nextcloud PiHole web admin pages - conflict

Troubleshooting
1

I have installed in this order PiHole, Nextcloud (talk),Motion eye, UrBackup, No-IP, this services are running :
redis-server
mariadb
php7.3-fpm
lighttpd
coturn
urbackupsrv
motioneye
noip2
cron
dropbear
pihole-FTL
dietpi-ramlog
dietpi-preboot
dietpi-boot
dietpi-postboot
dietpi-wifi-monitor inactive (dead).

After installing Nextcloud(talk), I couldn’t access PiHole admin page, so I run this command pihole-r , and I gain access to PiHole, but I cant open nextcloud.
All other web pages for MotionEYE and UrBackup are functioning ok.

How I can resolve this conflict?

and how I can change port for nextcloud?

Hi,

many thanks for your message. Do you know what option you have selected while running pihole -r. Was it Repair or Reconfigure. Because Reconfigure will replace DietPi lighttpd configuration with a PiHole specific one, not fitting into DietPi environment. Pls can you have a look.

ls -la /etc/lighttpd
3

I selected repair because it said I will not loose the configuration on which I spent time.

4

pls can you check lighttpd config files.

ls -la /etc/lighttpd
5

command gives:

I have attached the file. External.conf file is empty.
lighttpd.txt (3.97 KB)

your web server config was replaced by a PiHole one. You would need to revert this change

cd /etc/lighttpd/
mv lighttpd.conf lighttpd.conf.hole
mv lighttpd.conf.orig lighttpd.conf
systemctl restart lighttpd.service
7

Ok I can access NEXTCLOUD web interface, but my PiHole web interface is not working. In services it says pihole-FTL active.
Whats next solution?

8

can you have a look into following directory

ls -la /etc/lighttpd/conf-enabled/

Thank you for your help, but I have to sleep now. I will be back in 14h :slight_smile:.

ok the PiHole config is missing. But this shouldn’t be such an issue. Anyway let’s create it

cd /etc/lighttpd/conf-enabled/
ln -s ../conf-available/99-dietpi-pihole.conf 99-dietpi-pihole.conf
systemctl restart lighttpd.service

I guess it will not fix it. Let’s check web server root directory as well. Probably you are missing the PiHole folders linked correctly

ls -la /var/www/
11

I had an error during restart of service.

root@DietPi:~# cd /etc/lighttpd/conf-enabled/
root@DietPi:/etc/lighttpd/conf-enabled# ln -s …/conf-available/99-dietpi-pihole .conf 99-dietpi-pihole.conf

and now, even after reboot, I cant access web interface for PiHole and for NextCloud too, so nothing is working now.

12

well if your web server is not working, your web apps are not reachable of course. Let’s try to get the web server back before fixing PiHole.

cat /var/log/lighttpd/error.log
13

This command CAT is not showing anything, so I booted LXDE and access the var/log/lighttpd. But error log is empty file. I cannot attached it because attachment on forum says its too large. its 0KB… ???

14

well, it doesn’t make sense to attach an empty file :wink:

let’s check configuration. This will be a test only

/usr/sbin/lighttpd -tt -f /etc/lighttpd/lighttpd.conf
15

root@DietPi:~# /usr/sbin/lighttpd -tt -f /etc/lighttpd/lighttpd.conf

16

your system is quite strange. It’s far away from DietPi standards. Do you install PiHole as well as NextCloud from dietpi-software catalogue?

ls -la /etc/lighttpd/conf-available
ls -la /etc/lighttpd/conf-enabled
17

I found tutorial for installing PiHole with DietPi but with curl command. curl -sSL https://install.pi-hole.net | bash
Everything after that I installed through dietpi.

OK now we know the root cause for all your issues. You should have used dietpi-software to install PiHole. Next time, pls do it that way. that causes less headache.

Let’s try to fix it.

curl -sSfL https://raw.githubusercontent.com/MichaIng/DietPi/master/.conf/dps_93/lighttpd.pihole.conf -o /etc/lighttpd/conf-available/99-dietpi-pihole.conf
cd /var/www
ln -s html/pihole pihole
ln -s html/admin admin
systemctl restart lighttpd.service

if it’s still giving error during web server start, try to test configuration again

/usr/sbin/lighttpd -tt -f /etc/lighttpd/lighttpd.conf
19

Its ok now.

PiHole, NextCloud, UrBackup, MotionEye I can access through IP address.

I am sorry for wasting your time, but I just got THE wrong youtube tutorial video.

So to sum up if I install over official dietpi program all the apps this wont happen.
I am asking so I can make changes for my messed up totorial(for myself).

Really really thank you for helping me, and for not wasting time for reinstallation(it would be my 3rd one).

Yes, pls try using dietpi-software if possible. This will ensure most compatibility between all the apps offered. As well it’s much easier/faster using dietpi-software instead of watching (probably outdated) YouTube tutorial :wink:
