MongoDB: replSet can't get local.system.replset config from self or any seed "server is not running with --replSet"
I try to setup a Replica Set on Ubuntu 14.04 x64. First error I run into when trying
$ sudo mongod --port 27017 --replSet rs0:
replSet can't get local.system.replset config from self or any seed (EMPTYCONFIG)
I read that > rs.initiate() solves that issue, so I do
$ sudo service mongod start
$ mongo
rs.initiate()
which throws:
{ "ok" : 0, "errmsg" : "server is not running with --replSet" }
So if I can't start mongod with --replSet how can I solve the error within rs.initiate() which I need to solve the first error?
It's like a vicious circle!
Answer
Solved the problem by using a second command shell:
console1:
$ sudo mongod --port 27017 --replSet rs0
console2:
$ mongo
> rs.initiate()
