在讨论这个问题之前，我使用的是 RedHat 6.5，由于环境限制，无法访问互联网来下载 yum 更新。在这种情况下，我只有 CD ROM（RHEL 6.5）可以使用。更新映像后，我们使用互联网服务器来获取更新，但在此之前，服务器需要能够独立运行。
在图像上我需要使用 ldapsearch，所以我执行了 yum whatprovides */ldapsearch 来确定要安装哪个包。
我收到了：
openldap-clients-2.4.23-32.el6_4.1.x86_64 : LDAP client utilities
Repo : cdrom
Matched from:
Filename : /usr/bin/ldapsearch
当我去安装这个包时：
[root@test1 yum.repos.d]# yum install openldap-clients-2.4.23-32.el6_4.1.x86_64
Loaded plugins: product-id, security, subscription-manager

看起来我还没有安装适合我的版本的正确软件包：
[root@test1 yum.repos.d]# rpm -qa | grep glibc
glibc-common-2.12-1.132.el6_5.2.x86_64
glibc-2.12-1.132.el6_5.2.x86_64
显然，如果我尝试删除 glibc 并从提供较新版本的 CD-ROM 重新安装，我会收到一大堆错误，因为 glibc 无法被完全删除...

我该怎么做才能删除这个 _5.2 版本的 glibc 并用光盘上可用的较新版本替换它？
