The default dbpath for mongodb is  data db   There is no default config file  so you will either need to specify this when starting mongod with    mongod --config  etc mongodb conf      or use a packaged install of MongoDB  such as for Redhat or Debian Ubuntu  which will include a config file path in the service definition   Note  to check the dbpath and command-line options for a running mongod  connect via the mongo shell and run   db serverCmdLineOpts     In particular  if a custom dbpath is set it will be the value of   db serverCmdLineOpts   parsed dbpath              MongoDB 2 4 and older db serverCmdLineOpts   parsed storage dbPath      MongoDB 2 6

I depends on the version and the distro   For example the default download pre-2 2 from the MongoDB site uses   data db but the Ubuntu install at one point used to use  var lib mongodb   I think these have been standardised now so that 2 2  will only use data db whether it comes from direct download on the site or from the repos

The Windows x64 installer shows the a path in the installer UI wizard    You can confirm which path it used later  by opening your mongod cfg file  My mongod cfg was located here C  Program Files MongoDB Server 4 0 bin mongod cfg  change for your version of MongoDB    When I opened my mongd cfg I found this line  showing the default db path   dbPath  C  Program Files MongoDB Server 4 0 data   However  this caused an error when trying to run mongod  which was still expecting to find C  data db   2019-05-05T09 32 36 084-0700 I STORAGE   initandlisten  exception in initAndListen  NonExistentPath  Data directory C  data db  not found   terminating  You could pass mongod a --dbpath     parameter  In my case   mongod --dbpath  C  Program Files MongoDB Server 4 0 data
