ERROR: Unable to verify the graphical display setup.
在Linux下安装Oracle时
运行
./runInstaller
报错
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
解决方法:
查了些资料,按照网上的做法:
1.使用root用户执行xhost +操作;
2.直接用oracle用户登陆(不是通过root切换),然后执行export DISPLAY=本地ip:0.0;
试过多次发现仍然不能解决问题,回过头再看报错:/xdpyinfo,试着执行xdpyinfo:
java
[oracle@linux-oracle6 ~]$ cd /usr/bin/xdpyinfo
-bash: /usr/bin/xdpyinfo: No such file or directory
发现该命令不存在,开始怀疑是xdpyinfo问题,于是安装xdpyinfo:
java
[root@linux-oracle6 ~]# yum -y install xdpyinfo
vncserver
java
root@localhost ~]# vncserver
New 'localhost:1 (root)' desktop is localhost:1
Starting applications specified in /root/.vnc/xstartupLog file is /root/.vnc/localhost:1.log
java
export DISPLAY=localhost:1
java
xhost +
access control disabled, clients can connect from any host
出现上面提示即可。再次运行
java
./runInstaller
若是运行上述命令的时候,提示没有vncserver这个命令,则执行:
java
yum install tigervnc-server
若是提示没有xhost,则执行:
java
yum whatprovides "*/xhost" ----------------------查看是哪些提供了 */xhost

安装xorg-x11-server-utils-7.7-2.el6.x86_64
java
yum -y install xorg-x11-server-utils-7.7-2.el6.x86_64
这样这两个命令就都可以用啦。
