Starting and stopping mongod remotely

[Om]

Can I stop and start mongod server remotely?

I logged in remotely and tried executing

> use admin
> db.shutdownServer()

But is says

shutdownServer failed: unauthorized: this command must run from
localhost when running db without auth

How can I setup the auth so as to shutdown and restart the server
remotely?

You cannot restart it this way; you should use the host operating
system commands to start/stop the daemon/service.

But I need to stop and start it remotely. Is that possible? I want to replace a dead config servers. According to instructions on http://www.mongodb.org/display/DOCS/Changing+Config+Servers, I need to stop just one out of the remaining 2 config servers. Why is that? Why doesn't it say that we need to stop both so that config data doesn't change while we bring up a new config server. Does config data become read-only if one of the config servers goes down?

And for this purpose, I also want to know how to stop and start a config server remotely.

If you stop it what are you going to call to start it? You need to use
the operating system services to start the process via ssh or some
other remote service.

Yes, unless all config servers are up the config metadata is read-only.

Why do I need to stop just one config server (as it says on the page)? Why doesn't it mandate stopping both? Cause if only one is stopped, it is still possible that config database might get updated by the one config server that is running. Am I missing something? On the other hand, can I use mongodump which can go a same dump on a running mongo server?

If any config server is down the meta data goes read only.
So the others can't be updated if one is down.

Elliot,

 does it mean that there is no need to stop them while I do a dump of config data using mongodump?

A mongodump isn't safe in this case unless you are running with an
--master and use mongodump --oplog

Elliot,

 

  I was hoping that I don't have to start-stop the config server since I need to execute this process remotely and in a script. So I was hoping that I can do a mongodump and then restore that data to start a new config server. If the meta-data becomes read-only when a config server is down, why do I need to stop that server? That server won't be able to write to the config data anyway ... right?

If another config server is down - then a mongodump is safe.
