NAME

6       mysql_install_db - initialize MySQL data directory
7

SYNOPSIS

9       mysql_install_db [options]
10

DESCRIPTION

12       mysql_install_db initializes the MySQL data directory and creates the
13       system tables that it contains, if they do not exist.
14
15       To invoke mysql_install_db, use the following syntax:
16
17           shell> mysql_install_db [options]
18
19       Because the MySQL server, mysqld, needs to access the data directory
20       when it runs later, you should either run mysql_install_db from the
21       same account that will be used for running mysqld or run it as root and
22       use the --user option to indicate the user name that mysqld will run
23       as. It might be necessary to specify other options such as --basedir or
24       --datadir if mysql_install_db does not use the correct locations for
25       the installation directory or data directory. For example:
26
27           shell> bin/mysql_install_db --user=mysql \
28                    --basedir=/opt/mysql/mysql \
29                    --datadir=/opt/mysql/mysql/data
30
31       mysql_install_db needs to invoke mysqld with the --bootstrap and
32       --skip-grant-tables options. If MySQL was configured with the
33       --disable-grant-options option, --bootstrap and --skip-grant-tables
34       will be disabled (see Section 2.11.4, “MySQL Source-Configuration
35       Options”). To handle this, set the MYSQLD_BOOTSTRAP environment
36       variable to the full path name of a server that has all options
37       enabled.  mysql_install_db will use that server.
38
39           Note
40           If you have set a custom TMPDIR variable when performing the
41           installation, and the specified directory is not accessible, the
42           execution of mysql_install_db may fail. You should unset TMPDIR, or
43           set TMPDIR to point to the system temporary directory (usually
44           /tmp).
45
46       mysql_install_db supports the following options, which can be specified
47       on the command line or in the [mysql_install_db] and (if they are
48       common to mysqld) [mysqld] groups of an option file. Other options are
49       passed to mysqld. For information about option files, see
50       Section 4.2.3.3, “Using Option Files”.  mysql_install_db also supports
51       the options for processing option files described at Section 4.2.3.3.1,
52       “Command-Line Options that Affect Option-File Handling”.
53
54       ·   --basedir=path
55
56           The path to the MySQL installation directory.
57
58       ·   --force
59
60           Cause mysql_install_db to run even if DNS does not work. In that
61           case, grant table entries that normally use host names will use IP
62           addresses.
63
64       ·   --datadir=path, --ldata=path
65
66           The path to the MySQL data directory.
67
68       ·   --rpm
69
70           For internal use. This option is used by RPM files during the MySQL
71           installation process.
72
73       ·   --skip-name-resolve
74
75           Use IP addresses rather than host names when creating grant table
76           entries. This option can be useful if your DNS does not work.
77
78       ·   --srcdir=path
79
80           For internal use. The directory under which mysql_install_db looks
81           for support files such as the error message file and the file for
82           populating the help tables. This option was added in MySQL 5.1.14.
83
84       ·   --user=user_name
85
86           The login user name to use for running mysqld. Files and
87           directories created by mysqld will be owned by this user. You must
88           be root to use this option. By default, mysqld runs using your
89           current login name and files and directories that it creates will
90           be owned by you.
91
92       ·   --verbose
93
94           Verbose mode. Print more information about what the program does.
95
96       ·   --windows
97
98           For internal use. This option is used for creating Windows
99           distributions.
