You'll need some packages in Compatibility Arch Development Support to build My friend Vic says:Ĭrapload of i386 binaries and libraries that run on x86_64 RedHat systems Some apps don't understand 64bit libs, so these older But quite often you will have a matching package of the same In 64-bit machines, most of the packagesĪre x86_64.

#CMAKE LINUX FERMILAB INSTALL#
Just need to get the "special" distro ISO to install on the 64-bit hardware and it will be good to go. RHEL 3.0 and 4.0 maintains simultaneous relese/update levels for 64-bit platforms as their popular 32-bit x86 OS. Some of the more often run-into diff for sys admin: Gnome/KDE for Display Manager (see XDMCP).Some of the most notable things that Linux does rather differently than kargs="nopti console=tty0 console=ttyS1,115200n8" Somewhat helpful shell function to see if there are recent core dumpsįor entry in $(ls /kdump|grep ^) do Kernel /boot/vmlinuz-2.6.18-371.11.1.el5 ro root=LABEL=/ this WILL CRASH the machine:ĭebuginfo-install kernel # to install necessary "decoder" to analyze the crash fileĬrash /var/crash/./vmcore /usr/lib/debug/lib/modules/./vmlinux # need matching kernel file # -d specify the dump filter (stuff to exclude) VGA may get a spawnedĬore_collector makedumpfile -c -message-level 1 -d 31

It will print output of the kernel core dump result to the stdout device:īut this would mean console boot/shutdown/panic message will no longerīe send to the VGA, but to serial port. Linux kernel panic does not core dump to a file. Ln -sf /lib/systemd/system/rescue.target /etc/systemd/system/default.target Single User Mode RHEL 7 with pxe boot with chrooted env If using GRUB, then, at the menu for choosing kernel, do: To boot into single user mode for maintenance,Įnter "linux single" or "linux emergency" at the LILO boot: prompt. RHEL4 - binary compatible with FC3 (and maybe FC4) RHE元 - binary compatible with FC2 (but FC2 is EOL) Kill script should be placed in rc6.d, which shutdown/reboot scan. If adding a Start script, may want to add them in both in rc3.d and rc5.d, unless it is really only wished to be available at one of the run level and not the other. So, if default init is 5, script in run level 3 would not be run. Scientific Linux has 'fastbugs' and 'security' updates.Oracle Linux (is it still around?) is essentially RHEL, but support is provided from Oracle directly.Lack of action in output does NOT mean security patches aren't needed! See CentOS forum
#CMAKE LINUX FERMILAB UPDATE#
RedHat provides a yum-security plugin that allows machine to be patched with only security update via yum (and keep the OS at the same level).RedHat provides commercial tech support.What is Linux anyway? :)įunny/ugly/stupid chars when pasting? See Ubuntu is conquering the world now, so there are some Debian things here and there. It is RedHat centric.ĬentOS is supposed to be a "rebadged/un-commercialized" version of RHEL, keeping binary-level compatibilities at major release level, thus the discussion should apply equally to CentOS and Scientifi Linux. This Linux guide is my own notes on Linux, for stuff that I did not like toĭocuments that I have found on the internet.
