2.創建快捷啟動

   創建快捷啟動服務：

   #cd /etc/init.d

   #touch xvfbd

   #vim xvfbd

#!/bin/bash
#
# /etc/rc.d/init.d/xvfbd
#
# chkconfig: 345 95 28
# description: Starts/Stops X Virtual Framebuffer server
# processname: Xvfb
#
 
. /etc/init.d/functions
 
[ "${NETWORKING}" = "no" ] && exit 0
 
PROG="Xvfb"
PROG_OPTIONS=":7 -ac -screen 0 1024x768x24"
PROG_OUTPUT="/tmp/Xvfb.out"
 
case "$1" inr
    start)
        echo -n "Starting : X Virtual Frame Buffer "
        $PROG $PROG_OPTIONS>>$PROG_OUTPUT 2>&1 &
        disown -ar
        /bin/usleep 500000
        status Xvfb & >/dev/null && echo_success || echo_failure
        RETVAL=$?
        if [ $RETVAL -eq 0 ]; then
            /bin/touch /var/lock/subsys/Xvfb
            /sbin/pidof -o  %PPID -x Xvfb > /var/run/Xvfb.pid
        fi
        echo
        ;;
    stop)
        echo -n "Shutting down : X Virtual Frame Buffer"
        killproc $PROG
        RETVAL=$?
        [ $RETVAL -eq 0 ] && /bin/rm -f /var/lock/subsys/Xvfb /var/run/Xvfb.pid
        echo
        ;;
    restart|reload)
        $0 stop
        $0 start
        RETVAL=$?
        ;;
    status)
        status Xvfb
        RETVAL=$?
        ;;
    *)
     echo $"Usage: $0 (start|stop|restart|reload|status)"
     exit 1
esac
 
exit $RETVAL

  啟動服務：

  #chmod +x /etc/init.d/xvfbd

  #chkconfig xvfbd on

  #service xvfbd start
