docker swarm集群部署rabbit-mq

准备资料

1、rabbitmq.conf
2、init.d

1、rabbitmq.conf

default_vhost = /
default_user = admin
default_pass = admin
default_user_tags.administrator = true
default_permissions.configure = .*
default_permissions.read = .*
default_permissions.write = .*

2、init.d

1、master init

#!/bin/bash

chmod 777 /var/lib/rabbitmq/.erlang.cookie
cat /dev/null  > /var/lib/rabbitmq/.erlang.cookie
echo 'BDZXNSTIEMBUKJIQZRCX' >> /var/lib/rabbitmq/.erlang.cookie
chmod 400 /var/lib/rabbitmq/.erlang.cookie

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app

rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator

1、slave init

#!/bin/bash

chmod 777 /var/lib/rabbitmq/.erlang.cookie
cat /dev/null  > /var/lib/rabbitmq/.erlang.cookie
echo 'BDZXNSTIEMBUKJIQZRCX' >> /var/lib/rabbitmq/.erlang.cookie
chmod 400 /var/lib/rabbitmq/.erlang.cookie

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@rabbitmq-n1
rabbitmqctl join_cluster --ram rabbit@rabbitmq-n1
rabbitmqctl start_app

rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
