The following high level steps are recommended though you may add or omit some steps: ► “Configuring automount of install tree” on page 138 ► “Configuring yum for online updates” on page 139 ► “Turning off unneeded services” on page 140 ► “Configuring the VNC server” on page 140 ► “Setting system to halt on SIGNAL SHUTDOWN” on page 140 ► “Setting the system to logoff when Linux is shut down” on page 141 ► “Configuring SSH keys” on page 141 ► “Changing the order of the swap disks” on page 142 ► “Rebooting the system” on page 142 ► “Verifying the changes” on page 143 8.2.1 Configuring automount of install tree You will now configure the Linux automount service to mount the installation tree on demand. The automounter will automatically mount a remote directory when it is accessed, and automatically unmount it after a period of inactivity. To configure automount, perform the following steps: ► Make a backup copy of the file /etc/auto.master, then add the following line at the bottom: 138 The Virtualization Cookbook for RHEL 6
# cd /etc # cp auto.master auto.master.orig # vi auto.master // add one line at the bottom ... # +auto.master /nfs /etc/auto.cloner ► The new line specifies that the file system mounted beneath the directory /nfs/ will be configured in the file /etc/auto.cloner. Now create the file /etc/auto.cloner, and add one line which points to the RHEL 6 install tree that is NFS-exported from the cloner: # vi auto.cloner rhel6 -ro,hard,intr 9.60.18.223:/nfs/rhel6 This line specifies that beneath /nfs/ (in auto.master), when the directory rhel6/ (field 1) is accessed, the automounter will use the specified options (field 2) to mount the directory (field 3). ► Create the /nfs/ directory. Restart the autofs service to pick up the new configuration. Then list the contents of the /nfs/rhel6/ directory. Even though this directory does not exist as a local file system, it is automatically mounted when referenced: # mkdir /nfs # service autofs reload Reloading maps ► Show that the directory /nfs/rhel6/ is automatically mounted: # ls /nfs/rhel6 boot.cat RELEASE-NOTES-es-ES.html RELEASE-NOTES-pt-BR.html EULA RELEASE-NOTES-fr-FR.html RELEASE-NOTES-ru-RU.html ... 8.2.2 Configuring yum for online updates You will now configure yum so it can install RPMs from the automount-ed install tree. The configuration is identical to the cloner because in both instances the install tree is in the directory /nfs/rhel6/. However on the cloner this directory is local, while on the golden image (and later the clones) the directory is automount-ed. To configure yum, perform the following steps: ► You could create a file named rhel6.repo in the /etc/yum.repos.d directory again, or you could copy the same file from the cloner that you created previously. In this example scp is used to copy the file: # cd /etc/yum.repos.d # scp gpok223:/etc/yum.repos.d/rhel6.repo . The authenticity of host 'gpok223 (9.60.18.223)' can't be established. RSA key fingerprint is 37:5f:83:99:ba:9e:10:14:04:65:06:e1:11:d9:d9:cd. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'gpok223,9.60.18.223' (RSA) to the list of known hosts. root@gpok223's password: rhel6.repo 100% 73 0.1KB/s 00:00 ► Type the file to verify the contents: # cat rhel6.repo [RHEL6] name=Red Hat Enterprise Linux 6 baseurl=file:///nfs/rhel6/Server Chapter 8.
