Re: Apache will not start/stop with Monit, unless..

[Martin Pala]

Monit sets spartan environment wen execution the program (for security 
reasons). It is likely your apache startup script depends on some environment 
variable which is not set by monit.

You can log the start/stop script output by wrapping it for example like this:

start program = "/bin/bash -c '/etc/init.d/httpd start' > /tmp/httpd_start.out 
2>&1'"
