Question

Installing ubuntu 9.04 and LAMP and Railo and Webmin

Asked by: COwebmaster

I'm having a new server built with an Intel motherboard and 2 Intel 64 bit quad core xeon processors.  It will have RAID 1+0, dual power supply and 1GB ethernet nic+1 and 8GB or RAM (up to 32GB capacity).  This 2U rack server will serve up cfm and php web pages and will sit in a nice and cool co-location facility.

The thought was to install windows server 2008 but the licensing is a deterrent to me.  I've decided to install the latest version of ubuntu server 9.04 and ubuntu desktop.

Questions:

1) Is my server hardware overkill for a linux debian kernal install?
2) What is your opinion on installing ubuntu 9.04 on a Intel motherboard?
3) Have you had any issues installing Railo on ubuntu 9.04?
4) Have you had any issues installing Webmin on ubuntu 9.04?
5) Do I need to install Resin if I install Railo?
6) Have you experienced http error 500 errors using ubuntu?
7) How does ubuntu handle RAID?
8) How often would I have to upgrade ubuntu?
9) How secure is ubuntu and what types of hardware and/or software firewalls would you suggest?
10) Does it makes sense to have a proxy server set up for added security?  If so, what would that look like?

1&2: No.Just make sure you use the 64 bit version of Ubuntu, and why the desktop?

3. What is railo? Never heard of that.

4. No problem with Webmin.

5. What is resin? Never heard of that.

6. Don't know, as I don't do webhosting.

7. If you use a good Hardware RAID Controller to which Ubuntu has a driver, the OS doesn't handle RAID but rather the controller and it's utility Software. If you use a softraid controller, then don't use the controller's RAID setup, but rather use Linux's software DMRAID, that works well, much better than m$'s software RAID.

8. Depends on the Version. Ubuntu's LTS version (Long Term Support), ie Ubuntu 8.04 LTS is maintained until 2013, while the 9.04 version until next year. This, though, usually isn't a problem, as upgrades work seamlessly through the package manager, and are almost as simple as running the day-to-day updates. An advantage with linux updates and upgrades when compared with m$ OS's is that the complete system is updated, not just the OS, as long as you don't have anything installed that isn't supplied through the distribution's or 3rd party repositories through the package manager.

9. Depends how you use it and what you install. A standard Server installation is very secure, if you add a Desktop GUI you can loose some security. It has a built-in firewall based on iptables, very secure.

10. Squid is the proxy server you would normally use in Linux, but it would only be really useful if you have internal PC's. It would also provide caching which would make access to already used external sites faster.

I would install destop to give me a gui.

 

by: COwebmasterPosted on 2009-08-19 at 08:21:51ID: 25133771

yes, there will be a hardware RAID controller on the system.  Also, I may not place dual quad core processors on it because linux may only utilize 1 of those processors.  What do you think?  railo is leverages the cfm language.

 

by: rindiPosted on 2009-08-19 at 09:02:35ID: 25134213

You don't need the GUI on the server. You can connect to it through SSH from any PC on the LAN, and you can even start apps that run under a GUI from the server, and they will run as a Window there. For that you don't require the GUI directly on it.

Linux has no problems with multiple cores and processors. A lot of the time it will have better built-in hardware support than m$ OS's.

how about RAM?  I was thinking 8GB but I've heard linux debian kernal only uses up to 4GB.  Is that true?

 

by: rindiPosted on 2009-08-19 at 09:54:49ID: 25134805

As long as you use a 64 bit Ubuntu or Debian version you'll see more than 4 GB. It's only the 32 bit versions that have the 4 GB limit.

 

by: COwebmasterPosted on 2009-08-19 at 10:15:31ID: 25135027

ah, ok.  I'm looking at this tutorial to set up ubuntu and LAMP.. http://www.losepoundsdaily.com/lose-20-pounds/index.html

What do you think of it?

 

by: rindiPosted on 2009-08-19 at 10:24:51ID: 25135120

Hm? Can't see anything about how to setup a Server on there... Did you post the wrong Link?

I'd look at the official Ubuntu Server Documentation, I've found it to be pretty complete (you won't have to install/setup everything from there):

That one looks pretty good too.

i just spoke with someone at intel and their motherboards are certified with ubuntu linux but only red hat and suse.  Is that a concern?

 

by: rindiPosted on 2009-08-19 at 11:34:04ID: 25135767

No not really. Those two distro's sell their enterprise versions of the OS and provide support for that price. Also you'll get driver support from intel for those OS's, but it is very unlikely that Ubuntu doesn't include the necessary drivers within it's kernel, Ubuntu is usually more up-to-date than the commercial ones, up-to-date OS's will have more support for drivers, particularly new ones. It's also pretty quick to get the OS installed and to find out if it works with the hardware.

 

by: COwebmasterPosted on 2009-08-19 at 12:17:07ID: 25136219

I'm having the hardware buit custom but I don't want to move forward until I know there is intel driver support for ubuntu.  I'm having an intel motherboard and processors set up on the box.

 

by: rindiPosted on 2009-08-19 at 12:26:19ID: 25136318

The mainboard won't be an issue. The RAID driver may, but shouldn't. If possible get the RAID controller's model number and manufacturer.

Also, there is free clone of Red-Hat available, so if you would need another distro because Ubuntu doesn't work, get CentOS. It is just the same as Red-Hat and is therefore indirectly supported by intel.

 

by: COwebmasterPosted on 2009-08-19 at 12:41:17ID: 25136509

ok, I'm looking into it..

 

by: COwebmasterPosted on 2009-08-21 at 06:22:39ID: 25151490

A buddy of mine installed the latest version of Ubuntu 9.04 on intel 64 bit and it worked just fine.  I have a further question about RAID 10.  Do I need to install Ubuntu with software RAID 10.  I found this link..

http://www.howtoforge.com/install-ubuntu-with-software-raid-10

Again, the system have a hardware RAID controller.

 

by: rindiPosted on 2009-08-21 at 06:38:03ID: 25151652

Not if the raid controller supports raid 10.
