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?
Thanks.
