CN104320344A - Dynamic application cluster implement method based on Nginx - Google Patents

Abstract

The present invention provides a kind of method based on Nginx to realize the dynamic application cluster, provides relevant information to be applied to the system, and described relevant information includes the IP of application, port and domain name; Perform maintenance to form a dynamic routing table; Nginx forwards according to the maintained dynamic routing table when accessing the application; add or reduce application information in the dynamic routing table, and Nginx can perform dynamic forwarding without restarting.

Description

A method of implementing dynamic application cluster based on Nginx

technical field

The invention relates to the technical field of computer applications, in particular to a method for realizing dynamic application clusters based on Nginx.

Background technique

With the development of information technology and the continuous improvement of the degree of informatization, more and more audience users have developed a new system, and the information system is developing towards clustering and centralized management. In traditional cluster management, modifying members in the cluster will cause request interruption, and this method was invented to solve this problem.

Contents of the invention

The purpose of the present invention is to provide a method for realizing dynamic application cluster based on Nginx.

The object of the present invention is achieved in the following manner, and concrete steps are as follows:

a) Provide relevant information of the application to the device, and the relevant information includes the IP, port and domain name of the application;

b) The device maintains the applied IP, port and domain name information in memory to form a dynamic routing table;

c) When accessing the application, Nginx forwards according to the maintained dynamic routing table; d) Add or reduce application information in the dynamic routing table, and Nginx can perform dynamic forwarding without restarting.

The application is a web application, and in step a), the state required by the application needs to be started.

The dynamic routing table is a data structure in key-value format, in which the domain name exists as a key, and the value is a combination of IP and port.

Description of drawings

Fig. 1 is a flow chart of monitoring and self-managing system processes according to the present invention.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Generally, the physical structure of the system is divided into three layers. The first layer is the physical load balancer (F5); the second layer is the software load balancer (Apache or Nginx); the third layer is the application server running the system. This method solves the problem of dynamic load from the second layer to the third layer. Traditionally, the load forwarding from the second layer to the third layer is realized by modifying the configuration file of the second layer load balancer. After modifying the configuration file, the process needs to restart the load balancer, which will cause request interruption, which is very inconvenient to use.

The implementation steps of the method of the present invention are described below with reference to FIG. 1 .

In step S101, relevant information of the application is provided, and the relevant information includes the IP, port and domain name of the application;

In step S102, the device maintains the IP, port and domain name information of the application in memory to form a dynamic routing table. Examples of data are as follows:

Name: Status

app1 192.168.1.1:8080

In step S103, Nginx forwards according to the maintained dynamic routing table when accessing the application. For example, the ip and port of Nginx are 192.168.1.0:80. After the forwarding between Nginx and application app1 is configured, access to app1 can be accessed through 192.168.1.0:80/app1.

In step S104, the application information is increased or decreased in the dynamic routing table, and Nginx can perform dynamic forwarding without restarting. Add nodes to app1 in S102, as follows:

Name: Status

app1 192.168.1.1:8080

app1 192.168.1.2:8080

app1 192.168.1.3:8080

Accessing app1 via 192.168.1.0:80/app1 adds processing power without interrupting requests.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.

Claims (2)

1. realize a method for dynamic application cluster based on Nginx, it is characterized in that concrete steps comprise:

A) provide the relevant information be employed to this device, described relevant information comprises the IP of application, port and domain name;

B) IP of application, port and domain-name information are safeguarded by this device in internal memory, formative dynamics routing table;

C) forwarded according to the dynamic routing table safeguarded by Nginx during access application;
