Installation Zope2.7

1. Python 2.3 installieren:
erster Versuch schlug Fehl !!! rpm --import redhat-key
yum install rpm-build
rpm -ihv /var/cache/yum/redhat-os/packages/rpm-build-4.2-0.69.i386.rpm
yum install patch
yum install expat-devel
yum install db4-devel
yum install gdbm-devel
yum install gcc
yum install gcc-c++ compat-gcc-c++ compat-gcc
rpmbuild --rebuild python2.3-2.3.4-3pydotorg.src.rpm

Zweiter Versuch mit Fedora core 1 binary
wget http://www.python.org/ftp/python/2.3.4/rpms/fedora-1/python2.3-2.3.4-3pydotorg.i386.rpm
wget ftp://194.199.20.114/linux/fedora/core/1/i386/os/Fedora/RPMS/db4-4.1.25-14.i386.rpm
rpm -ivh db4-4.1.25-14.i386.rpm
rpm -ivh python2.3-2.3.4-3pydotorg.i386.rpm
wget http://www.python.org/ftp/python/2.3.4/rpms/fedora-1/python2.3-devel-2.3.4-3pydotorg.i3
sudo rpm -ihv python2.3-devel-2.3.4-3pydotorg.i386.rpm

Setup DB from Backup

mysqladmin -u root -p create nccr
mysql -u root -p --database=nccr < 2004-11-22-yellowpages.dump
mysqladmin -u root -p create helium
mysql -u root -p --database=helium < 2004-11-22-helium.dump

RAID hot ...

raidhotremove /dev/md1 /dev/hde2
raidhotadd /dev/md1 /dev/hde2

RAID Disk austauschen

1.) Disk aus dem RAID
raidhotremove /dev/md1 /dev/hde2
2.)neue DISK gleich partitionieren wie disk im RAID
partitionieren der DISK (ACHTUNG):
fdisk /dev/hdg

3.) Disk hotadd
raidhotadd /dev/md0 /dev/hdg3
raidhotadd /dev/md1 /dev/hdg2
raidhotadd /dev/md2 /dev/hdg1
4.) SWAP einrichten
mkswap /dev/hdg5
swapon -s
swapon
