I'm newer to mongode, I use shell to start mongodb service but failed and get following error. What should I do?
mongod log

Try this. Open terminal, and at the prompt type:
sudo chown -R `id -un` /data/db
Exactly as written. This will give you write access to the /data/db directory which is what Mongo is complaining about. It should prompt you for your password. Once it does enter it and hit enter. After that, kill mongod, if running, and restart.
Make sure the MongoDB server (mongod) is listening on the right interface.
Listening on 127.0.0.1 (loopback interface) will only work locally. If you want to handle remote requests you will have to listen on a network interface that can be accessed remotely. Listening on 0.0.0.0 will listen on all network interfaces.
Step 1: Please check whether you have C:\data\db. If you dont have it create it manually.
Step 2: in command line go to directory of mongodb such as c:\Program files\Mongodb\server\3.4\bin and type *mongod
Step 3: type Mongo
Hopefully its gonna work out for you.

I followed the instructions listed here, https://docs.mongodb.com/manual/tutorial/install-mongodb-enterprise-on-red-hat/, and tried to install on a remote server from my local machine. I ssh from my local machine into the server and performed the steps for installation.
I'm not sure if there are additional steps that need to be completed or whether you have to set Directory Paths that are not the default ones since you are using a server instead of local machine. My current error is when I run mongo from my terminal and I get this error

sudo vim /etc/mongod.conf and setting bindIp: 0.0.0.0 did not work. Any help would be appreciated.

I get an error when I try to run mongo on the terminal.
I tried to reinstall and removed lock file and restarted it, but It still doesn't work. I am using AWS, is it some problem about inbound, outbound of network setting in AWS, Or any other problem?
Like the comments above, if you are trying to connect to a mongodb instance on the same host, using 127.0.0.1 it is a mongodb configuration problem, so, that is not possible to be any AWS Security Rules.
So, considering it is a mongodb problem, first try to repair it inside the host with:
sudo rm /var/lib/mongodb/mongod.lock
sudo mongod --repair
sudo service mongodb restart
sudo service mongod status
Refer: https://stackoverflow.com/a/29083477/8407784
After resolved the mongodb config problem, you need to test your connection from another host, setting /etc/mongod.conf - bind_ip = 0.0.0.0 (that means all interfaces), only for testing
Then you need to set your AWS Security Rules on the host instance allowing the external instance to access it on port 27017.
I am unable to access mongo shell in Ubuntu 16.04, but am able to run

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
sudo service mongodb start

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
different terminal is opening and
mongo
command is starting with
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.
