Re: Apparently no swap configured

Maybe I am also flirting > with disaster, but haven't been bit yet in years. I believe that the current recommendation is 2 x physical memory up to 2 GB and then 1 x physical memory thereafter. See: http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/html/Deployme… " Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and then an additional 1x physical RAM for any amount above 2 GB, but never less than 32 MB. So, if: M = Amount of RAM in GB, and S = Amount of swap in GB, then If M < 2 S = M *2 Else S = M + 2 Using this formula, a system with 2 GB of physical RAM would have 4 GB of swap, while one with 3 GB of physical RAM would have 5 GB of swap. Creating a large swap space partition can be especially helpful if you plan to upgrade your RAM at a later time. For systems with really large amounts of RAM (more than 32 GB) you can likely get away with a smaller swap partition (around 1x, or less, of physical RAM).

Re: [CentOS] CentOS 4.7 Server CD - update frontpage
by Spiro Harvey 29 Oct '08

29 Oct '08

I know it's going farther off the beaten topic here, but just received this email of warm wishes from our friend Spike Turner that I thought I'd share. It's not even necessary to insult him, he's done it all for himself.

Installer stopped short
by Niki Kovacs 29 Oct '08

29 Oct '08

Hi, I just tried to install a CentOS 5 desktop on very recent hardware, an Acer desktop machine. The installer stopped short very early. I gave Ubuntu 8.04 a shot, and it installed without a problem. Now what can I do about this? Is there a way to use some "enhanced" kernel (like the centos.plus kernel) to perform the install? I guess what's missing there is a specific driver for something (SATA drive? Processor?). Any suggestions? Niki

CentOS 4.7 Server CD - update frontpage
by Spike Turner 29 Oct '08

29 Oct '08

Perhaps with the release of the CentOS 4.7 Server CD the frontpage at www.centos.org could be updated to reflect this new development rather than 4.4? Here is the announcement for those who missed it http://lists.centos.org/pipermail/centos-announce/2008-October/015328.html Spike. __________________________________________________ Do You Yahoo!?

Problem with svn/apache
by Joe Tseng 29 Oct '08

29 Oct '08

I hope someone can help me with this b/c I'm stumped... I had set up an svn repository a while ago with an apache/webdav front end using the default centos packages. For some reason this morning it stopped working for me - it would give me a 403 error. I suppose the problem is with Apache and not svn. So far I've checked the following: I use a couple of files called svn_htpasswd_file (for userids/password hashes) and svn_auth_file (users, groups and permissions) - I verified the files were still apache:apache and were user-readable Just for grins I ran "chown -R apache:apache" on my repository home directory and all repositoriesI made a new user entry in the two files listed above with full admin rightsI restarted httpd and rebooted the serverI made sure the httpd processes were running using apache as userAnd I've run out of ideas. Has anyone else seen this before? - Joe Failure is always an option -- Adam Savage _________________________________________________________________ When your life is on the go—take your life with you. http://clk.atdmt.com/MRT/go/115298558/direct/01/

Can one invoke multiple INSTANCEs of Firefox on CentOS
by James B. Byrne 29 Oct '08

29 Oct '08

I am doing some testing with XForms and I really need a separate instance of Firefox, one that shares nothing with my primary instance that has various reference works and web sites open, to test forms. Is this even possible? I have a sense from the small bit of testing that I have done that even with separate profiles and invoking the firefox process manually from different terminal windows does not provide a completely separate running instance on the desktop. Is there a way to do this? If so then how? Regards, -- *** E-Mail is NOT a SECURE channel *** James B.

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. Thanks, Dave Relevant info: uname -a: Linux internal-name.domainname.com 2.6.18-92.1.13.el5 #1 SMP Wed Sep 24 19:33:52 EDT 2008 i686 i686 i386 GNU/Linux relevant portion of httpd.conf: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /path/to/drupal-current ServerName publicname.domainname.com ErrorLog /path/to/logserror_log CustomLog /path/to/logs/access_log common </VirtualHost> /etc/hosts: 127.0.0.1 localhost.localdomain localhost internal-name 12.34.56.78 publicname.domainname.com 12.34.56.79 db-server.domainname.com db-server

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
