Base install
- Install CentOS 5 bare-bones
- Setup LDAP authentication (see this guide)
- add ldap to /etc/nsswitch.conf's passwd, shadow and group entries
- configure /etc/ldap.conf according to this
- make sure the DutchGrid CA certificate is in /etc/openldap/cacerts/16da7552.0 (from rpm or here)
- update /etc/pam.d/system-auth using command authconfig --enableldap --enableldapauth --update
- create homedirs for your users as /user/<username> with correct owner, populate authorized_keys
- disable ssh PasswordAuthentication
Master
- Install and configure OpenNebula
- Setup dynamic DNS
- install and configure bind
- create OpenNebula hooks with ddns-update script
- Setup image repository
OpenNebula documentation Building Clouds presentation Virtual Machines working group
Slaves
- Enable Xen (see also Xen on CentOS 5)
- yum install xen kernel-xen
- make grub boot Xen kernel by default (change default in /boot/grub/menu.lst), add nosmp to kernel cmdline and reboot
- Allow oneadmin user to execute cloud-related commands using sudo
- Setup /etc/sudoers (e.g. using visudo)
- Cmnd_Alias CLOUD = /usr/sbin/xm, /usr/sbin/xentop, /usr/sbin/lvs, /usr/sbin/lvcreate, /usr/sbin/lvremove, /bin/dd
- oneadmin ALL = NOPASSWD: CLOUD
- Disable sudo's requiretty option
- Add PATH=$PATH:/sbin:/usr/sbin to ~oneadmin/.bashrc so that these commands can be found
- Setup /etc/sudoers (e.g. using visudo)
- Install ruby from the RubyWorks repository (you really need 1.8.6 or higher)
- Enable passwordless ssh login from master for oneadmin user
- Add to master using onehost there
