在配置文件中定义RabbitMQ策略

默认情况下，我想为所有队列定义镜像。节点启动后，我当前必须：

rabbitmqctl set_policy ha all”“{“ha mode”：“all”}

如果我的一个节点出现故障，我必须记住在重新启动时重新执行该代码

---

是否有方法自动配置我的节点以使用镜像队列？

无法在

rabbitmq.config

文件中设置策略。一种解决方法是使用init脚本启动rmq，并将

rabbitmqctl

命令放在其中，以便在rmq启动或重新启动时运行该命令。

可以在定义文件中指定策略，该文件可以从配置文件中引用

我如何设置特定策略的示例（不确定是否可以在策略中指定ha）：

/etc/rabbitmq/rabbitmq.config

[
{rabbit,
    [{vm_memory_high_watermark, 0.8}]
},
{rabbitmq_management,
    [{listener, [{port, 15672}]},
     {load_definitions, "/etc/rabbitmq/rabbitmq_definitions.json"},
     {http_log_dir, "/var/log/rabbitmq/management_http.log"}]
}
].

/etc/rabbitmq/rabbitmq_definitions.json

{       "users":[
            {"name":"rabbot","password_hash":"Cvse5iGOg20UqUq7Za9D1tatOJnMVDru4GHtxqc02g7zj5ur","tags":""},
            {"name":"rabnet","password_hash":"CqqG2fwvH6xz64NpibGJx2M7ZCyFnR1BQBM+C0KH2qRPmVxF","tags":"administrator"}],
    "vhosts":[
            {"name":"/"}],
    "permissions":[
            {"user":"viabot","vhost":"VIA","configure":".*","write":".*","read":".*"},
            {"user":"vianet","vhost":"VIA","configure":".*","write":".*","read":".*"}],
    "parameters":[],
    "policies":[
            {"vhost":"VIA","name":"DLX","pattern":".*","apply-to":"queues","definition":{"dead-letter-exchange":"dead_letter"},"priority":0}
            ],
    "queues":[
            {"name":"store_to_es","vhost":"VIA","durable":true,"auto_delete":false,"arguments":{}},
            {"name":"store_to_mongodb","vhost":"VIA","durable":true,"auto_delete":false,"arguments":{}}
            ],
    "exchanges":[
            {"name":"data_incoming","vhost":"VIA","type":"fanout","durable":true,"auto_delete":false,"internal":false,"arguments":{}},
            {"name":"sms_incoming","vhost":"VIA","type":"fanout","durable":true,"auto_delete":false,"internal":false,"arguments":{}}
            ],
    "bindings":[
            {"source":"data_incoming","vhost":"VIA","destination":"store_to_es","destination_type":"queue","routing_key":"","arguments":{}},
            {"source":"sms_incoming","vhost":"VIA","destination":"store_to_mongodb","destination_type":"queue","routing_key":"","arguments":{}}
    ]
}

我正在共享这个配置文件和定义文件，因为无法从RabbitMQ网站上找到它

注意：此配置在运行于Ubuntu 14.04的RabbitMQ 3.6.1上有效

要添加更多细节，我就是这样做的

首先：

sudo nano/etc/rabbitmq/rabbitmq.config

（此命令可能因操作系统而异）

重要提示：ha同步批大小仅在3.6.0以上的RabbitMQ版本中受支持！ 如果您的兔子年龄大于此值，请从

rabbitmq_definitions.json

中删除该设置

我正在使用Ubuntu14.04 Trusty和RabbitMQ v.3.6.2。

最后我发现了一些有用的东西： 不需要configMap或rabbitmq.config文件。 在

是的，您可以使用在重新启动时直接加载策略、队列、交换、绑定、用户等

预先设定你的兔子 转到

http://localhost:15672

Admin->Policies页，然后创建所需的新策略：

您还可以预先配置队列和其他内容

转储定义

curl-s-H“Accept:application/json”-u guest:guesthttp://localhost:15672/api/definitions >definitions.json

您还可以使用web界面转储定义。打开“概述”选项卡，向下滚动：

（！！！）更改

definitions.json

，以便只在重新启动时保留所需的内容

将有一节包含您的政策，保留它：

...
"policies": [
  {
    "vhost": "/",
    "name": "ha-all",
    "pattern": "",
    "apply-to": "all",
    "definition": {
      "ha-mode": "all"
    },
    "priority": 0
  }
]
...

重新启动时加载定义 将

definitions.json

放在兔子旁边，并将这一行添加到

rabbit.conf

。无需使用旧格式：

management.load_definitions = /path/to/definitions.json

以便在重新启动使用后加载某些内容

向@IvanD致敬，因为我的答案与之基本相同，但揭示了详细的步骤和新的配置格式用法。评论空间不足

...
"policies": [
  {
    "vhost": "/",
    "name": "ha-all",
    "pattern": "",
    "apply-to": "all",
    "definition": {
      "ha-mode": "all"
    },
    "priority": 0
  }
]
...

management.load_definitions = /path/to/definitions.json
