Nginx is a lightweight Web server / reverse proxy server and email (IMAP/POP3) proxy server, distributed under the BSD-like protocol. It is characterized by less memory and strong concurrency ability. in fact, the concurrency ability of nginx performs better in the same type of web server. Chinese mainland uses nginx website users: Baidu, JD.com, Sina, NetEase, Tencent, Taobao and so on.

Let's demonstrate the process of configuring Nginx

1. Download Nginx package: http://nginx.org/en/download.html Note: the path for downloading and storing Nginx package must be in English; it cannot contain Chinese characters.

two。 Start Nginx: directly to the downloaded Nginx package, double-click to open "nginx.exe", or you can start it through the command; the command startup is not detailed here; after startup, open the task manager, you will find that there will be Nginx services in the task manager

3. At this point, you can use Nginx to configure load balancing. I first start multiple WebApi servers and run them, and the data returned by the same interface of each server is slightly different; the data returned by the interface of the first server is: day and night education-1, the data returned by the interface of the second server is: day-and-night education-2, and the data returned by the interface of the third server is: day-and-night education-3 The ports of the three servers after startup are: 8011 8022 8033; that is to say, port 8011 returns: day and night education-1; port 8022 returns: day-and-day education-3; that is to say, the codes of the three servers are the same, and the results returned here are different in order to be able to test the difference.

4. After startup, the debugging result is:

Http://127.0.0.1:8011/api/First returns: day and night education-1

Http://127.0.0.1:8022/api/First returns: day and night education-2

Http://127.0.0.1:8033/api/First returns: day and night education-3

5. The test shows that all three services have been started: at this point, I will configure the three server bronze drum nginx clusters; configure the configuration file

Modify the configuration file as follows:

CMD executes the nginx-s reload command, reloads the service, and tests as follows:

6. Request the same address: http://127.0.0.1:8080/api/First gets three different results three times
