How to build Nginx and Tomcat servers under Debian to achieve load balancing

The basic concept of load balancing Load balancing (loadbalancing) is a computer network technology used to distribute load among multiple computers (computer clusters), network connections, CPUs, disk drives or other resources to achieve optimal resource usage. The purpose is to maximize throughput, minimize response time, and avoid overload. Using multiple server components with load balancing instead of a single component can improve reliability through redundancy. Load balancing services are usually performed by specialized software and hardware. One of the most important applications of load balancing is the use of multiple servers to provide a single service. This solution is sometimes called a server farm. Usually, load balancing is mainly used in web websites, large-scale Internet

How to install and configure nginx HTTP server

The http server is relatively slow in processing static resources by tomcat, so the first thing that comes to mind is to put all static resources (js, css, image, swf) into a separate server and use a faster http server. Here I chose nginx, nginx Compared with apache, it is more lightweight and simpler to configure, and nginx is not only a high-performance http server, but also a high-performance reverse proxy server. At present, many large websites use nginx. Sina, NetEase, QQ, etc. all use nginx, which shows that the stability and performance of nginx are still very good. 1.nginx installation (linux) download the latest stable version according to your needs

Set accept_mutex in Nginx to on, which will serialize multiple Nginx processes (workerprocessers) when receiving connections to prevent multiple processes from competing for resources. The default is on. multi_accepton;nginxworkerprocesse

Nginx initialization configuration method

Basic Concept The most common use of nginx is to provide reverse proxy services, so what is a reverse proxy? I believe that many mainland compatriots have used forward proxy in this magical land. The principle is roughly as follows: the proxy server acts as an intermediary on the client side to accept requests, hide the real client, and obtain resources from the server. If the proxy server is outside the Great Wall, it can also help us achieve the purpose of crossing the Great Wall. As the name suggests, a reverse proxy is to use the proxy server as an intermediary for the server, hiding the server that actually provides services. The principle is roughly as follows: This is of course not to achieve the purpose of crossing the Great Wall, but to achieve a series of functions such as security and load balancing. . The so-called security means that the client’s request will not fall directly on the intranet server but

How to use nginx keepalive

The default request header of the http1.1 protocol is to enable keepalive by default, as shown in the figure: So what is keepalive? What is the function? Keepalive is a mechanism in TCP that can detect dead connections. Its function is to keep long socket connections from being disconnected. It is a function of the TCP layer and does not belong to the application layer. How does the tcp layer maintain a long connection? Let’s look at the usage of keepalive first: there are three parameters, open to the application layer: sk->keepalive_probes: the number of detections, the number of retries sk->keepalive_time, the heartbeat interval of the detection, and how many seconds after the tcp link has no data packet transmission to start the detection packet
