-rwxr-xr-x 1 root root 19016 Nov 5 2011 libcap.so.2.11
4、整体解决办法：
①缺少系统补丁包“libcap"补丁包
# rpm -ivh|grep libcap
libcap2-32bit-2.11-2.17.1
libcap2-2.11-2.17.1
②缺少链接文件“libcap.so.1”
查找所缺链接文件的位置：
# find / -name libcap*
/lib/libcap.so.2
/lib/libcap.so.2.11
/lib64/libcap.so.2
/lib64/libcap.so.2.11
/lib64/libcap.so.1.10
创建链接文件：
# cd /lib64
# ln -s libcap.so.1.10 libcap.so.1
#ls -al libcap*
lrwxrwxrwx 1 root root 14 Aug 1 17:22 libcap.so.1 -> libcap.so.1.10
-rwxr-xr-x 1 root root 14792 Feb 21 2009 libcap.so.1.10
