如何将MongoDB副本集转换为独立服务器

问题描述

考虑一下，我有4个复制集，配置如下:

Consider, I have 4 replicate sets and the config is as follows:

{
 "_id": "rs_0",
 "version": 5,
 "members" : [
  {"_id": 1, "host": "127.0.0.1:27001"},
  {"_id": 2, "host": "127.0.0.1:27002"},
  {"_id": 3, "host": "127.0.0.1:27003"},
  {"_id": 4, "host": "127.0.0.1:27004"}
 ]
}

我可以使用mongo --port <port>

有些文档可在将独立副本转换为副本集，但是有人可以告诉我如何从副本集中转换回独立副本吗?

There are documents for getting information on Convert a Standalone to a Replica Set, but can anyone tell me how to convert back to standalone from replica set?

推荐答案

只需从副本集(rs.remove('host:port'))中删除主机，不使用replSet参数重新启动它即可，并且它又是独立的.

Just remove a host from replica set (rs.remove('host:port')), relaunch it without replSet parameter and it's standalone again.
