I'm trying to set up a a test environment on my pc including sharding. I've added 2 shardservers, a configsvr and a router instance. When i'm trying to add a shard I get following errormsg: "Can't use localhost as a shard since all shards need to communicate. Either use all shards and configdbs in localhost or all in actual IPs. host: localhost:27017 isLocalHost:1""
I searched online and I found a few topics about it but nowhere they explain how exactly and since I'm new to mongoDB it's quiet hard to understand what's going on. I looked here for example. But since I never used anything else than localhost I find it pretty weird.
This is how I set up:
2 shardsvr instances:
mongod --shardsvr --replSet rs1 --port 27017 --dbpath D:\data\db mongod --shardsvr --replSet rs2 --port 27018 --dbpath D:\data2\db
1 configsvr instance:
mongod --configsvr --replSet rs0 --port 27019 --dbpath D:\datacfg\db
I initialised the 3 replica sets (another question, do they need to be all different replicasets? or not?).
Then I added a mongos instance:
mongos --configdb rs0/localhost:27019 --port 27020
And then when I'm trying to connect to mongos & addshards it goes wrong:
mongo --port 27020
Since I'm never specifying a host I assume that he always uses localhost? no? I don't know how to check anyway. If you need more info tell me.
Thanks in advance
