安装domino6.0.3第一次启动出错

befeel

错误信息如下：

./java -ss512k -Xoss5M -cp jhall.jar:cfgdomserver.jar:Notes.jar lotus.domino.setup.WizardManagerDomino -data /dominodata/notesdata Xlib: connection to ":0.0" refused by server Xlib: Client is not authorized to connect to Server Please edit your shell's DISPLAY environment variable to reflect an unlocked terminal that you would like to launch the Domino Setup Program on. *Warning all runtime debug

按照CU的书册export DISPLAY＝$HOSTNAME:0.0  xhost +
了，还是不行。
报以下错误：
Xlib: connection to ":0.0" refused by server Xlib: Client is not authorized to connect to Server 1356-200 xhost unable to open display ":0.0"


该咋整呢
