在安装grid后，执行root.sh脚本时报错信息如下：

Installing Trace File Analyzer

通过查看发现只有包

[root@ryxr2 bin]# rpm -qa|grep libcap

libcap-ng-0.6.4-3.el6_0.1.x86_64

libcap-2.16-5.5.el6.x86_64

Yum安装compat-libcap1包即可（或安装所列出的所有rpm包）。

[root@ryxr1 grid]# yum install compat-libcap1

Complete!

再次执行root.sh前，需要删除配置信息（虽然我没有删除，但是依然成功）

./roothas.pl -deconfig -force

./root.sh
