MongoDB (code=exited, status=14)

Hi, here is a quick tip if you get this annoying problem when you install MongoDB in linux.

When you start your MongoDB through:

service mongod start

and in result you got this error :

● mongod.service - MongoDB Database Server
   Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Fri 2019-08-23 05:33:57 UTC; 4s ago
     Docs: https://docs.mongodb.org/manual
  Process: 29284 ExecStart=/usr/bin/mongod $OPTIONS (code=exited, status=14)
  Process: 29281 ExecStartPre=/usr/bin/chmod 0755 /var/run/mongodb (code=exited, status=0/SUCCESS)
  Process: 29278 ExecStartPre=/usr/bin/chown mongod:mongod /var/run/mongodb (code=exited, status=0/SUCCESS)
  Process: 29276 ExecStartPre=/usr/bin/mkdir -p /var/run/mongodb (code=exited, status=0/SUCCESS)
 Main PID: 25199 (code=exited, status=0/SUCCESS)

this code problem means that your mongodb SOCK dont belong to mongodb user. So here is a quick fix :

1. Go to /tmp and find mongodb sock

cd /tmp; ls -l *.sock

2. Change the owner of that .sock file, it used to named as mongodb-27017.sock, but if you find it in a different name, its ok.

chown mongod:mongod mongodb-27017.sock

if the result come like this chown: invalid user: 'mongod:mongod' then it means that the user and group for mongodb was not mongod.

you can find the right username in the list of user in /etc/passwd file.
