ScenarioBecause the company's intranet has multiple servers whose http services need to be mapped to the company's Internet static IP address, if you use the routing Port ing, you can only map the port 80 of an intranet server to the Internet port 80, port 80 of other servers can only be mapped to non-Port 80 of the Internet. Non-Port 80 ing requires adding ports to the domain name during access, which is troublesome. In addition, the company's entry route can only perform 20 Port in

Nginx is a server software that is also a high-performance HTTP and reverse proxy server, as well as a proxy mail server. In other words, we can publish the website on the Nginx, can realize the load balance (enhances the reply efficiency, avoids the server crashes), but also can realize the function as the mail server to send and receive the mail. And the most c

I. nginx reverse proxy and Server Load balancer
1. What is
Nginx This lightweight, High-performance Web server can mainly do two things:
Directly as HTTP server (instead of Apache, PHP requires fastcgi processor support);
Another function is to implement load balancing as a reverse proxy server
Here's an example of how you can use Nginx to achieve load balancing. Because of Nginx's advantages in dealing with concurrency, this application is now very common. Of co
First, write about the first into the blog park feelingAs we all know, Nginx is a high-performance HTTP and reverse proxy server, in the previous work, either implement HTTP or reverse proxy or load balancing. The same nginx or cluster has not yet implemented both HTTP and reverse
The reverse proxy can be divided into two types in transmission:
1: Synchronous mode (apache-mod_proxy and squid)
2: asynchronous mode (Lighttpd and nginx)
In the nginx documentation, I mentioned the asynchronous transmission mode and mentioned that it can reduce the number of backend connections and pressure. Why?
Next, let's take a look at the differences between synchronous transmission of tradit
