1.背景: 卸载openldap相关的所有rpm包后，出现libldap-2.4.so.2: cannot open shared object file: No such file or directory
[root@sht-sgmhadoopcm-01 ~]# rpm -qa|grep openldap

[root@sht-sgmhadoopcm-01 ~]# rpm -e openldap-* –nodeps

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
libldap-2.4.so.2: cannot open shared object file: No such file or directory
Please install a package which provides this module, or
verify that the module is installed correctly.
It’s possible that the above module doesn’t match the
current version of Python, which is:
2.6.6 (r266:84292, Nov 22 2013, 12:16:22)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]
If you cannot solve this problem yourself, please go to
the yum faq at:

2.解决办法:下载openldap-2.4.23-32.el6_4.1.x86_64.rpm,校验MD5,再强制安装
[root@sht-sgmhadoopcm-01 ~]# wget http://ftp.pbone.net/mirror/ftp.scientificlinux.org/linux/scientific/6.4/x86_64/updates/fastbugs/openldap-2.4.23-32.el6_4.1.x86_64.rpm
[root@sht-sgmhadoopcm-01 ~]# rpm -v –checksig ./openldap-2.4.23-32.el6_4.1.x86_64.rpm
