RabbitMq常用命令 - 一直到最后 - 博客园

安装rabbitmq

apt install rabbitmq-server -y   #3台主控

创建用户

rabbitmqctl add_user openstack ule.com

设置权限

rabbitmqctl set_permissions openstack ".*" ".*" ".*" 

rabbitmqctl set_user_tags openstack administrator

rabbitmqctl list_users

重启服务

systemctl enable rabbitmq-server
systemctl restart rabbitmq-server

端口：5672

主节点:192.168.2.30
子节点:192.168.2.31
子节点:192.168.2.32





授权
chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
chmod 400 /var/lib/rabbitmq/.erlang.cookie




验证
scp /var/lib/rabbitmq/.erlang.cookie 192.168.2.31:/var/lib/rabbitmq/   #将主的cookie拷贝到其他节点
scp /var/lib/rabbitmq/.erlang.cookie 192.168.2.32:/var/lib/rabbitmq/



以下操作在子节点
rabbitmqctl stop_app #停止集群

rabbitmqctl join_cluster --ram rabbit@controller30   #controller30主节点主机名

rabbitmqctl start_app #启动集群


 #查看集群状态
root@controller30:~# rabbitmqctl cluster_status
Cluster status of node rabbit@controller30
[{nodes,[{disc,[rabbit@controller30]},
         {ram,[rabbit@controller32,rabbit@controller31]}]},
 {running_nodes,[rabbit@controller31,rabbit@controller32,rabbit@controller30]},
 {cluster_name,<<"rabbit@controller30">>},
 {partitions,[]},
 {alarms,[{rabbit@controller31,[]},
          {rabbit@controller32,[]},
          {rabbit@controller30,[]}]}]



#配置rabbitmq的策略
rabbitmqctl set_policy ha-all '^(?!amq\.).*' '{"ha-mode": "all"}'

# 查看rabbitmq策略
root@2HD113Xrz25032:/etc# rabbitmqctl list_policies
Listing policies ...
/       ha-all  all     ^(?!amq\\.).*   {"ha-mode":"all"}       0





# 创建失败使用
# 主节点
systemctl stop rabbitmq-server
rabbitmqctl reset    #重置集群
systemctl start rabbitmq-server   
#rabbitmqctl reset
rabbitmqctl start_app

# 子节点
systemctl stop rabbitmq-server
rabbitmqctl reset         #重置集群
systemctl start rabbitmq-server
rabbitmqctl stop_app
rabbitmqctl join_cluster --ram rabbit@controller30
rabbitmqctl start_app


任意控制节点
rabbitmqctl cluster_status    

检查

root@controller:~/.ssh# rabbitmqctl cluster_status   #主节点查看集群状态
Cluster status of node rabbit@controller30
[{nodes,[{disc,[rabbit@controller30]},
         {ram,[rabbit@controller32,rabbit@controller31]}]},
 {running_nodes,[rabbit@controller32,rabbit@controller31,rabbit@controller30]},
 {cluster_name,<<"rabbit@controller30">>},
 {partitions,[]},
 {alarms,[{rabbit@controller32,[]},
          {rabbit@controller31,[]},
          {rabbit@controller30,[]}]}]
