Abstract
The invention provides a method and a system for switching servers. The method includes that a first server transmits a listening port handle request to a second server which provides service at the moment; the first server receives an acknowledgment message from the second server; the second server continues providing the service if the acknowledgment message is a failure acknowledgment message; the second server transfers a listening port handle if the acknowledgment message is a success acknowledgment message; the second server completely processes a stock request, the stops serving and is withdrawn; the first server acquires the listening port handle from the acknowledgment message; the first server performs I/O (input/output) operation on the acquired listening port handle; the first server provides service. The method and the system have the advantage that the servers can be switched over by the aid of the method and the system.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and system of switching server.
Background technology
When carrying out web server upgrading, conventionally adopt following two kinds of modes:
First kind of way is: web server must first stop the web server of early version before upgrading, and the server version then more renewing is restarted new server after replacing.In this case, in the time consuming at escalation process, cannot provide web services to user, can cause the interruption of regular traffic.
The second way is: the web server of early version, after receiving specific Event triggered, starts the web server of redaction, and in this case, the web server of redaction has been inherited all features and property value and the data of the web server of early version.Although this technology can guarantee the operation of web server and uninterruptedly can't cause the interruption of regular traffic, contain following risk:
1. the web server of redaction can be carried out unconfined operation to all data of the web server of early version and resource, likely can have influence on the behavior of original business, has increased the uncertain risk of business conduct.
2. if the web server of some special resource redactions that the web server of early version has is not used, the web server of redaction also must be carried out special processing to it, otherwise can cause the even leakage of the waste of system resource.
3. the web server of redaction must be familiar with the web server exploitation details of early version in exploitation with aspect safeguarding, the relevance of new early version web server is strengthened.Increased the development and maintenance cost of redaction server.
Summary of the invention
In view of this, the invention provides a kind of method and system of switching server, for carrying out Server switching.
The invention provides following technical scheme:
1. a method for switching server, is characterized in that, described method comprises:
First server is to providing the second server of service to send listening port handle request;
First server receives the response message from second server;
Failed response message if, second server continues to provide service;
Successful response message if,
Second server is sold listening port handle;
Second server stops serving and exiting after handling storage request;
First server is obtained listening port handle from response message;
First server is carried out I/O operation to obtained listening port handle;
First server provides service.
2. the method as described in technical scheme 1, is characterized in that, the first and second servers are the server based on ICP/IP protocol.
3. the method as described in technical scheme 1, is characterized in that, described the first and second servers are web server, ftp server, TELNET server or streaming media server.
4. the method as described in one of technical scheme 1-3, is characterized in that, first server when receiving the replying of failure, failed regeneration information.
5. a system for switching server, is characterized in that, described system comprises first server and second server, wherein
First server is to providing the second server of service to send listening port handle request;
First server receives the response message from second server;
Failed response message if, second server continues to provide service;
Successful response message if,
Second server is sold listening port handle;
Second server stops serving and exiting after handling storage request;
First server is obtained listening port handle from response message;
First server is carried out I/O operation to obtained listening port handle;
First server provides service.
6. the system as described in technical scheme 5, is characterized in that, the first and second servers are the server based on ICP/IP protocol.
7. the system as described in technical scheme 6, is characterized in that, the first and second servers are web server, ftp server, TELNET server or streaming media server.
8. the system as described in one of technical scheme 5-7, is characterized in that, first server when receiving the replying of failure, failed regeneration information.
Utilize method and system of the present invention, can realize the switching of server.That in addition, utilizes that the present invention can also realize web server, ftp server, TELNET server, streaming media server does not shut down upgrading.
Accompanying drawing explanation
Fig. 1 is the method according to switching server of the present invention; And
Fig. 2 is the system according to switching server of the present invention.
Embodiment
Below in conjunction with accompanying drawing, describe the preferred embodiments of the present invention in detail, identical reference number represents identical element in the accompanying drawings.
Fig. 1 is according to the method for the switching server of this aspect.Fig. 2 is the system according to switching server of the present invention.As shown in the figure, system according to the present invention comprises first server 1 and second server 2.This first server 1 and second server 2 are the server based on ICP/IP protocol, for example, can be web server, ftp server, TELNET server, streaming media server.
In step 101, first server 1 is to providing the second server 2 of service to send listening port handle request.
In step 102, the response message that first server 1 receives from second server 2.
In step 103, first server 1 determines whether this response message is successful response message, if YES, performs step 104, otherwise performs step 105
In step 104, second server 2 is sold listening port handle; Second server 2 stops serving and exiting after handling storage request; First server 1 is obtained listening port handle from response message; The listening port handle that 1 pair of first server is obtained carries out I/O operation; First server 1 provides service.
In step 105, second server 2 continues to provide service.Alternatively, first server 1 failed regeneration information.
Thus, utilize method and system of the present invention, can be not shutting down, from second server, be switched to first server non-interrupting service in the situation that.Furthermore; for example, when first server server (the being web server) second server that is redaction is legacy version server; realized do not shut down, the server updating of non-interrupting service, avoided because server updating need to stop the web server of legacy version, causing in prior art the situation of service disconnection.
Secondly, resource security.Thereby the present invention has successfully avoided in the second way of prior art, the web server of two versions of the old and new is to the succession of system resource and authority and share the fail safe that the potential safety hazard brought has improved system.
The 3rd, service security.The present invention has successfully avoided the web server of redaction to having the operation of business in the web server of early version, has avoided the business operation inconsistency causing because of system upgrade likely occurring.
The 4th, exploitation is simple.The present invention has successfully avoided the exploitation of the web server of redaction must know the ins and outs problem of the web server exploitation of early version, has effectively reduced the development and maintenance cost of redaction server.
In view of these instructions, those of ordinary skill in the art will easily expect other embodiments of the invention, combination and modification.Therefore,, when reading in conjunction with above-mentioned explanation and accompanying drawing, the present invention is only defined by the claims.
