I am planning on moving a few of my machines over to CentOS 5.4, and was wondering what the requirements are for both the 32 and 64 bit versions. So what are the requirements for CentOS 32 bit and 64 bit?

What are the system requirements for the CentOS 5 liveCD?

I am using CentOS 5.6 (64 bit) as a client of Oracle Virtualbox.I do have virtualization enabled in BIOS and VT-x is enabled in VirtualBox.I've checked other sources, and some say that VT-x is enough, but another source says VT-x and VT-d are both required on the cpu.

For some of them I used apt-get ( yes I had to install apt first) and the other, I used yum.
But when I run ./configure in libtorrent-0.12.4 directory, I get this error at the end of it's process:
checking pkg-config is at least version 0.9.0... yes
checking for OPENSSL... configure: error: Package requirements (openssl) were not met:
No package 'openssl' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables OPENSSL_CFLAGS and OPENSSL_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
What should I do to install it?
Problems with xen 3.1.2 creating and installing domU CentOS 5.5 I am trying to do a virt-install --prompt --paravirt, and the install error out while trying to download install RPMs. I have googled for xen centos virt-install and various permutations. I have found similar howtos for 5.4 and 5.3, but they resulted in the same outcome. I did find several posts with similar issues, but no solution was posted.[URL]..

View 1 Replies View RelatedI have two servers, both running CentOS, but one running Cpanel as the control panel and the other running Webmin.
I would like to sync the web folders using rsync. However, when I sync the files from the Cpanel host the permissions look as follows:
Code:
But that doesn't work on the Webmin server which needs the following:
Code:
It seems the Cpanel install has the group as 'nobody' whilst webmin has it the same as the file owner. I can fix this by running:
Code:
But as the file transfers will be frequent, I don't want the files to be inaccessible until chown is run.
So, what I really want to know is - how can I change things on the 'webmin' server so that files with ownership owner:nobody will run?
The installer can't see my raid controller (I assume) as I'm getting the following error:"Error opening /dev/mapper/isw_jbhgjgjj_Vol0: No such device or address"It just sees them as 4 individual drives: sda, sdb, sdc and sdd.Please note that I have set up the RAID 5 in the controller bios interface and the image name is Vol0, which it seems that it tries to load but for some particular reason it can't.I have also tried different bios settings and nothing worked.

I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :
marte:~ # file /mnt/vmlinuz-2.6.18-92.el5xen

The first server I installed installed fine. The second server, installed with the same config, went to "kernel panic not syncing no init found try passing init= option in kernel" error. I tried reinstalling but it keeps going to that error after install reboot. The storage is ISCSI connected via Intel Server Adapter, which allows it to boot from ISCSI. Not sure if that's the cause for the problem, but the first server is connected to the same ISCSI and installed just fine.
Is there a way that I can make sure ISCSI module installs during installation? Although I think it is installed since it's able to copy the files and setup /dev/sda. I just wana make sure that it installs during setup.
I'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail
mkdir /mnt/nfs
mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).
Here is the remainder of the KS :

I have installed CentOS 5.3 on my PC which has an Atheros AR8121/8113/8114 Gigabit Ethernet. Unfortunately 5.3 has no drivers for this LAN Card. I searched the Google for drivers but was unable to find any. Does the 5.4 has them? If yes then how can i upgrade it to 5.4 without Network connectivity?
View 11 Replies View RelatedI built a home server (NAS/WWW/SSH/media server etc) and chose CentOS 5 as the OS (stability, easy of configuration).I was just about to start tuning the power consumption when I realised that the kernel CentOS uses is so "old" that it does not support the latest reduced power consumption enhancements that Linux has achieved in big strides in the recent past (we are probably still talking 6-12+ months ago e.g. tickless kernel)..
So my questions; 1) I know CentOS was maybe not meant for home servers (certainly its not its primary purpose), but if it is, any ideas of what kind of power consumption it takes (I know its relative) and if there are particular power consumptions that are worthwhile?
2) Do you recommend me compiling my own 2.6.21+ kernel from kernel.org or am I just likely to have compatibility issues (I really did not want to do that) or when is CentOS 5.4 supposed to have a newer 2.6.21+ version kernel?
Was it wrong of me in principle to choose CentOS for a home server when I am power conscious? (I don't have a low-power VIA processor either but a P4 so I am really just hoping to make do with software changes).
I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?
I have a Centos 5.2 VM running under Windows 2008 Hyper-V. If I add two "legacy Nic's" and bridge them, everything appears to work fine. However, if I remove the legacy nics and replace them with two synthetic nics (linux integration components), the nics seems to function fine UNTIL I add them to a bridge.This VM will eventually be used as a DansGuardian/Squid transparent proxy for a local library. The logical layout is represented by the attached jpg image. I have also included the ifcfg- scripts for the adapters and bridge for both scenarios.It would also be useful if someone else has Hyper-V with the integration components and dual physical nics to see if they can reproduce my symptoms on their box.Legacy Adapters:

If I ssh from my laptop (running F10) to the server (centos 5.2) it asks for the password, but everytime I enter the correct password it says incorrect password. when I do the same from the server to my laptop I can get in just fine. I think my passwords are stored as ssha in the LDAP (I tried clear passwords and that dosen't work either).

View 10 Replies View Relatedi didnt find a solution to a display problem im having. my server mobo is an asus k8n-dre with built in video. after the install(using built in video) the screen dosnt display fully as in black sections on the left and top of the screen. from the searching i did i found something about an "xrandr" command that would let me change the video settings but it didnt do anything with the black areas when i tried it. i also have a nvidia geforce 9500gt video card so i changed the jumper to boot from it and tried again. the black sections are still there but the centos display covers much more of the screen now. theres still about a third of an inch gap on the left hand side and about 1/4 of an inch on the top. ive also tried updating the software to see if it may be a driver issue but no luck. anyone know how or if it can fit to full sceen? the screen displays up to 1440x900 if im not mistaken but with the built in video it gave me lots of display options including the 1440x900. after changing to the nvidia card it only shows 800x600 and 640x480.

I've installed CentOS 5.3 on a machine, and I need a Samba version 3.2 or higher. Since 3.4 is out, I thought I'd grab that. But, "yum list|grep samba" gives me only version 3.0.33. Is there a package of Samba I can grab that will upgrade the 3.0 installation so that I don't have two laying around? If not and I need to compile from source, do you have any suggestions for what arguments I should give configure? I'm not used to Linux coming from the BSD world
View 1 Replies View Relatedi find this is an issue which might be tiresome for everyone except for those experts. Esp. for the computers which are dual booting(both windows xp and centos installed in the same computer), that when we are in CentOS we need to switch onto windows immediately. and vice versa. i see this is possible only by shutting down the centos/windows and then restarting onto the other OS.
Can anyone tell me the the solution to work simultaneously both xp and centos without the need of shutting down and restarting There maybe or may not be the solution...but i find the pleasure to know if there is for example, remote desktop connection in windows xp, is there any solution, we can work on windows via centos or vice versa ( in the same machine),
I just upgraded by box from Fedora Core 9 to Centos 5.2. Finally!I have a 500GB SATA drive, it's partitioned into three equal size slices, hda1 through 3. The old Fedora was on hda1, I installed the new Centos on hda3. I instructed the installer to write the MBR to /dev/hda, not /dev/hda3. Fdisk says I have sector 0 unused.First, the system wouldn't boot - it just looped through the BIOS, rebooting over and over again. The BIOS sees the disk, but it never loaded Grub. I tried re-running grub-install /dev/hda, and not I get a Grub Error 17 after stage 1.5 loads.
I can boot from rescue OK, the grub.conf man menu.lst look fine, it's pointing to "root (hd0,2)". It's either the BIOS that can't find the MBR, or the MBR can't find Grub.When I looked at the disk with fdisk after the install, hda1 was still marked bootable, hda3 was not, so I swapped bootable flags but that has not made a difference. I also appended the new grub to the old grub thinking I could get the MBR (if it is there) to load the old grub and thence find the new Centos, but that didn't work either.Mobo is an old Shuttle AK35.Any ideas? Did I mess up by not telling the system to put the MBR on /dev/hda3? Is there a way to fix this without reinstalling?
we are using firefox-3.0.15 from the CentOS-Repository and the adobereader plugin from the adobe-repository. We have a curious problem with adobereader-plugin in firefox.When a pdf document is displayed via the plugin, i.e. within a tab in firefox, all input fields are disabled. I cannot enter a search string or fill in fields. The cursor and page up/down keys are also disabled. But when I configure firefox to open pdf documents with the external acroreader, everything works fine.
Additional notes:* We are just migrating from SuSE. Some user profiles are working as expected without problems. Unfortunately, I was not able to figure out the important files: I traced all of firefox' file operations on the user profiles, but there are no significant differences between working and non-working profiles (I just compared filenames, not content).* the same adobe-plugin works with firefox 3.0.15 from mozilla.org* I also set up a clean i386-Centos 5.4 from original CD, SELinux disabled, updated and created standard user. I only added the adobe-repository. The same effect, no search avaible.
I've just installed CentOS 5.4 on my Thinkpad T43. Everything works fine except one thing that, when I suspend the machine, the hard disk is always shut off in a "hard way". The sound is similar to the one you would hear when shutting down the machine by keeping pressing on the power button.. this is no good.
