omv_pihole.md

OMV (/etc/nginx/sites-enabled/openmediavault-webgui):

OMV default configuration is consuming all /**/*.php requests. We've to exclude /pihole php requests to forward them to pihole.

location ~ ^(?!\/pihole\/).*\.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/run/php/php7.3-fpm-openmediavault-webgui.sock;
    fastcgi_index index.php;
    fastcgi_read_timeout 60s;
    include fastcgi.conf;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

pihole proxy pass (/etc/nginx/sites-custom/pihole.conf)

location /pihole/ {
	proxy_pass http://127.0.0.1:8080/admin/;
	proxy_set_header Host $host;
	proxy_set_header X-Real-IP $remote_addr;
