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.

Answer 1

更好的是我们可以尝试使用 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。您可以在屏幕上显示时钟。收到时钟后，然后运行安装命令。

最后，将安装 webLogic 服务器。
