rabbitmq cluster node operation

It is very important to delete data during the node recovery process, restore a single node, and then clear the data

Node addition:

1. rabbitmq-server -detached --- .erlang.cooike permission, 400 owner rabbitmq

2. rabbitmqctl stop_app

3. rabbitmqctl join_cluster --ram rabbit@rabbitmq1

4. rabbitmqctl start_app

5. rabbitmqctl  cluster_status

 

Node deletion

1.  rabbitmq-server -detached

Based on the above, the normal running mq node directly performs steps 2 and 3; 4 can be omitted or changed to rabbitmqctl stop

2. rabbitmqctl stop_app

3. rabbitmqctl reset 

4. rabbitmqctl start_app

 

Hard delete:

Directly delete a node in the cluster:

rabbitmqctl forget_cluster_node   node_name

 

By disc-->ram

1. Node delete rabbitmq-server -detached ---rabbitctl stop_app---- rabbitmqctl reset ((--2. Clear the original data (temporarily backup to other places) --rabbitmqctl join_cluster --ram rabbit@rabbitmq1 ---- -------- rabbitmqctl start_app))

2. Clear the original data (temporarily back up to other places)

3. Node increase

 

By disc-->ram

First restore to a single node, restart, clear data

add cluster
