mysql.server \- MySQL server startup script
.SH "SYNOPSIS"
.HP \w'\fBmysql\ {start|stop}\fR\ 'u
\fBmysql {start|stop}\fR
.SH "DESCRIPTION"
.PP
MySQL distributions on Unix and Unix\-like system include a script named
\fBmysql\&.server\fR, which starts the MySQL server using
\fBmysqld_safe\fR\&. 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 macOS Startup Item for MySQL\&.
.PP
\fBmysql\&.server\fR
is the script name as used within the MySQL source tree\&. The installed name might be different (for example,
\fBmysqld\fR
or
\fBmysql\fR)\&. In the following discussion, adjust the name
\fBmysql\&.server\fR
as appropriate for your system\&.

For some Linux platforms, MySQL installation from RPM or Debian packages includes systemd support for managing MySQL server startup and shutdown\&. On these platforms,
\fBmysql\&.server\fR
and
\fBmysqld_safe\fR
are not installed because they are unnecessary\&. For more information, see
Section\ \&2.5.9, \(lqManaging MySQL Server with systemd\(rq\&.

.PP
To start or stop the server manually using the
\fBmysql\&.server\fR
script, invoke it from the command line with
start
or
stop
arguments:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql\&.server start\fR
shell> \fBmysql\&.server stop\fR
.fi
.if n \{\
.RE
.\}
.PP
\fBmysql\&.server\fR
changes location to the MySQL installation directory, then invokes
\fBmysqld_safe\fR\&. 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
\fBmysql\&.server\fR
if you\*(Aqve installed a binary distribution of MySQL in a nonstandard location\&. Modify it to change location into the proper directory before it runs
\fBmysqld_safe\fR\&. If you do this, your modified version of
\fBmysql\&.server\fR
may be overwritten if you upgrade MySQL in the future; make a copy of your edited version that you can reinstall\&.)
.PP
\fBmysql\&.server stop\fR
stops the server by sending a signal to it\&. You can also stop the server manually by executing
\fBmysqladmin shutdown\fR\&.
.PP
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:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If you use the Linux server RPM package (MySQL\-server\-\fIVERSION\fR\&.rpm), or a native Linux package installation, the
\fBmysql\&.server\fR
script may be installed in the
/etc/init\&.d
directory with the name
mysqld
or
mysql\&. See
Section\ \&2.5.4, \(lqInstalling MySQL on Linux Using RPM Packages from Oracle\(rq, for more information on the Linux RPM packages\&.

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If you install MySQL from a source distribution or using a binary distribution format that does not install
\fBmysql\&.server\fR
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
\fBmysql\fR
and make it executable:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBcp mysql\&.server /etc/init\&.d/mysql\fR
shell> \fBchmod +x /etc/init\&.d/mysql\fR
.fi
.if n \{\
.RE
.\}
.sp
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
\fBchkconfig\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBchkconfig \-\-add mysql\fR
.fi
.if n \{\
.RE
.\}
.sp
On some Linux systems, the following command also seems to be necessary to fully enable the
\fBmysql\fR
script:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBchkconfig \-\-level 345 mysql on\fR
.fi
.if n \{\
.RE
.\}
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
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\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
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:
.sp
.if n \{\
.RS 4
.\}
.nf
/bin/sh \-c \*(Aqcd /usr/local/mysql; \&./bin/mysqld_safe \-\-user=mysql &\*(Aq
.fi
.if n \{\
.RE
.\}
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
For other systems, consult your operating system documentation to see how to install startup scripts\&.
.RE
.PP
\fBmysql\&.server\fR
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]\&.
.PP
You can add options for
\fBmysql\&.server\fR
in a global
/etc/my\&.cnf
file\&. A typical
my\&.cnf
file might look like this:
.sp
.if n \{\
.RS 4
.\}
.nf
[mysqld]
datadir=/usr/local/mysql/var
socket=/var/tmp/mysql\&.sock
port=3306
user=mysql
[mysql\&.server]
basedir=/usr/local/mysql
.fi
.if n \{\
.RE
.\}
.PP
The
\fBmysql\&.server\fR
script supports the options shown in the following table\&. If specified, they
\fImust\fR
be placed in an option file, not on the command line\&.
\fBmysql\&.server\fR
supports only
start
and
stop
as command\-line arguments\&.

If this option is not given,
\fBmysql\&.server\fR
uses a default value of
\fIhost_name\fR\&.pid\&. The PID file value passed to
\fBmysqld_safe\fR
overrides any value specified in the
[mysqld_safe]
option file group\&. Because
\fBmysql\&.server\fR
reads the
[mysqld]
option file group but not the
[mysqld_safe]
group, you can ensure that
\fBmysqld_safe\fR
gets the same value when invoked from
\fBmysql\&.server\fR
as when invoked manually by putting the same
pid\-file
setting in both the
[mysqld_safe]
and
[mysqld]
groups\&.

.sp
How long in seconds to wait for confirmation of server startup\&. If the server does not start within this time,
\fBmysql\&.server\fR
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)\&.
