mysql_install_db — initialize MariaDB data directory
mysql_install_db initializes the MariaDB data directory and creates the system tables that it contains, if they do not exist.
To invoke mysql_install_db, use the following syntax:
shell> mysql_install_db [options]
Because the MariaDB server, mysqld, needs to access the data directory when it runs later, you should either run mysql_install_db from the same 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> bin/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 (see Section 2.3.2, “Typical configure Options”). If MariaDB was configured with the --disable-grant-options option, --bootstrap and --skip-grant-tables will be disabled. To handle this, set the MYSQLD_BOOTSTRAP environment variable to the full path name of a server that has all options enabled. mysql_install_db will use that server.
mysql_install_db supports the following options, which can be specified on the command line or in the [mysql_install_db] and (if they are common to mysqld) [mysqld] option file groups.
The path to the MariaDB installation directory.
If using --srcdir with out-of-directory builds, you will need to set this to the location of the build directory where built files reside..
For internal use. Used when building the MariaDB system tables on a different host than the target..
The path to the MariaDB data directory.
Set filename as the file to read default options from after the global defaults files has been read. Must be given as first option.
Set filename as the file to read default options from, override global defaults files. Must be given as first option.
In addition to the given groups, also read groups with this suffix.
Cause mysql_install_db to run even if DNS does not work. In that case, grant table entries that normally use host names will use IP addresses.
Display a help message and exit.
Do not read default options from any option file. This must be given as the first argument.
Print the program argument list and exit. This must be given as the first argument.
For internal use. This option is used by RPM files during the MariaDB installation process.
Use IP addresses rather than host names when creating grant table entries. This option can be useful if your DNS does not work.
For internal use. 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.4.
The 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 mode. Print more information about what the program does.
For internal use. This option is used for creating Windows distributions.
