It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For convenience of description, terms or expressions appearing in the embodiments of the present invention are explained below.
A Secure Shell protocol (SSH), which is a security protocol established on the basis of an application layer and provides security for telnet sessions and other network services; the system consists of software of a client and a server; the working mechanism is that a local client sends a connection Qin and Qin to a remote server, the server checks a packet and an IP address of an application and then sends a secret key to the client of the SSH, and the local client sends the secret key back to the server to establish the connection.
The computer shell layer is software for providing an operation interface for a user, and is similar to command.com and subsequent cmd.exe under DOS, and receives a user command and then calls a corresponding application program.
The Process Identifier (PID) is an identification of each Process, and once the program runs, the system automatically allocates a unique PID to the Process, and after the Process is terminated, the PID is recycled by the system and may be continuously allocated to the newly running program.
Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of a method for updating a program, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than that presented herein.
Fig. 1 is a flowchart of an update method of a program according to an embodiment of the present invention, as shown in fig. 1, the update method of the program includes the steps of:
step S102, determining that the JAVA program to be updated is in an open state.
Optionally, the JAVA program to be updated is a program that is already installed on the target server and needs to be updated.
Step S104, closing the JAVA program to be updated;
and step S106, sending the update file of the JAVA program to be updated to the target server.
Here, after determining that the program to be updated is in the on state according to step S102, an update file of the JAVA program to be updated is acquired and transmitted to the target server.
And step S108, starting an update file on the target server to automatically update the JAVA program to be updated.
As can be seen from the above, in the embodiment of the present invention, after it is determined that the JAVA program to be updated is in the open state, the JAVA program to be updated is closed, the update file of the JAVA program to be updated is sent to the target server, and the update file is started on the target server to automatically update the JAVA program to be updated, so that the purpose of automatically updating the JAVA program to be updated is achieved, and the reliability of updating the program is improved.
Therefore, the program updating method provided by the embodiment of the invention solves the technical problems that the manual program updating is easy to generate errors and the reliability is low in the related technology.
As an optional embodiment, before determining that the JAVA program to be updated is in the open state, the program updating method further includes: and establishing a remote connection relation with the target server.
In this embodiment, a server that needs to be updated with a program, i.e., a target server, can be remotely connected through SSH, so as to establish a remote connection relationship with the target server.
Because the secure shell protocol SSH is a security protocol established on the basis of the application layer and can provide security for telnet sessions and other web services, the remote connection relationship with the target server is established in an SSH remote connection manner, thereby improving the security of information transmission with the target server.
As an optional embodiment, after determining that the JAVA program to be updated is in the open state, the program updating method further includes: acquiring a process control identifier PID of a JAVA program to be updated; generating a predetermined control instruction based on the PID; the control target server runs a predetermined control instruction.
For example, the PID of the JAVA program to be updated may be obtained by jps-1, and then the predetermined control instruction may be generated based on the PID of the JAVA program to be updated. When the target server runs the predetermined control instruction, the JAVA program to be updated running on the target server may be ended.
Since the kill-9pid may send sigkill to the process with process number pid, sigkill cannot be either trapped by the application or blocked or ignored, i.e., the action is to end the specified process immediately. That is, the application program cannot sense the sigkill signal at all, and the sigkill signal is processed by the operating system receiving the sigkill signal under the condition of no preparation, so that the application program has no chance of releasing the currently occupied resources, and the program can continuously occupy the allocated PID.
Therefore, in the embodiment of the present invention, the above-described predetermined control instruction may be written based on kill-9 pid.
It should be noted that, since the computer shell layer refers to software for providing an operation interface for a user, similar to command.com and subsequent cmd.exe under DOS, it receives a user command and then calls a corresponding application program. Therefore, in the embodiment of the invention, software for providing an operation interface for an operator can be based on the shell script.
As an alternative embodiment, the closing of the JAVA program to be updated includes: determining that the target server responds to a predetermined control instruction; monitoring the operation of the target server for operating a preset control instruction; and when the monitoring result shows that the target server successfully runs the preset control instruction, determining that the JAVA program to be updated is in a closed state.
By the embodiment, whether the JAVA program to be updated is in the open state can be accurately determined.
As an alternative embodiment, sending the update file of the JAVA program to be updated to the target server includes: writing a remote copy instruction based on the scp command; and sending the update file of the JAVA program to be updated to the target server through a remote copy instruction.
For example, the update file is sent to the target server through the scp command, so as to improve the security in the transmission process of the update file.
As an alternative embodiment, the starting of the update file on the target server to automatically update the JAVA program to be updated includes: writing a java-jar-based remote start instruction; and starting an update file on the target server through a remote start instruction so as to automatically update the JAVA program to be updated.
For example, the update of the JAVA program to be updated may be accomplished by opening an update file on the target server based on a JAVA-jar command.
From the above analysis, the program updating method provided by the embodiment of the invention can be remotely connected to a server to be deployed through SSH based on a shell script mode, obtain the PID of the JAVA program to be updated through jps-l, close the JAVA program to be updated by using kill-9PID, upload the new program (i.e., update file) to a target server through an scp command, and finally start the program through JAVA-jar, so that the automatic updating of the JAVA program is realized, and the efficiency and reliability of updating the program to be updated are improved.
