一、mysql_install_db说明

当MySQL的系统库(mysql系统库)发生故障或需要新加一个mysql实例时，需要初始化mysql数据库。

需要使用的命令：/usr/local/mysql/bin/mysql_install_db

#/usr/local/mysql/bin/mysql_install_db --help 可以查看帮助信息如下

Usage: /usr/local/mysql/bin/mysql_install_db [OPTIONS]

--basedir=path The path to the MySQL installation directory.

--cross-bootstrap For internal use. Used when building the MySQL system

tables on a different host than the target.

--datadir=path The path to the MySQL data directory.

--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.

--ldata=path The path to the MySQL data directory.

--rpm For internal use. This option is used by RPM files

during the MySQL installation process.
