Possibly OT: intermittently long response times when connecting to host
by David Miller 29 Oct '08

29 Oct '08

I have a CentOS 5.2 server running Apache 2.2.3 (yum installed) and drupal 6.5 on ESX 3.5. We're using Name Based Virtual Hosting on it - 2 hosts. The problem is that when I pull up a web page after not having accessed it for ~15+ minutes it takes between 10-12s to load fully. The 2nd page, 3rd page - and sometimes more than that - take between 8-12 second. After that - decent performance, though not great (0.3s to 2s). Wait ~15 minutes, maybe more, maybe less, and it goes back to slow. While it's been most apparent with httpd, I've noticed similar slowness with the initial ssh session, etc. I know what you're thinking. DNS problem, right? Yeah, me too. But for the life of me I can't find a problem. This is at a colocation site where we have other servers - all of those are just fine. We've got an almost identical box internally - working just fine. I can do an nslookup off of each of our different internal name servers and get identical and immediate responses. I've done tcpdumps (both on the client and the server). It shows the request gets to the server immediately. I've started httpd using strace and not seen anything glaringly wrong (though I'm not well versed in the output I have enough C under my belt to have an idea what's going on). Thinking it was code that the developer working on the project I pulled all the custom drupal modules out and it's still slow. Even created another virtual host with a stock drupal install and it's slow (identical results). I moved the mysql server from local to our central DB server. Load avg never gets above ~0.10 so I don't think the box is stressed. Watching the ESX load average it looks good too. I've tried a hell of a lot of other things and tried to include all the relevant information so apologies in advance for anything I might have left out.

cmirror - CentOS
by Rajagopal Swaminathan 29 Oct '08

29 Oct '08

Greetings, I might have missed something in the list here.. But could someone point out some introductory material / docs regarding cmirror? Is there something (even beta would do) in CentOS to read and understand about this? OT- On Fossils: While I cannot claim "Fossil state" anywhere near some of the people who were doing cards -- I knew about them though -- when I was born, I have had my spell flicking switches to select boot device on a Texas Instrument DS 990 switching between the "Washing machine" disk and the 9" tape drive. (Now this is in India when a lot of restrictions -- both by Indian and other governments -- were there in Technology imports) The interesting part of it was the entirely memory mapped design and barely a few registers... and then in Prime 750 which had 5 huge boards which constituted a CPU. and a "hefty" amount of RAM -- 8MB. The thigs is they worked 24x7 and we were required to give a month's notice before shutting them down / rebooting unless there was a breakdown which was very rare. Just like Linux ^H^H^H^H^H^H Centos Servers Regards Rajagopal

"core" installs of 5.2 missing crucial packages like yum, selinux-policy-targeted, vim-minimal, etc.
by Johnny Tan 29 Oct '08

29 Oct '08

I had a 5.0 kickstart server which did "core" installs of CentOS (i.e.: "%packages --nobase"). I recently setup a 5.2 kickstart server. Using the same kickstart configs, I notice a few packages are always missing, notably: yum (!!), selinux-policy-targeted (even though I have "selinux --enforcing" in the kickstart, it always ends up with that package missing and selinux disabled), vim-minimal, etc. Looking at comps.xml for 5.2 os tree, it shows all of these packages in the "core" group, just like 5.0 does. So it's not that the "core" group has changed. Looking at the Release Notes for 5.2, I see this entry: "Kickstart scripts that worked for 5.0 and/or 5.1 may have issues on CentOS 5.2 installation trees. So first test your kickstart scripts with CentOS 5.2 before using them in production." I'm guessing this has something to do with my problem, but there's no further details. Does anyone have any insight into the above Release Notes entry, and/or my problem in general? p.s. I setup a 2nd kickstart server in a completely different environment, and am still seeing the same issue. I'm about to try a CD-based install of 5.2 and see if that also has the issue. johnn

how to get rid of "kerberos"
by Marcelo M. Garcia 29 Oct '08

29 Oct '08

Hi How to get rid of kerberos, or at least to prevent to go into path? Where is defined the path for users? I need to configure and use rtools (I know that I should use ssh, but I need rtools) and I think very annoying the messages from Kerberized rsh or rlogin, like this: -sh-3.2$ rsh kitten02 connect to address 192.168.89.2 port 543: Connection refused Trying krb4 rlogin... connect to address 192.168.89.2 port 543: Connection refused trying normal rlogin (/usr/bin/rlogin) Last login: Tue Jun 3 20:17:32 from kitten01 -sh-3.2$ But if kerberos is not in path, everything works fine: -sh-3.2$ rsh kitten02 Last login: Tue Jun 3 20:13:13 from kitten01 -sh-3.2$ Thanks Marcelo

Minimal CentOS
by Puneet Goel 29 Oct '08

29 Oct '08

Hi! and a warm hello to the CentOS team. I have a work for which I need some solution from you. Actually we have some thin clients where we want to put a light weight Linux distro for users. As of now I have tested with Fedora and Ubuntu distros but the issue I am finding is they are not able to fit in my requirement of flash based hard disk consumption (~500 MB). although a distro named TinyME which is a custom version of PCLinuxOS seems to be very near and with a little customization by putting XFCE it was around 600MB. but it is not well known and supported. I have also tried CentOS 5 and 4 (with bare minimum installation) but it is coming little heavy, however later on I came across a link (http://www.owlriver.com/tips/tiny-centos/) providing a kickstart file for a bare minimum CentOS 4. It gave me CentOS 4 which ate around 400 MB. However it was little near to my specs but without a usable Desktop (KDE and Gnome seems to be out of question because of heavy size). Now I need some suggestions from you to make it work on my system. I need a light version of CentOS (I am very much particular about OS identity and the final product will retain the parent OS identity and quality). Can you provide me some kickstart file or something else which can help me in making a final thing. I do not need eye candies/OpenOffice/Adobe flash/Games/Media Player etc. Just a usable desktop, a lightweight file browser and desktop with icons (may be XFE). Redundant locale, man, doc, /lib/modules etc. will be removed as well. Karan told me that he heard someone installing CentOS 5 in 500MB. Can anyone point me in right direction. any kickstart file or iso will be of great help. At my personal end I would prefer to put CentOS (As it is based on RHEL and has an excellent community around). Looking forward to hear from you. Thanks and Regards, Puneet
