RabbitMQ集群安装

首先参考上一篇文章【CentsOS原生RabbitMQ安装过程】在两到三台机器上先安装单独的RabbitMQ节点

修改一下hostname

1 2 3 4

[root@rnode1 ~]# vim /etc/hosts 172.16.20.110 rnode1 172.16.20.111 rnode2 172.16.20.112 rnode3

erlang节点之间通信需要相同的cookie文件，将其中一个机器上的cookie文件copy到另外两个机器

1 2	scp /var/lib/rabbitmq/.erlang.cookie rnode2:/var/lib/rabbitmq scp /var/lib/rabbitmq/.erlang.cookie rnode3:/var/lib/rabbitmq

首先在rnode1上观察一下节点状态如下

1 2 3 4 5 6 7

[root@rnode1 ~]# rabbitmqctl cluster_status Cluster status of node rabbit@rnode1 [{nodes,[{disc,[rabbit@rnode1]}]}, {running_nodes,[rabbit@rnode1]}, {cluster_name,<<"rabbit@rnode1">>}, {partitions,[]}, {alarms,[
