那么在下面的情况下是什么导致了这个错误呢？
- /etc/init.d/monit 存在
- 安装使用
sudo apt-get install monit
通过 apt 标准安装
vagrant@vagrant-ubuntu-trusty-64:~$ sudo apt-get install monit

我正在使用 vagrant 创建运行 ubuntu/trusty 14.04 的虚拟机。
/etc/init.d/monit start似乎有效
vagrant@vagrant-ubuntu-trusty-64:~$ sudo /etc/init.d/monit start
* Starting daemon monitor monit /etc/monit/conf.d/postfix.conf:11: Warning: hostname did not resolve 'INSERT_THE_RELAY_HOST'
[ OK ]

服务名称实际上是mmonit，不是monit。 :)
sudo service mmonit start作品
