Servers to provide services externally, when a server under too much pressure, then the service may be caused by the service is not available, so we should let a server under the pressure of reasonable scope, if a server can not meet the requirements, then scale out using multiple servers to apportion these pressures, These servers serve as a whole and distribute the pressure, then we can call these servers "load Balancer cluster".LVS is the abbreviat

One, Introduction LVS (Linux virtual Server) is a virtual server in the Unix-like system and is one of the best projects in China to contribute to open source organization. LVS in the Unix-like system is as a front-end (Director) exists, also known as the scheduler, which itself does not provide any services, but will be sent through the Intern

. Instead of executing the LVS script we configured above, because Ldirectord will automatically call Ipvsadm to create the LVS routing table, we have described above using the IPVSADM command line to configure LVS in order to give readers a deeper understanding of IPVSADM implementation details and implementation mechanisms.If you are configuring

Defined:LVS is a shorthand for Linux virtual server, that is, a virtualized server cluster system.Structure:In general, the LVS cluster uses a three-tier structure, the main component of which is: A, Load Scheduler (load balancer), it is the entire cluster to the outside of the front-end machine, responsible for sending the customer's request to a set of servers to execute,　　And the customer thinks the serv

When it comes to the Web cluster, we can't help but say that LVs is a very good open source software for load cluster, compared with some hardware load, LVS has many excellent performance, such as cheap, stable, support high concurrency scenarios in most cases, below to tell you about the origin of LVS and basic introductionI.

This paper introduces the cluster software LVS under Linux, and gives an example of the detailed process of installation and implementation of cluster (cluster) under Linux.In a variety of network services widely used today, with the speed of the network and increase the number of users, in some busy occasions, a single machine can not be able to cope with all the network requests. To solve this problem, ma
