► Import the RPM GPG key so that yum knows you are installing official Red Hat packages. The Red Hat GPG key is located in the install tree. Import the key with the following command: # rpm --import /nfs/rhel6/RPM-GPG-KEY-redhat-release The yum tool should now be configured. It will be tested in the next section. 8.2.3 Turning off unneeded services As with the golden image, follow the steps in 7.2.4, “Turning off unneeded services” on page 121. Following is a summary: # chkconfig iptables off # chkconfig ip6tables off # chkconfig auditd off # chkconfig abrtd off # chkconfig atd off # chkconfig mdmonitor off Verify these service are turned off with the chkconfig --list command: # chkconfig --list | grep 3:on autofs 0:off 1:off 2:off 3:on 4:on 5:on 6:off cpi 0:off 1:on 2:on 3:on 4:on 5:on 6:off cpuplugd 0:off 1:off 2:on 3:on 4:on 5:on 6:off crond 0:off 1:off 2:on 3:on 4:on 5:on 6:off dumpconf 0:on 1:on 2:on 3:on 4:on 5:on 6:on haldaemon 0:off 1:off 2:off 3:on 4:on 5:on 6:off lvm2-monitor 0:off 1:on 2:on 3:on 4:on 5:on 6:off messagebus 0:off 1:off 2:on 3:on 4:on 5:on 6:off mon_statd 0:off 1:off 2:on 3:on 4:on 5:on 6:off netfs 0:off 1:off 2:off 3:on 4:on 5:on 6:off network 0:off 1:off 2:on 3:on 4:on 5:on 6:off nfslock 0:off 1:off 2:off 3:on 4:on 5:on 6:off postfix 0:off 1:off 2:on 3:on 4:on 5:on 6:off rhnsd 0:off 1:off 2:on 3:on 4:on 5:on 6:off rpcbind 0:off 1:off 2:on 3:on 4:on 5:on 6:off rpcgssd 0:off 1:off 2:off 3:on 4:on 5:on 6:off rpcidmapd 0:off 1:off 2:off 3:on 4:on 5:on 6:off rsyslog 0:off 1:off 2:on 3:on 4:on 5:on 6:off sshd 0:off 1:off 2:on 3:on 4:on 5:on 6:off sysstat 0:off 1:on 2:on 3:on 4:on 5:on 6:off udev-post 0:off 1:on 2:on 3:on 4:on 5:on 6:off 8.2.4 Configuring the VNC server Configure the VNC server the same way as on the cloner. Follow the same steps as described in 7.2.5, “Configuring the VNC server” on page 122. 8.2.5 Setting system to halt on SIGNAL SHUTDOWN Again, RHEL 6 reboots when a Ctrl-Alt-Del key sequence is trapped. This key sequence is simulated by z/VM when a SIGNAL SHUTDOWN command is issued. Rather than rebooting, you want your system to halt (shutdown). Edit /etc/init/control-alt-delete.conf changing shutdown -r (reboot) to shutdown -h (halt): 140 The Virtualization Cookbook for RHEL 6
# cd /etc/init # vi control-alt-delete.conf # control-alt-delete - emergency keypress handling # # This task is run whenever the Control-Alt-Delete key combination is # pressed. Usually used to shut down the machine. start on control-alt-delete exec /sbin/shutdown -h now "Control-Alt-Delete pressed" This change will be picked up when the system is rebooted. 8.2.6 Setting the system to logoff when Linux is shut down When Linux is shut down, the default is for the virtual machine to remain logged on even though it is not running an operating system. It is more convenient for the user ID to be logged off, both at z/VM SHUTDOWN time and for getting a refreshed 3270 emulator session. To do this, perform the following steps: ► Edit the file /etc/rc.d/rc.local and add two lines at the end as follows: # cd /etc/rc.d # vi rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local chshut halt vmcmd logoff chshut poff vmcmd logoff The z/VM user ID should now be logged off when you halt or power off Linux. 8.2.7 Configuring SSH keys Recall that you generated SSH keys on the cloner in 7.2.8, “Configuring SSH keys” on page 125. Now it is time to copy these keys from the cloner to the golden image. ► Create a new directory (if one doesn’t already exist) on the golden image where the public key will be copied: # cd /root # mkdir .ssh ► Set the permissions to 700 so that it can only be accessed by root: # chmod 700 .ssh ► Copy the public key to the name authorized_keys using the secure copy command scp: # scp 9.60.18.223:/etc/ssh/ssh_host_dsa_key.pub /root/.ssh/authorized_keys The authenticity of host '9.60.18.223 (9.60.18.223)' can't be established. RSA key fingerprint is c7:d6:3b:8c:20:57:06:fc:8c:71:80:a5:4f:72:47:38. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '9.60.18.223' (RSA) to the list of known hosts. root@9.60.18.223's password: ssh_host_dsa_key.pub 100% 590 0.6KB/s 00:00 Chapter 8.
