Post-install ./validate.php showing PHP timezone and Cron failures

Help

Greetings!

I’ve just discovered LibreNMS and we’ve decided to deploy it, however I’ve run in to a few problems with the validate.php final step.

Environment:
I’ve started with a fresh install of Ubuntu 16.04 to a VM, and followed the install documentation here: http://docs.librenms.org/Installation/Installation-Ubuntu-1604-Apache/

root@LIT-UP-NMS-01:/opt/librenms# uname -a
Linux LIT-UP-NMS-01 4.4.0-67-generic #88-Ubuntu SMP Wed Mar 8 16:34:45 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

root@LIT-UP-NMS-01:/etc# cat os-release 
NAME="Ubuntu"
VERSION="16.04.2 LTS (Xenial Xerus)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 16.04.2 LTS"

Validate.php Output:

[FAIL]  Discovery has never run, check the cron job
[FAIL]  The poller has never run, check the cron job

I’ve ensured that my two php.ini files have the correct timezone as required by the documentation:

/etc/php/7.0/apache2/php.ini Date config:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
;date.timezone = "America/Chicago"

/etc/php/7.0/cli/php.ini Date config:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
;date.timezone = "America/Chicago"

I’ve even gone as far as to create a test.php file with an echo of the timezone, as seen here with it’s output:

root@LIT-UP-NMS-01:/opt/librenms# cat test.php
#!/usr/bin/env php
<?php
echo date_default_timezone_get();
?> 
root@LIT-UP-NMS-01:/opt/librenms# ./test.php 
America/Chicago

Is this a bug in the current validate.php file?

As for the cron failures, I feel like either steps are missing from the cron installation (I don’t recall simply copying a file to activate cron jobs), or I have failed to prepare the Ubuntu installation completely for LibreNMS.

Any help would be appreciated - thank you in advance!

You need to remove the semi-colin ; in front of your timezone line

I’m looking at the updating the documentation as soon as I figure out the missing cron step :slight_smile:

I believe you may just need:

systemctl restart crond

I feel like an idiot! My experience has mostly just been scripting in tcsh, so the all mighty # comments out lines in my world. Thanks for letting me know - it definitely fixed the issue.

As for the cron errors - I don’t have crond, it seems:

root@LIT-UP-NMS-01:/opt/librenms# systemctl restart crond
Failed to restart crond.service: Unit crond.service not found.

However, when I check services I do see a cron entry, and it is started:

root@LIT-UP-NMS-01:/opt/librenms# service --status-all | grep -i cron
 [ + ]  cron

Any ideas?

Not sure I’m pretty clueless when it comes to Centos7 and cron

I am using RHEL7 (which is what CENTOS7 is based off of). For me I just needed to copy /opt/librenms/librenms.nonroot.cron to /etc/cron.d/ – I am pretty sure no restart of cron was required.

I suppose it must have just taken a while. Things appear to be normal now:

Please don’t post on old threads. You have to php.ini files, you only updated the apache php.ini, not the cli php.ini.
