Use Nginx load balancer to build high performance. Netweb Application II

One, download Nginx deployment package

To the Nginx website to download an NGINX deployment package under the Windows platform, I am currently downloading a nginx-1.6.2 version.

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

Reload: Nginx-s Reload

Iii. Construction of examples
Preferred: We are going to deploy our well-done Web application on our IIS, deploy it to different machines, set the corresponding IP and port number, because I am simulating the effect on this machine, so I deployed 2 Web applications on this computer. 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: The pages of the Web application, the actual deployment of the system, we do not need to do this is to deploy one of our Web applications on the server above the 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 Nginx Service

(2) Modify the Nginx configuration, specific configuration instructions, we set the parameters in the department description, and then verify that the service started normally.

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

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

Iv. Other Notes

(1) Configure the domain name access: First we want to add the domain name setting in Nginx, next we want to set the 127.0.0.1 map to the domain name in the native machine

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

(2) Configure the number of processes that Ngnix starts, and we can focus on the number of process changes in the process

Five, parameter setting
