Use existing installed DNSMASQ together with pi-hole FTL without interuptions
DNS service is not started during installation
Hi, I'm using my PI as DNS and DHCP server with DNSMASQ, I tried to install pi-hole but it could not start dns service.
Then I learned that it's using own FTL dns. Is there any way to install pi-hole without interupting existing dns / dhcp?
Pi-Hole will perform both of these functions. Your existing dnsmasq configuration files can still be used.
You will need to stop dnsmasq so pihole-FTL can listen on port 53. Then Pi-Hole will work properly. From your debug log, dnsmasq is on port 53.

@jfb Thanks for the tip, could please tell me at which point I need to stop dnsmasq?
Because I get no DNS if I disable it before installation and installation needs dns.
And it during the installation it says:
Stopping DNS service
Starting DNS service -> but this finishes with timeout and DNS service is never started (when I ran install script as user)
Then I ran installation as root, it went through but FTL does not work correctly and when I enter web admin page all graphs are just loading but does not show anything.
here is the log

You will likely need root user privileges to stop dnsmasq:
sudo service dnsmasq stop
sudo service dnsmasq disable
sudo service pihole-FTL restart
This command will completely remove dnsmasq from your system (except for the one included in FTL):
sudo apt-get remove dnsmasq
