Xlib: connection to ":0.0" refused by server

本文介绍在RedHat AS5系统中安装Oracle时遇到的图形界面连接拒绝问题及解决方案。通过设置X主机权限,允许指定用户访问本地X服务器,成功解决了安装过程中的图形界面连接问题。

在redhat as5下安装oracle,进入database目录运行./runInstaller时,系统提示:

#Xlib: connection to ":0.0" refused by server

Xlib: No protocol specified

解决方法:

登陆该图形界面的宿主用户,输入

#xhost +local:username

其中,username为运行./runInstaller命令的用户。

 

解释一下:

xhost是用来控制 Xserver访问权限的如果A登陆到B上运行B的应用程序,作为应用程序来说,A是client,但是作为图形界面来说,是在A上显示的,需要使用A的Xserver.所以A是server,因此,在登陆到B前,需要在A上运行xhost +来使其它用户访问A的X server
#xhost +local:username
username是指B的用户名称

To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command: % xhost + To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as 'xclock': % <full path to xclock.. see below> If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance. Typical path for xclock: /usr/X11R6/bin/xclock
