when I do this:
sudo service mongodb start,
I get this error message:
Failed to start mongod.service: Unit mongod.service failed to load: No such file or directory.
So, I did this: mongod --version
I get this:
db version v2.6.3
2015-12-14T11:28:06.867+0500 git version: nogitversion
2015-12-14T11:28:06.867+0500 OpenSSL version: OpenSSL 1.0.1f 6 Jan 2014
I check the mongod status,I get this message:
mongodb.service - An object/document-oriented database
Loaded: loaded (/lib/systemd/system/mongodb.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since 一 2015-12-14 11:18:19 ORAT; 5min ago
Docs: man:mongod(1)
Process: 17923 ExecStart=/usr/bin/mongod --config /etc/mongodb.conf (code=exited, status=100)
Main PID: 17923 (code=exited, status=100)
I have used all kinds of methods which I can searched, but they don't work. Any help in this regard will be appreciated.
You should run
sudo service mongod start
not
sudo service mongodb start
Ensure that you install your MongoDB correcly. Well formed installation instruction provided on official MongoDB and on Digital Ocean.
Also verify that you correctly prepared mognodb to run, see Run MongoDB section on official site.
