It seems the softlink of the libstdc++.so.6has been changed and is pointing to libstdc++.so.6.0.13(64-bit?). I just changed the softlink by issuing the following command (in /usr/libfolder):
似乎软链接libstdc++.so.6已更改并指向libstdc++.so.6.0.13（64位？）。我只是通过发出以下命令（在/usr/lib文件夹中）更改了软链接：
rm -f libstdc++.so.6
ln -s ./libstdc++.so.6.0.8 ./libstdc++.so.6

yum reinstall $(rpm -qa)
The above command will resolve all the issue in centos.
以上命令将解决centos中的所有问题。
