mysql
+---------------------------+
|          Tables           |
+---------------------------+
| columns_priv              |
| db                        |
| event                     |
| func                      |
| help_category             |
| help_keyword              |
| help_relation             |
| help_topic                |
| host                      |
| plugin                    |
| proc                      |
| procs_priv                |
| servers                   |
| tables_priv               |
| time_zone                 |
| time_zone_leap_second     |
| time_zone_name            |
| time_zone_transition      |
| time_zone_transition_type |
| user                      |
+---------------------------+

Use the mysql program to select information from a table in the mysql database:

C:\> C:\mysql\bin\mysql -e "SELECT Host,Db,User FROM mysql.db"
+------+--------+------+
| host | db     | user |
+------+--------+------+
| %    | test   |      |
| %    | test_% |      |
+------+--------+------+

For more information about mysqlshow and mysql, see Section 4.5.6, “mysqlshow — Display Database, Table, and Column Information”, and Section 4.5.1, “mysql — The MySQL Command-Line Tool”.

If you are running a version of Windows that supports services, you can set up the MySQL server to run automatically when Windows starts. See Section 2.3.5.7, “Starting MySQL as a Windows Service”.
