round robin load balancing

Method One, Nginx polling shunt to achieve load balancing Prepare for work, 3 servers, or open a virtual machine! I'm just running a virtual machine.IP is: 192.168.1.10 192.168.1.11 192.168.1.12 (Environment installed NGIXN did not do any configuration)3 Server environment Best, I am a VM directly cloned, the environment is absolutely the same! Not the same, I expect to encounter a lot of strange problems,

test by the core developers and users shows that it works well: The request connection is now evenly distributed. There is also a plan to turn the selection algorithm into a configurable or plugin-based approach.If you want to fall back to the previous assignment method, you can set the Cluster.schedulingpolicy:var cluster = require (' cluster '); // Set This before calling and other cluster functions. Cluster.schedulingpolicy = cluster. Sched_none;cluster.fork ();or use the NODE_CLUSTER_SCHED_

solve the session sharing problem, you can use NFS shared session, the session to write MySQL or Memcache methods, when the machine size is larger, the general use of the session is written into the memcache inside. How the backend Web server is configured we do not discuss this here, the backend server may be apache,nginx,tomcat,lighthttp and so on, the front-end does not care what the back end is.First create a new proxy.conf file to make it easier for us to call later (configure multiple cl

Model has a corresponding load balancing strategy for different application requirements. The advantages and disadvantages of the load balancing strategy and its implementation are two key factors: Load balancing algorithm, detec

balancing algorithm, detection mode and ability of network system condition.1. Load Balancing algorithm1) Round robin (Round Robin): Each request from the network is assigned to the internal server in turn, starting from 1 to N and then restarting. This equalization algorit

. Therefore, taking the tolerable launch as the value of the max_conns command can ensure the relative security of the server.Least Time Load Balancing Algorithm In NGINX Plus R6, a new balancing algorithm, Least Time, is added to take the corresponding Time into account, which is equivalent to the extension of Least Connections. This algorithm takes into account

Principles and implementation of six major Web load balancing and six major web Load Balancing First understand the so-called "balancing" It cannot be understood in a narrow sense that the workload assigned to all actual servers is the same, because the

Ten LVS cluster scheduling algorithms and load balancing theory, lvs Load Balancing I. Concept of LVS LVS (Linux Virtual Server): Linux Virtual Server; LVS is a server Load balancer device that does not provide any services. When a user requests a Server

B's default page is: The Server is website192.168.1.249: 8080. The actual content of The default page of Server C is: The Server is web2_192.168.1.249: 8090. As follows: By default, nginx Server Load balancer uses the round robin Method for allocation. The default weight is 1, and the higher the weight, the higher the chance of being accessed. Configure nginx of server A as follows: Cat/usr/local/ngin

Server Load balancer is a server set composed of multiple servers in a symmetric manner. Each server is equivalent and can provide services independently without the assistance of other servers. Through a load balancing technology, requests sent from outside are evenly distributed to a server in the symmetric structure, and the server receiving the requests indep

we are talking about Load balancer, sometimes called a four-tier load balancer or seven-tier load balancing device, sometimes called a four-layer switch or seven-layer exchange. The four-layer load balancing device mainly analyzes
