Many websites do not need a large scale at the beginning, but as a website designer, expansion must be taken into account from the very beginning to build a highly scalable architecture. The so-called scalability means that the system can improve the carrying capacity of the system through scale expansion. After all, the vertical expansion of the server itself will soon be restricted, and the single machine will soon be unable to meet our needs, therefore, this capability is often achieved by ad

distribution strategy, where load balancing typically includes random load balancing and weighted load balancing. Random load balancing It is well understood that a slave is randomly selected from n slave. Such random load balancing does not take into account machine perfor

apache plug-in. Define the workers list structure: Worker. list = For example: Worker. list = worker1, worker2 When apache is started, workers. properties is used as a plug-in to initialize and present workers in the worker. list. 2. define the Workers type: Each named worker should have additional information about it. This information includes the worker type and other related information. The workers type defined in JK1.2.5 is discussed here. Define the worker type pattern: Worker. worker

(taking PHP as an example ), you cannot directly use the $ _ SERVER ['remote _ ADDR '] variable to obtain the real IP address of the user. In this case, the IP address of the Nginx SERVER Load balancer is obtained. In this case, you need to add the Header information X-Forwarded-For in the Nginx reverse proxy so that the backend SERVER can get the user's real IP

request is sent, and then send the request to the server. Client-Based Load Balancing features: Implemented by the internal program of the client, without the need for additional hardware and software investment of the Server Load balancer. The program must solve the problem of Service Server unavailability, And the Server failure has little transparency to t

Ps:nginx/lvs/haproxy is currently the most widely used three load balancing software, I have been implemented in a number of projects, reference to some information, combined with some of their own experience, summed up.The general use of load balancing is to use different technologies depending on the stage of the sit

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. The concept of LVSLVS is the abbreviation for Linux virtual server, which is the

Reverse proxy Load Balancer ApacheOne, reverse proxy1.1 Introduction Reaction AgentThe reverse proxy method refers to a proxy server that accepts connection requests on the Internet, then forwards the request to a server on the internal network and returns the results from the server to the client requesting the connection on the Internet, Reverse. At this point the proxy server appears as a reverse proxy s

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
