I'm running Apache, and trying to monitor it wiht Monit. The monitoring seems to work fine, but when Apache is down, Monit does not succeed to start it.
Monit does detect that it's down, but the start command fails.
Below is the monit config
check process httpd with pidfile /var/run/httpd.pid
start program = "/usr/bin/apachestart start"
stop program = "/etc/init.d/httpd stop"
if failed host 127.0.0.1 port 80
protocol http then restart
if 5 restarts within 5 cycles then timeout
This refers to the startup script of Apache, which includes the following:
# cat /usr/bin/apachestart
## start Apache with default settings
ulimit -l 256;
ulimit -s 56000;
/usr/sbin/apachectl start;
This script sets a couple of params which seem to be required for this specific Apache/PHP setup. Works fine when run from the commandline as root, but apparently, for Monit, it's somehow a problem.
When running monit in debug mode (started with "monit -Iv"), I get the following
monit: pidfile '/var/run/httpd.pid' does not exist
'httpd' process is not running

Any ideas why monit cannot start the Apache?
