This article mainly introduces the related functions of Nginx Plus, which spans the various versions of Nginx plus R5/R6/R7/R9. The more advanced usage of Nginx reverse proxy and load balancing is involved. Mainly include: HTTP load balancer, HTTP long connection, TCP and UDP load
port.Download Nginx's address is as follows:Nginx Download:http://nginx.net/Download of the version used in this test:nginx/windows-0.8.22
Download extract to C:, change directory name to Nginx
OK, here goes the practice:
First:
In the local (172.10.1.97) server, IIS creates a Web site using a port of 808, as shown below:

Second:

F5 Load Balancing PrincipleI. Server Load balancer Technology
The server Load balancer technology provides a cheap, effective, and transparent method based on the existing network structure, to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and im
step 5th and the COM + component in step 1th).
Deploy the application to a WEB-tier cluster.
Ensure that the Web-tier routing list is established and the COM + component is marked to support load balancing.
Run Default.asp from the client. If you do not work at first, you may be the result of the restart of the IIS Service during component deployment. Please
What is load balancing?When the performance of a single server reaches its limit, we can use a server cluster to improve the overall performance of the site. Then, in the server cluster, you need a server to act as the dispatcher's role, all of the user's requests will be first received by it, the dispatcher then according to the load situation of each server to
ASP. NET site for load balancing:based on the HTTP protocol we may find that we have two points to solve:the first is load balancing, we need a load balancer. it can be done by DNS polling, which is configured on the DNS server to obtain a different IP address each time the DNS query for the same host name that we
With the development of information construction in various industries, people put forward higher requirements for the processing ability and high availability of the network server. Especially in highly information-based enterprises, the key network services have become an important part of enterprise generation process, interruption of service means the interruption of production and the loss of opportunity.

2.2Apache load-balanced configuration, because this 2.2.11 and 2.2.8 version integrates JK2 and other load balancing tools, the configuration is a lot simpler 。 Other version I have no specific test, waiting to be refined 。 These two software can be downloaded to the official website 。To install Apache as a Windows service running on port 80, the Apache2.2 servi
different sessionid, on the same Tomcat is also a gap between the SessionID.A more personal experience is to be sure to configure it yourself and carefully observe the output of the two Tomcat controls. Because this article is a reference to the easy implementation of APACHE,TOMCAT cluster and load balancing practice experience, there are more stickers in this book.

The company last year on the F5, easy to use is good, but the cost is too high, so recently has been studying the soft load balancing this together, it happened early this year Google Open source seesaw, let oneself can bypass many detours. This is a summary of the load balancing policies that you learned before. -sunf
following point in time:1, non-running normal processes become real-time processes (such as through the Sched_setscheduler system call);2, after the dispatch (there may be a real-time process is preempted by higher priority real-time processes);3, the real-time process is awakened, if not immediately run on the current CPU (it is not the current CPU on the highest priority process);It seems that the load balancin
, because the nginx software must use port 80.The nginx download address is as follows:Nginx download: http://nginx.net/Download the version used in this test: nginx/Windows-0.8.22
Download and decompress the package to C:, and change the directory name to nginx.
Well, let's go to practice:
First:
On the local server (172.10.1.97), create a website using the port 808, for example:

Second:

mainly implements the following tasks: solving network congestion problems, providing nearby services to achieve geographic location independence, providing users with better access quality, and improving server response speed; this improves the utilization efficiency of servers and other resources, and avoids spof in key parts of the network. In fact, Server Load balancer is not a traditional "Server Load

Both the load server and the Web server are the IP of the public network.This kind of

Apache uses a apache_2.2.11-win32-x86-no_ssl.msi. If versions earlier than 2.2Apache Server Load balancer are configured differently, because 2.2.11 and 2.2.8 are integrated with load balancing tools such as jk2, therefore, the configuration is much simpler. I have no specific tests for other versions and need to learn more. These two software can be d
