ORACLE11g 安装中xhost: unable to open display 问题解决纪实

1，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"

 

 

2，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.          Underlying X server release 11704000, The X.Org Foundation              Tue Mar 14 03:23:26 2017           vncext:      VNC extension running!           vncext:      Listening for VNC connections on all interface(s), port 5901           vncext:      created VNC server for screen 0          GNOME_KEYRING_SOCKET=/tmp/keyring-jRupIx/socket          SSH_AUTH_SOCK=/tmp/keyring-jRupIx/socket.ssh          GNOME_KEYRING_PID=7358          Cleaned 21 files 7 still live          Failed to play sound: Not available            (polkit-gnome-authentication-agent-1:7380): GLib-GObject-WARNING **: cannot register existing type `_PolkitError'            (polkit-gnome-authentication-agent-1:7380): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed            ** (gnome-user-share:7381): WARNING **: gnome-user-share cannot be started as root for security reasons.          Initializing nautilus-gdu extension            ** (gnome-panel:7372): WARNING **: panel-applet-frame.c:1288: failed to load applet OAFIID:GnoteApplet:          (null)            ** (gnome-panel:7372): WARNING **: panel-applet-frame.c:1288: failed to load applet OAFIID:GNOME_FastUserSwitchApplet:          (null)

 

3，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

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 ~]#
