关于grid安装的一些错误_make sure that xdpyinfo exist under path variable.-优快云博客

本文档详细记录了在Linux环境中安装Oracle时遇到的两个问题及其解决方案。首先，由于缺少Xdisplay，安装过程无法验证图形设置，通过安装xorg-x11-utils包解决了该问题。然后，perl运行时找不到libnsl.so.1库，通过yum install libnsl修复。完成这些步骤后，确保不再有错误并能顺利进行Oracle的安装。

1、This application requires X display

ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.

解决方式：oracle安装图形显示依赖X display，需安装xorg-x11-utils包，按以下方式安装后验证。

[root@grid1-dahouzi-cn LINUX.X64_193000_grid_home]# ./gridSetup.sh
