| 10.203.4.25 | 23 | user4 | halg12@uu |
Optionally, as shown in table 1, the remote access parameter may be stored in a table form in the database 303, as can be seen from table 1, the cluster 301 includes a plurality of server nodes, and the specific number of the server nodes in table 1 is 4, while in practical applications, the number of the server nodes in the cluster 301 may be configured according to practical needs, which is not limited in the present invention, and the remote access parameter is represented by four fields in table 1, and includes: IP address, port number, user name, password, meaning that each field represents is as follows:
IP address: IP addresses representing server nodes in cluster 301;
port number: representing an access port number;
user name: a username for remote access;
password: the password corresponding to the user name.
Through the above access information, it is possible to remotely connect and access the respective server nodes in the cluster 301.
It should be noted that table 1 only shows one form of table storage of the database 303 by way of example, and the present invention is not limited to the form of table 1, and the above-mentioned information of each field may also be stored by associating a plurality of tables. In addition, it should be noted that the above-mentioned storage form of the remote access parameter includes, but is not limited to, via the database 303, and may also be stored via other forms, such as a disk file or other forms.
Specifically, there are multiple server nodes in the cluster 301, and the work content and the work process of the multiple server nodes are completely the same. In order to ensure the normal operation of the cluster 301 service, the server nodes need to be consistent. However, the individual server nodes occasionally change and are inconsistent with other server nodes, thereby affecting the normal operation of the entire cluster 301.
In order to ensure that each server node in the cluster 301 is consistent, each server node is remotely connected based on the remote access parameter, and the identification code of the configuration file of each server node in the cluster 301 is acquired and used for identifying whether the configuration file is abnormal or not, so that whether the corresponding server node is abnormal or not is reflected.
Optionally, the method for acquiring the identification code includes:
based on the remote access parameter, each server node in the cluster 301 is accessed based on a Secure Shell (SSH) method, and the identification code of the configuration file of each server node in the cluster 301 is acquired.

Then, during the operation of each server node in the cluster, the system files and/or application-related files of each server node may change, that is, the standard configuration files dynamically change along with the operation of the cluster. Thus, once the cluster initialization is complete, the dynamically changing profile may no longer be in the same state as the initialization, and the original standard profile becomes the profile during the post-initialization cluster operation in step 120.

meanwhile, on each server node of the cluster 301, based on a standard configuration file (a system file and/or an application program-related file) when each server node is initially configured, a unique MD5 code of the standard configuration file is generated, and the unique MD5 code is stored, for example, in the database 303;
then, the cluster 301 starts to work, and in the working process, each server node dynamically generates an MD5 code based on the current configuration file;
under the condition of starting the cluster system consistency detection method, the detection process comprises the following steps:
based on a multithread polling method and an SSH interaction-free method, the IP address, the port number, the user name and the password in the obtained remote access parameter list are used as remote access parameters to remotely connect each server node of the cluster 301;
