MongoDB best configuration for a Forum with more than 100k users and 200k topics.

Now I fixed the auth issue, but the problem remains with the command

 > MongoDB shell version: 2.6.5
 connecting to: test
 > use nodebb
 switched to db nodebb
 > db.auth('myuser','mypass')
 1
 > db.collection.totalIndexSize()
 > db.collection.stats()
{ "ok" : 0, "errmsg" : "Collection [nodebb.collection] not found." }

[andreapernici]

Ok. The problem was the .collection

> db.stats()
{
    "db" : "nodebb",
    "collections" : 5,
    "objects" : 10950579,
    "avgObjSize" : 559.5723418825617,
    "dataSize" : 6127641136,
    "storageSize" : 7159541760,
    "numExtents" : 28,
    "indexes" : 9,
    "indexSize" : 2563102416,
    "fileSize" : 10666115072,
    "nsSizeMB" : 16,
    "dataFileVersion" : {
            "major" : 4,
            "minor" : 6
    },
    "extentFreeList" : {
            "num" : 0,
            "totalSize" : 0
    },
    "ok" : 1
}

You can also run db.objects.stats() if I'm not mistaken.

The problem is on the Category cause I have a lot of them.

What about the other issue with the cluster=8?

Options not savings, a message appearing/disappear

For cluster to work properly you will need to configure redis for socket.io.

You can add a redis block into config.json with the default settings.

[andreapernici]

@baris mmm I'm using mongo.

I have to configure also redis together with mongo?

There is some more extensive docs about it specific to nodebb?

I found this https://github.com/deedw/mong.socket.io but it is already inside the nodebb packages or I have to install it and then put the configuration inside the nodebb config.json?

@andreapernici Officially, socket.io contains only an in-memory session adapter (which for obv. reasons won't work with a clustered setup), and a redis session adapter.

So if you're clustering w/ Mongo, you'll have to set up Redis alongside, and have both mongo and redis configuration hashes in your config.json

[andreapernici]

Ok. I understand.

I think it's correct. One of the thing I thought about NodeBB was that a good approach was to use Redis for notification etcetc and Mongo for the rest.

In this case to make a summary:

• install nodebb on Mongo.
• create a Redis instance.
• configure the json file with both mongo and redis references.

If you have some example feel free to share

Out of curiosity, why don't you use Redis? the new redis cluster feature let you shard data to multiple servers.
