nginx certbot certificate www and non-www
I haven't really wrapped my head around how to create (working) certificates using certbot for nginx.
My sites-enables now look like this:
First, a block for the www domain with SSL. All the SSL stuff is created by certbot.
server {
root …
index …
server_name www.doman.com
listen 443 ssl;
ssl_certificate …
ssl_certificate_key …
include …
ssl_dhparam …
}
After this, a redirect from port 80 to port 443 for both www and non-www. The first part – the if statement – is created by certbot and not me.
server {
if ($host = www.example.com {
return 301 https://$host$request_uri;
}
listen *:80;
server_name domain.com www.example.com;
return 301 https://www.example.com$request_uri;
}
And finally, a block for 443 without www. I want this to redirect to www.
server {
listen 443;
server_name www.domain.com
return 301 https://www.example.com$request_uri;
}
This plays out well for the domain with www. However, without www, I get "this site cannot be reached". Even when I try it with http and and not https.
Where am I fucking this up? My guess is that the third block, that used 443 for non-www, needs SSL certificates as well. But I use certbots automatic creation, and it doesn't add any.
I don't allow certbot to create my web server configurations. I frankly don't trust it to get it right, since it's already doing some not very efficient practices.
So I get certs with certbot certonly --webroot -w /var/www -d hostname -d hostname
...
And my nginx configuration looks like this (for one example domain):
server {
server_name www.yes-www.org yes-www.org;
access_log off;
include includes/listen-80;
include includes/cloudflare;
include includes/letsencrypt;
location / {
return 301 https://$host$request_uri;
}
}
For port 80 I'm just serving both hostnames and redirecting to https and www unconditionally.
server {
server_name yes-www.org;
access_log off;
ssl_certificate /etc/letsencrypt/live/www.yes-www.org/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/www.yes-www.org/privkey.pem;
include includes/listen-443;
include includes/cloudflare;
include includes/ssl;
include includes/hsts;
include includes/letsencrypt;
location / {
return 301 https://www.yes-www.org$request_uri;
}
}
For port 443 non-www I'm just redirecting to www unconditionally.
server {
server_name www.yes-www.org;
root /srv/www/yes-www.org;
access_log /var/log/nginx/yes-www.org-access.log nginx;
access_log /var/log/nginx/cache.log cache;
error_log /var/log/nginx/yes-www.org-error.log;
ssl_certificate /etc/letsencrypt/live/www.yes-www.org/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/www.yes-www.org/privkey.pem;
include includes/listen-443;
include includes/cloudflare;
include includes/letsencrypt;
include includes/ssl;
include includes/hsts;
include includes/favicon;
include includes/wordpress;
include includes/php;
include /srv/www/yes-www.org/nginx.conf;
location ~ /\.(ht|git) {
deny all;
}
}
And finally here I'm serving a web site.
Note that the contents of /etc/nginx/includes/letsencrypt
are:
location /.well-known/acme-challenge/ {
root /var/www;
try_files $uri =404;
}
Which makes certbot certonly
as above work.
