Install and configure Nginx reverse proxy server in Arch Linux

In Arch Linux, you can configure Nginx as a reverse proxy by following these steps:

1. Install Nginx:

sudo pacman -S nginx

2. Start and enable the Nginx service:

sudo systemctl start nginx
sudo systemctl enable nginx

3. Create a new configuration file for your reverse proxy in the /etc/nginx/conf.d/ directory. For example, if you want to reverse proxy requests to a Golang application running on localhost:8000, you can create a file called golang.conf with the following contents:

server {
    listen 80;
    server_name example.com;
    location / {
        proxy_pass http://localhost:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

• This configuration tells Nginx to listen on port 80 and to forward incoming requests to the Golang application running on localhost:8000. The proxy_set_header lines are used to pass the host, real IP, and forwarded IP to the golang application.

4. Test the configuration by running:

sudo nginx -t

5. If the configuration is valid, reload Nginx to apply the changes:

sudo systemctl reload nginx

• Note that, in this example, we assume that you have a golang application running on localhost:8000, you need to make sure that the golang application is running and configured to handle the incoming request.
• Also, please note that this is just a basic example and should not be used in production without proper testing and security measures. It is always recommended to have a firewall enabled and to have a valid SSL certificate for your domain.
