Under the condition that the price of computer hardware declines and the network topology develops, distributed computer system provides a rich collection of resources for users. When people study distributed systems, they notice a problem: In a multiple-computer environment connected by a network, at a certain point, some computers load more heavily, while others are lighter. Balancing the

the load temporarily Weight: indicates the weight. The higher the weight, the higher the probability of being accessed. Backup: other backup machines are requested when they are down or busy. Max_fails: the default number of failed requests is 1. If the maximum number of failed requests is exceeded, an error defined by the proxy_next_upstream module is returned. Fail_timeout: The pause time after max_fails failed. Iii. Server

server list is not changed.4. Weighted round-robin methodDifferent back-end servers may not have the same machine configuration and current system load, so they have varying compression capabilities. Configure a high, low-load machine with higher weights to handle more requests, and configure low, high-load machines,

The size of the internet increases by one times every 100 days, and customers want to get 7 days and 24 hours of uninterrupted availability and faster system response times, rather than repeatedly seeing a site "ServerToo Busy "and frequent system failures. With the increase of traffic volume and the rapid growth of traffic volume and data flow, the processing capacity and calculation intensity of the network are increased, which makes the single equipment unable to bear. In this case, if you th

1. Cluster 1.1 definition:is a set of independent computer systems that form a loosely coupled multiprocessor system that communicates between processes over a network. Applications can deliver messages over network shared memory for distributed computers.is a group of connected computers, from the outside it is a system, each node can be a different operating system or computer composed of different hardware. A cluster that provides Web services is a large Web server to the outside world. Howev

Configure upstream in Nginx for Load Balancing If Nginx does not have to proxy only one server, then it cannot be as popular as today. Nginx can configure proxy for multiple servers. When one server is down, the system remains available. The specific configuration process is as follows: 1. Add an upstream node under the http node. Upstream linuxidc {Server 10.0.6.108: 7080;Server 10.0.0.85: 8980;} 2. Config

Disclaimer: This article is reproduced.When a server (including Web servers, FTP servers, or streaming media servers, etc.) is put into the network, as the number of clients increases, people often need servers that are more powerful and processing faster. To solve this problem, it is obviously not a good idea to replace the original server with a more powerful, faster server. But if you can add a new server to the processing power of the original server instead of replacing it, this scheme is u
