I'm not a Debian user, so I want some advice how to install Debian 4 as guest OS on top of Centos 5.2 dom0.
Mostly on Google, there's a manual on Centos on top of Debian. I've tried to use the netinstall iso for debian and mount it on /var/www/html/debian and use it for remote install source. So far don't have any success on that.
I'm leaning towards centos but am concerned that development priority in that distro will switch over from Xen to KVM as RHEL does. Which distro would you choose for dom0 and why?

I have tried installing Ubuntu as a fully virtualized guest, but the Ubuntu CD doesn't even bootup. I get the Linux bootloader, and that's it,it doesn't continue to boot. Odd.
When trying to install a Paravirtualized guest, I had to use the debootstrap method, but can't get it to boot up.

how to get Ubuntu working on a CentOS / Fedora Core XEN server?
Which OS is better in security and easy to use for vps beginner:
CentOS™, Debian™, Ubuntu™, Fedora™, or Gentoo™.?
which is best for running a server? debian or centos?
i have seen many companies prefer using centos for running servers quite often. Any specific reason for that or am i missing something here.
I am currently using Ubuntu (debian) server 7.10 for web hosting but see a lot of discussions about Linux centos.
Which linux OS do you prefer for hosting and why....
Just figured I would throw that out there.
I will be dropping my shared-hosting plan and ordering a small VPS as soon as I can decide on which operating sytem to use. It seems that most companies offer the following choices: Suse, Debian, Fedora and CentOS.
I freely admit that I am a full-fledged n00b when it comes to linux and will be learning as I go, the problem is I just don't know where to start because I'm not familiar with any of them. I have at least heard of Suse, Debian and Fedora before, but didn't even know this CentOS existed until yesterday... and yet, it seems to be one of the more popular choices.
So I was wondering if some of you seasoned VPS veterans here could recommend an OS, tell me what the differences are, or otherwise share any experience you might have with any of them.
I am attempting to migrate from a debian os server with the latest plesk 12 to Centos (rather cloudlinux) and would like to know if there are any options that should not be checked during the process?
I recently tried to do the normal procedure, which is to transfer all objects, etc. And for some reason the percentage went from 1-50% to then back to zero.. but when clicking to check the current status, its still working
Status: in progress
Current operation deploying domain.com
current operation progress: empty bar
Different sites are transferring, but I am not sure if the migration will effect the system because the difference in OS folder structure and file location.
Gazzin.com offers so many OSs on their VPS deals - CentOS, Debian, Fedora Core 3, Fedora Core 4, Gentoo, Opensuse, Suse, Unbuntu. Which one would you advise me to start from?

HTML sites are fine, but all php and wordpress sites are giving a 502 error after fully migrating. I repaired with Webserver Configurations Troubleshooter and rebooted and its still giving me the same issue.Also, noticed my previous server had php 5.4.36, the new CentOS server has 5.4.37.
View 5 Replies View RelatedI've been running 3 Xen servers for the last few months in a production environment, and facing a strange problem with one of them.
Server 1 and 2 run a couple of DomU's and are running just fine.
Server 3 runs one DomU and takes care of all the backups for the DomU's of Server 1 and 2
The DomU on Server 3 is crashing every night, right when the backups are being made.
DomU becomes inaccessible, but keeps appearing at xm list with state ------
When I try to connect to the console it wont let me connect. The only way to get the DomU back up is by using xm destroy and xm create again.
For the back-up I use NFS where the DomU on Server 3 is the host, and the other DomU's of Server 1 and 2 connect to it through an internal bridge.
Below you'll find some information about Server 3:

I just ordered a server which has that setup:
AMD Athlon 64 X2 6000+ Dual Core
8MB RAM
2x750GB RAID 1 HD
Now I wanna run it with DirectAdmin, but obviously DirectAdmin doesn´t support the Debian 64 which is installed but only 32 bit Debian.
Now I wonder wether I could setup a Debian 32 as well on that system and if yes, wether it would give me a deficit in Performance?
Or would you rather go with CentOS 64 which Directadmin supports?

First you need to download the .deb packages using the follwoing commands
i did the three steps..
Now you need to install .deb packages in the following order this is very important
#dpkg -i nxclient_2.1.0-17_i386.deb
#dpkg -i nxnode_2.1.0-22_i386.deb
#dpkg -i nxserver_2.1.0-22_i386.deb
If you get any errors use the following comamnd to fix
#apt-get -f install
Now you need to make sure ssh and nx servers are running if not start with the following commands
#/etc/init.d/ssh start
#/etc/init.d/nxserver start

And what about php using cron so execute with php-cli how to secure it?

I've just ordered a dedicated server with Ubuntu server, but they've come back to me to say that they've had trouble installing Ubuntu server on these particular servers.
As an alternative, they're offering to install Debian. My concern is that I come from a windows background and have spent the last month reading and playing with Ubuntu Server in vmware. I'll be running a small handful of sites on the server and will rely on the apt-get and package installer in webmin to get things set up and for administration. I'll dabble in the shell a little, but only when needed.
Should I go with a different host that can offer Ubuntu, or will I be okay with Debian?

Linux user trying to install a few packages on a new dedicated Debian server.
Following some tutorials, I installed Apache1.3 & PHP4 using apt-get install and had them up and running no problem.
I then decided to change the versions, so removed them using apt-get remove and deleted the relevant folders from /etc (this was before I knew of the apt-get --purge option).
I then tried to install Apache2 and PHP5, and although it appears to have worked, folders are not created for them in /etc so it doesn't work.
Is there a way of doing a fresh clean install so that the folders are created? I've tried apt-get clean without success.
