problems with starting by crond

[tip78]

hello

my os is centos 6.5

a simple script:

#!/bin/sh

/path/to/file/mta-server >/dev/null 2>&1 &

(or mta-server -d)

is not working from crond but perfectly starting server if runs by hands

why?

please expand the script. Check if the server is running before you start it. If it is already running you should not attempt to start another instance. That's bad practice. Also, do not send the output from the server to /dev/null, use the -d switch to deamonize, that's what it is there for. That way, when the server fails to start or crashes, the output can be recorded.

If the crond fails to execute the script, check the syslog to see why it crashed. Some distributions also send a mail to your inbox for every failed cronjob.
