Reverse Proxy

Caddy

/etc/caddy/Caddyfile

artalk.your_domain.com {
  tls /etc/caddy/ssl/cert.pem /etc/caddy/ssl/cert.key

  reverse_proxy http://localhost:23366 {
    header_up X-Forwarded-For {header.X-Forwarded-For}
  }
}

Reload the Caddy configuration:

sudo systemctl reload caddy

Nginx

Assumptions:

• The domain you want to bind is: artalk.your_domain.com
• Artalk local address: http://localhost:23366

For Ubuntu 20.04:

Create the site configuration file:

sudo vim /etc/nginx/sites-available/artalk.your_domain.com

Edit the reverse proxy configuration file:

server {
  listen 80;
  listen [::]:80;

  server_name artalk.your_domain.com;

  location / {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://localhost:23366/;
  }
}

Create a symbolic link to enable the site:

sudo ln -s /etc/nginx/sites-available/artalk.your_domain.com /etc/nginx/sites-enabled/

Check if the configuration file is valid:

sudo nginx -t

If the configuration is correct, restart Nginx:

sudo systemctl restart nginx

Configure the frontend:

Artalk.init({ server: 'http://artalk.your_domain.com' })

TIP

You can also add a layer of CDN and SSL.

Pay attention to the configuration file permissions and the accessibility of the reverse proxy target URL.

Especially if Artalk is running inside a Docker container, make sure the IP and port can be accessed by Nginx.

Apache

You need to enable the reverse proxy module mod_proxy.c

<VirtualHost *:80>
    ServerName your_domain.xxx
    ServerAlias

    RewriteEngine On
    RewriteCond %{QUERY_STRING} transport=polling         [NC]
    RewriteRule /(.*)           http://localhost:23366/$1 [P]

    <IfModule mod_proxy.c>
        ProxyRequests Off
        SSLProxyEngine on
        ProxyPass / http://localhost:23366/
        ProxyPassReverse / http://localhost:23366/
    </IfModule>
</VirtualHost>

BaoTa Panel (宝塔面板)

First, create a site (e.g., artalk.your_domain.com), then click the site "Settings":

Open the "Reverse Proxy" tab, click "Add Reverse Proxy", fill in the "Target URL" with http://localhost:port (where the port corresponds to the Artalk port), and fill in the "Send Domain" with $host, as shown in the figure:

Getting the Accurate IP Address

When using a reverse proxy server, you need to configure the proxy headers to get the user's accurate IP address. Refer to the IP Region documentation for more details.
