ORACLE 11g安装中出现xhost: unable to open display问题解决步骤

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

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 ResolutionDependencies Resolved=============================================================================================================================================================================================================================================================================== PackageArch Version Repository Size =============================================================================================================================================================================================================================================================================== Installing: xorg-x11-utilsx86_647.5-14.el6base101 k Installing for dependencies: libXxf86dga x86_641.1.4-2.1.el6 base 18 k libdmxx86_641.1.3-3.el6base 15 kTransaction Summary =============================================================================================================================================================================================================================================================================== Install3 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 kB00:00(2/3): libdmx-1.1.3-3.el6.x86_64.rpm | 15 kB00:00(3/3): xorg-x11-utils-7.5-14.el6.x86_64.rpm| 101 kB00:00------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 252 kB/s | 133 kB00:00Running 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 3/3Installed: xorg-x11-utils.x86_64 0:7.5-14.el6 Dependency Installed: libXxf86dga.x86_64 0:1.1.4-2.1.el6libdmx.x86_64 0:1.1.3-3.el6Complete! [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 ~]#
