RabbitMQ集群搭建

RabbitMQ集群搭建

##CentOS7.2
##RabbitMQ 3.6.5

####所有节点运行 下面命令
cat >/etc/yum.repos.d/CentOS-OpenStack-liberty.repo <<EOF
[centos-openstack-liberty]
name=CentOS-7 - OpenStack liberty
baseurl=http://vault.centos.org/centos/7.3.1611/cloud/x86_64/openstack-liberty/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Centos-7
EOF
###
yum install -y rabbitmq-server

systemctl enable rabbitmq-server.service
systemctl restart rabbitmq-server.service

rabbitmqctl  add_user admin admin
rabbitmqctl  set_user_tags admin administrator

rabbitmqctl add_user openstack 123456
rabbitmqctl change_password openstack 123456
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
rabbitmqctl set_user_tags openstack administrator

rabbitmq-plugins list
rabbitmq-plugins enable rabbitmq_management
netstat -tnlp|grep beam


####所有节点执行命令  群集配置,/var/lib/rabbitmq/.erlang.cookie文件内容必须一致
echo $(echo 123456 |md5sum |cut -d ' ' -f1) >/var/lib/rabbitmq/.erlang.cookie
systemctl restart rabbitmq-server.service
netstat -tnlp|grep beam

########

######其它节点运行，主节点不用运行
rabbitmqctl stop_app
rabbitmqctl join_cluster rabbit@ops171
rabbitmqctl start_app
rabbitmqctl cluster_status

####此时 node2 与 node3 也会自动建立连接；如果要使用内存节点，则可以使用
####rabbitmqctl join_cluster --ram rabbit@ops232

#更改群集名称
###rabbitmqctl set_cluster_name RabbitMQ-Cluster

#查看群集状态
rabbitmqctl cluster_status
