部署Oracle RAC环境安装grid软件在到最后两个节点执行脚本时，第二个节点执行root.sh报错提示如下：

Failed to create keys in the OLR, rc = 127, Message:
  /app/grid/11.2.0/bin/clscfg.bin: error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory

问题分析：

说是找不到  libcap.so.1 这个包，创建链接文件进行处理

问题处理：

创建链接文件

$ cd /lib64
$ ls -ltr libcap*
-rwxr-xr-x. 1 root root 18672 Nov  5  2010 libcap-ng.so.0.0.0
-rwxr-xr-x  1 root root 19016 Aug 23  2011 libcap.so.2.16

lrwxrwxrwx  1 root root    14 Aug 18 18:19 libcap.so.1 -> libcap.so.2.16

继续在第二个节点执行root.sh，执行成功

$ sudo sh /app/grid/11.2.0/root.sh
