The author of this article (), please respect the author's copyright while reading this article. [Abstract] Linux is a multi-user and multi-task operating system. It implements fair and efficient scheduling for multiple processes, rather than using a single scheduling policy, instead, several scheduling policies are organically integrated. [Keywords] process

Scheduling? I am familiar with it. Do we often hear it. Yes, we have heard of scheduling, such as traffic control scheduling. No, this is hot in summer, and the slogans are well pasted: It's awkward to be a civilized citizen in China's power grid dispatching system! No. If you still don't understand it, let's talk about it again, go home in the new year, and go h

Little Chenbo main 2017-11-30 21:11:56 preface to the Broken language In the stand-alone application period, the task scheduling is generally based on spring schedule and integrated quartz to achieve, when the system developed into distributed services, the application of multiple instances, the task will appear many times the problem, many times our task does not need to run many times. There are many solutions, the simplest and most brutal of which

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 Load balancer, LVS forwards the customer's requirements to the backend to provide services, therefore, backend services are called real servers; LVS is divided into two sections.
