os:centos6.5 grid:11.2.0.3

在grid安装中运行第二个节点的root.sh时，报错如下：

root@vmac1 ~]# /u01/app/11.2.0/grid/root.sh

经过google、百度，查找到了解决方法：

1.首先确保操作系统的libcap包已经安装（如果是x86_64bit，那么64bit和32bit都已经安装）。

若未安装请使用如下命令：

[root@vmac1 ~]# yum install compat-libcap1

由于我的操作系统的Libcap包的x86-64都已经安装，再用yum安装32位的即可。

2.之后执行如下操作：

[root@vmac1 /]# cd lib64
[root@vmac1 lib64]# ls -al libcap.so*
lrwxrwxrwx. 1 root root    14 Jul  6 15:35 libcap.so.2 -> libcap.so.2.16
-rwxr-xr-x. 1 root root 18920 Feb 26  2010 libcap.so.2.16
[root@vmac1 lib64]#ln -s libcap.so.2.16 libcap.so.1
[root@vmac1 lib64]# ls -al libcap.so*
lrwxrwxrwx. 1 root root    14 Jul  7 04:33 libcap.so.1 -> libcap.so.2.16
lrwxrwxrwx. 1 root root    14 Jul  6 15:35 libcap.so.2 -> libcap.so.2.16
-rwxr-xr-x. 1 root root 18920 Feb 26  2010 libcap.so.2.16
