Foreign vps reverse proxy to domestic vps: detailed setup guide sharing

Foreign VPS reverse proxy to domestic VPS setup guide

In some cases, you may need to reverse proxy traffic to a domestic VPS via a foreign VPS (Virtual Private Server).This setup can help you achieve better access control, traffic management. In this article, we will introduce the steps of how to configure foreign VPS reverse proxy to domestic VPS in detail.

preliminary

Before you start the configuration, you need to make sure of the following:

• VPS Preparation:Have a foreign VPS and a domestic VPS and make sure they both have normal access to the Internet.
• SSH access:Make sure you can access both VPSes via SSH.
• Install the necessary software:Make sure that reverse proxy software such as Nginx or Apache is installed on both VPSs.

Configuring services on a domestic VPS

First, you need to configure a service (e.g. web application or API) on your domestic VPS so that the foreign VPS can forward requests to it.

1. Log in to your domestic VPS and make sure the service is up and running. For example, for a simple HTTP service, you can use Nginx or Apache.
2. Verify that the service's port (e.g. 80 or 8080) is open and able to accept requests from the foreign VPS.
3. To test if the service is working properly, you can access the IP address or domain name of the domestic VPS in your browser.

Configuring a Reverse Proxy on a Foreign VPS

Next, you need to configure a reverse proxy on the foreign VPS to forward requests to the domestic VPS.

1. Install Nginx

If you choose to use Nginx as a reverse proxy, please make sure that Nginx is installed on the foreign VPS. you can use the following command to install it:

# For Debian/Ubuntu systems
sudo apt update
sudo apt install nginx

# for CentOS
sudo yum install epel-release
sudo yum install nginx

2. Configure Nginx reverse proxy

Open the Nginx configuration file, usually located at `/etc/nginx/sites-available/default` or `/etc/nginx/nginx.conf`, and add the following:

server {
listen 80; # listen on port
server_name yourdomain.com; # Replace with your domain name or IP address.

location / {
proxy_pass http://国内VPS的IP地址:服务端口; # Replace with the IP and port of your domestic VPS
proxy_set_header Host $host; proxy_set_header X-Resource_Port; # Replace with your domain name or IP address.
proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Real-IP $remote_addr
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for
proxy_set_header X-Forwarded-Proto $scheme;
}
}

3. Test configuration

After completing the configuration, use the following command to test the correctness of the Nginx configuration:

sudo nginx -t

If there are no errors, restart Nginx for the configuration to take effect:

sudo nginx -t

Security settings

In a production environment, you may want to consider the following points in order to ensure security:

• Firewall Configuration:Make sure that the firewall of the domestic VPS allows requests from foreign VPS. This can be configured using `iptables` or `firewalld`.
• SSL encryption:Consider configuring an SSL certificate for Nginx to ensure secure data transfer. You can use a free certificate provided by Let's Encrypt.
• Access Control:Restrict which IPs can access the domestic VPS to improve security.

Testing and validation

After completing all the settings, you can test if the reverse proxy is working properly by accessing the IP address or domain name of the foreign VPS. If configured correctly, you should be able to access the services running on your domestic VPS.

summarize

With the above steps, you can successfully configure a reverse proxy on a foreign VPS to forward traffic to a domestic VPS. this configuration not only improves access speed, but also enhances security to a certain extent. In practice, reasonable configuration and management of reverse proxy will provide you with greater flexibility and control.
