Engineers from the Nginx company introduced what Ngnix, how to install Nginx and nginx+, the main configuration files, commands and folders, also talked about the basic configuration and Advanced configuration options, including a large number of configuration options and related principles introduced, can be used as a reference to the site operators to get started, Finally, the log and monitoring file management are also discussed.Too long, the original link https://www.slidestalk.com/s/nginx_b

operation Partial Bloom Filter: The value of the hash function of the original Bloom filter is 0~m-1, that is, the subscript range of the entire bit array, whereas in PBF each hash function has a smaller range, with no overlap between the bits, and the bit array is divided into K regions, each hash function value is responsible for a region. The advantage is that the accuracy rate is higher than the original, and the array can be accessed in parallel, optimizing program performance

The React component lifecycle would allow you to update the your components at runtime. This lesson would explore how to does that.Import React from 'react'; import Reactdom from 'React-dom'; exportdefault classApp extends React.component {constructor () {super (); This. State ={increasing:false}} update () {Reactdom.render ( This. props.val+1}/>, document.getElementById ('app')); } componentwillreceiveprops (nextprops) {//invoked when a component is receiving new props. This method isn't calle

React components has a lifecycle, and you is able to access specific phases of that lifecycle. This lesson would introduce mounting and unmounting of your React components.Import React from 'react'; import Reactdom from 'React-dom'; exportdefault classApp extends React.component {constructor () {super (); This. State ={val:0}} update () { This. SetState ({val: This. State.val +1})} componentwillmount () {Console.log ("Component would Mount"); } render () {Console.log ("Rendering"); return (

-oriented class is a well-encapsulated module in which the class definition explicitly separates its description (the user-visible external interface) from the implementation (an internal implementation that is not visible to the user), and its internal implementation provides protection according to the scope it specifically defines. The object is the most basic unit of encapsulation. Encapsulation prevents the change effect of program interdependencies.Object-oriented encapsulation is clearer

other, improving efficiency. However, a highly available cluster can only be started on a single host at a time.brain fissure: because of cluster division, when a node in a cluster cluster temporarily stops responding because of a processor busy or other reason, the other node may mistakenly consider the node "dead", thereby seizing access to the shared disk (that is, the resource). At this point it is very likely that the suspended animation node re-writes to the shared file system, causing th

In the past seven days, I have learned the basis of computer applications, although I think that there is a certain basis for computers, but after the seven days of learning, only to find that they understand is really fur, also in this seven days learned a lot of knowledge.The first is to learn the field of computer, history and its components and operating system, although before some understanding, but the specific characters have time and so not very understanding, but also in the face of le

"UML Foundation and Application Case" This book read half, remember very few things, feel the book a bit redundant, but because want to know about UML (Unified Modeling Language, Unified Modeling Language) The most basic knowledge, so still have to look at it again, The catalogue is listed with mind mapping software.So far, the brain is still mess, there are too many types of graphs, there are many relationships, there is no better way to remember them. Specifically under a STARUML software, to

subclass can have only one base class, and to implement multiple inheritance, it can be implemented by multilevel inheritance.Inheritance concepts are implemented in three categories: implementation inheritance, interface inheritance, and visual inheritance.Implementation of inheritance refers to the ability to use the properties and methods of the base class without additional coding;Interface inheritance refers to the ability to use only the names of properties and methods, but subclasses mus
