[0035] figure 2 It is a schematic diagram of the architecture of the system for implementing database multi-path access provided in the first embodiment. see figure 2 , the system for implementing database multipath access in this embodiment may include a management server 210 , a database server 220 , a first NAT server 230 and a second NAT server 240 .

[0036] The management server 210 and the database server 220 are located at figure 1 In the cloud service environment network 110 shown, the first NAT server 230 is located in the first cloud network 250 , and the second NAT server 240 is located in the second cloud network 260 . Wherein, the first cloud network 250 may be one of the public cloud network and the private cloud network, the second cloud network 260 may be the other of the public cloud network and the private cloud network, or the first cloud network 250 and the second cloud network The network 260 may be two different public cloud networks, or the first c...

[0072] Figure 7 A schematic flowchart of a method for implementing multi-path access to a database provided for the second embodiment. see Figure 7 , the method for realizing database multi-path access in this embodiment may include the following steps:

[0073] Step S71, the management server sends an instance creation notification to the database server, so that the database server allocates database data storage space and creates a corresponding database instance.

[0074] The above instance application request refers to a request from a user to apply for a database service from an operator, and the instance application request includes a network identifier of the cloud network where the user is located, such as a network address, subnet mask, and the like. The above instance creation notification is used to notify the database server 220 to start the instance creation operation, and the instance creation notification includes the network identifier, so that the databas...

[0087] Figure 8 A schematic flowchart of a method for implementing multi-path access to a database provided by the third embodiment. see Figure 8 , the method for realizing database multi-path access in this embodiment may include the following steps:

[0088] Step S81, the management server sends an instance creation notification to the database server, so that the database server allocates database data storage space and creates a corresponding database instance.

[0089] Step S82, the management server sends a first network address translation notification to the first network address translation server, so that the first network address translation server creates a first access path pointing to the database instance.

[0090] The above steps S81 and S82 are respectively the same as the steps S71 and S72 in the second embodiment, and will not be repeated here.

[0091] Step S83, the management server generates and displays the instance application result according to t...

Abstract

The invention relates to a method, a device and a system for realizing database multipath access. The method can comprise the following steps that: a management server transmits an instance creating notification to a database server in a cloud service environment network after an instance application request is received; the database server allocates database data storage space and creates a database instance with a first network address and a first port; a network address conversion server of a first cloud network creates a second network address and a second port, and maps the second network address and the second port to the first network address and the first port in order to form a first access path; and a network address conversion server of a second cloud network creates a third network address and a third port, and maps the third network address and the third port to the first network address and the first port in order to form a second access path. Through adoption of the system, a plurality of paths for accessing the same database can be created, so that mutual access to databases between different networks is realized.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and system for realizing database multipath access. Background technique [0002] At present, the database server provides database services through the network address (IP) and port (Port). The single database service allocated by the operator to the user is called a database instance. A database instance has a certain network address and port. A certain network address and port connected to a database instance is called a single database access path. However, this method of accessing the database through a single path limits the database services provided by the database server to the same accessible network, such as a private cloud network or a public cloud network, that is, a database cannot be accessed by different servers at the same time. network access, when mutual access to databases is required between different cloud networks that are isolated from ...
