Use Nginx load balancing to build high performance. Netweb Application Two

In the article, using Nginx load Balancing to build High-performance. Netweb application One, let's have a preliminary understanding of Nginx, and we'll use the Nginx demo cluster below the Windows platform to deploy our Web applications.

First, download Nginx deployment package

to Nginx website to download a Windows platform under the Nginx deployment package, I currently download a nginx-1.6.2 version of the.

Second, the command to start the service
Start: Start Nginx.exe
Stop: Nginx-s stop

Reload: Nginx-s Reload

Third, the example constructs
First choice: We need to deploy our Web application to the top of our IIS, deploy to different machines, set the corresponding IP and port number, because I simulate the effect on the native, so I have deployed 2 Web applications on the native IIS. The first Web application was deployed on the localhost:8011 port, the second application was deployed as a localhost:8012 port, and in order to see the demo, we made a tag inside the WebForm1.aspx page labeled: Page of the first few Web applications, we actually deploy the system, and we don't have to do that by deploying 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, specific configuration instructions, we set the department description in the parameters, and then verify that the service is starting normally.

(3) Access to address http://localhost:8010/WebForm1.aspx observation results

(4) So we can simulate the load balancing effect, OK

Iv. Other Notes

(1) Configure domain name access: First of all, we want to add the domain name setting in the Nginx, secondly we want to set the 127.0.0.1 map to domain name in the local

So we can access it like this: http://huangxiang:8010/WebForm1.aspx

(2) Configure the number of processes initiated by the Ngnix, we can focus on the process number of changes

Five, parameter setting
