Use Nginx load balancing to build high-performance .NET web applications 2

In the article "Using Nginx Load Balancing to Build High-Performance .NET Web Applications 1", we have a preliminary understanding of Nginx. Next, we will use the Nginx demonstration cluster to deploy our web application under the windows platform.

1. Download the Nginx deployment package

Go to the Nginx official website to download an Nginx deployment package for the windows platform. Currently, I downloaded an nginx-1.6.2 version.

2. Command to start the service
Start: start nginx.exe
Stop: nginx -s stop

Reload: nginx -s reload

3. Example construction
First choice: We need to deploy our web application on our IIS, deploy it to different machines, and set the corresponding IP and port number. Because I simulate the effect on this machine, I Two web applications are deployed on the iis of this machine. The first web application is deployed on localhost: port 8011, and the second application is deployed on localhost: port 8012. At the same time, in order to see the demonstration effect, we put the WebForm1. The aspx page has a mark, which is marked as: The page of the web application. In fact, when we deploy the system, we don’t need to do this. We just deploy one of our web applications to a server on a different machine, as shown below.

web application 1 address: http://localhost:8011/WebForm1.aspx
web application 2 address: http://localhost:8012/WebForm1.aspx

(1) Start Nginx service

(2) Modify the Nginx configuration items. For specific configuration instructions, we will explain them in the parameter setting department, and then verify whether the service starts normally.

(3) Access addresshttp://localhost:8010/WebForm1.aspxObservation results

(4) In this way we can simulate the load balancing effect, ok

4. Other instructions

(1) Configure domain name access: First we need to add domain name settings in Nginx, and secondly we need to set 127.0.0.1 to be mapped to the domain name on this machine

In this waywe can access it like this: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 during the process

5. Parameter settings
