怎么样解决Oracle 11g安装中出现xhost:unable to open display的问题？
怎么样解决Oracle 11g安装中出现xhost:unable to open display的问题？
一、Xhosts报错
安装好vncserver，本地pc笔记本能通过vnc viewer远程连接Oracle服务器，但是在执行xhost+报错，尝试过localhost，尝试过127.0.0.1，也试过本机ip地址，都是unable toopen displa，如下所示
[root@orcltest ~]# export DISPLAY=localhost:1 [root@orcltest ~]# xhost xhost: unable to open display "localhost:1" [root@orcltest ~]# [root@orcltest ~]# export DISPLAY=127.0.0.1:1 [root@orcltest ~]# xhost xhost: unable to open display "127.0.0.1:1" [root@orcltest ~]# xhost + xhost: unable to open display "127.0.0.1:1" [root@orcltest ~]# xhost + 192.51.3.12 xhost: unable to open display "192.51.3.12:1"
二、去查看后台的vnc日志信息，日志信息，看到vnc日志信息正常，没有啥异常信息
[root@orcltest ~]# vim /root/.vnc/orcltest:1.log Xvnc TigerVNC 1.1.0 - built May 11 2016 13:01:55 Copyright (C) 1999-2011 TigerVNC Team and many others (see README.txt) See http://www.tigervnc.org for information on TigerVNC.

三、试试xdyinfo
Google到了一些资料，有准备安装xdyinfo成功的，这里也试试看，先安装xdpyinfo
[root@orcltest ~]# xdpyinfo -bash: xdpyinfo: command not found [root@orcltest ~]# yum install -y xdpyinfo Loaded plugins: refresh-packagekit, security Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package xorg-x11-utils.x86_64 0:7.5-14.el6 will be installed --> Processing Dependency: libdmx.so.1()(64bit) for package: xorg-x11-utils-7.5-14.el6.x86_64 --> Processing Dependency: libXxf86dga.so.1()(64bit) for package: xorg-x11-utils-7.5-14.el6.x86_64 --> Running transaction check ---> Package libXxf86dga.x86_64 0:1.1.4-2.1.el6 will be installed ---> Package libdmx.x86_64 0:1.1.3-3.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================================================================================================================================================== Package Arch Version Repository Size =============================================================================================================================================================================================================================================================================== Installing: xorg-x11-utils x86_64 7.5-14.el6 base 101 k Installing for dependencies: libXxf86dga x86_64 1.1.4-2.1.el6 base 18 k libdmx x86_64 1.1.3-3.el6 base 15 k Transaction Summary =============================================================================================================================================================================================================================================================================== Install 3 Package(s) Total download size: 133 k Installed size: 270 k Downloading Packages: (1/3): libXxf86dga-1.1.4-2.1.el6.x86_64.rpm | 18 kB 00:00 (2/3): libdmx-1.1.3-3.el6.x86_64.rpm | 15 kB 00:00 (3/3): xorg-x11-utils-7.5-14.el6.x86_64.rpm | 101 kB 00:00 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 252 kB/s | 133 kB 00:00 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : libXxf86dga-1.1.4-2.1.el6.x86_64 1/3 Installing : libdmx-1.1.3-3.el6.x86_64 2/3 Installing : xorg-x11-utils-7.5-14.el6.x86_64 3/3 Verifying : libdmx-1.1.3-3.el6.x86_64 1/3 Verifying : xorg-x11-utils-7.5-14.el6.x86_64 2/3 Verifying : libXxf86dga-1.1.4-2.1.el6.x86_64 3/3 Installed: xorg-x11-utils.x86_64 0:7.5-14.el6 Dependency Installed: libXxf86dga.x86_64 0:1.1.4-2.1.el6 libdmx.x86_64 0:1.1.3-3.el6 Complete! [root@orcltest ~]#
之后再执行xdpyinfo，可以xhsot +成功，如下所示，就可以启动./runInstaller安装oracle了。
[root@orcltest ~]# xdpyinfo xdpyinfo: unable to open display "localhost:1". [root@orcltest ~]# xhost + 192.51.3.12 Xhost: unable to open display "localhost:1" [root@orcltest ~]# export DISPLAY=:1.0 [root@orcltest ~]# xhost + access control disabled, clients can connect from any host [root@orcltest ~]#
