What is the correct way to start a mongod service on linux / OS X?

I've installed mongodb and have been able to run it, work with it, do simple DB read / write type stuff. Now I'm trying to set up my Mac to run mongod as a service.

I get "Command not found" in response to:

 init mongod start

In response to:

~: service mongod start
service: This command still works, but it is deprecated. Please use launchctl(8) instead.
service: failed to start the 'mongod' service

And if I try:

~: launchctl start mongod
launchctl start error: No such process

So obviously I'm blundering around a bit. Next step seems to be typing in random characters until something works. The command which does work is: mongod --quiet & I'm not sure, maybe that is the way you're supposed to do it? Maybe I should just take off 'quiet mode' and add > /logs/mongo.log to the end of the command line?

I'm building a development environment on a Mac with the intention of doing the same thing on a linux server. I'm just not sure of the Bash commands. All the other searches I do with trying to pull up the answer give me advice for windows machines.

Perhaps someone knows the linux version of the commands?

Thanks very much

Edit: you should now use brew services start mongodb, as in Gergo's answer...

When you install/upgrade mongodb, brew will tell you what to do:

> To have launchd start mongodb at login:

    ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

> Then to load mongodb now:

    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

> Or, if you don't want/need launchctl, you can just run:

    mongod

It works perfectly.

With recent builds of mongodb community edition, this is straightforward.

When you install via brew, it tells you what exactly to do. There is no need to create a new launch control file.

$ brew install mongodb

==> Pouring mongodb-3.0.6.yosemite.bottle.tar.gz
==> Caveats
To have launchd start mongodb at login:
  ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
Then to load mongodb now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
  mongod --config /usr/local/etc/mongod.conf
==> Summary
🍺  /usr/local/Cellar/mongodb/3.0.6: 17 files, 159M

Homebrew's services tap integrates formulas with the launchctl manager. Adding it is easy:

brew tap homebrew/services

You can then launch MongoDB with this command (this will also start mongodb on boot):

brew services start mongodb

You can also use stop or restart:

brew services stop mongodb
brew services restart mongodb

If you feel like having a simple gui to fix this (as I do), then I can recommend the mongodb pref-pane. Description: https://www.mongodb.com/blog/post/macosx-preferences-pane-for-mongodb

Just installed MongoDB via Homebrew. At the end of the installation console, you can see an output as follows:

To start mongodb:

brew services start mongodb

Or, if you don't want/need a background service you can just run:

mongod --config /usr/local/etc/mongod.conf

So, brew services start mongodb, managed to run MongoDB as a service for me.

I did a bit of looking around on the Mac side. You may want to use the installer here as it looks like it does all the setup for you to automatically launch on Mac OS. The only downside is it looks like it's using a pretty old mongo version.

This link here also explains the setup to get mongo automatically launching as a background service on the Mac.

mongod --dbpath [path_to_data_directory]

First Step

install mongodb in your linux machine with

> apt install mongodb-client && apt install mongodb-server

second step is

change the database path instead of your system default path if you want.
so do the following steps and change it for yourself.

mongod --directoryperdb --dbpath /var/lib/mongodb/data/db --logpath /var/lib/mongodb/log/mongodb.log --logappend --rest

and in your windows machine do it just like that just put an --install flag. you have to get a successful message.

On macOS 10.13.6 with MongoDB 4.0

I was unable to connect to localhost from the mongo shell

I started MongoDB with:

> mongod --config /usr/local/etc/mongod.conf

I found that the 'mongod.conf' had:

> bindIp: 127.0.0.1

Change my JavaScript connection from localhost to 127.0.0.1 and it worked fine.

The same was occurring with MongoDB Compass too.

mongod wasn't working to start the daemon for me but after I ran the following, it started working:

'mongod --fork --logpath /var/log/mongodb.log'

(from here: https://docs.mongodb.com/manual/tutorial/manage-mongodb-processes/)

After installing mongodb through brew, run this to get it up and running:

mongod --dbpath /usr/local/var/mongodb
