我在localhost上创建了三个mongodb实例，其中包含不同的端口，如
mongod.exe --configsvr --dbpath C:\MongoDB2.6\mongodb\data --port 2021
mongod.exe --configsvr --dbpath D:\mongodb\data --port 2022
mongod.exe --configsvr --dbpath E:\mongodb\data --port 2023
这3个成功实例化。 现在我使用mongos命令对这三个实例进行clustring，我的命令就像这样
mongos.exe --configdb 127.0.0.1:2021,127.0.0.1:2022,127.0.0.1:2023
BUt它给了我这样的错误
C:\MongoDB2.6\bin>mongos.exe --configdb 127.0.0.1:2021,127.0.0.1:2022,127.0.0.1:2023 --port 2025

我没有得到我在做错的地方。在这个完整的例子中，实际上我正在尝试为mongodb实现分片。
现在我能够解决这个问题并试图执行shard命令
sh.addShard("127.0.0.1:2021,127.0.0.1:2022,127.0.0.1:2023")
现在它给了我错误
{
"ok" : 0,
"errmsg" : "can't use sync cluster as a shard. for replica set, have to use <setname>/<server1>,<server2>,..."
}
我不知道为什么会出现这个错误。
