There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
/usr/lib64/python2.7/site-packages/rpm/_rpm.so: undefined symbol: rpmpkgVerifySigs
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:
2.7.5 (default, Aug 4 2017, 00:39:18)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
在执行了某个安装脚本后，centos出现了rpmpkgverifySigs问题，rpmpkgverifySigs 为对/usr/lib64/python2.7/site-packages/rpm/_rpm.so的调用
通过查询python版本发现rpm-python-4.11.3-25.el7.x86_64
[root@izuf62ib33y8vc9nmb3w1zz bin]# rpm -qa|grep python
python-devel-2.7.5-58.el7.x86_64
python-urlgrabber-3.10-8.el7.noarch
python-2.7.5-58.el7.x86_64
python-pycurl-7.19.0-19.el7.x86_64
python-libs-2.7.5-58.el7.x86_64
python-iniparse-0.4-9.el7.noarch
rpm-python-4.11.3-25.el7.x86_64
通过rpm -Uvh * --nodeps安装http://mirrors.163.com/centos/7/os/x86_64/Packages/下载的
python-2.7.5-88.el7.x86_64.rpm python-pycurl-7.19.0-19.el7.x86_64.rpm yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

python-iniparse-0.4-9.el7.noarch.rpm rpm-python-4.11.3-43.el7.x86_64.rpm
python-libs-2.7.5-88.el7.x86_64.rpm yum-3.4.3-167.el7.centos.noarch.rpm几个软件后问题任然存在，最后网上查询发现缺少部分rpm包
便全部卸载重装后解决
