oracle 安装出现 must be configured to display at least 256 colors 问题

mahan

安装oracle11g时，运行xmanager
export DISPLAY=192.168.133.xxx:0.0
./runInstall.sh
出现如下提示：
Checking Temp space: must be greater than 120 MB. Actual 29477 MB Passed
Checking swap space: must be greater than 150 MB. Actual 511 MB Passed
Checking monitor: must be configured to display at least 256 colors>>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<
Some requirement checks failed. You must fulfill these requirements before


解决方案：
1. 安装xdpyinfo
yum install -y xdpyinfo
2. root下执行
xhost +
3. oracle下执行
export DISPLAY=192.168.133.xxx:0.0

再次运行安装脚本就出现图像界面。
