Preferably, the registration path of the brooker of the production state cluster at zk is/idmm/brooker.
Preferably, the registered path of the table of the production cluster above zk is idmm/table.
Preferably, the registration path of the brooker of the test state cluster above zk is/idmm/testnode/brooker.
Preferably, the registered path of the table of the test state cluster above zk is idmm/testnode/table.
Preferably, the production client obtains an address from an idmm/brooker path above zk and communicates with the server.
Preferably, the above-mentioned test state client obtains and communicates addresses from the idmm/testnode/brooker path above zk.
A zk-based message middleware online upgrading method comprises the following steps of:
step one: stopping the message middleware node, configuring the message middleware node into a test state node, and upgrading a node program;
step two: the producer and the consumer of the test are configured into a test state;
step three: performing service test of the upgrade node on pressure test;
step four: configuring the corresponding node into a production state;
step five: the above procedure is repeated until all nodes complete the replacement.
Compared with the prior art, the invention has the beneficial effects that:
after the zk-based message middleware online upgrading method and system provided by the invention are adopted, the test clusters of the message middleware are separated from the production clusters by using a load soft isolation mode, so that the online upgrading of the message middleware is realized, the verification of the clusters after the upgrading version is quickly realized, the assembly management mode is realized, the development is simple, and the later maintenance cost is low.
