CentOS on Compaq Proliant Rackmount Servers
by Robert Hanson 15 Jul '05

15 Jul '05

Greetings, Can anyone relate experience(s) installing CentOS on Compaq rack mount servers units please? Easy no problem, easy some issues, or ghastly do not do it under any circumstances... ;) Basically, I'm looking at some used/refurb dual PIII units and will run RAID on Compaq built in SCSI or is it easy to pop in some 3ware SATA in them? Let me know in terms of CentOS 3 and/or 4 please. Regards and TIA, - rh

Some have i960 microcontroller SCSI RAID, which is rather pathetic these days. You won't break 50MBps sustained writes very easily. > or is it easy to pop in some 3ware SATA in them? They'll take 3Ware cards in the expansion slots, but they typically have SCSI SCA bays, not SATA bays. Check with HP and see if you can get DL3xx series SATA bays (I assume these are DL3xx series)? If you're worried about reliability, buy 10,000rpm SATA drives that typically roll off the same line as their SCSI/FC counterparts. I'm fairly sure the 73/146GB WD Raptors are fabbed by Hatachi and match their specs. > Let me know in terms of CentOS 3 and/or 4 please. Have run RHL9/RHEL3 on the DL1xx and 3xx series, no major issues. It really comes down to the _exact_models_ and _revisions_ (part numbers will do). Do you have those? -- Bryan J.

I've been trying to get the J2SE1.4.2 SDK installed on a Centos 3.5 x86_64 box without success. Does anyone have an rpm for this? TIA Mike

Re: Fix passwd/shadow/group files?

From: Paul Heinlein <heinlein(a)madboa.com> > I think it'll only work for NIS passwd maps, but I think that the > netgroups map can come from NIS *or* live in /etc/netgroup. Right. But in a nutshell, I think we agree that NIS is the way to go. Totally forgot about netgroups and using the +:::::: limitations in /etc/passwd on each NIS client. All excellent suggestions. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Yes, using NIS Netgroups and PAM authentication around them is much, much better on Linux (and even Solaris) than using multiple NIS domains. And even if he still replicates his files manually (he should at least consider automating their distribution via SSH), he can still setup just 1 file and use the same netgroups-PAM solution. Good catch.

Or will it work for local users as well? -- Bryan J. Smith mailto:b.j.smith@ieee.org

Re: How to query the package owning the file? (no packahe manger installed)

From: Prasad Pillarisetti <prasad.pillarisetti(a)gmail.com> > Guys recently I had this question asked in a technical interview. > How do I find out the package owning a particular file, when no > package managers are installed? Impossible. I think he didn't know what he was talking about. He might have mistakenly been looking for... 1. Find the tarball on the system 2. Find the source directory of the system (/usr/local/src)? 3. Use Checkinstall (build package from tarball build) 4. Use rpmbuild -t to look inside of a tarball for SPEC files 5. Others? I guess I just had to be there. > I am assuimg SRPMs are used to install the software? An rpm -i blah.src.rpm merely dumps things into /usr/src/redhat. You go through the SPEC, SOURCE, etc... subdirectories. > Is this actually possible? > Install the Linux OS without a package manager? Of course! There are "packages"** distros like Debian, Fedora, etc... based. And then there are "tarball" distros with some meta-data** in the tarballs, such as Slackware. [ SIDE NOTE: Both DPKG and RPM are System V cpio archives, pretty much the same USTAR format as tar itself, but use 5KiB blocking instead of 10KiB blocking by default. ] Newer to Linux (but no stranger to BSD) are "ports" distros, such as Gentoo. It uses a centralized build system whereby instead of a "package manager" that creates the SPEC (RPM) file, config/Makefile and other commands and bundles it into a single file, the "ports" repository (e.g., Gentoo's portage) just gives you basic Makefiles and other meta-data, and you actually fetch the software. > I know "rpm -qf filename" gives the package owning the file. > But how to get the package name when I don't have any > package manager? Maybe this was a question to rattle me? Of course. People do it all-the-time. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Any reason you haven't considered NIS? If you're worried about passwords, setup Kerberos for authentication. It's easier than you think. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Re: Upgrading from RH AS-3 to ??
by Penelope Fudd 14 Jul '05

Oh, and after it's all done, when rpm looks like it's permanently broken with errors like this: # rpm --rebuilddb rpmdb: Program version 4.2 doesn't match environment version error: db4 error(22) from dbenv->open: Invalid argument error: cannot open Packages index # The solution is: # cd /var/lib/rpm # rm __* # rpm --rebuilddb Thank heavens for Google, and that pasting error messages into it is the fastest way to get help. -- Penelope Fudd <centos(a)ch.pkts.ca>
