In network applications, "Server Load balancer" is no longer a new topic. From hardware to software, there are also many ways to achieve Server Load balancer. The server Load balancer discussed here does not refer to Server
Nginx Server Load balancer configuration instance details
First, let's take a brief look at what Server Load balancer is. Simply understanding what it means literally can explain that N servers are equally loaded, A server is not idle because of its high load downtime. The p
The general use of load balancing is to use different technologies depending on the stage of the site's ascent. Specific application needs to be specific analysis, if it is small and medium-sized Web applications, such as the daily PV less than 10 million, with Nginx can be completely; if there are many machines, you can use DNS polling, LVS consumes more machines or more, large web sites or important services, and the server is relatively long, You c

Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load
"I am a novice in load balancing, the documentation is too complex and needs getting started. ”"I want to initialize a load balancer for the first time in life and need guidance. ”If you are a novice, if you first touch the load balancer, if its name is Citrix NetScaler, the
1. When configuring Server Load balancer, you need to install the TCP/IP protocol on each computer or server that needs to implement the Server Load balancer environment, and it is best not to install other protocols on these machines (such: IPX/SPX Protocol) to avoid affecting the
with our solution, and fault-tolerant performance is not a test. Of course, there is always a solution to the problem. We introduce the concept of clustering, which I call the Group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer
Cluster) A cluster is a loosely coupled multi-processor system composed of a group of independent computer systems. It communicates with each other through a network. Applications can transmit messages through the network shared memory to implement distributed computers.Load Balance) Server Load balancer is a dynamic balancing technology. It uses some tools to analyze data packets in real time, master the
There are many Server Load balancer solutions. The haproxy + keepalived solution is used here.
