PS: you can download passwd and xstartup here vnc-config-passwd (wel*1). Or you can set password through use vncpasswd ~/.vnc/passwd

mkdir -p ~oracle/.vnc
wget --no-proxy http://test/iso/HostConfiguration/vnc/passwd -P ~oracle/.vnc/
wget --no-proxy http://test/iso/HostConfiguration/vnc/xstartup -P ~oracle/.vnc/

chkconfig --level 345 vncserver on
chkconfig --list | grep vncserver
service vncserver start

PS: You can change vncserver's resolution through editing /usr/bin/vncserver, change the default "$geometry = "1024x768";" to any one you like, for example "$geometry = "1600x900";". You can also control each user's vnc resolution setting through adding line like "VNCSERVERARGS[1]="-geometry 1600x900"" in /etc/sysconfig/vncservers
