Starting the MySQL Server

Starting the MySQL serer on a Linux machine

You can start the MySQL server with the following command:

shell> bin/safe_mysqld &

Starting MySQL on Win95 / Win98

MySQL uses TCP/IP to connect a client to a server. (This will allow any machine on your network to connect to your MySQL server). Because of this, you must install TCP/IP on your machine before starting MySQL. You can find TCP/IP on your Windows CD-ROM.

Note that if you are using an old Win95 release (for example OSR2), it's likely that you have an old Winsock package! MySQL requires Winsock 2! You can get the newest Winsock from Microsoft. Win98 has as default the new Winsock 2 library, so the above doesn't apply for Win98.

To start the mysqld server, you should start a MS-DOS window and type:


This will start mysqld in the background without a window.

You can kill the MySQL server by executing:

C:\mysql\bin\mysqladmin -u root shutdown

Note that Win95/Win98 don't support creation of named pipes. On Win95/Win98, you can only use named pipes to connect to a remote MySQL running on an NT server.

If mysqld doesn't start please check whether or not the `\mysql\mysql.err' file contains any reason for this. You can also try to start it with mysqld --standalone; In this case you may get some useful information on the screen that may help solve this.

The last option is to start mysqld with --debug. In this case mysqld will write a log file in `\mysqld.trace' that should contain the reason why mysqld doesn't start. If you make a bug report about this, please only send the lines where something seams to go wrong to the mailing list!

Starting MySQL on NT

The Win95/Win98 section also applies to MySQL on NT, with the following differences:

To get MySQL to work with TCP/IP, you must install service pack 3 (or newer)!

For NT, the server name is mysqld-nt. Normally you should install MySQL as a service on NT:

C:\mysql\bin\mysqld-nt --install

(You could use the mysqld or mysqld-opt servers on NT, but those cannot be started as a service or use named pipes.)

You can start and stop the MySQL service with:

NET STOP mysql

Note that in this case you can't use any other options for mysqld-nt!

You can also run mysqld-nt as a standalone program on NT if you need to start mysqld-nt with any options! If you start mysqld-nt without options on NT, mysqld-nt tries to starts itself as a service with the default service options. If you have stopped mysqld-nt, you have to start it with NET START mysql.

The service is installed with the name MySql. Once installed, it must be started using Services Control Manager (SCM) Utility (found in Control Panel) or by using the NET START MySQL command. If any options are desired, they must be specified as "Startup parameters" in the SCM utility before you start the MySQL service. Once running, mysqld-nt can be stopped using mysqladmin or from the SCM utility or by using the command NET STOP MySQL. If you use SCM to stop mysqld-nt, there is a strange message from SCM about mysqld shutdown normally. When run as a service, mysqld-nt has no access to a console and so no messages can be seen.

On NT you can get the following service error messages:

Permission Denied Means that it cannot find mysqld-nt.exe
Cannot Register Means that the path is incorrect

If you have problems installing mysqld-nt as a service, try starting it with the full path:

C:\mysql\bin\mysqld-nt --install

If this doesn't work, you can get mysqld-nt to start properly by fixing the path in the registry!

If you don't want to start mysqld-nt as a service, you can start it as follows:

C:\mysql\bin\mysqld-nt --standalone


C:\mysql\bin\mysqld --standalone --debug

The last version gives you a debug trace in `C:\mysqld.trace'.
