Implementation Notes

Base Class

LUX64 is a base class, it is build on a physical server and then the volumes are pushed into the appliance.

Class Volumes

The boot volume LUX64 is based on 64-bit CentOS 5. Below is a list of the software packages installed on LUX64.

Re-install Procedure

Here are the steps needed to create a LUX64 (tested on applogic 2.2.0)

Install centos 5 on a physical server from th efirst cd with this ks file (network configuration and root password should be changed). To use the ks file, type on the centos boot prompt: linux text ks=hd:sdb1/ks.cfg . This example assumes that you have the ks.cfg file on a separate disk (usb pendrive also works), you can boot the file from the cd (you need to rebuild the cd) or from the network

After the installation is complete, login the the server and do

   cp -a /{bin,boot,dev,etc,home,lib,lib64,media,opt,root,sbin,srv,usr,var} /mnt/
   mkdir /mnt/{mnt,proc,sys,tmp}
   chmod 755 /mnt/mnt /mnt/sys/
   chmod 555 /mnt/proc/
   chmod 1777 /mnt/tmp/
   rpm --root /mnt -e audit-libs-python authconfig policycoreutils selinux-policy selinux-policy-targeted setools checkpolicy kernel-headers cryptsetup-luks dbus-glib hal kudzu Deployment_Guide-en-US dhclient dhcpv6_client dmidecode hdparm hwdata iptables iptables-ipv6 kbd  libgcrypt libgpg-error libusb libxml2 libxml2-python pciutils pm-utils  prelink rhpl rootfiles setserial system-config-securitylevel-tui tcl wireless-tools dbus 
   rpm --root /mnt -e kernel
   rpm --root /mnt --allmatches -e nash lvm2 dmraid grub  kpartx lvm2 mkinitrd nash redhat-logos

install xen DomU kernel and modules. The actual package versions will depend on the applogic version. The example below is for applogic 2.2, use the rpms that come in the applogic install directory for the current release
```
   rpm --root /mnt -Uv  xen-ukrnl-3.2-1.x86_64.rpm  xen-umods-3.2-1.x86_64.rpm
   
```
Configure log rotation
- edit /mnt/etc/logrotate.conf and set 'size 512k' and ensure rotate is set to 4

Cleanup

   chroot /mnt rpm -v --rebuilddb
   rm -f /mnt/root/anaconda-ks.cfg /mnt/root/install.log /mnt/root/install.log.syslog /mnt/root/.lesshst
   rm -rf /mnt/usr/share/doc/*
   rm -rf /mnt/usr/share/man/*
   rm -rf /mnt/boot/grub
   find /mnt/var/log/ -type f -exec rm -f {} \;
   rm -f /mnt/etc/sysconfig/network-scripts/ifcfg-eth*
   rm -f /mnt/etc/sysconfig/network-scripts/route-eth*
   echo -n "" > /mnt/etc/resolv.conf
   echo "127.0.0.1 localhost.localdomain localhost" > /mnt/etc/hosts
   touch /mnt/etc/applogic_network.conf
   cd /mnt/usr/lib/locale/ && for dir in *; do [ ! "$dir" == "en_US" ] && [ ! "$dir" == "en_US.iso885915" ] && [ ! "$dir" == "en_US.utf8" ] && rm -rf $dir; done
   cd /mnt/usr/share/locale/ && for dir in *; do [ ! "$dir" == "en" ] && [ ! "$dir" == "en_GB" ] && [ ! "$dir" == "en_US" ] && rm -rf $dir; done

Copy files %NOTE: The atached files are part of applogic 2.2.0, you should get the files from the latest applogic version.
- /appliance/appliance.sh
- /appliance/ccad
- /appliance/vma_ctl.sh
- /appliance/vmad
- /appliance/vme
- /etc/init.d/applogic_appliance
- /etc/init.d/applogic_cca
- /etc/init.d/applogic_network
- /etc/init.d/applogic_vma
- /boot/initrd-2.6.18-xenU.img (copy from a dom0 server in a grid from the current version)

Setup init scripts

   chroot /mnt chkconfig --add applogic_appliance
   chroot /mnt chkconfig --add applogic_cca
   chroot /mnt chkconfig --add applogic_network
   chroot /mnt chkconfig --add applogic_vma

Change files
1. Edit fstab
  - /etc/fstab
2. Disable password logins and PAM in sshd config
  - /etc/ssh/sshd_config
3. Enable arp_ignore
  - /etc/sysctl.conf
4. Fix applogic prompt
  - /root/.bash_profile
  - /root/.bashrc
5. Disable ttys > 1
  - /etc/inittab

Create images

   dd if=/dev/zero of=/tmp/LUX64.boot.img bs=1k seek=290k count=1k
   dd if=/dev/zero of=/tmp/LUX64.usr.img bs=1k seek=290k count=1k
   mkfs -t ext3 -F /tmp/LUX64.usr.img
   mkfs -t ext3 -F /tmp/LUX64.boot.img
   mount -o loop /tmp/LUX64.usr.img /media/
   mv /mnt/usr/* /media/
   umount /media/
   mount -o loop /tmp/LUX64.boot.img /media/
   mv /mnt/* /media/
   umount /media/
   gzip /tmp/LUX64.usr.img
   gzip /tmp/LUX64.boot.img

Crate an application in EDT named myapp
add a new singleton
Edit:
- name: LUX64
- Category: Generic
- Description: Generic 64-bit Centos 5-based appliance (version 0.0.1)
- kernel + initrd: /boot/vmlinuz-2.6.18-xenU, /boot/initrd-2.6.18-xenU.img
- terminals: add mon out terminal (proto cce, not mendatory)
- volumes:
  - boot, instantiable, mount on /dev/hda1, 300M, fs: ext3, boot
  - usr, type common, mount on /dev/hda2, 300M, fs: ext3, shared, ro
  - resources: see data sheet
export application
```
app export myapp myapp
```

upload new images to the vol directory of your exported application

   # Example:
   sftp -o 'StrictHostKeyChecking no' -o "IdentitiesOnly yes"  -o "IdentityFile ~/.ssh/applogic" root@ev1.3tera.net:/_impex/myapp/vol
   # on the command prompt
   put LUX64.usr.img.gz
   put LUX64.boot.img.gz

import the application with the new volumes
```
app import myapp2 myapp
```

resize volumes

   vol resize myapp2:LUX64.boot size=110M
   vol resize myapp2:LUX64.usr size=140M

Move to catalog
```
class move  myapp2:LUX64 /user:LUX64
```
