Mail/ftp/web servers, on VIRTUAL!! dedicated server. Also resource usage. Centos 5.

Hi. First of all, would 4 or 5 websites, 1 ftp server (when downloading by someone or a few persons or one, concretize) and one mail server (not many emails, just to sound official and have a nice, spam-free email for myself). Websites with not that many, but some, later more visitors, quite high amount of images in some posts (a blog) eat much resources? Like CPU is ~1.8Ghz, maybe 1.6, Xeon, Rams are 1GB total. I'm not asking if it can run it, because i am using itfor other servers, i'm asking how much resources it would eat for each server?

Second of all, i could find guides for normal servers, dedicated ones, what about virtual dedicated servers? Please be sure what is a VDS though. So are there any tutorials for that? You cannot control a few things of this thing.

Also, can i use a few domains for those different websites and for the main computer, which wouldn't interract together? For example, you couldn't connect to the computer usign the domains, but you could connect trough the address given by your server provider, to be exat to a game server?

If you need a better explanation, please ask. Thank you for any answers to these questions.

Using Centos 5 and i would like to use the best software for those things available. I'm not very advanced linux user though, but i want the best software available anyway.

MONGOCONNECTIONEXCEPTION(3)						 1					       MONGOCONNECTIONEXCEPTION(3)

The MongoConnectionException class

INTRODUCTION

	Thrown when the driver fails to connect to the database.

	There are a number of possible error messages to help you diagnose the connection problem. These are:

	      o No  candidate  servers	found  Thrown when the driver cannot establish a connection to MongoDB (fulfilling the ReadPreferences, if
		specified).

	      o No server name given. This error occurs if you pass in "" as the server name, probably because of an typo with	string	interpola-
		tion, e.g., "$servr" instead of "$server".

	      o
		 failed to get host [hostname] or port [portnum] from [server].  This indicated that the server string was malformed. "[hostname]"
		and "[portnum]" will be as much as the driver could dicipher of it.

	      o Operation in progress Connecting to the database timed out.

	      o Transport endpoint is not connected Generally means that the connection string isn't correct, the driver couldn't  even  find  the
		database server.

	      o couldn't determine master No server in a replica set connection was identified as the primary.

	      o couldn't  get  host  info for [server] This indicated that DNS could not resolve the server address you gave. This could easily be
		caused by a typo, for example, "server" instead of "$server".

	      o Invalid Argument This can be caused by attempting to connect to a machine that is up but that the database isn't actually  running
		on. Make sure that you've started the database server before connecting.

	      o Permission  denied  This  means  that  the  socket could not be opened due to permissions issues. On Red Hat variants, this can be
		caused by a default setting that does not allow Apache to create network connections. You can override this setting by running:

	      $ /usr/sbin/setsebool -P httpd_can_network_connect 1

	If the error message is not listed above, it is probably an error from the C socket, and you can search the web for its usual cause.
