CentOS5 - HDD Partition
May 14, 2008I'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.

Jan 26, 2008Trying to get something sorted on a VPS that I want, but when I try to run a script I get the following error:
cp: cannot stat `/lib/libxcrypt.so.1': No such file or directory
which is easy enough for me to understand however, I cannot find what package I need to install to provide the file.
I have searched for libxcrypt* on the box to see if its hidden elsewhere but to no avail.

May 27, 2007I 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:
[url]
" 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:
Quote:
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 64.71.227.16.
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.

CentOS5 VPS - Yum Barely Working. How To Exclude A Mirror/Mirroring For YUM?
Apr 2, 2009On 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.

Supermicro H8DA8 Kernel Issues On CentOS5 | HyperVM
Oct 24, 2008I 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?
How Do I Configure Dedicated IP's On Virtual Machines Running On A CentOS5 Host
May 24, 2009How do I configure dedicated IP's on Virtual Machines running on a CentOS5 Host?
I installed VMWare Server 2 almost without a problem using no GUI, I now have the web interface for the VMWS2 and any machine I create and run on it seems to do so without a problem.
The thing is, I can't connect or know how to configure this virtual network so I end up using 2 dedicated IPs on the Virtual Machine.
Cpanel VPS - Plenty Of Free Memory, But 'committed' Memory Exceeds VPS RAM
Jun 12, 2009I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.
However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.
So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?
Code:
root@server [~]# free -m
total used free shared buffers cached
Mem: 768 449 318 0 0 0
-/+ buffers/cache: 449 318
Swap: 0 0 0
Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory.

Memory Usage :: Put More Content Into Memory?
Jul 16, 2009I just got a new server Dual E5520 with 6GB RAM, SAS 15k rpm raid10. It's running well. However, the memory usage is just around 2.5GB, even when I have more traffic. Here is the kernel info

I'm Missing 7 GB Of Ram: Installed Physical Memory 8 GB / Total Physical Memory 1 GB
Apr 4, 2009I just ordered a server from serverbeach that should have come with 2 GB but I see that this one comes with 8 GB
Unfortunately, I seem to be missing 7 GB of ram.
Installed Physical Memory: 8 GB
Total Physical Memory: 1 GB
Windows 2008 Server Web 32-bit
Now, being a 32-bit system, I should see 3-4 GB of ram right?
Any idea why only 1 GB is available for the OS?

512MB Memory VPS... Out Of Memory Already
Oct 1, 2009I have a 512mb DV server with Mediatemple, which I am running 24 (ish) domains off (most of them static websites) and a teamspeak server. I would say MAX theres 10 users online at a time)
Now, I know its running out of memory because i get frequent QoS Alerts in plesk (kmemsize is apparently the memory size):
Oct 01, 2009 11:52:57 AMBlack zonekmemsize
I have attached my results (when I did top).
My questions are:
1. Should I be expecting to be out of memory running what I am?
2. Is there a way to see the problem domains (memory wise)?
3. Are there any ways I can reduce the memory? (I have followed this already:

4. Where is the memory usage coming from (I am finding it very hard to understand TOP)
VPS Memory
Jun 19, 2007I am hoping someone with experience of these things can comment on memory usage on my VPS partition. The master server on which my partition sits seems to be running at full memory usage and I'm getting lots of fork and mutex errors in apache causing apache to crash several times a day.
I'm running Invision Power Board on there with an average of 100 users in the last 15 mins during most of the day.

Xen Using More Memory
Jun 25, 2009I previuosly have a forum hosted on a VPS with a 512 MB RAM (OpenVZ) and at that time it was only using 300MB of ram during peak time but the server was always down due to harware failures so I move to a new host this time Using Xen with a 768 RAM now it is using all the RAM available which is double the ram that it uses before. Is it really normal for a XEN vps to consume more memory than on a VPS using OpenVZ?

Mar 12, 2008I am trying to optimize my VPS setup and can't seem to get it to use all of the memory that I have. I have problems even getting it to use half of it. What kind of changes can I make so that it uses more memory while reducing load? My recent MySQL and Apache conf optimizations I have read about here and other sites have sent my loads above 1, but the memory usage is staying the same.

Xen Using Too Much Memory
Jun 4, 2008I noticed that, VPS with Xen technology, are using up far more memory than others?
Lets say, I usually use about 300mb of ram in a VPS with openvz, but VPS with xen, with the same usage, is using about 820mb of ram.
Even without running anything...after a fresh install of centos 5, with only few OS processes, its using around 170mb of ram already.
Is this so with Xen? The expected ram usage with Xen? Or am I missing something?

Memory Used On VPS
Apr 20, 2007We are running into yellow status often at our new VPS. We have been with the web host for almost 1 year and recently got moved to a new VPS. WHM often show a yellow status for Memory Used (80% or so). As per the web host, WHM shows RAM for the entire server and not just our VPS. So how can we determine how much RAM we are using so? And to determine if we are using more RAM than we should or if others on the server are the culprit?
never got this yellow status on the old VPS.

Oct 5, 2007if someone here could offer their advice/expertise in this problem. I have a 256MB CPanel VPS. When Apache is restarted, memory is around 180MB which is perfect
However, before long, memory usage is at 240MB. Looking at top processes, this is the top 5 i get...

Anybody able to offer any advice? I see that all processes are httpd, is lighthttpd or lightspeed a solution?
The main site serves up php content (No mySQL) and a few images. It also has a LOT of image requests which are redirected by photobucket via .htaccess.
The secondary site on the server (not yet launched) is going to be an arcade site running gamescript. I have been hesitant to release this site untill these memory issues are sorted.
