Fedora is the test ground for all things that might wander into the next generation of RHEL.

[edit] Notes

  • you can get more suff by enabling the Dries repository, which you can do by adding this stuff to your /etc/yum.conf file (mine has it already there, just commented out 
 [dries]
 name=Extra Fedora rpms dries - $releasever - $basearch
 baseurl=http://ftp.belnet.be/packages/dries.ulyssis.org/fedora/linux/$releasever/$basearch/dries/RPMS/

     [dries]
     name=Extra Fedora rpms dries - $releasever - $basearch
     baseurl=http://ftp.belnet.be/packages/dries.ulyssis.org/fedora/linux/$releasever/$basearch/dries/RPMS/
     enabled=1
     gpgcheck=1

Be sure there is a carriage return (blank line) at the bottom of the file. Click the "save" icon in gedit and then close gedit.

  • While still in the root terminal type: 
 rpm --import http://freshrpms.net/packages/RPM-GPG-KEY.txt

Hit enter. You have just imported the GPG key for the freshrpms repository.

  • Also type: 
 rpm --import http://apt.sw.be/dries/RPM-GPG-KEY.dries.txt

Hit enter. You have just imported the GPG key for the dries repository.

  • Type: 
 yum -y update

Hit enter. Your system will be updated. Reboot your machine.

  • Note: You can temporarily disable a troublesome repository with a command such as, for example "yum -y --disablerepo updates update" as root. This is especially useful if you get the message "No more mirrors to try..." which occurs occasionally when the mirrors are very busy or down. To clean your repository data and get a fresh list of updates do a "yum clean all" followed by a "yum -y update" as root. Please see the official Fedora Core Yum guide at http://fedora.redhat.com/docs/yum/ for more details about Yum and its configuration. (Tip: Some users have reported better success with yum updates if they edit the repository files in the /etc/yum.repos.d directory and remove the comment mark ("#") from the beginning of the "baseurl=" lines, especially if they are getting "Error: Cannot find a valid baseurl for repo:" errors.)
[edit] Yum
cat /etc/redhat-release shows what version you're running
chkconfig --level 345 httpd on apache will automatically start when rebooted
chkconfig --list lists what starts up on boot
killall -9 yum kills yum when it hangs
rpm -q --whatprovides libapr-1.so.0 finds out what packages will install libapr-1.so.0
rpm -Uvh --test php-4.4.6-2.rs.rhel4.i386 does a test install to let you know if there are problems
service httpd start starts apache, kind of like doing /etc/init.d/httpd start
yum install rpm-build allows you to build your own rpms
yum whatprovides libpam searches yum repository for packages that include libpam library
[edit] Compile Kernel from Sources

Fedora Core 6, might work on others, but don't be stupid. A good chunk of this taken for several sources, but a pretty good one is here http://menkou.homelinux.net/serendipity/index.php?/archives/19-Fedora-Core-6-kernel-compile.html

yum install kernel-devel installs the kernel headers, useful if you want to just install a driver or something, otherwise you'll have to compile the kernel, as outlined below.
lynx http://mirrors.kernel.org/fedora/core/6/source/SRPMS/ select the latest kernel and then download it
mkdir -p /usr/src/redhat/SRPMS/
mv kernelxxxxxxxx.srx.rpm /usr/src/redhat/SRPMS
yum install yum-utils gets yum set up to download src stuff
yum gcc installs the gcc compiler
yum install ncurses-devel enables make menuconfig to work
yumdownloader --source kernel --enablerepo core-source --enablerepo updates-source enables src repos
rpmbuild -bp --target=$(uname -m) /usr/src/redhat/SPECS/kernel-2.6.spec builds rpm
cd /usr/src/redhat/BUILD/kernel-2.6.18/linux-2.6.18.i686 this is where the patched kernel source lives
make menuconfig configures build options, Look under Security Options > Default Linux Capabilities <M> (it probably was checked with a * , then hit esc twice to save
make modules_install sets up the modules to load right
make builds stuff, go eat lunch, it'll be done when you get back...hopefully
modprobe commoncap you need this before dazuko will work, otherwise it will give you a 'dazuko.ko': -1 Unknown symbol in module
cd /usr/src/dazukoxxx
/usr/sbin/insmod dazuko.ko inserts dazuko as a kernel module
vi /etc/init.d/esets_daemon insert these 2 lines right below the comments at the top of the file, before the "PATH" command
modprobe commoncap
insmod /usr/src/dazuko-2.3.3/dazuko.ko
vim /etc/esets/esets.cfg enable the dazuko section
yum install rpm-build allows you to build your own rpms
yum install redhat-rpm-config allows you to config the rpm while building it
