I'm trying to install CentOS5. Although the default partition should work fine for me, but I would like to create my own partition for /var, /usr/, /tmp, /swap, etc. Can you recommend me a good partion including the size. My server has 4GB RAM and 500GB SATA2 HDD. I don't use much space of HDD.
I have a disk in raid, but it seems raid is not working correctly. I took it out, and plug into another server without raid. However, fdisk shows error
#fdisk /dev/sdb device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable.
The number of cylinders for this disk is set to 20023. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help):
Should I correct the partition table now, or should I put it in another raid for checking?
i have installed xen kernel et libraries, i try to install a guest os with virt-install, and when i hit the network installation it doesn't seam to work. The installation doesn't go further.
Anyone has experience with xen ? I'm a good unix admin but i havn't worked alot with xen yet. I can make it work on other hardware but it seams that for some reason it doesn't work on my dedicated server.
I have a VPS with CentOS5 and CPanel...for some reason if I went to that URL it would show the website for the second account created in WHM...so I modified the httpd.conf and added the domain, but for some reason subdirectories won't work on it.
I have been struggling with a couple of new servers that we want to run Centos 5 on. For a second assume that is our desire so going back to 4.x isn't an option yet.
Now while I mention Centos 5, the problem seems to be with PAM and x64.
When trying to login to the server via ssh, the login succeds but then immediately kicks the user out. I have tried this with root and another user created. I have set the UsePam option to no to try to resolve this in sshd_config.
On the H-Sphere forum I found this reference:
" if i try to connect with ssh and i enter the right password i get an error and ssh closes the connection. The answer already was in the ticket you opened:
That is known bug dealt with PAM authentication.
The bug was fixed for i386 systems long time ago. But it was not fixed for x86_64 architecture.
We build FreeVPS kernel new version 1.5-13.1 for x86_64 architecture to fix the problem. We also installed the kernel into the box IP 188.8.131.52.
Please reboot the box with the new FreeVPS kernel version: 2.6.9-freevps-1.5-13.1smp. Let us know the result."
Does anyone know how to resolve this? A reinstall of PAM was attempted by a well known sysadmin here but to no avail.
I tried CentOS5 on my new server. Having CentOS 4 on all other server I never faced this issue. I always get server with vim -minimal installed and I install vim enhanced and common to get text color highlighting.
On a CentOS5 VPS I have access to "yum update" barely working due to the base mirror "styx.biochem.wfubmc.edu" being tremendously slow.
I'm trying to find out how to disable that mirror possibly via a mirror exclude setting in yum.conf or some other way. I've been searching but I've not found any documentation on this so hopefully somebody out there will know how to make this change.
I just colocated a 2U supermicro server for a VPS node and experiencing troubles getting HyperVM (ovz) and centos5 to run on it. First of all, the h/w specs.:
2x dual-core opteron 280 12GB DDR400 ECC Reg. RAM Supermicro H8DA8 mainboard Adaptec 2120S RAID card with BBU, writecache on 6x73GB SCSI as RAID5+hotspare
All firmware updated
I asked DC staff to load centos5 x64. They installed 5.1 and it was running fine.
However, they said centos 5.2 didn't install. So, I ran a yum update and it updated to 5.2 including kernel.
After the update and issuing a reboot, the box did not come back online and on consoling it, they said error messages scroll too fast to be read after the centos splash screen and it loops on like that. Only the 5.1 kernel 2.6.18-53.el5 seem to boot fine though.
I booted with the old kernel and installed hyprvm; set grub to boot using the ovz kernel and rebooted. Sadly, the same errors and server non-responsive.
Does anyone have any clue regarding this issue? Should I try my luck with centos4.7 x64 instead?
I have VPS Windows. I want to resize partition C 50Gb become 20Gb and then create partition D 30Gb for data , I used softwares Partition Manager 8.5 Enterprise Server Edition, Acronis Disk Director Server 10.0.2169 but I can't.
I used command line :
to check HDD on this VPS Server 2003 64b but can't too.
The server I got from LayeredTech has two hard drives, obviously they set up the first hard drive with Linux etc.
The second hard drive is just there, not showing any partitions in 'fdisk' when I checked, so I assume they just leave it blank in every new server for the owner to deal with however they want.
I've been looking up guides to create a new partition for the full size of the hard drive and then mount it. However, it hasn't been very successful. Everytime I created the partition in fdisk, I have to set a size, and then when I mount it, it only says that the drive is ~98MB big.
Is there a way to partition the drive to its full capacity? And then mount it somewhere on the system? Or anywhere I can go to to find out easily?
I recently ordered a new dedicated machine and for some reason the guys set it up so the /home partition is a massive 250GB, and the / partition is a tiny 20GB. Since that's where all the plesk domains will be storing their files, I'd like to resize things a bit. I'm thinking of making the / partition 200GB and the rest for /home
It's a CentOS machine and the filesystems are ext3.
How can I do this resizing, and are there any caveats I should be aware of?
If this is not in the right forum for this... I'm sorry didnt knew where else it may go.
I have to build a new server with RAID 1 and WHM/Cpanel installed (in fact i dont have to, but i need to learn ASAP and my boss gave me an old server for practice).
I've seen the installation guide of cpanel but the sizes of the partitions apply to a disk of 80 GB (i think so) so is there any way to calculate the size of the partitions, regardless of disk size? cuz mine are of 250 gb each.
I'm trying to install it on centos 5 on text mode, so far i have been able to successfully install the system (with partitions of any size... since is a test doesnt matter) with RAID 1.
After that i ran cat /proc/mdstat and in some partitions shows me this
I've read in some places that this is not a big issue... but in other places says it is... maybe i did something wrong
I've got Centos 4 and I'm wondering what's the best way to cleanup my /boot partition?
Tried to do a yum update tonight and it included kernel, amongst other updates that belonged there so it stopped. I've googled around for commands to run and whatnot, but no go... or I just can't find it... if I had to clean it up I have an idea already about what to do, but I want to ask for advice first to see if there's an easier way.
I have two partitions on my hard drive, each have an installation of windows XP, the old partition got corrupt and I can no longer boot windows from it, however I am able to see the files when on the other partition, the problem is I am unable to access the files.
Is there anyway I can get permissions to delete/move those files?
I just received a new server, I have been using always the partition scheme 'x2 ram swap, 1GB /tmp, /boot and /", but im not sure if I should get the new server re-formatted with that scheme (the HD is 250GB, so I will get 2GB /tmp), or stay with the current one:
I just purchased a dell poweredge in order to move my website to its own dedicated server. I have a few questions on the best linux partition setup for a webserver. The system has 8 gigs of ram, raid 10 setup with four 15k rpm drives and two quadcore cpu's.
The os is CentOS 5.1
The server can have up to 30,000 uniques in a single day and can be somewhat database intensive.
Does anyone have a recommend partition setup, besides the default?
With 8 gigs of ram, what is the recommend swap? I've seen rules that say anything over 2 gigs of ram, the rule is S = M+2. So that would put me at 10 gigs swap. Is that overkill?
