Which Operating System
Feb 18, 2007There's bloody heaps of them. Which one do I go for on my two new file servers? Which operating system out of these is the most common, has the most support, is most compatible? The server will be used to host videos and will run c-panel. A light weight OS is probably preferred but I really have no idea. And incase it helps, the servers have 512mb of ram, about 30 - 40GB of hDD (not actually sure) and an old AMD Duron.
CentOS
Debian
Direct Admin
Fedora
FreeBSD

Nov 15, 2007Without having all of the operating systems at my disposal for testing, I would like to figure out a way to determine the operating system of a remotely accessed Linux machine.
It seems pretty strange though, since cPanel reports both machines I am using as being
CENTOS Enterprise 4.5 i686, yet one's uname -a reports:
Code:
Linux hostsentry.crucialwebhost.com 2.6.9-023stab044.4-enterprise #1 SMP Thu May 24 17:41:23 MSD 2007 i686 i686 i386 GNU/Linux

Linux main.7kb.org 2.6.9-55.0.6.ELsmp #1 SMP Tue Sep 4 21:36:00 EDT 2007 i686 i686 i386 GNU/Linux
I'm assuming there is a way to determine the OS from this information. Anyone know how?
Preferred Operating System For Web Serving
May 13, 2007I have been online since 95 and I've got a lot of information I could help others with regarding web development and interface design.
One thing I'm terrible at is System Administration, but I'm getting better and my first step is to pick a reliable operating system for both the webservers and the database servers. Would anyone be willing to answer the following questions or point me to a thread that already discusses these?
A little background, our site has 200k members, 30k active and is growing by about 5k a week. We still run MySQL 4.0.27 on the DB servers and they are running FC2. The webservers are Apache 1.3.37 and PHP 4.4.2 running FC2 and FC4 as well.
My questions
1. What OS would you prefer to upgrade to for the web servers? and a
"few" reasons why?
2. What OS would you prefer to upgrade to for the database servers?
and a "few" reasons why?

Hardware Level Virtualization Or Software Level Virtualization

KVM Hypervisor And Guest OS Setup
Mar 15, 2009I have been using Linux for the past 3 or so years, either running it for workstations or servers, and now I want to set up a server for Virtualization. I have been doing a fair bit of research about the different ways of doing this, and I have decided to go with KVM. I usually use CentOS, but will have to use Debian to use KVM. I just have a few questions about the best way of setting it up.
We have a pretty powerful server* which we are planning on collocating to a data centre and running web servers from the VMs. Virtualization seems like the best way to allow for simpler administration, and also allow us get the most out of our server's resources.
*Intel Xeon X3230 Quad Core, 8GB Ram, 4x 15k 147gb SAS (RAID 6)
What is the best way to set this up then? I was thinking we could install Debian as the Host/Hypervisor over the whole drive, and give it a 16GB swap partition. Then I guess when the VMs are installed they live on the Debian drive as a file, or do they need their own partitions?
Are the guest OS's capable of using the Host's swap space? Its bad enough losing 16GB as a swap partition to the host OS, but please don't tell me I need to supply the VMs with their own swap partition aswell - im curious as to if the server will ever need to use swap space as it has alot of ram, let alone require extra swap for each VM too?
KVM is still very new, but does anyone know any good books/resources out there? The virtualization books I have seen don't seem to cover KVM, just Xen and others.
32 Bit Xen Guest On X86_64 EL5 Node
Oct 18, 2009Let's make this straight,
I have this vps,which is pending cancellation in a few days.
Hardware Node = EL 5 x86_64,
Vz = Xen
I asked my provider for 32 bit centos, I even rebuilt it, but my "uname --all" still
Quote:
Linux xxx.xxx.com 2.6.18-128.1.10.el5xen #1 SMP Thu May 7 11:07:18 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
so I opened a ticket asking about the vps arch.
The provider have told me that to run a vps 32 bit guest, what you have to do is (?)
+++++++++++++++++++++++++
yum clean all
echo i686-redhat-linux > /etc/rpm/platform
+++++++++++++++++++++++++
so yum will exclude any x86_64 packages.
The provider has told me also that my "uname" display x86_64 because the hardware node is 64 bit. Is this true ?
I'm no linux or vps guru, but that's doesnt feel right at all.
This has cause me some issues especially with kernel-headers and some program failed to compile.
So, is it possible to run a 32 bit OS as xen guest inside 64 bit node?

View 9 Replies View RelatedVMWare - WinXP As Guest On CENTOS - Networking
Sep 8, 2007OKay here is the set up:
I have a CENTOS 64bit running, with 1 guest OS (WinXP) in a VMWare Server. I have tried the following: I have 6 public IP's attached to my 1 Ethernet card in the CENTOS host.
Try 1:
The Guest OS is set to use "Bridged" Networking. This allows full use of the internet, in both directions. Not exactly optimal, but it does work. I can reach the Guest via RD, which is a requirement for this client. The guest OS is mainly assigned one of the 6 public IP's (x.x.x.118). The problem with this setup is the Guest OS can not reach the host. For example the host has a mail server on it, and when the Guest tries to reach the host, it times out.
Try 2:
The Guest OS is set up to use "NAT" and gets 192.168.100.128 as its IP via DHCP inside of VMWare. The nat config file for VMWare is set to open port 3389 (RD port). Guest OS can reach the host with out any problem, and can reach the internet with out any problem, however I can not RD in to the Guest OS.
I prefer setup number 2 for all the obvious reasons, but I just can not get my IPTables rules to work. This is what I thought should work, but does not:
iptables -t nat -I PREROUTING -d x.x.x.118 -j DNAT --to-destination=192.168.100.128
iptables -t nat -I POSTROUTING -s 192.168.100.128 -j SNAT --to-source=x.x.x.118
I realize that would have done all traffic, and defeated the benefits of NAT,but since forwarding only 3389 was not working I tried forwarding everything.
Any suggestions?
Xen Update, On Bringing Guest Networks Back Up
Jul 16, 2008After a yum update on a centos 5.2 box (including an update to the latest version of xen) my guests don't have a network connection anymore (nor windows, nor linux VMs).
The windows VM does see an unknown PCI device (great, no drivers and no internet), of which I guess is the network card seeing there are no other network cards listed in the VM.
MS Virtual PC - How To Access My Localhost (Apache) Subdomains On Guest OS?
Mar 23, 2007I've just downloaded Microsoft Virtual PC and the Internet Explorer 6 Application Compatibility VPC Image containing an XP installation for testing sites with IE6 [url].
Everything works fine, I chose VPC Shared Networking (NAT) and I can access the internet from the VPC as well as my Apache development server which runs on the host OS (Win XP) by going to the host's IP address which is [url] in my case. And here I have 2 problems:
1. I want to access [url]on VPC just by typing [url]. I added the following line to the hosts file:
192.168.52.141 localhost
But this doesn't work. Interestingly, any name other than localhost works fine, for example:
192.168.52.141 localhost.localhost
or
192.168.52.141 local
This is not a major problem but I'd prefer localhost. Any ideas how to do that?
2. And the more important issue: on my host OS I have some development sites which I have set up to be accessed by subdomains, for example [url], in httpd.conf:
Code:
<VirtualHost 127.0.0.3>
ServerName perfekt.localhost
DocumentRoot C:wwwperfekt
DirectoryIndex index.php index.html
</VirtualHost>
and in hosts file:
Code:
127.0.0.3 perfekt perfekt.localhost
And now I want to access this site from my VPC too by using subdomains like this! How can I do that? The address 127.0.0.3 seems to be local to the OS and VPC can't see it. I have tried setting other IP addesses in httpd.conf but nothing outside the 127.x.x.x range works on either OS. I suppose I need to make each of my sites to be seen under a different IP from the outside network so that VPC (which is "outside" the host OS) can access them - then I just set up the appropriate subdomain names in VPC hosts file -
How Do I Host Windows 2008 Server As A Guest OS On My Linux Dedi
Apr 26, 2009How do I run a virtual instance of Windows server 2008 on my Linux dedi? Do I need to partition the server and create a VPS for this or can I run it on something like VMware? (Please look at my other thread here [url]t=857377 to learn more about my server, its resources and current config.)
Why would I want to do this? Because my primary desktop OS is still Vista Ultimate 64 and I've invested a lot in Windows-based software and hardware--too much to make a total switch to Linux. But, I don't want to invest more than I have to in order to run a Windows server that allows my business partner to access documents remotely or for us to share various files securely and privately and still serve my mostly Windows-based clients and colleagues. I'm one of, well, two people I know who even use Linux (at least at the OS level and know it).
Since my research shows I **can** do this on Centos 5, the responses that would be most useful to me would be those that focus on how I can do this successfully (even if it seems complicate; I can figure it out with help and/or direction) and what to consider or avoid when creating this virtual guest OS on my Linux dedi.

COMPANY X has colo racks in DATACENTER and hosts a client named COMPANY Y. COMPANY Y also hosts 50 small web sites on cpanel and 40 VPS servers on their linux VPS node in exchange for a discount or other compensation. During the month of may and COMPANY Y's bill raises from being 3000 past due to over 12000 past due to various reasons including purchasing of hds from the DATACENTER using COMPANY X's account, tech work dont by DATACENTER for COMPANY Y needed also billed to COMPANY X's account, as well as BW and rack costs. Seeing this alrming bill by the end of May COMPANY X begins putting pressure on COMPANY Y to pay some invoices as no payments were received during the entire month of may and COMPANY X is also having a hard time paying DATACENTER due to not being paid by COMPANY Y but makes efforts to pay 25% of the outstanding bill in June.
Near the end of june COMPANY X has had enough and arrives at the datacetner to attempt to move theritr clients off COMPANY Ys hardware so they can suspend service of COMPANY Y completely. On the visit COMPANY X brings 2 new servers in and begins moving clients of their over and COMPANY X notices this action and begins to suspend and remove access to all of COMPANY X's clients. COMPANY X then decided to power off the boxes of COMPANY Y and removes drives containing COMPANY X customer data for offline recovery. and because they beleived the DATACENTER might be untrustworthy enough to release hardware fromt heir rakcs without their permission. The drives were for as much colatteral purposes as for recoverying customer data. They then pack the drives in boxes and a bag and leave the datacenter having spent nearly 20 hours working and head on a long trip home and signs out of the data center in front of various techs holding the server parts and tools.
Upon arriving back to their office/home
They were informed that the removal of the HDs was not allowed byt he datacenter because the account was past due and it was discovered that several drives with cOMPANY X's clients were left in the datacenter which COMPANY X now wishes they had remembered to get.
