NAME
mysql.server - MySQL server startup script
SYNOPSIS
mysql {start|stop}
DESCRIPTION
MySQL distributions on Unix include a script named mysql.server, which
starts the server using mysqld_safe. It can be used on systems such as
Linux and Solaris that use System V-style run directories to start and
stop system services. It is also used by the OS X Startup Item for
MySQL.
Note
As of MySQL 5.7.6, for MySQL installation using an RPM
distribution, server startup and shutdown is managed by systemd on
several Linux platforms. On these platforms, mysql.server and
mysqld_safe are no longer installed because they are unnecessary.
For more information, see Section 2.5.10, "Managing MySQL Server
with systemd".
To start or stop the server manually using the mysql.server script,
invoke it with start or stop arguments:
shell> mysql.server start
shell> mysql.server stop
Before mysql.server starts the server, it changes location to the MySQL
installation directory, and then invokes mysqld_safe. To run the server
as some specific user, add an appropriate user option to the [mysqld]
group of the /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, so you should 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 mysql. See
Section 2.5.5, "Installing MySQL on Linux Using RPM Packages", for more
information on the Linux RPM packages.
Some vendors provide RPM packages that install a startup script under a
different name such as mysqld.
If you install MySQL from a source distribution or using a binary
distribution format that does not install mysql.server automatically,
you can install it manually. The script can be found in the
support-files directory under the MySQL installation directory or in a
MySQL source tree. Copy it to the /etc/init.d directory with the name
mysql, and then make it executable:
shell> cp mysql.server /etc/init.d/mysql
shell> chmod +x /etc/init.d/mysql
Note
Older Red Hat systems use the /etc/rc.d/init.d directory rather
than /etc/init.d. Adjust the preceding commands accordingly.
Alternatively, first create /etc/init.d as a symbolic link that
points to /etc/rc.d/init.d:
shell> cd /etc
shell> ln -s rc.d/init.d .
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/. 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. In other words, on FreeBSD, you should
install the mysql.server script as /usr/local/etc/rc.d/mysql.server.sh
to enable automatic startup.
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 /etc/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 following options. 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.
o --basedir=dir_name
The path to the MySQL installation directory.
o --datadir=dir_name
The path to the MySQL data directory.
o --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 invoke using mysql.server as when invoked manually by
putting the same pid-file setting in both the [mysqld_safe] and
[mysqld] groups.
o --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).
