Installation

Nginx terminates SSL/TLS.

/etc/nginx/conf.d/mys-lang.org.conf:

server {
    listen 80 http2;
    server_name mys-lang.org;
    client_max_body_size 50M;
    gzip on;
    gzip_types image/svg+xml application/javascript application/json text/css text/html;

    location ^~ /.well-known/acme-challenge/ {
        root /var/www/mys-lang.org;
    }

    location / {
        if ($request_method ~* "(GET|POST)") {
          add_header "Access-Control-Allow-Origin"  *;
        }

        if ($request_method = OPTIONS) {
          add_header "Access-Control-Allow-Origin"  *;
          add_header "Access-Control-Allow-Methods" "GET, POST, OPTIONS, HEAD";
          add_header "Access-Control-Allow-Headers" *; #"Authorization, Origin, X-Requested-With, Content-Type, Accept";
          return 200;
        }

        proxy_pass          http://localhost:8000/;
        proxy_http_version  1.1;
        proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
    }
}

Install certbot.

https://www.nginx.com/blog/using-free-ssltls-certificates-from-lets-encrypt-with-nginx/

Create a certificate and automatically updates nginx configuration. Enable redirect of http to https.

sudo certbot --nginx -d mys-lang.org

Run once in a while to renew the certificate.

sudo certbot renew

ZFS storage with compression and deduplication

There are lots of identical files in releases. Dedup saves disk space. So does compression with LZ4. Not sure about the combination of the two.

$ sudo dd if=/dev/zero of=/home/mys/database.img bs=4096 count=262144
$ sudo zpool create mys-website /home/mys/database.img
$ sudo zpool set autoexpand=on mys-website
$ sudo zfs create mys-website/database
$ sudo zfs set compression=lz4 mys-website/database
$ sudo zfs set dedup=on mys-website/database
$ sudo zfs set mountpoint=/home/mys/database mys-website/database
$ zpool list
