New to MongoDB Can not run command mongo

Question

I was trying to run MongoDB:

   E:\\mongo\\bin>mongod
    mongod --help for help and startup options
    Sun Nov 06 18:48:37
    Sun Nov 06 18:48:37 warning:          


        

Answer 1

This worked for me (if it applies that you also see the lock file):

first>youridhere@ubuntu:/var/lib/mongodb$ sudo service mongodb start 
then >youridhere@ubuntu:/var/lib/mongodb$ sudo rm mongod.lock*

Answer 2

Create the data/db directory in your main (windows) partition:

C:\> mkdir \data
C:\> mkdir \data\db

and then go to your mongo_directory/bin and run mongod.exe:

C:\> cd \my_mongo_dir\bin

C:\my_mongo_dir\bin> mongod

DON't CLOSE THIS WINDOW

Now in a different command prompt window run Mongo:

C:\> cd \my_mongo_dir\bin
C:\my_mongo_dir\bin> mongo

(REMEMBER YOU HAVE TO KEEP THAT OTHER WINDOW OPEN)

This solved the problem for me.

Answer 3

You just need to create directory in C:. as C:\data\db\

Now just start mongoDB:

C:\Users\gi.gupta>"c:\Program Files\MongoDB\Server\3.2\bin\mongod.exe"

It will then run as service in background.

Answer 4

create folder structure data/db in the working directory and then starting up mongodb using "mongod --dbpath data/db" works just fine

Answer 5

After several attempts this works for me on Windows 7 env.:

Initially directory to which you have copied all MongDB sources has such view:

bsondump.exe
mongo.exe
mongod.exe
mongod.pdb
mongodump.exe
mongoexport.exe
mongofiles.exe
mongoimport.exe
mongooplog.exe
mongoperf.exe
mongorestore.exe
mongos.exe
mongos.pdb
mongostat.exe
mongotop.exe

All you need is to add data directory and db directory nested( data/db ) Final view should look like this:

data
bsondump.exe
mongo.exe
mongod.exe
mongod.pdb
mongodump.exe
mongoexport.exe
mongofiles.exe
mongoimport.exe
mongooplog.exe
mongoperf.exe
mongorestore.exe
mongos.exe
mongos.pdb
mongostat.exe
mongotop.exe

Than simply type in directory where MongoDB sources and data/db dirs exist this command:

C:\my_mongo_dir\bin>mongod --dbpath .\data\db

Answer 6

The very simplest approach given by mongo README help file

RUNNING

For command line options invoke:

$ ./mongod --help

To run a single server database:

$ sudo mkdir -p /data/db
$ ./mongod
$
$ # The mongo javascript shell connects to localhost and test database by default:
$ ./mongo
> help

If you are working with windows, go to your directory where you have mongo.exe

use the following commands, (I am sharing mine)

C:\Program Files\MongoDB\Server\3.6\bin>mkdir \data

C:\Program Files\MongoDB\Server\3.6\bin>mkdir \data\db

C:\Program Files\MongoDB\Server\3.6\bin>mongod ## this will start your mongoDB server

Now you need to run another CMD prompt and go to the directory where you have mongo and just run it

C:\Program Files\MongoDB\Server\3.6\bin>mongo ## this will start your mongoDB client

Hope it helped :)

If it doesn't work, run CMD as an administrator
