MongoDB setup for Rocket.Chat error message

Question

I'm following this tutorial for a Rocket.Chat setup on an Ubuntu 14.04 LTS installation. After installation of Mongod, it says to setup a replica set and gives the instructions to insert the following at the end of /etc/mongod.conf:

replSet=001-rs 

However, when trying to initialize and create the replica set in the MongoDB shell with:

> rs.initiate() 

I'm greeted with this error message:

{ "info2" : "no configuration explicitly specified -- making one", "errmsg" : "exception: bad --replSet config string format is: <setname>[/<seedhost1>,<seedhost2>,...]", "code" : 13093, "ok" : 0 } 

Am I interpreting this to mean the mongod.conf line should read as something like:

replSet <name of set> 

Thanks in advance for any assistance.

Answer 1

the origin of your problem comes from the mongoDB service not started properly after you change.

It's a bit special under ubuntu...:-)

Create new file :

nano /etc/systemd/system/mongodb.service 

and write :

[Unit] Description=High-performance, schema-free document-oriented database After=network.target [Service] User=mongodb ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf [Install] WantedBy=multi-user.target 

now, use with :

sudo systemctl start mongodb # OR sudo systemctl stop mongodb
