how can I permanently change db path in Mongodb?

Question

I tried mongod --dbpath=/data option to change the data directory location, by executing this command continously running in forground waiting for connection

it works on mongo CLI, But after I stop the mongod --dbpath=/data by CTRL +C, mongo CLI refuse to Connect

Then After restarting mongod service, it's just normally use by default path in root directory.

Then I edited in /etc/mongodb.conf db path parameter, after mongob serive can't start

Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: 
   Active: failed (Result: exit-code) since Mon 2019-07-15 19:36:47 IST; 5s ago
     Docs: https://docs.mongodb.org/manual
  Process: 5355 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=exited
 Main PID: 5355 (code=exited, status=2)

How do I make this permanent

**I change that new directory ownership to mongodb user **I am using Ubuntu

Answer 1

Finally fixed that problem, I am actually put small case P in dbPath option. Then I properly give ownership that directory to mongodb user account, It works perfect!

Answer 2

change your init.d/mongodb script and make the following changes.I have used my own config ie. mongod1.conf. Make sure to change the ownership of the dbpath and log to mongodb
