I was just learning mongodb. I command I entered are :
use admin
db.shutdownServer();
This shutdown the database. After that whenever I'm writing mongo to start mongoDB it gives me :
MongoDB shell version: 3.0.12 connecting to: test

at (connect):1:6 at src/mongo/shell/mongo.js:179 exception: connect failed
When I run this : sudo service mongodb start
I get :
Redirecting to /bin/systemctl start mongodb.service Failed to start
mongodb.service: Unit mongodb.service failed to load: No such file or
directory.
I tried other different commands (even I've re installed it again) but none of them restarted mongodb.
How to start mongodb?
shut down the node
:SECONDARY> db.shutdownServer()
up
:~$ mongod --config /db/mongod-repl-2.conf
:SECONDARY> rs.slaveOk()
:SECONDARY> show dbs
admin 0.000GB
config 0.000GB
local 0.000GB
testDatabase 0.000GB
You need to fork your service again,
Try
mongod --dbpath /var/lib/mongo/ --fork --logpath /var/log/mongodb/mongod.log

This method only works if you want to repair your data files without preserving the original files
To find where you dbpath resides- vim /etc/mongodb.conf
check for option dbpath=
(I have dbpath=/var/lib/mongodb)
Default: /data/db/
Typical locations include: /srv/mongodb, /var/lib/mongodb or /opt/mongodb .
Replace the /var/lib/mongodb with your dbpath
sudo rm /var/lib/mongodb/mongod.lock
sudo mongod --dbpath /var/lib/mongodb/ --repair
sudo mongod --dbpath /var/lib/mongodb/ --journal
(Make sure that you leave you terminal running in which you have run above lines, dont press 'Ctrl+c' or quit it.) Type the command to start mongo now in another window.
Hope this works for you ! for those who want to repair your data files while preserving the original files mongo recover
I am unable to access mongo shell in Ubuntu 16.04, but am able to run
sudo mongod
and its working , but when i try to run
mongo or sudo mongo
the following error raises

Print the last line of cat /var/log/mongodb/mongod.log and the content of /etc/mongod.conf.
Ensure that in /etc/mongod.conf the dbPath exists, the port is correctly bind to 27017, host is 127.0.0.1
In addition try to remove the mongod socket file /tmp/mongodb-27017.sock
I am trying to connect to my mongo database in my remote server:
$ mongo xxx.xxx.xxx.xx:27017
But I get this error:

Any ideas why?
I even have tried to connect it with an username and password but it still fails to connect...
Run this following command :
sudo service mongodb stop
sudo rm /var/lib/mongodb/mongod.lock
sudo service mongod restart
mongo
sudo service mongodb start
Failed to start mongodb.service: Unit mongodb.service is masked.
What should I do? help me..

I think it's sudo service mongod start - please note the lack of b in mongod
I find the solution;
sudo mongod --dbpath /var/lib/mongodb/ --journal

my computer is Ubuntu 14.04 LTS and I am connecting to a server to run codes. I also use the mongo on this server. However, it suddenly closed and when I tried to connect to the mongo shell, it shows:
MongoDB shell version: 2.6.9
connecting to: test
2015-05-02T16:37:34.643+0200 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused

exception: connect failed
So should I restart mongo or should I restart the server? I use ps command to see all progresses on the server under my account, which is:
PID TTY TIME CMD
107018 pts/16 00:00:00 ps
233611 pts/16 00:00:00 bash
Does that mean that I cannot restart the server?
It seems mongodb suddenly shut down.
use sudo service mongodb restartto restart mongodb.
if it does not work and it is a test machine/personal computer ,
restart the machine is a good choice.
in addition,ps only shows your own process,sudo ps shows all process.
