And installing a database starting program and cloud storage service software on the main equipment and the standby equipment, and establishing communication connection with the corresponding server through a communication link so that the whole cloud storage service switching system can provide data storage, reading or downloading service for the client side subsequently. In this embodiment, the database starting program may be a program for starting a database, may also be referred to as a database instance, and is a process for accessing and using the database. The database may be a relational database such as Oracle, DB2, PostgreSQL, Microsoft SQL Server, Microsoft Access, MySQL, or Langchao K-DB; the database may also be non-relational data such as Redis, MongoDB, Neo4j, or the like. In this embodiment of the application, the cloud storage service software may be configured to be installed on one or more main devices and standby devices, and form a distributed storage cluster in combination with an ethernet network.
In this embodiment of the application, the reason for the downtime of the main device in S301 may be divided into multiple cases. Two situations are described below, one is that the master device crashes, and the other is that the master device needs routine maintenance and the cloud storage service is shut down by a technician. Based on the two types of host downtime, fig. 5 is a schematic flow diagram of a switching method of cloud storage services provided in the embodiment of the present application, where the method includes:
s501: the monitoring device sends a first request to the master device.
In this embodiment, the first request may be to check whether the communication link between the master device and the other device is operating normally. The monitoring device may send the first request to the master device in real time, and thus may detect immediately after the master device crashes. Or the first request is sent according to a preset time period. Alternatively, the first request may be a ping command.
S503: the monitoring device sends a second request to the master device.
In this embodiment of the application, the second request may be to detect whether the cloud storage service of the master device is normal. The monitoring device may send the second request to the master device in real time, and thus may detect immediately after the cloud storage service is turned off. Or sending the second request according to a preset time period.
S505: the monitoring device judges whether a first reply is received, wherein the first reply corresponds to the first request. If yes, go to S507; if not, go to S509.
In the embodiment of the application, if the monitoring device receives the first reply, it indicates that the communication link between the main device and the other device is normally operated, and the main device does not crash, otherwise, the main device crashes, and the main device is manually forcibly closed or the out-of-band system is utilized to close the main device.
S507: the monitoring device determines whether a second reply is received, wherein the second reply corresponds to the second request. If yes, the main device is not down and operates normally, and if not, the process goes to step S513.
S509: and the monitoring equipment sends a third request to the information backup equipment.
In this embodiment of the application, the entire cloud storage service switching system shown in fig. 4 further includes an information backup device, or the entire cloud storage service switching system includes an information backup module, and the information backup module may be built in the monitoring device or other devices, so as to prevent providing required startup parameter information for the monitoring device when the main device is down.
Optionally, the third request is used to request the device receiving the third request to send the startup parameter information to the monitoring device.
S511: the information backup device sends the starting parameter information to the monitoring device, and the process is ended.
In this embodiment of the application, the start parameter information may include a memory capacity of the first database, a data capacity of the cloud disk to be mounted, a position of the cloud disk to be mounted in the first database, and the like.
S513: the monitoring device sends a third request to the master device.
S515: and the main equipment sends the starting parameter information to the monitoring equipment.
In the embodiment of the present application, the information sent by the information backup device or the main device to the monitoring device may include, in addition to the start parameter information, client information of the main device service: the system comprises user identity information (user name: mobile phone number, micro signal, QQ number, mailbox and the like), password authentication information (character password, fingerprint password, voice password and the like) of a user, data disclosure willing indication information uploaded by a client and the like.
In this embodiment of the application, the operation sequence of S503 and S505 may be adjusted, and the monitoring device may first send the first request to the host device, and determine whether to send the second request to the host device according to whether the first reply is received. And if the primary device does not receive the first reply, sending a third request to the information backup device, and receiving starting parameter information returned by the information backup device, wherein in this case, the monitoring device does not need to send a second request to the primary device. If the main equipment receives the first reply, continuing to put a second request to the main equipment, and if the monitoring equipment receives the second reply, indicating that the main equipment is not down and still operates normally; if the second reply is not received, the fact that the main device cannot provide the cloud storage service is indicated, a third request needs to be sent to the main device, and the returned starting parameter information needs to be received.
S303: and the standby equipment mounts the cloud disk to be mounted according to the disk identification information of the cloud disk to be mounted, wherein the cloud disk to be mounted is positioned in the master database.
In this embodiment, the monitoring device may send a third control instruction to the first server corresponding to the master database, where the third control instruction carries the identity information of the standby device, and the first control instruction also carries the identity information of the first server corresponding to the master database. The first server establishes an ethernet communication link between the first server and the backup device based on the identity information of the first server.
In this embodiment of the application, since one cloud disk can only be mounted on one device, in an optional implementation manner, under the condition that the main device may send the first reply to the monitoring device and may not send the second reply to the monitoring device, the monitoring device may send the second control instruction to the main device, so that the main device unloads the cloud disk to be mounted, and preparation is made for subsequent standby devices to mount the cloud disk to be mounted. Optionally, the main device may disconnect the communication connection with the first server after the cloud disk to be mounted is unloaded, so that power consumption of the entire system may be saved.
In the embodiment of the application, only after the cloud disks are mounted on the main device and the standby device, the database starting program and the cloud storage service software can be installed on the main device and the standby device. Optionally, after the database startup program and the cloud storage service software are installed, the mounted cloud disk can be retained or unloaded according to the actual application condition.
In an optional real-time manner, before step S303 or before step S301, the standby device may unload the mounted placeholder cloud disk, disconnect the communication connection with the second server, and directly perform step S303 after receiving the first control instruction sent by the monitoring device, that is, the standby device mounts the cloud disk to be mounted according to the disk identification information of the cloud disk to be mounted.
In another optional embodiment, after the database startup program and the cloud storage service software are installed, the standby device does not uninstall the placeholder cloud disk, and the communication link with the second server is also normally connected. When the standby device is locally mounted with the cloud disk occupying place, the standby device replaces the disk identification information of the locally mounted cloud disk occupying place with the disk identification information of the cloud disk to be mounted based on the received disk identification information of the cloud disk to be mounted. Specifically, the standby device may locally locate a folder in which the disk identification information of the cloud disk occupying the space is located, and replace the disk identification information of the cloud disk occupying the space in the folder with the disk identification information of the cloud disk to be mounted.
And after the standby equipment replaces the disk identification information of the locally mounted occupation cloud disk with the disk identification information of the cloud disk to be mounted, the standby equipment unloads the occupation cloud disk. And after the standby equipment and the first server establish communication connection, mounting the cloud disk to be mounted. Therefore, before the standby equipment mounts the cloud disk to be mounted, the mounted space-occupying cloud disk is disguised as the cloud disk to be mounted, after the space-occupying cloud disk is unloaded, Automatic Storage Management (ASM) of the standby equipment can be directly started to mount the cloud disk to be mounted, and equipment switching is conveniently and quickly carried out.
Optionally, the standby device may disconnect the communication connection with the second server after uninstalling the placeholder cloud disk.
S305: and the standby equipment analyzes the starting parameter information according to the starting program of the main database corresponding to the program identification information.
In this embodiment, in an implementation manner that an optional standby device sets an ORACLE _ SID environment variable as program identification information of a primary database startup program, that is, a primary database instance name, in accordance with a primary database startup program, that is, system startup parameter information corresponding to the program identification information, the standby device uses the primary database instance to parse the startup parameter information, and creates an advertisement and a diagnostic dest directory.
In the embodiment of the present application, it is briefly described above that the database start-up programs are installed on both the main device and the standby device, and the main device and the standby device may be installed with the same database start-up program. Alternatively, the primary database startup program is only a name of the database startup program installed on the primary device, and receiving the program identification information of the primary database startup program means that the backup device can directly use the database startup program in the backup device to parse the startup parameter information.
Optionally, although the same database startup program is installed in the primary device and the backup device, the startup parameter information of different primary devices may be analyzed based on different program identification information and the database startup program in the backup device. Based on fig. 2, for example, two different main devices 202 and 204 exist in the entire system, where the main device 202, the main device 204, and the standby device are installed with the same database startup program, but the program identification information of the database startup programs of the main device 202 and the main device 204 are different, and if the main device 202 goes down, the monitoring device sends the startup parameter information of the main device 202 to the standby device 206, and the startup parameter of the main device 202 can be analyzed only if the standby device writes the program identification information of the main database startup program corresponding to the main device 202 into the database startup program of the standby device. Similarly, assuming that the main device 204 is down, the monitoring device sends the startup parameter information of the main device 204 to the standby device 206, and the startup parameter of the main device 204 may be analyzed only if the standby device writes the program identification information of the main database startup program corresponding to the main device 204 into the database startup program of the standby device. Therefore, the reliability of the whole switching process is ensured.
Optionally, although the same database startup program is installed in the main device and the standby device, in the actual application process, the database startup program in the main device that is normally used may be iterated. In order to ensure that the switched backup device uses the database startup program of the latest version, the program identification information includes the database startup program of the latest version. The standby equipment receives the program identification information, analyzes the program identification information to obtain the latest version of the database startup program and the version number of the latest version of the database startup program, determines the version number of the original database startup program in the standby equipment, and compares the version number of the database startup program with the version number of the latest version of the database startup program. If the comparison result is consistent, analyzing the starting parameter information by directly using the database starting program in the standby equipment, and if the comparison result is inconsistent, iterating the database starting program of the standby equipment according to the latest version of the database starting program and analyzing the starting parameter information based on the iterated database starting program.
