Hello kids, I'm a big sister who loves to share her knowledge. In today's post, I'm going to explore the Nginx Directory Reverse Proxy Configuration Guide with you. Doesn't it feel very advanced? But don't worry, we have to work together, believe me, if you listen carefully, you can easily master this skill. Without further ado, let's get right into it!

I. What is Nginx?

To learn about Nginx Directory Reverse Proxy, first we need to understand what Nginx is all about. Nginx is a bit of an all-rounder, it is a high-performance open source web server software. Its name is pronounced "engine x", a little cool feeling is not it?Nginx with its high performance, high concurrency features, is widely used in building reverse proxy servers, load balancers and HTTP caching and other scenarios. For developers who are looking for speed and efficiency, Nginx is the absolute first choice!

Second, the concept of directory reverse proxy

Directory Reverse Proxy, sounds a bit lofty, but it's actually not that complicated. It refers to proxying a client's request through the Nginx server to a specified directory on the target server. That is, when a user accesses a directory on the Nginx server, Nginx forwards the request to the corresponding directory on the target server. In this way, the user feels as if they are accessing the target server directly, but in fact there is a "bridge" in the middle. Think about it, isn't it a bit like playing hide and seek?

Third, the configuration of the Nginx directory reverse proxy

Okay, now let's see how to configure Nginx directory reverse proxy. First of all, we have to install the Nginx software on the Nginx server, which is like equipping our big warrior with weapons and armor. Once installed, we open the Nginx configuration file, which is usually located at `/etc/nginx/nginx.conf`. Find the `http` configuration block and add the following code to it:

server {
listen 80; server_name yourdomain.com; server_name yourdomain.com
server_name yourdomain.com;

location /yourdirectory/ {
proxy_pass http://targetserver.com/targetdirectory/; }
}
}

This configuration means that when a user accesses `http://yourdomain.com/yourdirectory/`, Nginx will proxy the request to the directory `http://targetserver.com/targetdirectory/`. Isn't it quite simple?

IV. More Configuration Options for Nginx Directory Reverse Proxy

In addition to the basic configuration, Nginx also provides some optional configuration options to make our proxy more flexible and diverse. For example, we can configure caching, set proxy timeouts, modify request headers, and more. Here is an example:

location /yourdirectory/ {
proxy_pass http://targetserver.com/targetdirectory/;
proxy_cache_bypass $http_upgrade; proxy_set_header Upgrade $http_upgrade; proxy_cache_bypass
proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_cache_bypass
proxy_set_header Connection 'upgrade'; proxy_set_header Connection 'Upgrade'.

}

In this configuration, we use `proxy_cache_bypass` to set the caching policy and `proxy_set_header` to modify the request header. By configuring these options wisely, we can make the proxy more efficient and stable!

Today, we have learned the configuration guide for Nginx Directory Reverse Proxy. By using Nginx, we can achieve efficient directory reverse proxy with simple configuration. Isn't it cool that using Nginx as a proxy not only improves performance, but also makes our system architecture more flexible and scalable?
