    //创建vhost
    [wisdom@rabbitmq188 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl add_vhost /zabbix  

    //删除vhost
    [wisdom@rabbitmq188 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl delete_vhost /zabbix


    * 用户管理
    //创建用户
    [wisdom@localhost ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl add_user xroot xroot123

    //查看用户列表
    [wisdom@localhost ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl list_users


    * 用户角色管理
      1. 超级管理员(administrator)
         可登陆管理控制台(启用management plugin的情况下),可查看所有的信息,并且可以对用户,策略(policy)进行操作
      2. 监控者(monitoring)
         可登陆管理控制台(启用management plugin的情况下),同时可以查看rabbitmq节点的相关信息(进程数,内存使用情况,磁盘使用情况等)
      3. 策略制定者(policymaker)
         可登陆管理控制台(启用management plugin的情况下),同时可以对policy进行管理.但无法查看节点的相关信息(上图红框标识的部分)
      4. 普通管理者(management)
         仅可登陆管理控制台(启用management plugin的情况下),无法看到节点信息,也无法对策略进行管理
      5. 其他
         无法登陆管理控制台,通常就是普通的生产者和消费者

    //修改用户角色
    [wisdom@localhost ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl set_user_tags xroot administrator


    * 用户权限
    //查看指定vhost权限
    [wisdom@rabbitmq188 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl list_permissions -p /

    //查看指定用户权限
    [wisdom@localhost ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl list_user_permissions  xroot

    //为用户设置权限
    [wisdom@localhost ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl set_permissions -p / xnroot '.*' '.*' '.*'

    //清空所有权限
    [wisdom@localhost ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl clear_permissions

    //将229 Rabbit加入到228集群中
    [wisdom@rabbit229 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl join_cluster rabbit@rabbit228

    //启动229 Rabbit服务
    [wisdom@rabbit229 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl start_app

    //查看集群状态
    [wisdom@rabbit229 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl -n rabbit@rabbit228 cluster_status
    Cluster status of node rabbit@rabbit228 ...
    [{nodes,[{disc,[rabbit@rabbit228,rabbit@rabbit229]}]},
     {running_nodes,[rabbit@rabbit228]},
     {cluster_name,<<"rabbit@rabbit228">>},
     {partitions,[]},
     {alarms,[{rabbit@rabbit228,[]}]}]

  9. RabbitMQ 集群操作: 将230 RabbitMQ加入到228 RabbitMQ集群中(内存存储)

    //清空230 Rabbit元数据
    [wisdom@rabbit230 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl -n rabbit@rabbit230 reset

    //将230 Rabbit加入到228集群中,内存存储
    [wisdom@rabbit230 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl join_cluster rabbit@rabbit228 --ram

    //启动230 Rabbit服务
    [wisdom@rabbit230 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl start_app

    ////查看集群状态
    [wisdom@rabbit229 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl -n rabbit@rabbit228 cluster_status
    Cluster status of node rabbit@rabbit228 ...
    [{nodes,[{disc,[rabbit@rabbit228,rabbit@rabbit229]},{ram,[rabbit@rabbit230]}]},
     {running_nodes,[rabbit@rabbit230,rabbit@rabbit229,rabbit@rabbit228]},
     {cluster_name,<<"rabbit@rabbit228">>},
     {partitions,[]},
     {alarms,[{rabbit@rabbit230,[]},{rabbit@rabbit229,[]},{rabbit@rabbit228,[]}]}]

  10. 设置集群中所有的队列为镜像队列(任意一台机器上执行)

    1
    [wisdom@rabbit228 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'

  11. 设置用户权限

    [wisdom@rabbit228 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl add_user test test123  
    [wisdom@rabbit229 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl set_user_tags test administrator
    [wisdom@rabbit228 ~]$ /mnt/app/rabbitmq/sbin/rabbitmqctl set_permissions -p / test ".\*" ".\*" ".\*"

  12. 安装haproxy,作为反向代理
