glibc下载安装
http://ftp.gnu.org/gnu/glibc/
https://blog.csdn.net/cpplang/article/details/8462768
libc.so.6指向不是2.14或需要的版本的时候，需要手动将需要的版本拷贝到/lib64目录下，删除软链接（慎操作！！会导致机器起不来，命令用不了！如出现，及时#ldconfig命令救场）再恢复软链接。
#LD_PRELOAD=/lib64/libc-2.14.so ln -s/lib64/libc-2.14.so /lib64/libc.so.6
strings /lib64/libc.so.6 | grep GLIBC 出现所需版本即安装成功。
