RabbitMQ系列之RabbitMQ集群

本文的集群是RabbitMq 自身的Cluster搭建 。

#hosts准备：

vim /etc/hosts
#172.16.3.79 s1
#172.16.3.105 s2     

172.16.2.10 centos-43
172.16.2.11 centos-44

#erlang cookie 设置

#path var/lib/rabbitmq/

chmod 755 .erlang.cookie
vi .erlang.cookie
cookie
chomd 600 .erlang.cookie

#打开EPMD 端口 4369

伪集群实例

一台机子启动两个Rabbitmq实例，分别指定不同端口和名称：

RABBITMQ_NODE_PORT=9991 RABBITMQ_NODENAME=rab /usr/local/rabbitmq/sbin/rabbitmq-server -detached
RABBITMQ_NODE_PORT=9992 RABBITMQ_NODENAME=rab2 /usr/local/rabbitmq/sbin/rabbitmq-server -detached
