How to optimize the Linux kernel of high-concurrency nginx server

How to optimize the Linux kernel of high-concurrency nginx server

The code is as follows: #controlstheuseoftcpsyncookies# means turning on reuse. Allow time-waitsockets to be reused for new TCP connections. The default is 0, which means closed; net.ipv4.tcp_syncookies=1 #A Boolean flag that controls the behavior of the kernel when there are many connection requests. If enabled, the kernel will proactively send rst packets if the service is overloaded. net.ipv4.tcp_abort_on_overflow=1#Indicates that the system maintains the maximum number of time_wait at the same time. If this number is exceeded, time_wait will be cleared immediately and a warning message will be printed.

How to implement Nginx request compression

How to implement Nginx request compression

1. Introduction to request compression, which compresses the server's results through Nginx and then sends them to the client to reduce network transmission pressure and improve transmission efficiency. The two common request methods are: gzip and brotli (Google). The efficiency of brotli is higher, which will be explained in detail later. Requesting compression is divided into: dynamic compression and static compression. Dynamic compression will cause the sendfile inside Nginx to fail. For some unchanged content, static compression can be used to improve request efficiency. For compression of request results, both the client and the server need to support the compression protocol. The server compresses the results and the client decompresses the data. The compression will occupy some performance efficiency on the server side. This

How to use nginx simulation for canary publishing

How to use nginx simulation for canary publishing

Canary release/grayscale release The focus of canary release is: trial and error. The origin of the canary release itself is a tragic story of the beautiful creatures of nature in the development of human industry. The canary uses its life to try and make mistakes for the safety of the miners. A small cost is used to exchange for overall security. In the practice of continuous deployment, the canary is traffic control. A very small amount of traffic, such as one percent or one tenth, is used to verify whether a certain version is normal. If it is abnormal, its function will be achieved at the lowest cost and the risk will be reduced. If it is normal, you can gradually increase the weight until it reaches 100%, and switch all traffic to the new version smoothly. Grayscale publishing is generally a similar concept. Gray is a transition between black and white.

How Nginx merges request connections and accelerates website access

How Nginx merges request connections and accelerates website access

Little knowledge: When we browse the web, there is an important factor that affects the browsing speed, which is the number of concurrent browsers. In simple terms, the number of concurrency refers to the number of simultaneous tasks when browsing a web page. Of course, the browser's limit on the number of concurrent requests is for the same domain name. There is a certain limit on the number of requests under the same domain name at the same time. Requests that exceed the limit will be blocked. First, let’s take a look at the number of concurrent connections of each browser: Let’s list what considerations the browser may have in making this decision. Due to limitations of the TCP protocol, the PC side only has 65536 ports available for sending connections to the outside, and the operating system also has half-open connections. Limit to protect the operating system's tcpip protocol stack resources from being quickly exhausted, so the browser does not

How Nginx solves the problem of WebApi cross-domain secondary requests and Vue single page

How Nginx solves the problem of WebApi cross-domain secondary requests and Vue single page

1. Introduction Since the project is separated from the front and back ends, the api interface and the web front end are deployed in different sites, so in the previous article, the webapiajax cross-domain request solution (cors implementation) uses cross-domain processing instead of jsonp. But after a period of time, I discovered a very strange problem. Every time the front end initiates a request, through the browser's developer tools, I can see that there are two requests for the same URL under the network. The method of the first request is options, the method of the second request is the real get or post, and the first request returns no data, and the second request returns normal data. 2. Reason for the first options
