Nginx (LNMP) Reverse Proxy Configuration Tutorial

When it comes to how to configure Nginx Reverse proxy First, let's understand what is reverse proxy. Reverse proxy is a proxy server that accepts Internet connection requests, and then forwards the requests to another server.

Originally, I could not use the reverse proxy for a long time, so I never did. It happened that a space on EWSIDC a few days ago was not allowed to be bound because of the problem of the domain name (imzhaorong. com) BA, and could only be accessed through the three-level domain name provided by the system. But I still want to use the original top-level domain name to access the content of this space. What should I do? Use the VPS in hand to do reverse proxy. Next, let's look at the detailed process.

First, let's talk about the general environment. The non BA top-level domain name I use is imzhaorong.com, the EWSIDC level 3 domain name is 1e01f.wi.ipc.la, and the VPS I use is the $1 cloud VPS of Host1Plus, and LNMP has been installed.

First, we need to record the domain name imzhaorong.com resolution A to the VPS IP address;

Then, modify nginx Configuration file. In this tutorial, we will download the nginx. conf of VPS to local modification (the file directory is located in/usr/local/nginx/conf/). Let me start with the last screenshot:

The blue part in the figure is the code we added. The reason why we need to add a picture is to pay attention to the location of the code. Zhao Rong had made a mistake before. Fortunately, the fourth senior brother mentioned something. Now, I will paste the code:

server    {
        listen          80;
        server_name     imzhaorong.com;

        location / {
            proxy_pass              http://1e01f.wi.ipc.la/ ;
            proxy_redirect          off;
            proxy_set_header        X-Real-IP       $remote_addr;
            proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
            }
    }

After modification, we first execute:/usr/local/nginx/sbin/nginx - t to check whether the configuration is normal. If it displays: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok      configuration file /usr/local/nginx/conf/nginx.conf test is successful Otherwise, modify the configuration according to the error prompt, and the error prompt will be accurate to which line.

Finally, execute kill HUP ` cat/usr/local/nginx/logs/nginx. pid ` to make the configuration take effect. If your domain name resolution also takes effect, you should be able to access it directly through the top-level domain name.

There are many uses of reverse proxy. Let's explore them by ourselves.
