Installing and Running MongoDB on OSX

Question

If someone can provide some insights here I would GREATLY appreciate it.

I am new to MongoDB, and (relatively) new to the command line.

I had a express/nod

Answer 1

Problem here is you are trying to open a mongo shell without starting a mongo db which is listening to port 127.0.0.1:27017(deafault for mongo db) thats what the error is all about:

Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145 exception: connect failed

The easiest solution is to open the terminal and type

$ mongod --dbpath ~/data/db

Note: dbpath here is "Users/user" where data/db directories are created

i.e., you need to create directory data and sub directory db in your user folder. For e.g say `

/Users/johnny/data

After mongo db is up. Open another terminal in new window and type

$ mongo

it will open mongo shell with your mongo db connection opened in another terminal.

Mac Installation:

1. Install brew

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

2. Update and verify you are good with

   brew update
   brew doctor
   

3. Install mongodb with

   brew install mongodb
   

4. Create folder for mongo data files:

   mkdir -p /data/db
   

5. Set permissions

   sudo chown -R `id -un` /data/db
   

6. Open another terminal window & run and keep running a mongo server/daemon

   mongod
   

7. Return to previous terminal and run a mongodb shell to access data

   mongo
   

To quit each of these later:

1. The Shell:

   quit()
   

2. The Server

   ctrl-c
   

Answer 3

mongo => mongo-db console
mongodb => mongo-db server

If you're on Mac and looking for a easier way to start/stop your mongo-db server, then MongoDB Preference Pane is something that you should look into. With it, you start/stop your mongo-db instance via UI. Hope it helps!

Answer 4

For those that could be facing the same problem and the solutions suggested above aren't working, for example in my case, I had installed mongodb-community, so you might wanna run the command below to restart your mongo server.

For those that installed mongodb-community using brew

brew services start mongodb-community
