I write this blog post as I spent too much time setting up nginx and
SSL on OpenBSD with acme-client, due to nginx being chrooted and not
stripping path and not doing it easily.
First, you need to set up **/etc/acme-client.conf** correctly. Here is
mine for the domain ports.perso.pw:
authority letsencrypt {
api url "https://acme-v02.api.letsencrypt.org/directory"
account key "/etc/acme/letsencrypt-privkey.pem"
}
domain ports.perso.pw {
domain key "/etc/ssl/private/ports.key"
domain full chain certificate "/etc/ssl/ports.fullchain.pem"
sign with letsencrypt
}
because of Let's encrypt API URL. If you are running 6.5 or 6.4,
replace v02 by v01 in the api url**
Then, you have to configure nginx this way, the most important part in
the following configuration file is the location block handling
acme-challenge request. Remember that nginx is in chroot /var/www so
the path to acme directory is `acme`.
http {
include mime.types;
default_type application/octet-stream;
index index.html index.htm;
keepalive_timeout 65;
server_tokens off;
upstream backendurl {
server unix:tmp/plackup.sock;
}
server {
listen 80;
server_name ports.perso.pw;
access_log logs/access.log;
error_log logs/error.log info;
root /htdocs/;
location /.well-known/acme-challenge/ {
rewrite ^/.well-known/acme-challenge/(.*) /$1 break;
root /acme;
}
location / {
return 301 https://$server_name$request_uri;
}
}
server {
listen 443 ssl;
server_name ports.perso.pw;
access_log logs/access.log;
error_log logs_error.log info;
root /htdocs/;
ssl_certificate /etc/ssl/ports.fullchain.pem;
ssl_certificate_key /etc/ssl/private/ports.key;
ssl_protocols TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";
[... stuff removed ...]
}
}
That's all! I wish I could have find that on the Internet so I share
it here.
