How to use Nginx Proxy Manager to build an efficient reverse proxy server

With the development of the Internet, more and more network applications require reverse proxy servers. Provide services. Nginx Proxy Manager is a powerful and easy-to-use tool that can help us quickly set up and manage a reverse proxy server. This article will introduce how to use Nginx Proxy Manager to build an efficient reverse proxy server and give specific code examples.

1. Install Nginx Proxy Manager

First, we need to install Nginx Proxy Manager on the server. You can use the following command to install:

# 安装Node.js
curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt-get install -y nodejs

# 克隆Nginx Proxy Manager的代码库
git clone https://github.com/jc21/nginx-proxy-manager.git

# 进入代码库目录
cd nginx-proxy-manager

# 安装依赖
npm ci

# 运行Nginx Proxy Manager
npm start

After successfully installing Nginx Proxy Manager, you can enter the management interface by accessing the server's IP address plus the default port 8888.

2. Add domain name and SSL certificate

In the management interface of Nginx Proxy Manager, click "Proxy Hosts" on the left, and then click the "Add Proxy Host" button in the upper right corner to start Add a new proxy host.

In the pop-up dialog box, fill in the "Subdomain" and "Domain" fields. This is the domain name you want to proxy. At the same time, select an already configured SSL certificate.

3. Configure proxy rules

After adding the proxy host, we need to configure proxy rules for the domain name. Click on the proxy host just added, and then click on the "Proxy Rules" tab to start configuring proxy rules.

Click the "Add Proxy Rule" button in the upper right corner and fill in the "Source URL" field and the "Destination URL" field. The "Source URL" is the URL requested by the client, and the "Destination URL" is the URL to which the reverse proxy server forwards the request. For example, if we want to forward all requests starting with /api to http://localhost:3000, we can fill in /api as "Source URL ", http://localhost:3000 is the "Destination URL".

4. Apply the configuration and start the proxy server

After completing the configuration of the proxy rules, click the "Save" button in the upper right corner to save the configuration. Then, click the "Apply Config" button in the upper right corner to apply the configuration.

After the configuration is successfully applied, you can access the reverse proxy server by accessing the server's IP address and the previously configured domain name.

5. Code Example

The following is a sample code for using Nginx Proxy Manager to build an efficient reverse proxy server:

const http = require('http');

// 创建一个http服务器
const server = http.createServer((req, res) => {
  // 在这里处理业务逻辑
  res.end('Hello, World!');
});

// 监听端口
server.listen(3000, () => {
  console.log('Server started on port 3000');
});

6. Summary

Passed Nginx Proxy Manager, we can quickly build and manage efficient reverse proxy servers. You only need to simply configure the proxy host and proxy rules to configure different reverse proxy rules for different domain names or paths. At the same time, Nginx Proxy Manager also provides a variety of functions, such as SSL certificate management and HTTP request logging.
