specific Embodiment approach

[0042] In order to realize the function described in the present invention, the specific implementation is as follows:

[0043] 1. Add page cache server and database cache server to the website.

[0044] 2. Install caching programs such as Nginx (a lightweight web server / reverse proxy server and email (IMAP / POP3) proxy server) on the web server, and cache common pages in the page caching server. For some non-common pages, such as personalized pages, etc., modify the program to transfer the personalized content from other URL (Uniform Resource Locator) fetching.

[0045] 3. Provide a database cache server for the database, cache common database query content on the database cache server, and ensure that commonly used database query results can be obtained in the database cache server.

[0046] 4. Reconfigure the permission logic of the website to ensure that the system can obtain data from the database cache server to complete user authentication when the database is down and...

Abstract

The invention relates to a system and method for realizing the restoration of a web service in case of a crash of a database. The system comprises a page caching server and a database caching server, wherein the page caching server is used for acquiring a general web page from a web server of the web service for caching, and the database caching server is used for caching general database query content of the web service. The structure is adopted for the system and method for realizing the restoration of the web service in case of the crash of the database, page caching and database caching are reasonably set, asynchronous personalized data are acquired, reasonable strategies and services are set, and web page caching, asynchronous personalized data loading, database caching and other technologies are applied comprehensively, as a result, the web service can be quickly restored in case of the crash of the database, a user website can still provide all or part of service under the circumstance that the database has the crash, normal access by users of the web site can be guaranteed, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of website services, in particular to the technical field of website database recovery when downtime, and specifically refers to a system and method for realizing website service recovery under the condition of database downtime. Background technique [0002] In the existing website, the database occupies a very core position. Almost all user operations require the participation of the database. The simple topology of the entire website system is as follows: figure 1 shown. If the database cluster in the system is down, such as: SAN (Storage Area Networking, storage area network) failure, it will cause all pages of the website to be unable to provide any services, and the entire website will be paralyzed. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and to provide a database server that can still provide all or ...
