问题描述

安装 weblogic 服务器时，出现此错误。我已经尝试了很多，但我无法解决它。

我通过以下命令尝试过，

# xhost +

yum install xorg-x11-xauth

我按照这里给出的步骤进行操作。https://superuser.com/questions/119792/how-to-use-x11-forwarding-with-putty

DISPLAY is not set.  Please set the DISPLAY environment variable and try again.
Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:
- For csh:                      %% setenv DISPLAY 192.168.1.128:0.0
- For sh, ksh and bash:         $ DISPLAY=192.168.1.128:0.0; export DISPLAY
Use the following command to see what shell is being used:
echo $SHELL
Use the following command to view the current DISPLAY environment variable setting:
echo $DISPLAY
- Make sure that client users are authorized to connect to the X Server.
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

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

解决方案

更好的是我们可以尝试mobaXterm而不是PUTTY.

在mobaXterm中，获取 Xserver 值并使用以下命令运行。

例如， export DISPLAY=192.168.0.106:0.0

然后，试试这个xclock命令。您可以在屏幕上获取时钟。一旦您收到时钟，然后运行安装命令。

最后，将安装 webLogic 服务器。
