是因为服务器系统为64位，但是交叉编译工具链是32位。

重装glibc

yum  install glibc.i686

 

遇到报错

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, Aug 7 2019, 00:51:29)
[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:
http://yum.baseurl.org/wiki/Faq

查看依赖关系 ldd /usr/lib64/python2.7/site-packages/pycurl.so 

发现异常依赖路径libcurl.so.4 => /usr/local/lib/libcurl.so.4 (0x00007f25fbb43000)

然后查看libcurl 安装信息 ldconfig -p|grep curl

    libcurl.so.4 (libc6,x86-64) => /usr/local/lib/libcurl.so.4
    libcurl.so.4 (libc6,x86-64) => /lib64/libcurl.so.4

发现有两个libcurl

最简单方式 去掉看起来路径不正常那个/usr/local/lib/libcurl.so.4

继续安装glibc 

yum  install glibc.i686

等待结束后如果报error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

继续安装libstdc++

yum install libstdc++.so.6
