MAC OS X：已安装的MySQL，无法在/ Library / StartupItems /目录下找到MySQLCOM /目录

Question

我正在使用Mac OS X Yosemite（版本：10.10.5），我想将MySQL用作我的网络应用程序的数据库。

我下载了MySQL - “mysql-5.7.10-osx10.9-x86_64.dmg”，并成功安装了它。

我正在遵循以下步骤： http://geeksww.com/tutorials/database_management_systems/mysql/installation/how_to_download_and_install_mysql_on_mac_os_x.php

我在这一步 -

    **"Install and setup auto start package for MySQL on OS X":**
    you should now be able to start MySQL running the following command in OS X Terminal window 

    $ sudo /Library/StartupItems/MySQLCOM/MySQLCOM start

但是我无法找到/ Library / StartupItems /目录下的MySQLCOM目录

    [Terminal]:$ pwd
    /Library/StartupItems

    [Terminal]:$ ls -l
    total 0
