Description
Technical Field
The invention belongs to the field of online software service, and particularly relates to a distributed operation method for realizing uninterrupted service.
Background
Currently, most of the known online service software programs are run on a single server, and the software programs are complete on the single server. However, a single point of failure of a server, either system hardware failure, system software failure, or application software single/joint failure, is unavoidable or circumvented, resulting in an interruption of the functionality and services provided by the currently running service software.
In order to prevent service interruption, in the conventional server software, the same software is generally installed on a plurality of servers to form a master-slave structure, but the problem is not fundamentally solved. There are still several problems as follows: (1) only the master server works and the slave server is idle when the system works normally; (2) if the main server is abnormal, the service is switched from the main server to the slave server, the switching time is needed, and the same is true when the main server is recovered to be normal and the service is switched back; (3) when the fault is switched, the connection established between the client and the main server is forcibly interrupted, all the developed services are completely suspended, and after the main server is recovered to be normal, the connection between the client and the standby server is also completely interrupted, and the connection with the main server needs to be established again; (4) the configuration of the master server is higher than that of the slave servers, and if the master server goes down in a traffic peak, the standby server cannot support the traffic; (5) if the traffic volume of a certain service is increased sharply, hardware configuration needs to be added to compensate for the increase in the traffic volume, but the accumulation of the hardware performance of the server is limited, and if the traffic volume increases exponentially, the configuration requirement of the server becomes infinite.

Example one
As shown in fig. 1 to 3, the distributed operation method for implementing uninterrupted service provided by this embodiment includes the following steps.
S101, installing view layer code packages of service software programs on a plurality of view servers, and installing model layer code packages and control layer code packages of the service software programs on a plurality of function pool node servers.
In the step S101, the service software program is used for performing service data processing when called, and returning a service output image, which may be, but is not limited to, a service software program for medical informatization management. The view server and the function pool node server can be connected in a remote communication mode to achieve distributed deployment of service software programs. As shown in fig. 2 and 3, by installing the service software program in a distributed manner, one view can be provided by a plurality of function pool node servers at the same time, thereby avoiding the problem of service interruption caused by the crash or abnormality of a single function pool node server. In addition, the function pool node server includes a provider for implementing service functions and services and/or a user for scheduling service usage, and the provider and the user are respectively packaged with their communication ports.
And S102, registering the unique identifier of the service software program, the IP address of the function pool node server and the communication port in a registration center.
In step S102, the unique identifier is used to uniquely identify the corresponding service software program, which may be, but is not limited to, a service software program name or a digital code. The registry is used for registering and discovering the provider and the user corresponding to the service software program, and preferably adopts a network server with a UPS (Uninterruptible Power System) uninterrupted Power supply. In addition, the registration IP address of each function pool node server adopts 0.0.0.0, so that synchronous calling of a plurality of function pool node servers can be ensured during subsequent calling, and service interruption caused by breakdown or abnormity of a single function pool node server is avoided.
And S103, when the client requests for service, the service request of the client is transferred to at least one view server through the scheduling of the reverse proxy server.
In the step S103, the client is configured to initiate a service request, and acquire and display a returned service output image, which may be, but is not limited to, a web service terminal, a user service terminal, or a wechat service terminal. Considering that the view server may also have a fault, the present embodiment introduces multiple view servers to consume the service data processing results of multiple function pool node servers at the same time, and introduces a reverse proxy technology to solve the scheduling problem of multiple view servers, thereby further avoiding the problem of service interruption caused by a single view server being crashed or abnormal.
In step S103, the number of the reverse proxy servers may also be set to be multiple, and before step S103, the client may obtain the IP address and the communication port of each reverse proxy server through a Domain Name System (DNS) Domain Name resolution server, so that the client can be ensured to transfer the service request to the view server through the reverse proxy server, and the problem of service interruption caused by a crash or an abnormality of a single reverse proxy server is avoided. Preferably, in order to prevent the DNS nameresolution server from malfunctioning, the DNS nameresolution server includes a master DNS nameresolution server and at least one slave DNS nameresolution server. Since the DNS nameresolution server itself does not process traffic and has no requirement for configuration, it can be determined that the DNS nameresolution server is never disconnected.
S104, after receiving the service request, the view server checks the unique identifier of the current available service software program in the registration center, then searches the IP address and the communication port of the corresponding function pool node server in the registration center according to the unique identifier of the selected available service software program, and finally calls the model layer code packet and the control layer code packet of the corresponding function pool node server corresponding to the selected available service software program according to the searched IP address and communication port to complete service data processing.
And S105, consuming the service data processing result from the function pool node server through the view layer code packet of the view server corresponding to the selected available service software program to obtain a service output image.
And S106, feeding back the service output image to the client through the reverse proxy server.
Through the steps S101-S106, the service software program can be installed in a distributed mode and called and run by adopting a reverse proxy technology, and service data processing and service output image returning can be completed during calling, so that the normal calling purpose is realized, the stability of the system can be improved in a medium-large service software system, the concurrent processing capability and the transverse expansion capability are realized, and the practical application and popularization are facilitated.
In summary, the distributed operation method for realizing uninterrupted service provided by the embodiment has the following technical effects:
(1) the embodiment provides a solution capable of highly stabilizing the usability of a service software program, namely, the service software program with the traditional MVC architecture is separated into an MC layer code packet (namely, a model layer code packet and a control layer code packet) and a V layer code packet (namely, a view layer code packet), and distributed installation is performed on the MC layer code packet and the V layer code packet and calling operation is performed by adopting a reverse proxy technology, so that the stability of the system can be improved in a medium-large service software system, the concurrent processing capability and the transverse expansion capability are realized, and the practical application and popularization are facilitated;
(2) by introducing the DNS domain name resolution server, the problem of service interruption caused by crash or abnormity of a single reverse proxy server can be further avoided.
The present invention is not limited to the above-described alternative embodiments, and various other forms of products can be obtained by anyone in light of the present invention. The above detailed description should not be taken as limiting the scope of the invention, which is defined in the claims, and which the description is intended to be interpreted accordingly.
