如何在mongodb集群中添加碎片？

我在debian机器上设置了mongodb 3.2集群，配置如下

# Config Server - mongod.conf

storage:
  dbPath: /data/mongodb
  journal:
    enabled: true

systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

net:
  port: 27019
  bindIp: 0.0.0.0

replication:
 replSetName: rs0

sharding:
 clusterRole: "configsvr"


# Shard Server 1 - mongod.conf

storage:
  dbPath: /data/mongodb
  journal:
    enabled: true

systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

net:
  port: 27017
  bindIp: 0.0.0.0

replication:
 replSetName: rs0


# Shard Server 2 - mongod.conf

storage:
  dbPath: /data/mongodb
  journal:
    enabled: true

systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

net:
  port: 27017
  bindIp: 0.0.0.0

replication:
 replSetName: rs0

并运行mongos在查询路由器服务器上添加碎片

$）mongos--configdb mongo配置：27019

但我不能添加碎片

mongos> sh.addShard("rs0/mongo-db1:27017")
{
    "ok" : 0,
    "errmsg" : "Cannot add rs0/mongo-db1:27017 as a shard since it is part of a config server replica set",
    "code" : 96
}
mongos> sh.addShard("rs0/mongo-db1:27017")
{
    "ok" : 0,
    "errmsg" : "Surprised to discover that mongo-db1:27017 does not believe it is a config server",
    "code" : 72
}

getSharmap命令

mongos> db.runCommand("getShardMap");
{
    "map" : {
        "config" : "rs0/mongo-db1:27017,mongo-db2:27017",
        "mongo-db1:27017" : "rs0/mongo-db1:27017,mongo-db2:27017",
        "mongo-db2:27017" : "rs0/mongo-db1:27017,mongo-db2:27017",
        "rs0/mongo-config:27019" : "rs0/mongo-config:27019",
        "rs0/mongo-db1:27017,mongo-db2:27017" : "rs0/mongo-db1:27017,mongo-db2:27017"
    },
    "ok" : 1
}

这是mongos日志

2016-04-06T15:05:14.243+0000 I切分[Balancer]即将将元数据事件记录到操作日志：{u id:“mongo-router1-2016-04-06T15:05:14.243+0000-570525aa6b2b3378bb9daf56”，服务器：“mongo-router1”，客户端地址：，时间：新日期（1459955114243），内容：“Balancer.round”，ns:，详细信息：{executionTimeMillis:3，ErrorOccurd:true，errmsg:“无法从配置服务器获取更新的碎片列表，因为惊奇地发现mongo-db1:27017不相信它是配置服务器”}

我缺少什么。？

由于您尝试添加的碎片位于rs0副本集中，并且rs0持有您的配置服务器，因此它将不允许您创建碎片。请尝试将其添加到其他副本集中，如rs1，这样应该可以工作
