NAME
mysql.server - MySQL server startup scriptSYNOPSIS
- mysql {start|stop}
DESCRIPTION
mysql.server is the script name as used within the MySQL source tree. The installed name might be different; for example, mysqld or mysql. In the following discussion, adjust the name mysql.server as appropriate for your system.
To start or stop the server manually using the mysql.server script, invoke it from the command line with start or stop arguments:
-
shell> mysql.server start shell> mysql.server stop
mysql.server changes location to the MySQL installation directory, then invokes mysqld_safe. To run the server as some specific user, add an appropriate user option to the [mysqld] group of the global /etc/my.cnf option file, as shown later in this section. (It is possible that you must edit mysql.server if you've installed a binary distribution of MySQL in a nonstandard location. Modify it to change location into the proper directory before it runs mysqld_safe. If you do this, your modified version of mysql.server may be overwritten if you upgrade MySQL in the future; make a copy of your edited version that you can reinstall.)
mysql.server stop stops the server by sending a signal to it. You can also stop the server manually by executing mysqladmin shutdown.
To start and stop MySQL automatically on your server, you must add start and stop commands to the appropriate places in your /etc/rc* files:
- * If you use the Linux server RPM package (MySQL-server-VERSION.rpm), or a native Linux package installation, the mysql.server script may be installed in the /etc/init.d directory with the name mysqld or mysql. See Section 2.5.5, lqInstalling MySQL on Linux Using RPM Packages from Oraclerq, for more information on the Linux RPM packages.

If you install MySQL from a source distribution or using a binary distribution format that does not install
mysql.server
automatically, you can install the script manually. It can be found in the
support-files
directory under the MySQL installation directory or in a MySQL source tree. Copy the script to the
/etc/init.d
directory with the name
mysql
and make it executable:
-
shell> cp mysql.server /etc/init.d/mysql shell> chmod +x /etc/init.d/mysql
After installing the script, the commands needed to activate it to run at system startup depend on your operating system. On Linux, you can use chkconfig:
-
shell> chkconfig --add mysql
On some Linux systems, the following command also seems to be necessary to fully enable the mysql script:
-
shell> chkconfig --level 345 mysql on
-
- * On FreeBSD, startup scripts generally should go in /usr/local/etc/rc.d/. Install the mysql.server script as /usr/local/etc/rc.d/mysql.server.sh to enable automatic startup. The rc(8) manual page states that scripts in this directory are executed only if their base name matches the *.sh shell file name pattern. Any other files or directories present within the directory are silently ignored.
-
*
As an alternative to the preceding setup, some operating systems also use
/etc/rc.local
or
/etc/init.d/boot.local
to start additional services on startup. To start up MySQL using this method, append a command like the one following to the appropriate startup file:
-
/bin/sh -c 'cd /usr/local/mysql; ./bin/mysqld_safe --user=mysql &'
-
- * For other systems, consult your operating system documentation to see how to install startup scripts.
mysql.server reads options from the [mysql.server] and [mysqld] sections of option files. For backward compatibility, it also reads [mysql_server] sections, but to be current you should rename such sections to [mysql.server].
You can add options for mysql.server in a global /etc/my.cnf file. A typical my.cnf file might look like this:
-
[mysqld] datadir=/usr/local/mysql/var socket=/var/tmp/mysql.sock port=3306 user=mysql [mysql.server] basedir=/usr/local/mysql
The mysql.server script supports the options shown in the following table. If specified, they must be placed in an option file, not on the command line. mysql.server supports only start and stop as command-line arguments.
Table 4.3. mysql.server Option-File Options
Option Name | Description |
Type
|
basedir | Path to MySQL installation directory |
directory name
|
datadir | Path to MySQL data directory |
directory name
|
pid-file | File in which server should write its process ID |
file name
|
service-startup-timeout | How long to wait for server startup |
integer
|
-
*
basedir=dir_name
The path to the MySQL installation directory.
-
*
datadir=dir_name
The path to the MySQL data directory.
-
*
pid-file=file_name
The path name of the file in which the server should write its process ID.
If this option is not given, mysql.server uses a default value of host_name.pid. The PID file value passed to mysqld_safe overrides any value specified in the [mysqld_safe] option file group. Because mysql.server reads the [mysqld] option file group but not the [mysqld_safe] group, you can ensure that mysqld_safe gets the same value when invoked from mysql.server as when invoked manually by putting the same pid-file setting in both the [mysqld_safe] and [mysqld] groups.
-
*
service-startup-timeout=seconds
How long in seconds to wait for confirmation of server startup. If the server does not start within this time, mysql.server exits with an error. The default value is 900. A value of 0 means not to wait at all for startup. Negative values mean to wait forever (no timeout).
