如未设置则，export DISPLAY=*192.168.0.9*:0.0 (斜体字修改为自己的服务器的ip)

2   root用户执行 xhost +

3  切换到oracle用户安装即可

# Running X apps as root #

By default, and for security reasons, root will be unable to connect to a non-root user's X server. There are multiple ways of allowing root to do so, if it is necessary.

## The most secure methods ##

The most secure methods are simple. They include:

*  kdesu (included with KDE)

$ kdesu name-of-app

*  gksu (included with GNOME)

$ gksu name-of-app

*  bashrun (in community)

$ bashrun --su name-of-app

*  [sudo][] (must be installed and properly configured with `visudo`)

$ sudo name-of-app

*  [sux][] (wrapper around su which will transfer your X credentials)

$ sux root name-of-app

These are the preferred methods, because they automatically exit when the application exits, negating any security risks quite completely.

## Alternate methods ##

These methods will allow root to connect to a non-root user's X server, but present varying levels of security risks, especially if you run ssh. If you are behind a firewall, you may consider them to be safe enough for your requirements.

*  **Temporarily allow root access**

*  xhost

$ xhost +

will temporarily allow root, or *anyone* to connect your X server. Likewise,

$ xhost -

will disallow this function afterward.

Some users also use:

$ xhost + localhost

(Your X server must be configured to listen to TCP connections for `xhost + localhost` to work).

*  **Permanently allow root access**

**Method 1**: Add the line

`session optional pam_xauth.so`

to `/etc/pam.d/su` and `/etc/pam.d/su-l`. Then switch to your root user using 'su' or 'su -'.

**Method 2**: Globally in `/etc/profile`

Add the following to `/etc/profile`

export XAUTHORITY=/home/non-root-usersname/.Xauthority

This will permanently allow root to connect to a non-root user's X server.

Or, merely specify a particular app:

export XAUTHORITY=/home/usersname/.Xauthority kwrite

(to allow root to access kwrite, for instance.)
