Session management method

Abstract

The invention provides a session management method. The session management method comprises the following steps of: taking nginx as a reverse proxy, and developing a nginx plug-in to provide a cluster front end of an application portal; using Ivs (Linux Virtual Server) to build a high-availability cluster based on reverse proxy software of the nginx; using cluster redis as a uniform session for storage; developing a session management module in the reverse proxy; and stripping session data and an application server. The session management method has the advantages of high execution efficiency, high availability and low cost; through expired processing of the session and the stripping from the application server, the problem of desynchrony of the sessions among application server clusters can be effectively avoided, the application servers are independent to one another, the session synchrony is not needed, and better elasticity and performance can be provided.

Description

technical field [0001] The invention relates to a computer program management method, in particular to a session management method. Background technique [0002] For existing Internet applications based on the http protocol, a single server cannot meet business needs. Therefore, an application server cluster is required. As the business expands, the server cluster often requires scalability, that is, when the business expands, the performance of the entire method can be improved by adding servers. [0003] Due to the need to give users a unified entrance, the application server cluster needs an entrance for business distribution. Moreover, due to the stateless nature of the http protocol (the http protocol does not necessarily maintain the connection, that is, two requests from the same client are completely independent requests from the server), the server-side web business must use the session to maintain (such as the mall The goods in the shopping cart, no matter how m...

Problems solved by technology

And there will be a long interval in between. At this time, the session on the server is likely to have expired, causing the user to log in again and seriously affecting the experience.

Modern apps generally have an automatic re-login function, which will bring about a series of problems in session reconstruction, causing the application server of existing web applications to manually manage the session life cycle and save it persistently

As in the shopping cart example above, since the session of the app may expire, it is impossible to use the sticky session method to build the entire server cluster

[0006] The resource utilization rate of the existing cluster solution is very low, and the session information that has to be saved for a long time occupies a large amount of server-side memory of all application servers, causing the entire method to be unstable; it is difficult to synchronize the session; if session replication is used, it will be huge Increase the load of the intranet between server clusters. Generally speaking, when the number of servers exceeds 10, large-scale session replication may take a long time, which will cause huge impact and errors on the entire method business; the existing cluster solution is aimed at handheld devices The support is not good, and the application layer needs to do a series of additional processing, and it will affect the cluster solution
