【问题描述】：

尝试从头开始设置 MongoDB 副本集时，我感到非常沮丧。我有 2 台机器运行 debian os 并安装了 mongodb。当我尝试使用 rs.add() 将成员添加到副本集时，虽然我仍然通过

连接到 mongodb，但出现错误

mongo --host 13.212.31.212:27017

这里是错误信息

rs0:PRIMARY> rs.add("13.212.31.212:27017")
{
    "operationTime" : Timestamp(1597144435, 1),
    "ok" : 0,
    "errmsg" : "Quorum check failed because not enough voting nodes responded; required 2 but only the following 1 voting nodes responded: 192.168.0.59:27017; the following nodes did not respond affirmatively: 13.212.31.212:27017 failed with Received heartbeat from member with the same member ID as ourself: 0",
    "code" : 74,
    "codeName" : "NodeNotFound",
    "$clusterTime" : {
            "clusterTime" : Timestamp(1597144440, 1),
            "signature" : {
                    "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
                    "keyId" : NumberLong(0)
            }
    }
}

这里是 mongod conf

# Where and how to store data.
storage:
dbPath: /var/lib/mongodb
journal:

#  engine:
#  mmapv1:
#  wiredTiger:

# where to write logging data.
systemLog:

logAppend: true
path: /var/log/mongodb/mongod.log

# network interfaces

port: 27017
bindIp: 127.0.0.1,172.26.2.229


# how the process runs
processManagement:

我做错了什么？

【问题讨论】：

根据这个类似的问题和答案stackoverflow.com/a/41969210/788223 这个错误可能是因为 rs.initiate() 在两个节点上运行（您只需要在主节点上运行它）或您所在的节点在其 db 路径中添加已有数据。
为什么在各个地方都提到了两个私有IP范围和一个公共IP范围？

【解决方案1】：

这是描述性错误消息：

以下1个投票节点响应：192.168.0.59:27017；以下节点未肯定响应：13.212.31.212:27017 failed with Received heartbeat from member with the same member ID as ourself: 0"

那就是告诉你192.168.0.59:27017和13.212.31.212:27017是同一个节点，不能重复添加同一个节点。
