Nginx series ~ Implementation of Server Load balancer and WWW server, nginx Load Balancing
The last two lectures are mainly about the Nginx environment, which does not involve the development of the real environment. In this example, describe how to configure Nginx for the Server Load
and so on, and will return the wrong request back to another node, but the disadvantage is that the URL is not supported to detect. For example, the user is uploading a file, and processing the upload node just in the upload process failure, Nginx will upload to another server to re-processing, and LVS directly broken off, if it is to upload a large file or very important files, users may be dissatisfied.
Nginx is not only a good load
Summary: For a large website, Server Load balancer is an eternal topic. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 big-IP, Citrix NetScaler, and radware, however, the high price is often pro

As you can see, traditional Server Load balancer is only a load balancing technology. Currently, in the face of complex network application requirements, the independent Server
machine. If the real situation is like this, it is understandable to do so. What if the situation is not so? The physical performance and configuration of each slave is not the same, and the use of random load balancing, regardless of performance, is very unscientific, which can bring unnecessary high loads to machines with poor machine performance, even the risk of downtime, while high-performance databas

The current development trend of the website for the use of network load balancing is as the scale of the website increases according to different stages to use different technologies:One is through hardware. Common Hardware includes expensive NetScaler, F5, radware, array, and other commercial load balancers, it has the advantage of a professional maintenance te
one file. The benefits are simple, possibly as long as there are few configurations. However, as the number of servers increases, it becomes very difficult to monitor log files on each server.
2. Logging to a share this method is still available for each server, but they are stored on a central file server through a sharing mechanism, which makes monitoring logs easier. The problem with this scenario is that if the file server is unavailable, a simple log cannot be written to the problem that e

Currently, F5 type dedicated server Load balancer is the most widely used Server Load balancer device in the data center. You may learn more about Server Load balancer by focusing on DN
as the Hot Standby. all requests are distributed to the Master server, switch to the backup server immediately to improve the overall system reliability.

Apache can meet the above two requirements. Let's first discuss how to implement load balancing. First, you need to enable several Apache modules:
Program code
LoadModule proxy_mod
Apache self-built Server Load balancer cluster function recorded by: xuanfei
I have searched the internet and found that it seems that I seldom talk about the functions of the mod_proxy module. So today I am going to learn how to buy it. Let's talk about the versions earlier than apache2.2, I have more information about the internet. I 'd like to say a few simple words below :)

Now, basically all enterprises use the network for daily work. In the network operation of an enterprise, the transmission and data sending and receiving processes are not evenly distributed. Then, using Server Load balancer technology can achieve a balanced concept. So how to implement it? If it is not realistic to purchase large load balancing equipment, softwa
