man 一下 mysql_install_db
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.
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> bin/mysql_install_db --user=mysql \
--basedir=/opt/mysql/mysql \
--datadir=/opt/mysql/mysql/data
