每个节点都必须标有区域属性——但如何标记？

Question

我在每个区域（2 个区域）中有 3 个节点，所有节点都列在 _membership 中。

[cluster]
q=3
r=2
w=2
n=3
z=2
placement = az1:3,az2:3

我无法使用 PUT/POST 命令来运行标记具有区域属性的节点。以下是来自文档：

First, each node must be labeled with a zone attribute. This defines which zone each node is in. You do this by editing the node’s document in the /nodes database, which is accessed through the “back-door” (5986) port. Add a key value pair of the form:

"zone": "metro-dc-a"

如有任何帮助，我将不胜感激。

Answer 1

文档的这一点4.4.4. Specifying database placement定义了设置节点区域的机制。

curl -X PUT http://localhost:5986/_nodes/<node-name> \
-d '{ \
    "_id": "<node-name>",
    "_rev": "<rev>",
    "zone": "<zone-name>"
    }'

每个节点都必须标有区域属性——但如何标记？

Each node must be labeled with a zone attribute - but how?
