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/node.js app running on MongoDB locally successfully, but upon restarting my computer, I attempted to restart the Mongo server and it began giving errors and wouldn't start. Since then, I have re-installed Mongo several times only to find the same error occurring. this is what I am receiving:
privee:mongodb-osx-x86_64-2.4.6 jonlinton$ ./bin/mongo
MongoDB shell version: 2.4.6
connecting to: test
Mon Aug 26 14:48:47.168 Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145
exception: connect failed
Am I missing a step? Should I be creating a config file? Some basic guidance would be really helpful. Thanks in advance for any insights.
If you have installed mongodb through homebrew
then you can simply start mongodb through (mongodb-community
if installted mongodb-community
brew services start mongodb
OR
brew services start mongodb-community
Then access the shell by
mongo
You can shut down your db by
brew services stop mongodb
You can restart your db by
brew services restart mongodb
For more options
brew info mongodb
Updated answer (9/2/2019):
Homebrew has removed mongodb formula from its core repository, see this pull request.
The new way to install mongodb using Homebrew is as follows:
~> brew tap mongodb/brew
~> brew install mongodb-community
After installation you can start the mongodb service by following the caveats:
~> brew info mongodb-community
mongodb/brew/mongodb-community: stable 4.2.0
High-performance, schema-free, document-oriented database
https://www.mongodb.com/
Not installed
From: https://github.com/mongodb/homebrew-brew/blob/master/Formula/mongodb-community.rb
==> Caveats
To have launchd start mongodb/brew/mongodb-community now and restart at login:
brew services start mongodb/brew/mongodb-community
Or, if you don't want/need a background service you can just run:
mongod --config /usr/local/etc/mongod.conf
Deprecated answer (8/27/2019):
I assume you are using Homebrew. You can see the additional information that you need using brew info $FORMULA
~> brew info mongo 255
mongodb: stable 2.4.6, devel 2.5.1
http://www.mongodb.org/
/usr/local/Cellar/mongodb/2.4.5-x86_64 (20 files, 287M) *
Built from source
From: https://github.com/mxcl/homebrew/commits/master/Library/Formula/mongodb.rb
==> Caveats
To reload mongodb after an upgrade:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Caveats is what you need to follow after installation.
Assuming you have created the data/db directory under bin after install.
<mongodb-install-directory>/bin
directoryRun the command
./mongod
Start a terminal for your mongo shell
<mongodb-install-directory>/bin
directoryRun the command (make sure you put the name of the database)
./mongo test
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.
