Use Nginx server load balancer to build high-performance. NETweb application 2

: This article describes how to use Nginx server load balancer to build a high-performance. NETweb application 2. if you are interested in PHP tutorials, refer to it. In this article, we use Nginx server load balancer to build high performance. in NETweb Application 1, we have a preliminary understanding of Nginx. next we will deploy our web application in the Nginx demonstration cluster on the windows platform.

1. download the Nginx deployment package

To Nginx official website to download a windows platform below the Nginx deployment package, I download is a nginx-1.6.2 version.

II. command to start the service
Start: start nginx.exe
Stop: nginx-s stop

Reload: nginx-s reload

III. instance construction
First choice: we need to deploy our web applications on our iis, deploy them on different machines, and set the corresponding ip address and port number, because I simulated the results on the local machine, I deployed two web applications on the local iis, and the first web application was deployed on the localhost: 8011 port, the second application is deployed on the localhost: Port 8012. in order to see the demonstration result, we marked the WebForm1.aspx page as the page of the web applications, in practice, we do not need to deploy the system. we deploy one of our web applications to servers on different machines, as shown below.

Web Application 1 Address: http: // localhost: 8011/WebForm1.aspx
Web Application 2 Address: http: // localhost: 8012/WebForm1.aspx

(1) start the Nginx service

(2) modify the Nginx configuration item. for detailed configuration instructions, describe the parameter setting department and verify whether the service is started properly.

(3) http: // localhost: 8010/WebForm1.aspx

(4) in this way, we can simulate the load balancing effect. OK

IV. other instructions

(1) configure domain name access: first, we need to add domain name settings in Nginx, and then we need to set 127.0.0.1 ING to domain name on the local machine

In this way, we can access: http: // huangxiang: 8010/WebForm1.aspx.

(2) configure the number of processes started by Ngnix. we can pay attention to the changes in the number of processes in the process.

V. parameter settings
