Specify the database path explicitly like so  and see if that resolves the issue   mongod --dbpath data db

User · Answer

After installing the MongoDB you should manually create a data folder    By default MongoDB will store data in  data db   but it won t automatically create that directory  To create it  do     sudo mkdir -p  data db    sudo chown  id -u   data db  You can also tell MongoDB to use a different data directory  with the --dbpath option    For more detailed information go to MongoDB wiki page

You should create a startup bat if you re using Windows  much more convenient   C  mongodb mongodb-win32-x86 64-eiditon bin mongod exe --dbpath C  mongodb data   And just dbclick startup bat and mongodb will run using C  mongodb data as its data folder

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

Create the data db directory in your main  windows  partition   C   gt  mkdir  data C   gt  mkdir  data db   and then go to your mongo directory bin and run mongod exe   C   gt  cd  my mongo dir bin  C  my mongo dir bin gt  mongod   DON t CLOSE THIS WINDOW  Now in a different command prompt window run Mongo   C   gt  cd  my mongo dir bin C  my mongo dir bin gt  mongo    REMEMBER YOU HAVE TO KEEP THAT OTHER WINDOW OPEN   This solved the problem for me

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  gt  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 gt mkdir  data  C  Program Files MongoDB Server 3 6 bin gt mkdir  data db  C  Program Files MongoDB Server 3 6 bin gt 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 gt mongo    this will start your mongoDB client   Hope it helped     If it doesn t work  run CMD as an administrator

You just need to create directory in C   as C  data db   Now just start mongoDB   C  Users gi gupta gt  c  Program Files MongoDB Server 3 2 bin mongod exe  2016-05-03T10 49 30 412 0530 I CONTROL   main  Hotfix KB2731284 or later update is not installed  will zero-out data files 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  MongoDB starting   pid 7904 port 27017 dbpath C  data db  64-bit host GLTPM-W036 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  targetMinOS  Windows 7 Windows Server 2008 R2 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  db version v3 2 6 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  git version  05552b562c7a0b3143a729aaa0838e558dc49b25 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  OpenSSL version  OpenSSL 1 0 1p-fips 9 Jul 2015 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  allocator  tcmalloc 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  modules  none 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  build environment  2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten      distmod  2008plus-ssl 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten      distarch  x86 64 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten      target arch  x86 64 2016-05-03T10 49 30 414 0530 I CONTROL   initandlisten  options     2016-05-03T10 49 30 427 0530 I -         initandlisten  Detected data files in C  data db  created by the  wiredTiger  storage engine  so setting the active storage engine to 2016-05-03T10 49 30 429 0530 I STORAGE   initandlisten  wiredtiger open config  create cache size 1G session max 20000 eviction  threads max 4  config base false statistics  f chive true path journal compressor snappy  file manager  close idle time 100000  checkpoint  wait 60 log size 2GB  statistics log  wait 0   2016-05-03T10 49 30 998 0530 I NETWORK   HostnameCanonicalizationWorker  Starting hostname canonicalization worker 2016-05-03T10 49 30 998 0530 I FTDC      initandlisten  Initializing full-time diagnostic data capture with directory  C  data db diagnostic data  2016-05-03T10 49 31 000 0530 I NETWORK   initandlisten  waiting for connections on port 27017 2016-05-03T10 49 40 766 0530 I NETWORK   initandlisten  connection accepted from 127 0 0 1 57504  1  1 connection now open    It will then run as service in background

I think your log output states it clearly   exception in initAndListen  10296 dbpath   data db  does not exist  terminating   You may simply create this directory or better to define it as a configuration value within your configuration file then use it as mongod -f C  path to your mongodb conf

User · Answer

Also check if you have installed the Mongo as a windows service and if its running  That s also important  There might port conflict because of that

User · Answer

For Windows 7  You may specify an alternate path for  data db with the dbpath setting for mongod exe   as in the following example   c  mongodb bin mongod exe --dbpath c  mongodb data db   or   you can set dbpath through Configuration File

Check that path to database data files exists          Sun Nov 06 18 48 37  initandlisten  exception in initAndListen  10296   dbpath   data db  does not exist  terminating

If you re using Windows 7  7     Here is something you can try       Check if the installation is proper in CONTROL PANEL of your computer     Now goto the directory and where you ve install the MongoDB  Ideally  it would be in      C  Program Files MongoDB Server 3 6 bin   Then either in the command prompt or in the IDE s terminal  Navigate to the above path   Ideally your save file  and type      mongod --dbpath    It should work alright

User · Answer

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 gt mongod --dbpath   data db

User · Answer

mongod --dbpath  c   data db    run the above code  this will start the server
