强制卸载 openssl ，将致使 yum 没法使用

问题描述

使用以下方式强制性的卸载了 openssl 。

rpm -e --nodeps openssl

结果致使 yum 没法使用，异常信息以下所示。

[root@Development ~]# yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   libssl.so.10: 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, Feb 22 2013, 00:00:18) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

解决方法

找到 openssl 的 rpm 包，好比 openssl-1.0.0-27.el6.x86_64.rpm ，安装它。

[root@Development tools]# rpm -ipv openssl-1.0.0-27.el6.x86_64.rpm 
warning: openssl-1.0.0-27.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing packages for installation...
openssl-1.0.0-27.el6

此时，openssl 从新装上了，yum 也能正常使用了。
