我试图在我的本地机器上configurationMonit以了解它是如何工作的，但是我有一些问题。
我想要做的是获得任何Monit启动和运行正确的证据， 并且实际上是在监控某些事情。 所以我的/etc/monit/monitrc看起来像
set daemon 60 set logfile /var/log/monit.log set idfile /var/lib/monit/id set statefile /var/lib/monit/state set eventqueue basedir /var/lib/monit/events slots 100 set httpd port 2812 and allow username:password check process apache2 with pidfile /usr/local/apache/logs/apache2.pid start program = "/etc/init.d/apache2 start" stop program = "/etc/init.d/apache2 stop" if failed port 6543 protocol http then exec "/usr/bin/touch /tmp/monit"
如果我理解正确，因为Apache不监听端口6543（这只是一个随机数），我应该得到一个错误，所以应该创build文件/tmp/monit 。 所以我开始监视
sudo service monit start sudo monit monitor apache2
不幸的是没有创build这样的文件。 Web控制台显示apache错误 – execution failed 。 日志说'apache2' failed to start 。
我究竟做错了什么？
编辑正如在评论中所build议的，我用详细模式运行monit
monit -vv monitor apache2
（在评论中build议的确切命令失败）。 输出是

PID文件通常位于/var/run 。
在你的/etc/monit/monitrc你引用了一个在/usr/local/apache/logs/apache2.pid下的pidfile。
尝试改变这个来匹配/var/run中的Apache的pid文件。
它应该是以下之一：
/var/run/httpd.pid
要么
/var/run/apache2.pid
