yum
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/pycurl.so: undefined symbol: CRYPTO_num_locks
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, Apr 2 2020, 13:16:51)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
If you cannot solve this problem yourself, please go to
the yum faq at:

解决方法：
使用 ldconfig -p | grep curl 查看libcurl.so的链接情况
[user01@node3 ~]$ ldconfig -p | grep curl
libcurl.so.4 (libc6,x86-64) => /lib64/libcurl.so.4
libcurl.so (libc6,x86-64) => /lib64/libcurl.so
分别查看libcurl.so.4链接的文件
ls -l /lib64/libcurl.so.4
lrwxrwxrwx. 1 root root 16 May 21 2020 /lib64/libcurl.so.4 -> libcurl.so.4.3.0
ls -l /lib64/libcurl.so
lrwxrwxrwx. 1 root root 16 Sep 25 16:10 /lib64/libcurl.so -> libcurl.so.4.3.0
删除其中高版本的
删除之后使用命令ldconfig重新加载
加载完成后使用ldconfig -p | grep curl查看libcurl.so的链接情况，保证只有一个libcurl.so.4
