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.

我正在寻找这个错误的解决方案。

Answer 1

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。

Answer 2

我刚刚进行了最小安装以获得全新的环境，并在安装 WebLogic 时遇到了这条消息。由于这是谷歌的第一次点击，我在这里发布解决方案。

需要安装X11服务器及相关包

yum install -y xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps xorg-x11-utils xclock
systemctl restart sshd

DISPLAY 环境变量设置了一组不完整的 RPM，这是误导性的。

如果您使用的是 PuTTY，那么您还应该安装并运行 XMing。
