Mongodb won't start

I installed MongoDB using the Mac Homebrew command but when I run mongod

It's not recognized my my terminal :/

If I type in export PATH=$PATH:/usr/local/mongodb/bin then run mongod it starts up but quickly exits

mongod --help for help and startup options

I've tried restarting my shell but if I try to run mongod again, it comes back as unrecognised and requires me to retype in export PATH=$PATH:/usr/local/mongodb/bin.

It won't permit killing when you configured autostart so remove the lock file and repair it (mac osx).

 cd /data/db
 rm mongod.lock
 sudo mongod --repair

For any of the people who land up here, this was resolved (at least on my end) by stopping the already running mongodb service:

brew services stop mongodb

and then running mongod.

this solution work for me. I'm using mongodb version 3.2

i set path to,

/usr/local/bin

and i make mongodb data directory to /data/db and set permission to myown account. This tutorial from mkyong is really helpful.

Kyle: "It looks like mongo is already running or another process is using port 27017"

In this case, type the following command

ps wuax | grep mongo

You should see something that looks like this

User           31936   0.5 0.4 2719784 35624   ?? S     7:34pm   0:09.98 mongod
User           31945   0.0 0.0 2423368   184 s000 R+   8:24pm   0:00.00 grep mongo

Now enter the kill command for the mongod instance (31936 in this case):

kill 31936

I just installed brew on osx (10.9.3), mongod (2.6.1) and had the same problem. Def not running a second copy. 

$ lsof -i | grep 2701

shows no open port.

I found the following helped.

The default config file brew writes (/usr/local/etc/mongod.conf) contains the line:

bind_ip = 127.0.0.1,<my-machine>.local

If you edit this file and change the line to either of the following:

bind_ip = 127.0.0.1
or
bind_ip = <my-machine>.local

Then restart the service with the command below, it should startup as expected.

$ brew services restart mongodb

You can check for success or failure by tailing the logfile in another window while starting

$ tail -f /usr/local/var/log/mongodb/mongo.log

It appears it is trying to open both of the addresses listed here and they both resolve to 127.0.0.1 so we always get a failure when it tries to open the second port and then shuts the whole thing down.

For mongod not being in your PATH, it looks like the logic to support that was tweaked a couple of times since the version you're on. If you upgrade, that issue might well be fixed automatically.

As others have already said, the error it's giving indicates that another process is already using the configured port. One possibility is that in the past, you ran the command that Homebrew presented to you to install MongoDB as a LaunchAgent. If that's the case, this command should undo that, allowing you to launch it from the command-line.

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