How to stop mongo DB in one command

问题:

I need to be able to start/stop MongoDB on the cli. It is quite simple to start:

./mongod

But to stop mongo DB, I need to run open mongo shell first and then type two commands:

$ ./mongo

use admin

db.shutdownServer()

So I don't know how to stop mongo DB in one line. Any help?

回答1:

Starting and Stopping MongoDB is covered in the MongoDB manual. It explains the various options of stopping MongoDB through the shell, cli, drivers etc. It also details the risks of incorrectly stopping MongoDB (such as data corruption) and talks about the different kill signals.

Additionally, if you have installed MongoDB using a package manager for Ubuntu or Debian then you can stop mongodb (previously mongod) as follows:

• Upstart: sudo service mongodb stop

• Sysvinit: sudo /etc/init.d/mongodb stop

Or on Mac OS X

• Find PID of mongod process using $ top

• Kill the process by $ kill <PID> (the Mongo docs have more info on this)

Or on Red Hat based systems:

• service mongod stop

Or on Windows if you have installed as a service named MongoDB:

• net stop MongoDB

And if not installed as a service (as of Windows 7+) you can run:

• taskkill /f /im mongod.exe

If you literally want a one line equivalent to the commands in your original question, you could alias:

mongo --eval "db.getSiblingDB('admin').shutdownServer()"

Mark's answer on starting and stopping MongoDB via services is the more typical (and recommended) administrative approach.

回答3:

mongod --dbpath /path/to/your/db --shutdown

More info at official: http://docs.mongodb.org/manual/tutorial/manage-mongodb-processes/

回答4:

If the server is running as the foreground process in a terminal, this can be done by pressing

Ctrl-C

Another way to cleanly shut down a running server is to use the shutdown command,

> use admin
> db.shutdownServer();

Otherwise, a command like kill can be used to send the signal. If mongod has 10014 as its PID, the command would be

kill -2 10014

回答5:

I followed the official MongoDB documentation for stopping with signals. One of the following commands can be used (PID represents the Process ID of the mongod process):

kill PID

which sends signal 15 (SIGTERM), or

kill -2 PID

which sends signal 2 (SIGINT).

Warning from MongoDB documentation:
Never use kill -9 (i.e. SIGKILL) to terminate a mongod instance.

If you have more than one instance running or you don't care about the PID, you could use pkill to send the signal to all running mongod processes:

pkill mongod

or

pkill -2 mongod

or, much more safer, only to the processes belonging to you:

pkill -U $USER mongod

or

pkill -2 -U $USER mongod

PS
Note: I resorted to this option, because mongod --shutdown, although mentioned in the current MongoDB documentation, curiously doesn't work on my machine (macOS, mongodb v3.4.10, installed with homebrew):
Error parsing command line: unrecognised option '--shutdown'

PPS
(macOS specific) Before anyone wonders: no, I could not stop it with command
brew services stop mongodb
because I did not start it with
brew services start mongodb.
I had started mongod with a custom command line :-)

回答6:

Use mongod --shutdown

According to the official doc : manage-mongodb-processes/

:D

回答7:

One liners to start or stop mongodb service using command line;

1. To start the service use: NET START MONGODB
2. To stop the service use: NET STOP MONGODB

I use this myself, it does work.

回答8:

create a file called mongostop.bat

save the following code in it

 mongo admin --eval "db.shutdownServer()"

run the file mongostop.bat and you successfully have mongo stopped

回答9:

From the given commands I think you're on Linux.

Start MongoDB:

$ sudo service mongod start
mongod start/running, process XXXXX 

Check the Status:

$ sudo service mongod status
mongod start/running, process XXXXX 

Stop MongoDB:

$ sudo service mongod stop
mongod stop/waiting 

回答10:

I simply did:

quit();

Please note I'm using mongo 3.0.

I use this startup script on Ubuntu.

exit 0

回答14:

Windows

In PowerShell, it's: Stop-Service MongoDB

Then to start it again: Start-Service MongoDB

To verify whether it's started, run: net start | findstr MongoDB.

^{Note: Above assumes MongoDB is registered as a service.}

回答15:

Building on the answer from stennie:

mongo --eval "db.getSiblingDB('admin').shutdownServer();quit()"

I found that mongo was trying to reconnect to the db after the server shut down, which would cause a delay and error messages. Adding quit() after shutdown speeds it up and reduces the messages, but there is still one.

I also want to add context - I'm starting and stopping mongod as part of test cases for other code, so registering as a service does not fit the use case. I am hoping to end up with something that runs on all platforms (this tested in windows right now). I'm using mongod 3.6.9
