Nginx configuration

Assuming you configured the app to run on port 3000.

Configuration file

Create a nginx configuration file:

sudo nano /etc/nginx/conf.d/metahkg.conf

In the following examples, replace the domains

• example.com -> you main metahkg domain / subdomain
• i.example.com -> you domain / subdomain for the image proxy
• l.example.com -> you domain / subdomain for the link shortening server
• rlp.example.com -> you domain / subdomain for the link preview proxy

Self signed certificate, or you already have a certificate

server {
    server_name example.com l.example.com i.example.com rlp.example.com r.example.com;
    # replace with your domains

    server_tokens off;

    listen 443 ssl;
    listen [::]:443 ssl;

    ssl_certificate /etc/ssl/certs/ssl-cert-snakeoil.pem;
    # replace with your certificate
    ssl_certificate_key /etc/ssl/private/ssl-cert-snakeoil.key;
    # replace with your private key


    location / {
        proxy_set_header Host $host;
        proxy_pass http://localhost:3000;
    }
}
server {
    server_name example.com l.exmaple.com i.example.com rlp.example.com r.example.com;
    # replace with your domain

    server_tokens off;

    listen 80;
    listen [::]:80;

    return 301 https://$host$request_uri;
}

Use Let's encrypt for certificate

server {
    server_name example.com l.example.com i.example.com rlp.example.com r.example.com;
    # replace with your domains

    server_tokens off;

    listen 80;
    listen [::]:80;

    location / {
        proxy_set_header Host $host;
        proxy_pass http://localhost:3000;
    }
}

Reload nginx

sudo systemctl reload nginx

Metahkg is now available at your domain. If you want to use let's encrypt for ssl certificate, follow the steps at letsencrypt.
