Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In the embodiment of the invention, the high-level load balancing connection number strategy is used for providing DNS domain name resolution service, specified ip is returned for a domain name request of a client according to the strategy, and the ip with the minimum connection number is selected as a resolution result during the domain name resolution of the strategy and returned to a domain name requester for the client to use the ip connection storage service.
According to an aspect of the present invention, an embodiment of the present invention provides a method for updating a connection number based on load balancing, which may include, as shown in fig. 1, performing the following steps at a resolution node: s1, receiving a mounting request sent by the client; s2, analyzing the connection number information of each storage node, and determining the IP with the minimum connection number; s3, mounting the client to the IP with the least connection number; s4, updating the connection number corresponding to the IP with the least connection number in the connection number information.
The method disclosed by the invention is that after receiving the mounting request and returning the client IP, the domain name resolution node automatically adds one to the corresponding IP connection number, instead of updating after receiving the connection number information sent by the storage node, thereby enhancing the robustness and the availability of the connection number strategy. The more obvious the effect in the super-large cluster is, the more the balance value can be reflected.
In some embodiments, the method for updating the number of connections based on load balancing according to embodiments of the present invention may further include receiving connection number information of each IP sent by the storage node; and updating the connection number corresponding to the IP with the minimum connection number according to the received connection number information of each IP sent by the storage node.
Specifically, after a period of time, each storage node sends the acquired actual connection number information of each node to the domain name resolution node, and the domain name resolution node updates the connection number corresponding to the IP with the minimum connection number according to the actual connection number information.
Therefore, as long as the domain name resolution node receives the mounting request of the client, the number of the connections corresponding to the resolved IP is increased by one, and the problem that the number of the connections cannot be updated consistently when the DNS of the storage node fails and cannot send the number of the connections is avoided. However, the connection number information is not true statistical information but calculated, and has a certain error. For example, although the client is mounted to the IP with the minimum number of analyzed connections, the client may be removed soon, which may cause the number of connections recorded by the domain name resolution node to be incorrect, and then the number of connections of the IP may be updated by obtaining the actual number of connections sent by each storage node.
In some embodiments, after receiving the connection number information sent by each storage node, the corresponding connection number of other IPs may also be updated according to the received connection number information of each IP sent by the storage node.
In some embodiments, updating the connection number corresponding to the IP with the smallest connection number in the connection number information further includes:
judging whether a self-updating connection number switch is turned on or not;
responding to the opening of the switch, and adding one to the connection number corresponding to the IP with the minimum connection number in the connection number information;
and responding to the switch closing, and not changing the connection number corresponding to the IP with the minimum connection number according to the analysis result.
In some embodiments, the method further includes not changing the connection number corresponding to the IP with the minimum connection number according to the parsing result, and further includes:
and updating the connection number corresponding to the IP with the minimum connection number according to the received connection number information of each IP sent by the storage node.
Specifically, whether the self-updating connection number is started or not can be controlled through the self-updating connection number switch, if the switch is started, the connection number corresponding to the IP is increased after the domain name request connection number strategy analysis is finished, namely the IP with the minimum connection number is determined, if the switch is closed, the connection number corresponding to the analysis result IP is not adjusted after the domain name request analysis is finished, and the connection number information is updated only when the storage node corresponding to the IP sends the counted connection number information.
In some embodiments, after the high-level load balancing domain name resolution is successful, whether the optimized switch of the patent is turned on is judged, if the optimized switch is turned on, the number of NAS connections corresponding to the ip obtained by the resolution is increased by one, so that the situation that the number of connections of the node corresponding to the ip is abnormal in statistics, the information of the number of connections cannot be updated all the time, the number of the ip connections is always at the minimum value, the result is obtained by the resolution each time, the number of clients to which the ip is connected is excessive, and when the domain name resolution node receives the information of the number of connections sent by the storage node, the information of the number of the ip connections corresponding to the node is updated in time according to the actual information of the number of. If the switch is not turned on, the connection number information is not changed. When receiving the connection number information sent by the node in the step 2, the domain name resolution node updates the connection number information of the ip corresponding to the node in time according to the actual connection number information of the node.
In some embodiments, parsing the connection number information and determining the IP with the least number of connections further comprises:
and receiving the connection number information of each IP sent by the storage node.
Specifically, the connection number information collected and sent by the service program in each storage node may be received.
The method disclosed by the invention is that after receiving the mounting request and returning the client IP, the domain name resolution node automatically adds one to the corresponding IP connection number, instead of updating after receiving the connection number information sent by the storage node, thereby enhancing the robustness and the availability of the connection number strategy. The more obvious the effect in the super-large cluster is, the more the balance value can be reflected.

at least one processor 520; and
the memory 510, the memory 510 stores a computer program 511 that is executable on the processor, and the processor 520 executes the computer program to perform the steps of any of the above methods for updating the number of connections based on load balancing.
