For me the solution was to replace  service mongod start   with   start mongod

Try this   Write mongodb instead of mongod  sudo service mongodb status

User · Answer

This is a simple solution that worked for me with the same problem  I think    mv  var lib mongodb  var lib mongodb backup mkdir  var lib mongodb chmod 700  var lib mongodb chown mongodb daemon  var lib mongodb systemctl restart mongodb or service mongod restart

I think you may have installed the version of mongodb for the wrong system distro   Take a look at how to install mongodb for ubuntu and debian   http   docs mongodb org manual tutorial install-mongodb-on-debian  http   docs mongodb org manual tutorial install-mongodb-on-ubuntu   I had a similar problem  and what happened was that I was installing the ubuntu packages in debian

User · Answer

For debian  from the 10gen repo  between 2 4 x and 2 6 x  they renamed the init script  etc init d mongodb to  etc init d mongod  and the default config file from  etc mongodb conf to  etc mongod conf  and the PID and lock files from  mongodb  to  mongod  too  This made upgrading a pain  and I don t see it mentioned in their docs anywhere  Anyway  the solution is to remove the old  mongodb  versions   update-rc d -f mongodb remove rm  etc init d mongodb rm  var run mongodb pid diff -ur  etc mongodb conf  etc mongod conf   Now  look and see what config changes you need to keep  and put them in mongod conf   Then   rm  etc mongodb conf   Now you can   service mongod restart

I installed mongo server on Debian Jessie using manual from official site   It didn t started after recommended command  sudo service mongod restart with the same error - mongodb  unrecognized service   After looking into installed package contents  I noticed that it contains only Systemd service unit  but no SystemV init script     dpkg -L mongodb-org-server     usr  usr bin  usr bin mongod  usr share  usr share lintian  usr share lintian overrides  usr share lintian overrides mongodb-org-server  usr share doc  usr share doc mongodb-org-server  usr share doc mongodb-org-server LICENSE-Community txt  usr share doc mongodb-org-server README  usr share doc mongodb-org-server copyright  usr share doc mongodb-org-server changelog gz  usr share doc mongodb-org-server GNU-AGPL-3 0 gz  usr share doc mongodb-org-server THIRD-PARTY-NOTICES gz  usr share doc mongodb-org-server MPL-2 gz  usr share man  usr share man man1  usr share man man1 mongod 1 gz  etc  etc mongod conf  lib  lib systemd  lib systemd system  lib systemd system mongod service   But my system was running on SysV init     stat  proc 1 exe File    proc 1 exe  - gt    sbin init    So  there are 2 options now     Continue on SysV  Write sysV init script manually as  khylo mentioned above  Switch to SystemD  and run systemctl start mongod

For me nothing have helped  I ve ended up with a solution  create  lib systemd system mongod service file with content  Unit  Description High-performance  schema-free document-oriented database After network target Documentation https   docs mongodb org manual   Service  User mongodb Group mongodb ExecStart  usr bin mongod --quiet --config  etc mongod conf   Install  WantedBy multi-user target  then start stop commands should work   sudo service mongod start  For reference - I have Ubuntu 14 04 LTS  MongoDB 3 2 9 installed from deb http   repo mongodb org apt ubuntu trusty mongodb-org 3 2 multiverse

I got the same error one day You should use this   1 Get the status of your mongo service     etc init d mongod status   or   sudo service mongod status   2 If it s not started repair it like this   sudo rm  var lib mongodb mongod lock mongod --repair sudo service mongodb start   And  check again if the service is started again 1

You need to make sure the file  ex   etc init d mongodb  has execute permissions   chmod  x  etc init d mongodb
