RPM/YUM 進階語法~將 CentOS 移轉成 Scientific Linux

在不重新安裝整個系統下，將既有的 CentOS 6.x 轉換成 Scientific Linux。

rpm -ivh http://ftp.scientificlinux.org/linux/scientific/6x/i386/os/Packages/yum-conf-sl6x-1-2.noarch.rpm
processor=`uname -i`
centos=${processor:1:3}
if [ $centos != 386 ] ; then
rpm -ivh --force http://ftp.scientificlinux.org/linux/scientific/6x/x86_64/os/Packages/sl-release-6.5-1.x86_64.rpm
else
rpm -ivh --force http://ftp.scientificlinux.org/linux/scientific/6x/i386/os/Packages/sl-release-6.5-1.i686.rpm
fi
sed -i 's|centos-release|sl-release|' /etc/yum.conf
sed -i 's|exclude=centos|\#exclude=centos|' /etc/yum.conf
yum -y erase centos-release
yum -y clean all
yum -y distro-sync
yum -y reinstall `rpm -qa --qf "%{NAME} %{VENDOR}\n"|grep CentOS|awk '{print $1}'`
cd /boot/grub
mv splash.xpm.gz /root/splash.xpm.gz.centos
wget http://pbxinaflash.com/splash.xpm.gz
chmod 644 splash.xpm.gz
chattr -i /etc/pbx/.version
echo "3.0.6.5" > /etc/pbx/.version
chattr +i /etc/pbx/.version
reboot
