Manual contextualisation

Package installation

• Cloud specific: openssh, openssh-server, openssh-clients (for ssh), acpid (for the machine shutdown)
• Virtual cluster: rpcbind (or portmap), nfs-utils

Running services

To allow acpid:

$ service acpid start
$ service acpid status

stratuslab-one-context package installation

$ rpm -i http ://yum.stratuslab.eu/snapshots/fedora14/stratuslab-one-context-
2.1-0.20121004.192530.noarch.rpm

Files modifications

• Linking the virtual disk of the Cloud and the cdrom:

$ vi /etc/stratuslab/stratuslab-one-context.cfg
context_device=sr0 

(or hdd)

• Specifying the control of the ssh VM connexion:

$ vi /etc/ssh/sshd_config
PasswordAuthentication no
ChallengeResponseAuthentication no
GSSAPIAuthentication no
PermitRootLogin without-password

• Managing the partition:

$ vi /etc/fstab 

If necessary, remove the cdrom line.
Add a line for the swap disk:

/dev/sdb swap swap defaults 0 0

• Removing MAC adress informations and eth0 interface informations:

$ rm /etc/udev/rules.d/70-persistent-net.rules
$ rm /etc/udev/rules.d/70-persistent-cd.rules

• Removing MAC adress number:

$ vi /etc/sysconfig/network-scripts/ifcfg-eth0

HWADDR

• Allowing SSH connexion:

$ vi /etc/selinux/config
SELINUX = disabled

Verifications

• Choosing a random Root password:

vi /etc/stratuslab/conf.d/password.context
enable=yes
