Hi everyone, my librenms operates on centos 7.
When I run ./daily.sh, everything is good except the codebase:
[root@localhost librenms]# ./daily.sh
Re-running /opt/librenms/daily.sh as librenms user
Updating to latest codebase FAIL
fatal: unable to access ‘https://github.com/librenms/librenms.git/’: Could not resolve host: github.com; Unknown error
Updating Composer packages OK
Updating SQL-Schema OK
Updating submodules OK
Cleaning up DB OK
Fetching notifications OK
Caching PeeringDB data OK
I have tried to disable firewall using systemctl disable firewalld, however the error remains. What should I do now ?
And when I run ./validate.php, there’s something wrong with the cron job.
[root@localhost librenms]# ./validate.php

Have you followed the installation guide https://docs.librenms.org/#Installation/Installation-CentOS-7-Apache/ where SELinux is mentioned?
systemctl disable firewalld
just disables it on next boot. I think you also have to stop the ervice via
service firewalld stop
Is your server running behind another firewall?
Seems like it doesn’t have working DNS.
Yes Jarod2801, I do follow the install guide on docs.librenms.org using Nginx not Apache. But I still follow the guides in the SELinux step. I’ve tried to use service firewalld stop and restart Centos but no impact.
I have no idea if my server running behind another firewall or not. How to get that information ?
Hi murrant,
I’m still new in this field so I don’t get your point. What should I do to have working DNS ?
When you ping GitHub.com from CLI, what is the result?
Thanks Jarod2801, I can’t ping github.com at first and it turns out that the Wired Connection was off. After turning on the Wired Connection on Centos, the ./daily.sh runs smoothly:
[root@localhost librenms]# ./daily.sh
Re-running /opt/librenms/daily.sh as librenms user

Updating Composer packages OK

However, when I try to ping github.com again:
[root@localhost librenms]# ping github.com
PING github.com (13.250.177.223) 56(84) bytes of data.
^C
— github.com ping statistics —
1113 packets transmitted, 0 received, 100% packet loss, time 1113916ms
I’ve been waiting for 20mins but nothing happen. If you have any suggestion for this issue or the cronjob error as well, please tell me.
A little update for the cronjob error:
[root@localhost librenms]# ./validate.php

So I need config the cronjob base on the guide again or something else ?
Have you checked /etc/cron.d on the file librenms.
Is it in there?
Yes Jarod2801, here is the librenms profile:
[root@localhost /]# cd /etc/cron.d
[root@localhost cron.d]# ls
0hourly librenms raid-check sysstat
[root@localhost cron.d]# cat /etc/cron.d/librenms

Is LibreNMS installed in /opt/librenms?
Can you post the logfiles of Cron?
Hi Jarod2801,
I think it was installed in opt/librenms cause I follow the installation guide on https://docs.librenms.org/#Installation/Installation-CentOS-7-Nginx/.
How to show the logfiles of Cron, where is this Cron locate at ?
Here is my log files. I’m having the same problem.
sudo tail /var/log/cron
