In view of the above object, a first aspect of the embodiments of the present invention provides an embodiment of a method for thermal repair based on a RabbitMQ cluster. Fig. 1 is a schematic diagram illustrating an embodiment of a RabbitMQ cluster-based hot repair method provided by the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, creating a first node outside the RabbitMQ cluster, and setting the first node to be in a preset mode;
s2, starting a RabbitMQ service of the first node, adding the first node into a RabbitMQ cluster, and setting network link forwarding to forward a link accessing the RabbitMQ cluster to the first node;
s3, stopping the RabbitMQ service of all the nodes except the first node in the RabbitMQ cluster, deleting all the nodes and forming a new cluster by the deleted nodes; and
and S4, responding to the new cluster starting, switching the RabbitMQ service which is in interface with the first node from the first node to the new cluster, and deleting the network link forwarding and the first node.
The RabbitMQ is widely used and technically mature open source message middleware at present. The cluster service ensures the stability and reliability of the service and improves the throughput of the RabbitMQ. The RabbitMQ cluster is a cluster consisting of RabbitMQ services of a plurality of nodes and provides functions of high availability, load balancing and the like. The HA policy is a High availability (High availability) policy for RabbitMQ clusters to define synchronization and backup of node data in the cluster.
Fig. 2 is a schematic diagram illustrating connection of a RabbitMQ cluster and an external application in the prior art. As shown in fig. 2, cluster service nodes 1, 2 and 3 form a RabbitMQ cluster, and provide services to the outside through a VIP (virtual IP) for external applications to access the RabbitMQ services. The HA policy of the cluster service node can be modified instantly, and the queue (message queue in RabbitMQ), exchange (message exchange in RabbitMQ) and message entity after modification are synchronized and backed up according to the current policy. The VIP service of the cluster belongs to a polling mode to access cluster nodes. And the external application pushes and receives the message by accessing the RabbitMQ service port of the VIP.
The embodiment of the invention achieves the requirement of repairing the RabbitMQ cluster service by creating a new RabbitMQ service to replace the original RabbitMQ service and then switching the data flow direction.
And creating a first node outside the RabbitMQ cluster, and setting the first node to be in a preset mode. And a separate RabbitMQ node is created outside the RabbitMQ cluster, and the node needs to be set to a disk mode, so that the data can be migrated after other nodes stop. Disk mode refers to whether the RabbitMQ node can save backup data to Disk.
Starting the RabbitMQ service of the first node, adding the first node into the RabbitMQ cluster, and setting network link forwarding to forward the link accessing the RabbitMQ cluster to the first node. And adding the created RabbitMQ node into the original RabbitMQ cluster through a RabbitMQ command.

In some embodiments, said joining said first node to said RabbitMQ cluster further comprises: responding to the first node and other nodes in the RabbitMQ cluster under the same operating system, and configuring a different port number for the RabbitMQ service of the first node than the other nodes.
In some embodiments, said creating a first node outside of said RabbitMQ cluster comprises: configuring the same cache as other nodes in the RabbitMQ cluster.

As shown in fig. 3, a temporary service node (i.e., the first node) is created and added to the cluster service. And then adjusting the cluster HA strategy of the RabbitMQ, and synchronizing the current data to the temporary node service. The temporary service node may be started under the same operating system as the cluster service nodes 1, 2 and 3, or may be started under a different operating system. If the temporary service node and the cluster service nodes 1, 2 and 3 are in the same system, the socket port number of the RabbitMQ service needs to be configured, so that the service starting failure caused by the repeated port numbers is avoided. The temporary service node may be added to the cluster service via a RabbitMQ command, configuring the temporary service node with the same cache (cache) as the cluster service nodes 1, 2 and 3. The "same" here may be the same size or the same IP address. And cluster synchronization data consisting of the temporary service nodes and the cluster service nodes 1, 2 and 3 is set through an HA strategy.
In some embodiments, said setting network link forwarding to forward a link accessing the RabbitMQ cluster to the first node comprises: and forwarding ports of all nodes except the first node in the RabbitMQ cluster to the first node.
