CentOS 6.3 i386

You can install this distro in your appliance.

Note: We recommend creating a separate partition for /usr volume to allow you to move the volume later. This allows you to create a volume that is read-only and shared between appliance instances as well as conserve disc space. You must verify that the distro that you are installing supports the separation. If you create multiple partitions and do not separate later, some filesystem counters will not report correctly.

Follow these steps:

Upload the installation DVD to the /vol/_impex/ directory.

Open the grid shell and initialize the installation with the following command:

util iso2class app_name=CentOS63_i386 install_size=5G console_type=graphic iso_volume1=CentOS-6.3-i386-bin-DVD1.iso os=linux virt_mode=xen_pv,xen_hvm  cpu=0.5 mem=1.5G bw=1M

The following prompt displays:

When you have finished installing from iso_volume1 and are ready to reboot so that remaining volume(s) become available, press [Enter]

Access the AppLogic GUI, select the CentOS63_i386 application, and click the Login (graphic) icon.

cat > /etc/init/ttyS0.conf <<END
stop on runlevel [S016]
start on runlevel [23]
