Then I tried

sudo service mongod start
sudo service mongod status

and it give me this fail error

I've tried deleted the socket file and give it a try but didn't work. Thank you in advanced! :)

Answer 1

I am not sure if this is the correct answer or not. However, it appears to me that

2017-05-29T01:17:58.469+0000 E NETWORK [initandlisten] Failed to unlink socket file /tmp/mongodb-27017.sock errno:1 Operation not permitted

is the main problem. Perhaps you could double check who owns this? also the permission?

It looks like this in my mongo:

Hopefully it helps

Answer 2

rm /var/lib/mongodb/mongod.lock
systemctl restart mongod
systemctl status mongod
