基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境：4.安装Oracle RAC FAQ-4.4.无法图形化安装Grid Infrastructure

无法图形化安装:

[grid@linuxrac1 grid]$ ./runInstaller

DISPLAY not set. Please set the DISPLAY and try again.

Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:

– For csh:                      % setenv DISPLAY 192.168.1.128:0.0

– For sh, ksh and bash:         $ DISPLAY=192.168.1.128:0.0; export DISPLAY

Use the following command to see what shell is being used:

echo $SHELL

Use the following command to view the current DISPLAY environment variable setting:

echo $DISPLAY

– Make sure that client users are authorized to connect to the X Server.

To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command:

% xhost +

To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as ‘xclock’:

% <full path to xclock.. see below>

If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further

assistance.

Typical path for xclock: /usr/X11R6/bin/xclock

2.通过Xmanager实现图形化安装

1）第一种：通过Xmanager passive实现：

a).首先在本机安装Xmanager，我这里安装的是Xmanager4。安装方法跟普通软件一样，除了要输入SN号那里输入下（101210-450789-147200），其他的一直点下一步即可。

b).安装完后，打开xmanager里面的passive。

c).远程登录到“需要使用图形界面软件的终端”，执行如下命令

[grid@ linuxrac1 ~]$ export DISPLAY=10.10.97.168:0.0    #设置输出到哪个机器，就填写该机器IP

[grid @ linuxrac1~]$ xhost +

access control disabled, clients can connectfrom any host

注意：执行xhost +后，会告诉你“访问控制已关闭，可从任何地方的客户端连接”

2）Xbrowser 实现

Xbrowser 使用协议通过图形化桌面远程连接到linux,xftp使用SSH协议传送文件到linux服务器，xshell通过SSH终端协议连接到linux进行字符界面管理，Xstart通过xstart sample 图形化界面连接到linux。

Xbrower服务配置：

a).编辑设置文件: vi /etc/gdm/custom.conf ，修改为如下所示：

[root@ linuxrac1 ~]$ vi /etc/gdm/custom.conf

[security]

AllowRemoteRoot=true #允许root登陆

[xdmcp]

Enable=true #开启xdcmp服务

Port=177  #指定服务端口

b).调整开机启动级别：vi /etc/inittab ，将默认启动级别改为5，即默认从图像化界面启动，若已经是5，则不需要修改。

[root@ linuxrac1 ~]$ vi /etc/inittab

id:5 initdefault;

c).然后，重启服务器：reboot

[root@ linuxrac1 ~]$ reboot

d).重启后，验证服务是否开启

[root@ linuxrac1 ~]$lsof-i:177

e).使用Xbrower登陆
