The historical behavior is 'normal' to creates a root user that can login without password, which can be insecure. The default behavior 'socket' sets an invalid root password but allows the system root user to login as MariaDB root without a password. --auth-root-socket-user=user Used with --auth-root-authentication-method=socket. It specifies the name of the second MariaDB root account, as well as of the system account allowed to access it. Defaults to the value of --user. --basedir=path The path to the MariaDB installation directory. --builddir=path 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. --cross-bootstrap For internal use. Used when building the MariaDB system tables on a different host than the target. --datadir=path The path to the MariaDB data directory. --no-defaults Don't read default options from any option file. --defaults-extra-file=name Read this file after the global files are read. --defaults-file=name Only read default options from the given file name. --defaults-group-suffix=name In addition to the given groups, read also groups with this suffix --force Causes mysql_install_db to run even if DNS does not work. In that case, grant table entries that normally use hostnames will use IP addresses. --help Display this help and exit. --ldata=path The path to the MariaDB data directory. Same as --datadir. --rpm For internal use. This option is used by RPM files during the MariaDB installation process. --skip-name-resolve Use IP addresses rather than hostnames when creating grant table entries. This option can be useful if your DNS does not work. --skip-test-db Don't install a test database. --srcdir=path The path to the MariaDB source directory. This option uses the compiled binaries and support files within the source tree, useful for if you don't want to install MariaDB yet and just want to create the system tables. --user=user_name The login username 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. --group=group_name The login group to use for running mysqld. Files and directories created by mysqld will be owned by this group. You must be root to use this option. By default mysqld runs using your current group and files and directories that it creates will be owned by you. All other options are passed to the mysqld program EOF exit 1 } s_echo() { if test "$in_rpm" -eq 0 -a "$cross_bootstrap" -eq 0 then echo "$1" fi } link_to_help() { echo echo "The latest information about mysql_install_db is available at" echo "https://mariadb.com/kb/en/installing-system-tables-mysql_install_db" } parse_arg() { echo "$1" | sed -e 's/^[^=]*=//' } parse_arguments() { # We only need to pass arguments through to the server if we don't # handle them here.
