Load Balancing can allocate the user's request to multiple servers for processing, thus realizing the access support to the massive users. The load-balanced architecture is shown in the figure: For complex web applications, it's a matter of course to use Nginx to do front-end load balancing.Below, we use Nginx to do nodejs application load balancing.1. Configure NginxModify nginx.conf: Upstream Sample { server 127.0.0.1:3000; Se

Please read this sentence carefully if the parent class has a private property. Then the parent class's method is only a private property service for the parent class. Here's a list of the following to deepen your understanding. This example looks strange, redefining an attribute $sal in a subclass, and the system returns the properties of the parent class. Copy CodeThe code is as follows: Class employee{ Private $sal = 3000; protected $sal =

various coordinate systems. Here we will first provide a basic knowledge. The coordinate systems mentioned below are the horizontal right of the X axis and the vertical downward of the Y axis. AlphaAnimation AlphaAnimation allows the View to achieve a gradient of transparency. The usage is as follows: // 1.0 indicates full opacity, and 0.0 indicates full transparency float fromAlpha = 1.0f; float toAlpha = 0.0f; // 1.0 => 0.0 indicates that the View changes from completely opaque to completely

First, this question is a bit problematic because the private attribute cannot be inherited. please read this sentence carefully if the parent class has private attributes. The method of the parent class serves only the private attributes of the parent class. The following describes how to use a series of columns. This example looks strange. a new attribute $ sal is defined in the subclass, but the system returns the attribute of the parent class. Copy codeThe code is as follows: Class employe

Please take a closer look at this sentence if the parent class has a private property. Then the method of the parent class serves only the private property of the parent class.

Use the Kong Community Edition (Community edition v1.3.0) to build a load balancer, since Kong is based on Openresty and Openresty is a two-time package for Nginx, all many of the configuration items are similar to Nginx. To see a more typical Nginx load balancing configuration Upstream Hello { server localhost:3000 weight=100; Server localhost:3001 weight=50; } server { listen ; Location/hello { proxy_pass Http://hello }
