Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, wherein it is apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the terms "comprises" and "comprising," along with their variants, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
A floating IP is typically a public IP address that is accessible to the internet and is not automatically assigned to entity devices (hosts, routers, load balancers, etc.), private addresses are used inside the private cloud, private addresses inside the private cloud cannot be routed to, and only services through entities within the floating IP can be identified and accessed by the external network, as well as traffic on the external network can only reach services inside the private cloud through the floating IP.
The floating IP is public network IP, a public network user enters Virtual Private Cloud (VPC) through the applied floating IP, the floating IP can be bound on a Virtual Machine (VM), a Bare Metal (BM), an elastic network card, an expansion network card, a HAVIP, a NAT gateway or Load Balancing (LB), and only an IPv4 address in the VNet has the floating IP and does not support the floating IP of IPv 6.
The main advantage of floating IP is flexibility, freedom of allocation as required. Floating IP is suitable for both fault recovery and service switching. The floating IP provides a unified IP to the outside, not an IP address actually providing a service to the outside.
The conventional floating IP allocation scheme is to obtain a corresponding floating IP from the mysql database when the target device requests to obtain the floating IP, and allocate the floating IP to the target device. However, since the mysql database is multi-threaded, when multiple target devices simultaneously request to acquire the floating IP, the floating IP allocation may fail, and meanwhile, the speed of acquiring the floating IP from the mysql database is slower, so that the efficiency and performance of allocating the floating IP by adopting the traditional floating IP allocation scheme are poor.
For example, in response to a request of the target device a and the target device B to randomly acquire the floating IP at the same time, the conventional floating IP allocation scheme may enable a double thread to pre-select the floating IP1 from the mysql database for both the target device a and the target device B, modify the allocation status of the floating IP1 in the mysql database, and if the thread corresponding to the target device a successfully modifies the allocation status of the floating IP1, and meanwhile, allocates the floating IP to the target device a, the thread corresponding to the target device B fails to modify the allocation status of the floating IP1, and meanwhile, the floating IP is allocated to the target device B for identification, that is, the target device B fails to acquire the floating IP this time.
In order to prevent the failure of the allocation of the floating IP in the conventional floating IP allocation scheme, in response to the simultaneous request of the target device a and the target device B to randomly acquire the floating IP, the target device B may also need to wait when the thread corresponding to the target device a acquires the floating IP in the IP set 1 and lock the IP set 1, until the target floating IP determined in the IP set 1 is successfully allocated to the target device a, the IP set 1 is unlocked and then the thread corresponding to the target device B can be started to acquire the floating IP in the IP set 1.
In order to improve efficiency and performance of allocation of floating IPs, the embodiments of the present application provide a method for allocation of floating IPs, where in response to an acquisition request of a target device, a target IP segment may be determined from each IP segment according to floating information corresponding to the acquisition request and segment information of each IP segment in a mysql database, and a corresponding target IP set is determined from a redis database according to the target IP segment, where the determined target IP set includes at least one floating IP in the target IP segment that is not allocated, and the target floating IP is acquired from the target IP set and allocated to the target device.
The following describes in detail the technical solutions provided in the embodiments of the present application with reference to the accompanying drawings.
The word "exemplary" is used hereinafter to mean "serving as an example, embodiment, or illustration. Any embodiment described as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
The embodiment of the application provides a floating IP allocation method, as shown in fig. 1, comprising the following steps:
Step S101, responding to an acquisition request of target equipment, and determining target IP fragments from the IP fragments according to floating information corresponding to the acquisition request and fragment information of the IP fragments in a mysql database.
The segment information may include the number of unassigned floating IPs in the corresponding IP segment, and the start floating IP and the end floating IP in the corresponding IP segment.
Specifically, if the floating information corresponding to the obtaining request is obtaining the unspecified floating IP, according to the number of the unassigned floating IP in the segment information of each IP segment, randomly selecting an IP segment including the unassigned floating IP from the mysql database as the target IP segment. For example, if the target device requests to randomly acquire a floating IP, an IP segment containing the available floating IP may be randomly selected from the IP segments in the mysql database, and if IP segment 1 is assumed, IP segment 1 may be used as the target IP segment.
If the floating information corresponding to the obtaining request is the obtaining of the specified floating IP, determining an IP segment containing the specified floating IP between the starting floating IP and the ending floating IP contained in the segment information from the mysql database, and taking the determined IP segment as a target IP segment. For example, assuming that the specified floating IP requested to be acquired by the target device is 50, and the starting floating IP included in the segment information of the IP segment 1 of the mysql database is 1 and the ending floating IP is 100, the target IP segment corresponding to the specified floating IP may be determined to be the IP segment 1 according to the starting floating IP and the ending floating IP included in the segment information of each IP segment of the mysql database.
If the floating information corresponding to the acquisition request is the floating IP in the designated IP segment, and the designated IP segment in the mysql database is determined to comprise the unassigned floating IP according to the unassigned floating IP number in the segment information of the designated IP segment, the designated IP segment is taken as the target IP segment. Assuming that the specified IP fragment requested to be acquired by the target device is IP fragment 1 and the number of unassigned floating IPs in the fragment information of IP fragment 1 of the mysql database is 60, IP fragment 1 may be directly taken as the target floating IP.
Step S102, according to the target IP segmentation, a corresponding target IP set is determined from the redis database.
Each IP segment in the mysql database corresponds to each IP set in the redis database one by one, and when the target IP segment is determined in the mysql database according to the acquisition request of the target device, the corresponding target IP set can be uniquely determined in the redis database according to the corresponding relation between the IP segment in the mysql database and the IP set in the redis database.
Step S103, obtaining the target floating IP from the target IP set, and distributing the target floating IP to the target equipment.
If the floating information corresponding to the acquisition request is that the floating IP is not specified to be acquired, one floating IP is randomly acquired from the target IP set to serve as the target floating IP. If the floating information corresponding to the acquisition request is the acquisition specified floating IP and the target IP set comprises the specified floating IP, the specified floating IP is used as the target floating IP.
The floating IP allocation method proposed by the embodiments of the present application may be applied in a plurality of available areas (Availability Zones, AZ). At least two AZs, and typically three AZs, may be included in a region to enable a customer to run production applications and databases with greater availability, fault tolerance, and extensibility. In a region-level deployment structure, floating IP allocations may be deployed at control nodes, while redis databases may be deployed at cache nodes.
In the floating IP allocation scheme proposed in the present application, the mysql database stores the segment information of the IP segment, the redis database stores the IP set containing the floating IPs, that is, the redis database stores each floating IP, and each floating IP is stored in a manner of an IP set corresponding to the IP segment. The floating IP allocation method in the present application is performed in the following manner:
when the target device requests to acquire the specified floating IP in the specified IP fragments, according to the specified IP fragments, inquiring whether available floating IP is included in the specified IP fragments in a mysql database, if so, inquiring an IP set corresponding to the specified IP fragments in a redis database, determining whether the IP set contains the specified floating IP, and if so, taking out the specified floating IP from the IP set, and distributing the specified floating IP to the target device;
When the target device requests to acquire the unspecified floating IP in the specified IP segment, according to the specified IP segment, inquiring whether available floating IP is included in the specified IP segment in a mysql database, if so, inquiring an IP set corresponding to the specified IP segment in a redis database, randomly taking out a floating IP from the IP set, and distributing the floating IP to the target device;
when the target device requests to acquire the specified floating IP in the unspecified IP fragments, according to the specified floating IP, searching an IP fragment containing the specified floating IP in a mysql database, determining whether the IP fragment contains an available floating IP, if the available floating IP is contained, searching an IP set corresponding to the IP fragment in a redis database, determining whether the specified floating IP is contained in the IP set, and if the specified floating IP is contained, extracting the specified floating IP from the IP set, and distributing the specified floating IP to the target device;
when the target device requests to obtain the unspecified floating IP in the unspecified IP fragments, it may first query the mysql database for an IP fragment including available floating IP, then query the redis database for an IP set corresponding to the IP fragment, randomly take out a floating IP from the IP set, and assign the floating IP to the target device.
Specifically, in one embodiment, the floating IP allocation method provided in the embodiment of the present application may also be implemented according to a procedure shown in fig. 2, as shown in fig. 2, including the following steps:
step S201, in response to the acquisition request of the target device, determining a request parameter corresponding to the acquisition request.
After receiving the acquisition request of the target device, the request parameter corresponding to the acquisition request can be determined, and the validity of the request parameter is verified.
Step S202, determining whether the request parameter contains a designated IP segment; if yes, go to step S203; if not, step S207 is performed.
Step S203, if it is determined that the specified IP segment includes the unassigned floating IP according to the unassigned floating IP number in the segment information of the specified IP segment in the mysql database, then the corresponding target IP set is determined from the redis database according to the specified IP segment.
Step S204, determining whether the specified IP segment in the request parameter contains the specified floating IP; if yes, go to step S205; if not, step S206 is performed.
In step S205, if the target IP set includes the specified floating IP, the specified floating IP is acquired from the target IP set, and is allocated to the target device.
Step S206, a floating IP is obtained from the target IP set randomly, and the floating IP is distributed to the target equipment.
Step S207, determining whether the request parameter contains a specified floating IP; if yes, go to step S208; if not, step S210 is performed.
Step S208, determining a target IP segment containing the specified floating IP between the starting floating IP and the ending floating IP from the mysql database.
Step S209, according to the target IP segmentation, a corresponding target IP set is determined from the redis database, if the target IP set comprises the specified floating IP, the specified floating IP is obtained from the target IP set, and the specified floating IP is distributed to the target equipment.
Step S210, randomly selecting a target IP segment comprising unassigned floating IP from the IP segments according to the unassigned floating IP number in the segment information of the IP segments in the mysql database.
