集群搭建

#设置 erlang cookie 一致性

cd /var/lib/rabbitmq/
vim .erlang.cookie 
#将所有服务器上设置一致的

 

#修改权限

# 修改用户组
chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie

# 仅只有所有者可读
chmod 400 /var/lib/rabbitmq/.erlang.cookie

 

#修改hostname

vim /etc/hosts
# master
172.*.*.2   app1 

#slave
172.*.*.3   app2 

 

#修改主机名

#修改主机名( master )
hostnamectl set-hostname app1

#修改主机名( slave)
hostnamectl set-hostname app2

 

#修改节点名称

vim /etc/rabbitmq/rabbitmq.conf
#master 使用这行
NODENAME=rabbit@app1 

#slave 使用这行
#NODENAME=rabbit@app2

 

slave 设置 cluster 节点

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@app1
rabbitmqctl start_app
