The present invention will be further described in detail below with reference to the accompanying drawings and embodiments in order to make the present invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1 , a flowchart of a first embodiment of the present invention provides an upgrade method based on a task template, where the method includes the following steps:

In step S101, the common operations are encapsulated, and the encapsulated functional units are combined to form a task template according to the upgrade requirement;

As shown in Figure 2, it is a task template editing example diagram, which encapsulates the operations commonly used in the upgrade process, and is packaged as a backup of files and directories, file transfer, shell script execution, database script execution, database backup, and man-machine command execution. Function, each function consists of a number of logically sequential operations, through which a function is completed.

For example, backup of files and directories includes creating a backup destination directory, creating a backup timestamp directory, and executing a copy command;

The file transfer includes the operation of transferring the file from the local (put) to the ftp server and the remote server fetching the file from the ftp server (get) the past operation;

Shell script execution includes transferring the shell to the remote server, changing shell execution permissions, and executing shell script operations;

Database script execution includes transferring database scripts to remote servers, connecting to databases, and executing database scripts;

Database backup includes connecting to the database and executing database backup commands;

The man-machine command includes sending the command itself. A task template is formed by combining these functions as needed in the upgrade process. As can be seen from Figure 1, the first combination of templates is very convenient. Just drag the packaged operation to the upgrade process tree on the right side and fill in the key attributes to complete the template creation. At the same time, the template is also very flexible. The steps of the template can be adjusted arbitrarily, so that each project can customize its own template according to the project's own situation, thus implementing its own upgrade process; finally, the way to package the operation into functions is also very easy to expand, if there is a new The function needs to be added to the function list on the left side of the new function, and the new function can be added and the compatibility expansion of the original function can be realized.

Each operation defines attributes such as execution user, execution timeout, pause after execution, description of this step, etc. By filling in these attributes, the steps of the entire upgrade template can be displayed in an explanatory language, which is very convenient. The user understands.

Step S102, the local server establishes a communication channel with the remote server through a socket (socket) connection;

The communication channel is based on some protocol contents of telnet and SSH to complete the session simulation of telnet and SSH. As long as the device's IP information and the logged-in username and password are filled in, an automatic connection to the remote server can be achieved. And through the input and output of the socket, the transmission of the command and the processing of the return of the execution result are realized.

Specifically, as shown in FIG. 3, it is a schematic diagram of socket communication. The local server establishes a connection with a remote server through socket communication, and sends a command to a remote server through a socket input stream (Input Stream), and outputs a stream through the socket (Output Stream) ) to get the logs and results returned by the remote server execution command. Involving the operation of the file, through the ftp protocol, first transfer the file from the local server to the ftp server, and then send the command to the remote server through the socket, so that the remote server obtains the file through the ftp protocol to the ftp server (get) Down, thereby completing the transfer of files from the local server to the remote server.

The purpose of this process is to first simulate the underlying environment of manual execution, and then This environment simulates other operations.

Step S103: Parse the task template into an operation command, and execute the operation command after sending the operation command to a remote server.

Specifically, as shown in FIG. 4, it is a flowchart for executing a task template, including,

In step S401, the task template is read, and when the template task is executed, the template is parsed into a packaged functional unit, and then each functional unit is parsed into a series of logically ordered commands;

Step S402, executing a command on the remote server through the socket connection. If the command is successfully executed, determining whether all the commands have been executed. If all the commands have been successfully executed, the function is considered to be successfully implemented, otherwise the subsequent commands are continued; If the execution fails, the error processing flow is entered.

This process is actually a simulated remote login to the server, manually enter the command to execute.

Correspondingly, for each function of the package, the specific execution process is as follows:

Backup of files and directories, first establish a connection with the remote server through socket communication, and then send a backup command to the remote server to complete the backup.

The man-machine command execution first establishes a connection with the remote server through socket communication, and then sends the man-machine command to be executed to the remote server for execution.

Database backup, first establish a connection with the remote server through socket communication, put the backup script to the ftp server, then send the get script command to the remote server, the remote server then get the backup script to the ftp server, and finally send the command to execute the backup script. Give the remote server a backup of the database.

Shell script execution, first establish a connection with the remote server through socket communication, put the shell script to the ftp server, then send the get command to the remote server, then the remote server to the get shell script on the ftp server, and finally send the command to execute the shell script to the remote server, Perform shell script execution.

File transfer, first establish a connection with the remote server through socket communication, put the file to the ftp server, then send the get file command to the remote server, the remote server to the ftp server get file, complete the file transfer.

Database script execution, first establish a connection with the remote server through socket communication, put the database script to the ftp server, then send the get command to the remote server, then the remote server to the ftp server get database script, and finally send the command to execute the database script to the remote The server, the execution of the database script.

From the above process, the backup of files and directories is similar to the communication process of human-machine command execution, but the backup of actual files and directories, and finally the backup command is a series of commands, including the creation of backup target directory, disk space detection, File copying, etc., and man-machine command execution only needs to send the command to be executed. Although the communication process is similar, the actual steps are very different, mainly in the fact that the last command sent is actually a series of logical sequences. Command combination, not just a single command. Similarly, database backup, shell script execution, and database script execution are similar in communication process, but the actual steps in the execution process are quite different. For example, database backup also needs to create backup target directory, detect disk space, and connect. Database and so on; while shell script execution needs to change the execution permission of the shell, etc.; database script execution needs to connect to the database without detecting disk space.

Implement some functions that require client tools to achieve the complexity of the upgrade process due to the use of too many tools. If the ftp operation involved in the upgrade process is split into two steps, the file is first uploaded from the local to the ftp server, and the put operation is implemented by the program, and the ftp server to the remote server is passed by the program to the device. The socket connection initiates a get operation and gets the file to the remote server. The transfer of files from the local server to the remote server is done through a two-step ftp operation. The script execution part of the template involved in the template, after connecting to the remote server, call the built-in shell script on the remote server carry out. This implements the telnet/SSH client, ftp client, database client and other functions, so that the entire upgrade process is controlled within a tool, avoiding too many tools to use back and forth. At the same time, the entire upgrade process is automatically executed in series by the program, which also avoids the omission of the execution process caused by the switch back and forth during the manual operation, which greatly improves the accuracy and efficiency of the execution.
