How to start xinetd after server reboot

[Shawn L]

Hi,

One of our servers was rebooted yesterday, but somehow the xinetd was not start after reboot. What can I do to make it automatically start each time after server reboot? Thanks in advance.

Here is the output of chkconfig:

Code: Select all

...
xinetd          0:off   1:off   2:off   3:on    4:on    5:on    6:off
...
xinetd based services:
        chargen-dgram:  off
        chargen-stream: off
        daytime-dgram:  off
        daytime-stream: off
        discard-dgram:  off
        discard-stream: off
        echo-dgram:     off
        echo-stream:    off
        nrpe:           on
        rsync:          off
        tcpmux-server:  off
        time-dgram:     off
        time-stream:    off

I think you're ok actually. Here is the output of chkconfig from a test machine here that's been running for
uptime 12:44:34 up 16 days

Code: Select all

xinetd          0:off   1:off   2:off   3:on    4:on    5:on    6:off

xinetd based services:
        chargen-dgram:  off
        chargen-stream: off
        daytime-dgram:  off
        daytime-stream: off
        discard-dgram:  off
        discard-stream: off
        echo-dgram:     off
        echo-stream:    off
        nrpe:           on
        nsca:           on
        tcpmux-server:  off
        time-dgram:     off
        time-stream:    off

But, in fact, the xinetd was not started after reboot. Do you have any idea what could cause this problem? This morning, another server was rebooted, and xinetd was not running on that server.

Code: Select all

[root@server ~]# service xinetd status
xinetd dead but pid file exists
[root@server ~]# service xinetd restart
Stopping xinetd:                                           [FAILED]
Starting xinetd:                                           [  OK  ]
[root@server~]# service xinetd status
xinetd (pid  29095) is running...

Which distro?

[lmiltchev]

Do you find any clues in the /var/log/messages?

Run the following commands and show the output in code wraps:

Code: Select all

echo $PATH
cat /etc/init.d/xinetd

[gormank]

If the pid file existed after a restart, the service died unexpectedly. Since the file existed, the service didn't restart.
The question is not how to make it start, but why didn't it shut down correctly. We could also ask why a starting service doesn't check the pid and verify that a matching process exists, but that's the next step.

The dsitro is RHEL 6.6.

In the message file, I saw lots of kernel IO errors. Could that be the problem?

[rkennedy]

Is your VM running off a SAN or NAS? This could be an issue. Please post the output @lmiltchev mentioned -

Code: Select all

echo $PATH
cat /etc/init.d/xinetd

Yes, IO errors can be fatal. Do you know why the machine was shutdown as @gormank mentioned?

I am not managing that server, I am not pretty sure why they rebooted it.
