Jack's questions

I've got something strange on my Apache2 server that is under Ubuntu Linux.

I've got two websites, one is directly handled by Apache2 through Passenger module (it's a ruby webapp), the other one is reverse proxied to another port to a Tomcat6 server.

Everything seems fine but Apache2 behaviour seems really greedy: with top I see that it has at least 5-6 processes and they grow up to 13-14 when I make some requests for just these two servers.

Is it correct to have so many processes?

Should I configure it to be less greedy if there's no need? I was making comparisons with a similar configuration on a less powerful machine (512mb RAM vs 2gb RAM) and it seems that on this machine it keeps less processes open. Maybe Apache2 benchmarks the machine to understand how many resources to allocate?

Just for info both machines are actually virtualized under VMWare server

Thanks in advance

I have a webserver tha actually has a tomcat6 server on port 80 and that is reachable from domain1.com. I would like to open another website on same machine using a sinatra (ruby) server and be able to reach it from domain2.com.

What should I do to achieve this? I suppose first move tomcat6 from 80 to another port and then place something local on 80 that tunnels to different webserver by using which domain the request came from.

But I really don't know how..

thanks in advance

which is the best way to allow a new user that I just created on ubuntu linux 9.04 to execute a script that requires some sudo without allowing him to the sudoers?

The fact is that I want to give the user just the ability to execute that script, without letting him to do anything more.

Is there a simple way to do it?

is it possible to easily set some users permissions on Linux? (actually my distro is Ubuntu server 9.04)

I mean:

• give them a maximum amount of space for their home folder
• restrincting the bandwidth that they can use
