The synchronization apparatus for the background configuration file according to this embodiment writes the configuration information into the relational database, generates a new configuration file in the local file system, and uploads the new configuration file to the file system, so that when a user accesses the configuration file from the configuration server through the application server, the configuration file can be searched from the local or from the file system or the configuration information can be searched from the relational database as needed, thereby dispersing access pressure and avoiding server avalanche phenomenon due to centralized management of data.
On the basis of the foregoing embodiment, a third embodiment of the present invention provides another synchronization method for a background configuration file, where the method is applicable to a configuration server, and for convenience of description, the method of this embodiment is described by dividing into two phases, namely synchronization configuration and access, and a non-relational database in the embodiment of the present invention is described by taking a no sql database as an example.
Referring to fig. 3, the method flow of the synchronization configuration phase includes:
s301, configuring relevant information in a configuration interface of a server and storing the configuration information;

s304, calculating a file feature code of the new configuration file;
s305, writing the file feature code into a key value appointed in a no sql database;
in practical application, the technical file feature code can prevent the configuration file from being tampered. The technical document feature code may be md 5.
S306, uploading the configuration file to a distributed file system;
in practical application, the authority control of the configuration file can be set in the step, and the leakage of the file can be prevented through the authority control.
In practical applications, both the relational database and the no sql database may be cluster type.
Referring to fig. 4, the access phase method flow includes:
s401, receiving an access request of a configuration file sent by an application server;

S404, searching the configuration file in the file system, if the configuration file is searched, executing the step S405, otherwise, executing the step S406.
In practical application, if the configuration file is set with the authority control, the file system will verify the authority of the visitor, and only when the authority of the visitor is allowed to access, the visitor is allowed to read the configuration file.
S405, writing the configuration file into the local file system.
S406, searching the configuration information corresponding to the configuration file from the relational database.
The method of the embodiment can process the abnormal condition to ensure high availability of the system, and the processing condition is as follows:
