Failed to create keys in the OLR, rc = 127, Message:
  /u01/11.2.0/grid/bin/clscfg.bin:error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory

Failed to create keys in the OLR at /u01/11.2.0/grid/crs/install/crsconfig_lib.pm line 7660.

说是找不到  libcap.so.1 这个包.

解决方法：

[root@node1 lib64]# cd /lib64 
[root@node1 lib64]# ls -lrt libcap 
libcap-ng.so.0      libcap-ng.so.0.0.0  libcap.so.2         libcap.so.2.16 
      
[root@node1 lib64]# ls -lrt libcap.so.2 
lrwxrwxrwx. 1 root root 14 12月 23 21:21 libcap.so.2 -> libcap.so.2.16 

[root@web1 node1]# ln -s libcap.so.2.16 libcap.so.1 

[root@node1 lib64]# ls -lrt libcap*
-rwxr-xr-x. 1 root root 18672 Jun 25  2011 libcap-ng.so.0.0.0
-rwxr-xr-x. 1 root root 19016 Dec  8  2011 libcap.so.2.16

lrwxrwxrwx  1 root root    14 Nov 24 13:17 libcap.so.1 -> libcap.so.2.16

继续执行脚本

[root@node1 lib64]# /u01/11.2.0/grid/root.sh
