在xmanager下配置远程Oracle linux 6.5连接，遇到了一些问题。

1.没有/etc/X11/xdm/xdm-config文件

这个是因为缺少 xorg-x11-xdm包，用yum进行安装

[root@11grac1 Server]# yum install xorg-x11-xdm
Loaded plugins: rhnplugin, security
This system is not registered with ULN.
You can use up2date --register to register.

Complete!

配置步骤如下：

1.vi /etc/inittab

id:5:initdefault:

2.vi /etc/gdm/custom.conf

[security]
AllowRoot=true
AllowRemoteRoot=true
[xdmcp]
Enable=true
Port=177

3.vi /etc/X11/xdm/xdm-config

!DisplayManager.requestPort:    0 

4.vi /etc/X11/xdm/Xaccess

去掉前面的#

#*                                       #any host can get a login window

#*               CHOOSER BROADCAST       #any indirect host can get a chooser

5.关闭防火墙

6.DISPLAY=192.168.1.222:3

7.使用Xmanager连接数据库，可以正常使用。
