mysql多实例实例化数据库

实例化数据库：/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/m_data/nduoa/db

启动实例数据库： /usr/local/mysql/bin/mysqld_multi --defaults-extra-file=/usr/local/mysql/etc/my.cnf --user=mysql start 3307

停止实例数据库：/usr/local/mysqlinstance/bin/mysqld_multi --defaults-extra-file=/usr/local/mysqlinstance/etc/my.cnf --user=root --password=aibei1010 stop 3310
