I have installed mongodb in my Ubuntu 10.04.

I know that when it comes to start the mongodb server with the command \"mongod\",then it expects /data/db

    Here is how I got this resolved, simply by following their official Doc . HERE.

    Step by step from teminal (running ubuntu) :

    1. cd into /srv folder =>> cd /srv/
    2. make directory =>> mkdir -p mongodb
    3. From within /srv/ give the newly created mongodb folder the right permissions and group ......
    4. Lastly, run this => mongod --dbpath /srv/mongodb/

    "step by step" Copy of the terminal ...... :)

     ~$ mongod

    Change the user of the new data directory:

    chown mongodb [rute_directory]

    And try another time to start the mongo service

    service mongodb start

    I solve the same problem with this.

    If you are using mac catalina:

    mongod --dbpath=/Users/user/data/db leave this window

    then you can type in another window.

    mongo

    show dbs

    1. Find mongo log file from root system folder

    sudo find / -name "mongodb.log" -type f

    result: /var/log/mongodb/mongodb.log

    1. open /var/log/mongodb/mongodb.log

    2. search for last "exception" word

    3. try to correct exception

    In my case exception was the next: 2015-07-30T15:09:15.806+0300 [initandlisten] exception in initAndListen: 13597 can't start without --journal enabled when journal/ files are present, terminating

    I made the next:

    1. cd /var/lib/mongodb
    2. rm -r journal/

    Assuming you have followed the instructions to install a packaged version of MongoDB, you should be starting and stopping mongod using service.

    To start mongod:

     sudo service mongodb start

    To stop mongod:

     sudo service mongodb stop

    If you use the service command to start and stop, it should be using the configuration file: /etc/mongodb.conf.

    Starting mongod from the command line

    If you run mongod directly instead of using the service definition, you will also have to specify a configuration file as a command line parameter if you want one to be used:

    mongod --config /etc/mongodb.conf
