The invention provides a file processing method, device and system based on MongoDB and a server. The method includes: presetting a plurality of data document sets and at least one metadata document set in a MongoDB; after a to-be-stored file is received, detecting that the plurality of data document sets really do not store the to-be-stored file; storing preset attribute information based on theto-be-stored file into a corresponding data document set; updating the current metadata information of the to-be-stored file to a metadata document set. The metadata information is not stored in the memory of the Name Node, the technical problem that the mass small files cannot be stored due to the fact that a Name Node memory cannot store metadata information of the mass small files is solved, meanwhile, through classified storage of the files, storage of the large files can be achieved, and system level expansion can be conveniently achieved by adding a data file set.

The embodiment of the invention discloses a single sign on method and apparatus, a server and a storage medium. The method comprises the following steps: establishing a cache cluster, and integratingthe cluster in a single sign on server; receiving a target request parameter and a target single sign on verification code sent by a client; judging whether the target single sign on verification codeexists in the cache cluster; and if so, controlling page skipping according to the target request parameter. According to the single sign on method provided by the embodiment of the invention, by establishing the cache cluster, horizontal extension of the system can be achieved, and the single sign on verification code is stored in the cache cluster to improve the access speed of single sign on.

The invention discloses a storage cage with a variable volume. The key points of the technical scheme are that it includes a bottom plate and a cage body. The cage body includes a bottom surface and two pairs of sides. The two pairs of sides are respectively fixed sides and variable sides. The fixed hollow rod is set, and two sliding rods are arranged in the fixed hollow rod, and the two sliding rods protrude from both ends of the fixed hollow rod respectively, and the side parallel to the fixed hollow rod is a variable side, and the variable side includes There are several reinforcement rods perpendicular to the bottom surface. The variable side also includes multiple hollow adjustment rods set at equal distances and fixedly connected to the reinforcement rods. Both ends of the multi-channel hollow adjustment rods are aligned and parallel to the fixed hollow rods. Hollow adjustment Both ends of the rod are slidably connected with a volume expansion rod, and the volume expansion rod on the same side is opposite to the hollow adjustment rod and the end of the sliding rod on the same side opposite to the fixed hollow rod is fixedly connected to the fixed side. The invention has the advantage of realizing the lateral expansion of the storage cage.

The invention discloses a process management method based on multiple services, the multiple services are applied to multiple terminal devices, and the process management method comprises the following steps: obtaining task contents of all tasks, and creating a task table based on the task contents; generating a task relationship table of the task content and the process content based on the tasktable; acquiring a plurality of query instructions, and feeding back the task table and / or the task relationship table; obtaining at least one piece of competition information; managing the task relation table based on the at least one piece of competition information, and generating a corresponding management result; feeding back the management result. The invention further discloses a process competition method. By sharing the task content and the process content in the multiple devices and performing unified management, the multi-device management of the process is realized, the service fault risk caused by the fault of a certain device is effectively avoided, and the stable and reliable operation of the project is ensured.

According to the cloud storage management method, master-slave mode management is adopted, the storage capacity has expansibility, horizontal capacity expansion of a whole storage system can be achieved easily by setting the capacity of multiple data storage nodes and / or data of the data storage nodes, and mass data storage management can be achieved easily; and the hash modulus algorithm is a distributed strategy which is simple in principle and easy to implement, and the strategy has the greatest advantage of very excellent dispersity and can effectively ensure the load of the system.
