[已解决] 我发现内存芯片导致了问题。我改了，现在系统工作正常了！
我正在使用RHEL6.0，遇到gdb、yum、rpm不再工作的问题。也许包依赖性导致了问题。

# uname -a

运行gdb要么返回错误，要么随机崩溃：
#gdb
gdb: symbol lookup error: /usr/lib/libpython2.6.so.1.0: undefined symbol: yCodec_Lookup
yum也失败：
#yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
/usr/lib/python2.6/site-packages/rpm/_rpmmodule.so: undefined symbol: headerKsEntry
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, Jan 22 2014, 09:37:14)
[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:
http://yum.baseurl.org/wiki/Faq

我曾经rpm检查过：

答案1
看起来你的 rpmdb 已损坏，rpm -V python说package python is not installed，但yum甚至告诉你你有什么 python 版本。
所以首先尝试重建你的 rpmdb：
mv /var/lib/rpm /var/lib/rpm.bak
mkdir /var/lib/rpm
cp /var/lib/rpm.bak/packages /var/lib/rpm
rpm --rebuilddb
restorecon -r /var/lib/rpm
之后重新运行rpm -V python yum并运行yum check。
如果您的 rpmdb 无法重建，请删除/var/lib/rpm，移回/var/lib/rpm.bak原处并运行restorecon -vr /var/lib/rpm（如果得到一些输出），请运行，rm -f /var/lib/rpm/__*然后重新运行rpm --rebuilddb
如果这也无法修复它，请从 redhat 存储库手动下载并安装，rpm-python然后重试pythonrpm -i rpm-python pythonrpm --rebuilddb
