Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
As shown in fig. 1, a remote instruction management system of a remote server, the system connecting a terminal and the remote server, the system comprising:
(1) the command line identification module is used for carrying out mode matching on user input and forming a first instruction;
the pattern matching of the embodiment matches the instruction input by the user through the pattern of < command > [ < arg > ] [ options ], thereby improving the normalization and the effectiveness of matching commands, parameters and user options; the matching information in the pattern matching includes the following setting contents:
the torchptop matching instruction is used for finding out a process with higher consumption of the target server;
the torchpstate matching instruction is used for checking whether the state of the target process is abnormal or not;
the torchpinfo matching instruction is used for checking the internal emotion scheduling condition and the current running condition of the process;
the torch recog matching instruction is used for debugging the suspicious function and tracking the stack process;
the torch update matching instruction is used for updating an instruction code;
the torch script matching instruction is used for establishing a task or recovering abnormal data through a script;
the torch run matching instruction is used for executing a target server specified function;
the torch sysinfo matching instruction is used for viewing system information;
the torch-h/-v match instruction is used to expose help or version number, where-h after command represents help information exposure for a specified command, -v is version number.
The setting is as follows: the first parameter, torch, is the name of the system, the second parameter, ptop, pstate, pinfo, etc. are instructions, and the third parameter, prefixed by a minus number, represents a user option, e.g., -c is a cookie.
If the first instruction is matched with the matching information, the first instruction passes verification to form an effective first instruction; and if the matching is not passed, finishing all the steps.
(2) The instruction configuration module is used for configuring the first instruction and generating a second instruction, and the configuration comprises information configuration and instruction configuration; the second instruction includes configuration information and user parameters.
The information configuration is a second instruction configuration such as: the name and address of the remote server and configuration information such as Cookie codes for establishing the trust of the remote server; the format of the configuration information is as follows: the configuration information is in middle brackets, the data is in curly brackets, and the configuration information is presented in KV key value pairs, such as: { node, 'tst @ localhost' }, { cookie, 'abc' };
the instruction configuration is to configure an instruction for a second instruction as a user parameter of the second instruction, and the format of the user parameter is as follows: { commands, [ { cookie, $ c, ' Erlang cookie to use ' }, where $ c is replaced and used as option-c, makes a very good extension on the command system's framework, i.e., solves the persistent integration problem caused by insufficient extensibility.
The module is mainly used for configuring the address of the remote server and the Cookie code used for establishing the trust of the remote server, and the remote server trusts the connection access only if the Cookie code of the remote server is consistent with that of the system.
(3) The instruction synchronization module is used for constructing a new internal process in the remote server to serve as an interpretation and operation environment of the second instruction; the internal process adopts a tracking mode, and the process tracking is realized by marking a process dictionary of the process.
In this embodiment, the state of the internal process is marked as hidden node process, and when the system establishes connection with the remote server, the remote server is invisible to the system, so that not only is the problem that the remote server mistakenly considers the system as a service child node thereof to cause confusion of identification avoided, but also the problem that a developer does not care about the identity of an accessor is avoided.
And then, the second instruction extracts the server address and the Cookie code of the server and initiates a TCP request, the remote server firstly receives the handshake request of the SOCKET, the server compares the Cookie code again, and the connection is marked as effective connection after the Cookie code is confirmed to be consistent.
Then, the system sends the configuration information of the second instruction and the related user parameter to the interpretation running environment of the second instruction at the same time, and waits for a third instruction. After receiving the confirmation that the second instruction environment of the server is constructed, the system sends a third instruction, wherein the purpose of the third instruction is to explain and execute the instruction content of the second instruction, so that the whole instruction synchronization process is completed.
(4) And the remote operation module receives a third instruction from the terminal, interprets and executes the second instruction, and returns a function operation result and an operation step.
The third instruction is to execute the second instruction, and then the second instruction is run, and the running will generate two results, the first is the result of running the specified function, and the second is the result of running the process stack process, and the two results will be returned to the terminal through the connection and presented to the user of the system. And after the scheduling is finished, the terminal displays the result, the server instruction process is closed, the terminal session is closed and quit, and the life cycle of one instruction is finished.
(5) A hot update module for pushing the compiled bytecode file to the remote server and replacing a fault code in the remote server;
firstly, module codes to be updated need to be prepared, then the module codes are compiled into byte code files, and the byte code files are transmitted to a root directory operated by a terminal; the system reads the compiled file in a binary mode, takes the byte codes as user parameters of a second instruction, starts to receive the file stream after the target server receives the second instruction, and returns to the terminal to finish receiving the file after the second instruction is received; and finally, the terminal confirms that the second instruction is finished, namely, the terminal sends a load _ bind instruction before a third instruction, the target server receives the load _ bind and loads the load _ bind to the static code module stack in a binary mode, and then the terminal returns to finish loading the replacement reference.
(6) The remote monitoring module is used for monitoring the memory information of the remote server;
and configuring and assembling the ptop instruction with the monitoring attribute into a second instruction, uploading user parameters serving as the second instruction to an internal process, and collecting memory overhead, scheduling times, a current operation function and a process mailbox queue of a system process so as to perform sequencing.
(7) And the remote debugging module is used for debugging the progress of the terminal, the node and each module in the system.
The system of the embodiment can receive and recognize a first instruction input by a user, and generate a second instruction by combining system configuration information and user parameters, and then the system can connect and inject a corresponding service internal process in a server according to a server name or address in the configuration information, and process marks are carried out on a process dictionary on the running environment and the stack and stack processes of the internal process; finally, the completion of the reception of the second instruction of the server is confirmed, a third instruction is sent to the marked process, the second instruction is explained and executed, and the result and the operation process of the process marking are returned after the completion; therefore, the requirements of a developer on remote monitoring, operation, updating and debugging of the remote server are met, and the development and management efficiency is more efficient and convenient.
