2.3.4.6 Starting MySQL from the Windows Command Line
The MySQL server can be started manually from the command line. This can be done on any version of Windows.
MySQL Notifier can also be used to start/stop/restart the MySQL server.
To start the mysqld server from the command line, you should start a console window (or “DOS window”) and enter this command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqld"
The path to mysqld may vary depending on the install location of MySQL on your system.
You can stop the MySQL server by executing this command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqladmin" -u root shutdown
If the MySQL root
user account has a password, you need to invoke mysqladmin with the -p
option and supply the password when prompted.
This command invokes the MySQL administrative utility mysqladmin to connect to the server and tell it to shut down. The command connects as the MySQL root
user, which is the default administrative account in the MySQL grant system.
Users in the MySQL grant system are wholly independent from any operating system users under Microsoft Windows.
If mysqld doesn't start, check the error log to see whether the server wrote any messages there to indicate the cause of the problem. By default, the error log is located in the C:\Program Files\MySQL\MySQL Server 5.7\data
directory. It is the file with a suffix of .err
, or may be specified by passing in the --log-error
option. Alternatively, you can try to start the server with the --console
option; in this case, the server may display some useful information on the screen that will help solve the problem.
The last option is to start mysqld with the --standalone
and --debug
options. In this case, mysqld writes a log file C:\mysqld.trace
that should contain the reason why mysqld doesn't start. See Section 28.5.3, “The DBUG Package”.
Use mysqld --verbose --help to display all the options that mysqld supports.
