Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, a home cloud platform is designed and constructed based on docker, and open source container deployment and management technologies generally used are kubernets, OpenStack and the like. The construction of the home cloud platform involves service discovery of physical nodes of the home cloud. However, automatic service discovery cannot be realized in this link, and especially for newly added physical nodes, the home cloud platform cannot read the newly added physical nodes normally, so that unreasonable scheduling of resources is caused, and user experience is poor.
Based on this, the method and the system for discovering the service of the physical node provided by the embodiment of the invention can improve the rationality of resource scheduling and improve user experience.
For the convenience of understanding the present embodiment, a detailed description is first given of the service discovery method of a physical node disclosed in the present embodiment.
The first embodiment is as follows:
fig. 1 is a flowchart of a service discovery method for a physical node according to an embodiment of the present invention.
Referring to fig. 1, the service discovery method of a physical node mainly includes the following steps:
step S01, when a new physical node joins the physical resource pool, the new physical node creates a corresponding message queue through the proxy service.
Specifically, when a new physical node joins the physical resource pool, the new physical node starts an agent service (agent), as shown in fig. 2 ((r)); the proxy service then creates a message queue for the corresponding physical machine on the rabbitMQ, as shown at (c). Each physical node corresponds to a message queue.
And step S02, each physical node reports heartbeat information and writes the heartbeat information into a physical machine resource list in the database.
In a specific implementation, the steps include the following:
firstly, the agent service sends heartbeat information to the PaaS layer according to the physical node. Each physical node reports heartbeat information to the Paas layer, and the heartbeat information comprises configuration information, load conditions and load information of the physical nodes.
And secondly, the PaaS layer formats the heartbeat information and then stores the heartbeat information into a redis cache in a database to generate a physical machine resource list. The PaaS layer organizes the load condition, the load information and the load policy of the physical node into json format information and stores the json format information in a redis cache of the database, as shown in fig. 2. After the above steps are completed, the resource scheduling node side of the Paas layer can read the newly added physical node, and in the next resource scheduling, the new physical node and the original physical node are jointly used as the selection object.
Further, step S02 includes: the PaaS layer sets expiration time for heartbeat information.
Step S03, the resource scheduling node in the PaaS layer selects a target message queue matching the service request information from all the message queues according to the physical machine resource list.
In a specific implementation, the method comprises the following steps:
firstly, the resource scheduling node obtains the load information of the physical node by reading the physical machine resource list. When the resource scheduling node selects a physical node, the resource scheduling node reads the physical machine resource list in the database, and further reads the load condition, the load information and the load strategy in the redis, as shown in the fourth step.
And secondly, selecting target load information matched with the service request information from the load information according to a scheduling algorithm and a screening strategy.
And thirdly, determining a target message queue in all message queues according to the target load information.
And fourthly, sending the service request information to a target message queue. And the PaaS layer sends the service request information to the corresponding target physical node through the target message queue.
In addition, regarding the expiration time set in step S02, when a certain physical node hangs up, the reported heartbeat information will fail after reaching the expiration time, and further the load information of the physical machine cannot be acquired, so that the resource scheduling node will not send the service request information to the message queue corresponding to the hung physical node.
Further, after step S02, the method for discovering the service of the physical node further includes:
and (3) editing the heartbeat information by mysql (relational database management system) in the database to obtain the physical equipment information of the physical nodes. Here, the heartbeat information is edited to obtain perfect physical device information.
Further, for the opposite process of adding a physical node newly, namely, the process of deleting a physical node, the above steps are reversed, but the operation of closing the physical node in the physical machine resource list is manually required.
Example two:
fig. 3 is a schematic diagram of a service discovery system of a physical node according to a second embodiment of the present invention.

Further, the heartbeat information reporting unit 200 includes:
the agent service sends heartbeat information to the PaaS layer according to the physical node;
and the PaaS layer formats the heartbeat information and then stores the heartbeat information into a redis cache in a database to generate a physical machine resource list.
