NAME
mysql_install_db - initialize MySQL data directory
SYNOPSIS
mysql_install_db [options]
DESCRIPTION
mysql_install_db initializes the MySQL data directory and creates the
system tables that it contains, if they do not exist. mysql_install_db
is a shell script and is available only on Unix platforms. (As of MySQL
5.6, mysql_install_db is a Perl script and can be used on any system
with Perl installed.)
To invoke mysql_install_db, use the following syntax:
shell> mysql_install_db [options]
Because the MySQL server, mysqld, needs to access the data directory
when it runs later, you should either run mysql_install_db from the
same system account that will be used for running mysqld or run it as
root and use the --user option to indicate the user name that mysqld
will run as. It might be necessary to specify other options such as
--basedir or --datadir if mysql_install_db does not use the correct
locations for the installation directory or data directory. For
example:
shell> scripts/mysql_install_db --user=mysql \
--basedir=/opt/mysql/mysql \
--datadir=/opt/mysql/mysql/data
mysql_install_db needs to invoke mysqld with the --bootstrap and
--skip-grant-tables options.
Note
If you have set a custom TMPDIR environment variable when
performing the installation, and the specified directory is not
accessible, mysql_install_db may fail. If so, unset TMPDIR or set
TMPDIR to point to the system temporary directory (usually /tmp).
mysql_install_db supports the following options, which can be specified
on the command line or in the [mysql_install_db] group of an option
file. (Options that are common to mysqld can also be specified in the
[mysqld] group.) Other options are passed to mysqld. For information
about option files, see Section 4.2.3.3, “Using Option Files”.
mysql_install_db also supports the options for processing option files
described at Section 4.2.3.4, “Command-Line Options that Affect Option-
File Handling”.
· --basedir=path
The path to the MySQL installation directory.
· --datadir=path, --ldata=path
The path to the MySQL data directory.
· --force
Cause mysql_install_db to run even if DNS does not work. Grant
table entries that normally use host names will use IP addresses.
· --rpm
For internal use. This option is used during the MySQL installation
process for install operations performed using RPM packages.
· --skip-name-resolve
Use IP addresses rather than host names when creating grant table
entries. This option can be useful if your DNS does not work.
· --srcdir=path
For internal use. This option specifies the directory under which
mysql_install_db looks for support files such as the error message
file and the file for populating the help tables.
· --user=user_name
The system (login) user name to use for running mysqld. Files and
directories created by mysqld will be owned by this user. You must
be root to use this option. By default, mysqld runs using your
current login name and files and directories that it creates will
be owned by you.
· --verbose
Verbose mode. Print more information about what the program does.
· --windows
For internal use. This option is used for creating Windows
distributions.
