Background

At present, a lot of systems need to process a lot of service data in the background, and when a large amount of data needs to be processed in real time, a single device often cannot meet the requirements. For this reason, a distributed system is usually adopted to improve the real-time processing capability of the system on data. In a distributed environment, business processes are deployed on many machines in many rooms across the country or even around the world. Not only is the distribution wide, but also the types and the number of business processes are various.

Referring to fig. 1, in a method for controlling a telnet centralized service provided by the present invention, in a specific embodiment, the method specifically includes the following steps:

s11, receiving a control command and a distribution strategy sent by the remote login service client;

and receiving a control command and a distribution strategy which are sent by a client maintaining a first session of the remote login service with a local control process, wherein the control command and the distribution strategy are expressed in the same command line.

In a possible application scenario, for example, an engineer wants to open a function on a certain type of service process a, and sends a control command to open the function through a central console on telnet in the same distributed system as the service process a. The control command and the distribution strategy are expressed in the same command line so as to forward the control command to all or any one of the service processes corresponding to the service type, namely the service process A, indicated by the distribution strategy, and thus, the control command is executed on all the service processes corresponding to the class A service process. In the same command line, the control command may be a standard control command provided by Telnet standard protocol, the distribution policy may be any form of pre-protocol, and the control command and the distribution policy may be separated by some common separator, such as a blank number, a slash, etc.

The distribution strategy comprises specified information of the business process, and is expressed in the form of keywords and a list of selectively carried suffixes.

In one possible design, the present invention prefers the following three possible distribution strategies for distributing the control commands sent by the client:

the strategy is used for sending the control command to all business processes in the distributed system, and the expression form of the strategy is as follows: all, where All is its keyword and its suffix list is empty.

And secondly, the control command is used for sending the control command to all business processes corresponding to the business type specified by the distribution strategy in the distributed system, and the expression form is as follows:

type < Business Process Type name >

In the expression, Type is a keyword, and the suffix list is the Type name of the business process. In some embodiments, multiple type names separated by separators may be allowed to appear as desired.

Thirdly, the control command is sent to any business process corresponding to the business type specified by the distribution strategy in the distributed system, and the expression form is as follows:

any < Business Process type name >

In the expression, Any is a keyword, and the suffix list is the type name of the business process. In some embodiments, multiple type names separated by separators may be allowed to appear as desired.

The central control process provides a plurality of distribution strategies of the control command, and a user can select a specific distribution strategy when operating the central control process so that the central control process distributes the control command sent by a client to a set business process to be executed according to the distribution strategy.

The distribution policy in the embodiment of the present invention may include several types other than the above three types, and is not limited to the above three types, including the keywords (such as ALL, Type, Any) and the suffix list thereof, which may be pre-agreed by a developer when implementing the step, and is not limited herein.

S12, determining one or more service processes in the distributed system corresponding to the distribution strategy from a pre-stored service processing information table according to the distribution strategy;

in the embodiment of the present invention, the distributed system includes a service discovery process, which is used for discovering that the business process in the distributed system joins the system or goes offline in the system. The service discovery process collects and stores the registration information of each service process, and the central control process acquires the registration information of each service process through the service discovery process and stores the registration information in the local service process information table, or deletes the registration information of the offline service process from the service processing information table so as to maintain the service processing information table in real time. And the service processing information table is used for determining the service process corresponding to the distribution strategy by the central control process according to the distribution strategy so as to execute a specific control command.

Preferably, the service processing information table stores registration information of a service process, the registration information of the service process includes a Type name of the service process, and the distribution policy includes specification information of the Type name of the service process, for example, the above-mentioned All keyword may represent specification of an unlimited service process Type name, and the Type, Any and other keywords, and a subsequent suffix list thereof may be used to specify a specific certain Type of service process by giving a service process Type name. Specifically, when all the business processes register with the service discovery process, information such as names of the business processes, type names of the business processes, deployment ip, ports and the like needs to be reported, and the service discovery process stores the registration information in the business processing information table.

Preferably, the registration information of the service process in the service processing information table further includes a name and/or an IP address of a service host in the distributed system where the service process is located, and a port number that is open in the service host, the central control process queries the service process corresponding to the service process in the table according to the distribution policy and obtains the name and/or the IP address of the service host in the distributed system where the service process is located, and the central control process creates a session with the service process according to the name and/or the IP address of the service host and the port number to distribute the control command to each service process through a remote login service.

In one possible embodiment, the business process type of each business process is determined by the data range information processed by the business process, and preferably, the processed data range information of the business process is allocated by the service discovery process. Specifically, the distributed system comprises a central control process, a service discovery process and at least one service process, wherein the at least one service process sends a registration request to the service discovery process, the service discovery process receives the registration request sent by each service process, and after receiving the registration request, a processed data range is allocated to each service process, namely, the type of the data range is specified. When the business processes submit registration requests to the service discovery process, the relevant registration information of the business process is submitted to the service discovery process so that the service discovery process can store the registration information and store the types of the business processes together, and the central control process acquires the registration information to construct the business process information table and updates the business process information table through the service discovery process.

In the embodiment of the present invention, the central control process host and the service discovery process host are implemented in the same computer device or different computer devices.

S13, distributing the control command to each business process through a remote login service;

in the embodiment of the invention, the central control process distributes the control command to each business process which maintains a second session of the remote login service with the local central control process. And the central control process distributes the control command to each service process through the second session.

In a possible design, with the above different examples of the distribution policy, the present invention prefers to distribute the control command to the business processes in the following three ways:

firstly, the control command is distributed to all service processes in the distributed system;

when the central control process is based on a distribution strategy submitted by a client, if the business processes to be distributed specified by the specified information of the distribution strategy are all the business processes in the system, the central control process sends the control command to all the business processes in the system to execute the control command, and each business process feeds back the executed result information to the central control process through the second session so that the central control process feeds back the result information to the client to be displayed on the client.

Secondly, the control command is distributed to all business processes corresponding to the business process type specified by the distribution strategy specifying information in the distributed system;

when the central control process is based on a distribution strategy submitted by a client, if the business processes to be distributed specified by the specified information of the distribution strategy are all the business processes corresponding to the business process type specified by the specified information in the system, the central control process sends the control command to all the business processes of the specified business process type in the system to execute the control command, and each business process feeds back the executed result information to the central control process through the second session so that the central control process feeds back the result information to the client to display the result information on the client.

And thirdly, distributing the control command to any business process corresponding to the business process type specified by the distribution strategy specifying information in the distributed system.

When the central control process is based on a distribution strategy submitted by a client, if a service process to be distributed, which is specified by specified information of the distribution strategy, is any service process corresponding to the service process type specified by the specified information in the system, the central control process sends the control command to any service process of the specified service process type in the system to execute the control command, and each service process feeds back executed result information to the central control process through the second session so that the central control process feeds back the result information to the client to display the result information on the client.

And S14, feeding back result information fed back after each business process executes the control command to the client.

In the embodiment of the present invention, the central control process and each service process maintain a second session of the remote login service and send the control command to each service process through the second session, and accordingly, each service process feeds back the executed result information to the central control process through the second session, so that the central control process feeds back the result information to the client.

In one possible design, the central control process sends the result information fed back by each business process to the client for summarizing at the client, or the central control process sends the result information fed back by each business process to the client after summarizing so as to be displayed at the client.

Referring to fig. 2, in another embodiment of the present invention, a step S15 is further included for receiving a registration request of any new service process, and adding registration information of the new service process to the service processing information table; or, monitoring the survival state of any service process already existing in the service processing information table, and deleting the registration information of the service process from the service processing information table when any service process does not exist.

The distributed system comprises a service discovery process, and the service discovery process is used for discovering the service processes in the distributed system, adding the registration information of each service process into a service processing information table, or deleting the registration information of the offline service process from the service processing information table to maintain the service processing information table.

The central control process obtains the host names, the IPs and the port numbers of all the business processes in the distributed system through the service discovery process, stores the host names, the IPs and the port numbers in a local business process information table, and dynamically maintains the table in real time through the service discovery process.

Preferably, the service discovery process and the central control process exist in the same computer device or different devices, and accordingly, the step of adding the registration information of the newly added service process to the service processing information table or deleting the registration information of the service process from the service processing information table is performed by another host different from the local host in the distributed system or performed by the local host.

It should be noted that when the central control process distributes the control command to each service process for the first time, if there is no second session of the telnet service, the second session needs to be established in advance, and it may not be considered to close the second session. If the second session is not closed, the previously established second session may be invoked when the control command is distributed again. Of course, the second session between the central control process and each business process, no matter which service host the business process resides in, is independent of the second session between the central control process and another business process.

The central control process, the service discovery process and each service process can be flexibly combined according to the design requirements of the central control process, the service discovery process and each service process in a distributed system, and can be realized in the same service host or different service hosts without obstructing the realization of the invention.

Referring to fig. 3, to further illustrate the telnet centralized service control method of the present invention, the telnet centralized service control method is described in a modularized manner, and a telnet centralized service control apparatus is provided, which includes, in one embodiment, a receiving module 11, a determining module 12, a distributing module 13, and a feedback module 14, and further includes, in the embodiment shown in fig. 4, an updating module 15. Wherein the content of the first and second substances,

the receiving module 11: the system comprises a remote login service client, a server and a server, wherein the remote login service client is used for receiving a control command and a distribution strategy sent by the remote login service client;

type < Business Process Type name >

any < Business Process type name >

The determination module 12: the system comprises a distribution strategy table, a service processing information table and a service processing information table, wherein the distribution strategy table is used for storing service processing information of a plurality of service processes in the distributed system;

The distribution module 13: the system is used for distributing the control command to each business process through a remote login service;

The feedback module 14: and feeding back result information fed back after each business process executes the control command to the client.

Referring to fig. 2, in another embodiment of the present invention, an updating module 15 is further included for receiving a registration request of any newly added service process, and adding registration information of the newly added service process to the service processing information table; or, monitoring the survival state of any service process already existing in the service processing information table, and deleting the registration information of the service process from the service processing information table when any service process does not exist.

In a possible application scenario of the present invention, for example, a user wants to query stock data from 2014 to 2015, the data is distributed and stored on different service processing devices, the user only needs to operate a control command to query through a central control process on telnet, the control command includes a distribution policy of the query command, the central control process correspondingly finds a plurality of corresponding service processing devices storing the stock data according to the distribution policy and forwards the control command to the service processing devices to perform a query operation, and the service processing devices correspondingly feed back result information of the stock data queried by the service processing devices to the central control process so that the central control process directly presents the result information to the user or feeds back the result information to a client to display the result information of the stock data on the client.

Through the implementation of the invention, the user does not need to care about the deployed ip and the port of each service processing device and does not need to log in the console of each service processing device to execute the same query command, thereby not only having low efficiency, but also being easy to miss.

In the implementation of the invention, a user only needs to know the ip port of the central control process and only needs to log in the console of the central control process, and a specific type of service process is specified to operate a command, the data range of the specific type of service for representing the processing of the service process is the stock data from 2014 to 2015, and correspondingly, the control command is executed on all the devices of the service process and the corresponding stock data result information is fed back, so that the implementation is convenient and quick.

With reference to the foregoing embodiments, the greatest effect of the present invention is to provide a method and a corresponding apparatus for controlling a telnet centralized service, where a control command sent by a client is forwarded to other corresponding service devices in a telnet standard protocol manner through cooperation of a central control process, a service discovery process, and other service devices in a distributed system, so as to implement processing of the control command sent by the client and corresponding feedback of processing result information to the client.

Referring to fig. 5, the present invention provides a method for controlling a telnet centralized service, specifically to adapt to the method implemented by the server, which is implemented by the client. In one possible implementation, the method implemented at the client includes:

s21, sending control commands and distribution strategies for specifying one or more business processes in the distributed system to the central control process through the telnet service.

And the client sends a control command and a distribution strategy to the central control process through a first session of the remote login service maintained by the local control process, wherein the control command and the distribution strategy are expressed in the same command line.

In a possible application scenario, for example, an engineer wants to open a function on a certain type of service process a, and sends a control command to open the function through a central console on telnet in the same distributed system as the service process a. The control command and the distribution strategy are expressed in the same command line so as to forward the control command to all or any one of the service processes corresponding to the service type, namely the service process A, indicated by the distribution strategy, and thus, the control command is executed on all the service processes corresponding to the class A service process.

the strategy is used for sending the control command to all business processes in the distributed system, and the expression form of the strategy is as follows: and (3) All.

type < Business Process Type name >

any < Business Process type name >

The central control process provides a plurality of distribution strategies of the control command, and a user can select a specific distribution strategy when operating the write control process so that the central control process distributes the control command sent by a client to a set business process to be executed according to the distribution strategy.

The distribution policy in the embodiment of the present invention may include several types other than the above three types, which are not limited to the above three types and are not limited herein.

And S22, receiving result information fed back after the central control process distributes the control command to each service process according to the distribution strategy.

In the embodiment of the present invention, the distributing the control command by the central control process according to the distribution policy specifically includes the following three ways:

Secondly, the control command is distributed to all business processes corresponding to the business process type specified by the distribution strategy specification information in the distributed system;

And thirdly, distributing the control command to any business process corresponding to the business process type specified by the distribution strategy specification information in the distributed system.

And S23, displaying the result information.

In the embodiment of the present invention, after each service process executes a specific control command, the result information is fed back to the central control process through the second session, and the central control process presents the result information to a user or feeds back the result information to the client to display the result information on the client.

The method has the greatest beneficial effect that the method is based on the standard telnet protocol, and can conveniently control other processes in the distributed system through one central control process. It only needs one central control process to provide services with standard telnet protocol. Specifically, the user may log in the central control process in a telnet manner to remotely control each service process in the distributed system.

The method is simple to implement, and a set of web background does not need to be built by spending much time and energy. The method is a more familiar and friendly way for users, and improves the service quality.
