Abstract

Methods, apparatus and articles of manufacture to propagate node changes in a cluster of nodes and reconfigure services based on the node changes in a cloud computing environment are disclosed. Example methods disclosed herein include analyzing a node change event message at a first node of the plurality of nodes to identify a node change event type contained in the node change event message. The node change event type corresponds to a node change event experienced by a second node of the plurality of nodes. Example methods also include selecting, based on the node change event type, a script from a data storage installed in the first node, and reconfiguring, by executing the script at the first node, a service supported by the first node. Still further example methods, include broadcasting, to the plurality of nodes including the first node, the node change event message from the second node.

Claims

1. A first node of a cluster of nodes comprising:

a node change event server to identify a node change event type in an event message generated by a second node of the cluster of nodes, the event message indicating that a node change event corresponding to the node change event type was experienced by the second node; and

a script library containing a script folder corresponding to the node change event type, the script folder containing at least one script to be executed by the node change event server in response to the event message, the at least one script, when executed, to reconfigure a service supported by the first node.

2. The first node of claim 1, wherein the second node is implemented using a virtual appliance.

3. The first node of claim 1, wherein the at least one script, when executed, reconfigures the service to accommodate the node change event.

4. The first node of claim 1, wherein the node change event type is at least one of adding the second node to the cluster, removing the second node from the cluster, and promoting the second node to lead node.

5. The first node of claim 1, wherein the script folder is a first script folder and the at least one script is a first script, the script library further including a plurality of script folders, the script folders corresponding to respective node change event types and the script folders containing respective scripts.

6. The first node of claim 5, wherein the first script, when executed, causes the service to be shut down, reconfigured, and restarted.

7. The first node of claim 1, wherein the node change event server includes an event analyzer to analyze the event message to identify the node change event type and further identify at least one node identifier, the at least one node identifier identifying at least one of the second node, a lead node of the cluster, or replica nodes included in the cluster.

8. A method for propagating node change events to a plurality of nodes included in a cluster, the method comprising:

analyzing, by executing an instruction with a processor, a node change event message at a first node of the plurality of nodes to identify a node change event type contained in the node change event message, the node change event type corresponding to a node change event experienced by a second node of the plurality of nodes;

selecting, based on the node change event type, by executing an instruction with the processor, a script from a data storage installed in the first node; and

reconfiguring, by executing the script at the first node, a service supported by the first node.

9. The method as defined in claim 8, further including broadcasting, to the plurality of nodes including the first node, the node change event message from the second node of the plurality of nodes.

10. A method as defined in claim 8, wherein the node change event type is one of a node added event type, a node removed event type and a node promoted event type.

11. A method as defined in claim 8, wherein the service is a first service and the script is a first script, the method further including:

selecting, based on the node change event type, a script folder, from the data storage, the script folder containing the first script and a second script; and

reconfiguring, by executing the second script at the first node, a second service supported by the first node.

12. A method as defined in claim 8, wherein the reconfiguring of the service includes reconfiguring a first service component on the first node to enable communication with a second service component on the second node.

13. A method as defined in claim 9, wherein the second node generates and broadcasts the node change event message in response to experiencing the node change event.

14. A method as defined in claim 8, wherein the second node included in the plurality of nodes is implemented using a virtual appliance.

15. A tangible computer readable storage medium comprising computer readable instructions that, when executed, cause a first virtual appliance to at least:

analyze a node change event message to identify a node change event type contained in the node change event message, the node change event type corresponding to a node change event experienced on a second virtual appliance;

select, based on the node change event type, a script from a data storage installed in the first virtual appliance; and

reconfigure, by executing the script, a service supported by the first virtual appliance.

17. The tangible computer readable storage medium of claim 15, wherein the node change event type is one of a node added event type, a node removed event type and a node promoted event type.

18. The tangible computer readable storage medium of claim 15, wherein the service is a first service and the script is a first script, the instructions further to cause the first virtual appliance to:

select, based on the node change event type, a script folder, from the data storage, the script folder containing the first script and a second script; and

reconfigure, by executing the second script, a second service supported by the first virtual appliance.

19. The tangible computer readable storage medium of claim 15, wherein the instruction to reconfigure the service by executing the script includes reconfiguring a first component of the service installed on the first virtual appliance to operate with a second component of the service installed on the second virtual appliance.

20. The tangible computer readable storage medium of claim 15, wherein executing the script causes the service to stop operating on the first virtual appliance, to be reconfigured on the first virtual appliance, and to be restarted on the first virtual appliance.

16. The tangible computer readable storage medium of claim Error! Reference source not found., wherein the node change event message is supplied to the first virtual appliance by the second virtual appliance.
