The Virtual Network Computing (VNC) server allows for a graphical environment to be set up easily by starting the vncserver service. To do so, perform the following steps: ► RHEL 6 configures the VNC server using the /etc/sysconfig/vncservers configuration file. Add a line at the bottom of this file to specify the VNC user: # yum -y install tigervnc-server openmotif xterm xsetroot xorg-x11-xauth ... ► Edit the vncservers file and add one line at the bottom: # cd /etc/sysconfig # vi vncservers ... # VNCSERVERS="2:myusername" # VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost" VNCSERVERS="1:root" ► Set a VNC password with the vncpasswd command. This password will be needed to connect to the VNC server: # vncpasswd Password: lnx4vm Verify: lnx4vm ► Stop the firewall: # service iptables stop iptables: Flushing firewall rules: [ OK ] iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Unloading modules: [ OK ] ► Start the VNC server. This will create some initial configuration files under the /root/.vnc/ directory: # service vncserver start Starting VNC server: 1:root xauth: creating new authority file /root/.Xauthority New 'gpok223.endicott.ibm.com:1 (root)' desktop is gpok223.endicott.ibm.com:1 Creating default startup script /root/.vnc/xstartup Starting applications specified in /root/.vnc/xstartup 122 The Virtualization Cookbook for RHEL 6
Log file is /root/.vnc/gpok223.endicott.ibm.com:1.log [ OK ] ► There is one more configuration to be done. Change from the Tiny window manger, twm, to the Motif window manager, mwm: # cd /root/.vnc # vi xstartup // change last line ... xsetroot -solid grey vncconfig -iconic & xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & mwm & ► Restart the VNC server with the service command: # service vncserver restart Shutting down VNC server: 1:root [ OK ] Starting VNC server: 1:root New 'gpok223.endicott.ibm.com:1 (root)' desktop is gpok223.endicott.ibm.com:1 Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/gpok223.endicott.ibm.com:1.log [ OK ] ► You should now be able to use the VNC client to connect to the IP address of the cloner with a :1 appended. A sample session is shown in Figure 7-14. Figure 7-14 VNC client session to the VNC server Note that the VNC server will not be started automatically across reboots. When you need a graphical environment, you can either to start the vncserver process manually (recommended), or you can use chkconfig to enable automatic startup. 7.2.6 Setting system to halt on SIGNAL SHUTDOWN By default, RHEL 6 reboots when a Ctrl-Alt-Del key sequence is trapped. This key sequence is simulated by z/VM when it issues a SIGNAL SHUTDOWN command. Rather than rebooting, you want your system to halt. To set the system to halt, perform the following steps: Chapter 7. Installing RHEL 6 on the cloner 123
