Please note there's a delay when starting up the daemon. I watched monit log till I saw everything was up. Then I did not get that error for status. There is also some editing you need to do (at least for Apache PID location in config file and probably others) on Ubuntu repo default install. You also need to copy the conf's you are using to conf dir. – Lawford

This is already already the case with me, and I was able to control monit earlier, but I no longer can. – Novgorod

Answer 2

Sometimes the problem appears because loopback interface is down . We should bring up the lo interface as follow

root@server:~# ifup lo

Really? Why would lo ever be down? If your loopback interface is down you probably have other problems. – Nyx

NO. sudo ifconfig shows interfaces up or down. If down, then run what you have in answer. But: I have never witnessed loopback going down in all my years w/ Linux. (since ~'93) – Lawford

@bshea Maybe I was agree with you before this happens . But my experience says everything may happen . – Doge
