I use nginx for my DNS over HTTPS and DNS over TLS. Here is my nginx.conf:
user www-data;
worker_processes auto;
pid /run/nginx.pid;
load_module /etc/nginx/modules/ngx_http_js_module.so;
load_module /etc/nginx/modules/ngx_stream_js_module.so;
events {
worker_connections 768;
}
# DNS Stream Services
stream {
# Import the NJS module
js_import /etc/nginx/njs.d/dns/dns.js;
# The $dns_qname variable can be populated by preread calls, and can
be used for DNS routing
js_set $dns_qname dns.get_qname;
# DNS upstream pool.
upstream dns {
zone dns 64k;
server 127.0.0.1:53;
}
# DNS(TCP) and DNS over TLS (DoT) Server
# Terminate DoT and DNS TCP, and proxy onto standard DNS
server {
listen 853 ssl;
ssl_certificate_key /etc/letsencrypt/live/revvy.de/privkey.pem;
ssl_certificate /etc/letsencrypt/live/revvy.de/fullchain.pem;
js_preread dns.preread_dns_request;
proxy_pass dns;
}
# DNS over HTTPS (gateway) Service
# Upstream can be either DNS(TCP) or DoT. If upstream is DNS,
proxy_ssl should be off.
server {
listen 127.0.0.1:8053;
js_filter dns.filter_doh_request;
proxy_pass dns;
}
}
http {
sendfile on;
tcp_nopush on;
types_hash_max_size 2048;
variables_hash_max_size 2048;
server_names_hash_bucket_size 256;
include /etc/nginx/snippets/mime.types;
default_type application/octet-stream;
log_format main '[$time_local] $host $status $bytes_sent $uri';
fastcgi_read_timeout 300;
proxy_read_timeout 1d;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;
#access_log /etc/nginx/logs/access.log main;
#access_log /etc/nginx/logs/access.log;
access_log /dev/null;

#error_log /etc/nginx/logs/error.log;

resolver 1.1.1.1;
include /etc/nginx/conf.d/*;
}
When I restart the systemd service, I am greeted with:
Sep 17 13:36:52 toronto-srv-03 systemd[1]: Starting nginx.service -
