问题原因
libstdc++.so.6系列报错是由于当前动态库版本较低不满足软件的先决条件，从错误来看至少需要22以上的版本，用高版本（libstdc++.so.6.0.25或者更高）替换后从新创建软件连接即可。
libm.so.6、libc.so.6错误由于glibc版本较低导致，从错误来看至少需要2.28的版本
解决办法
问题1
将libstdc++.so.6.0.25放入/usr/lib64/libstdc++.so.6.0.25
删除原有的libstdc++.so.6
建立新的软件链接
ln -vs libstdc++.so.6.0.25 libstdc++.so.6
问题2
编译安装glibc-2.28
下载地址：http://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz
centos7.9 make和gcc版本较低，无法通过先决条件需要升级
yum install centos-release-scl -y
yum install devtoolset-7 -y
scl enable devtoolset-7 bash
激活Developer Toolset 7软件集，并创建Shell
source scl_source enable devtoolset-7
开始编译安装glibc
cd glibc-2.28 && mkdir -p build
cd build/
make -j all
make install
解决完上述问题后即可正常安装MySQL8.0.34！
