Hello,
I'm trying to configure a daemon (I'm doing tests with "crond" daemon) to send me an
email after daemon restart. My "crond.service" file is:
# /etc/systemd/system/crond.service
[Unit]
Description=Command Scheduler
After=auditd.service systemd-user-sessions.service time-sync.target
#OnFailure=crond-notify-email@%i.service
[Service]
EnvironmentFile=/etc/sysconfig/crond
ExecStart=/usr/sbin/crond -n $CRONDARGS
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
Restart=on-failure
RestartSec=10s
ExecStartPost=/bin/sh -c "/etc/systemd/system/test.sh"
[Install]
WantedBy=multi-user.target
My "test.sh" is very simple:
#!/bin/sh
echo "CROND is restarting" | /usr/bin/mailx -s "crond failure notification"
myemailaddress@mydomain
As you can see, I have added lines "Restart=on-failure", "RestartSec=10s" and " ExecStartPost=/bin/sh -c
"/etc/systemd/system/test.sh"" to the original crond.service daemon file. Then, I run "systemctl daemon-reconfigure" and, from one console, I run
"kill -9 `pidof cron`" for restarting crond daemon. After it, I receive an email... But now, if I run again ""kill -9 `pidof cron`", I don't receive
any mail... I have notice that if I run "systemctl daemon-reload" and then kill crond process, mail is sent perfectly... but if I don't run "systemctl
daemon-reload", mail is sent ONLY first time...
Why?
What is "status" showing (systemctl status crond)? For both cases
(first/second kill)? Any differences?
