CentOS|CentOS 6.9 升级 glibc 2.12 到 2.17（qbit） CentOS6.9升级glibc2.12到2.17（qbi

前言

当前日期是 2022.7.6，CentOS 6 停止维护更新日期是 2020.11.30，CentOS 6 已停止维护近两年
由于种种原因，qbit 需要在 CentOS 6.9 上通过 Miniconda 安装 Python 3.8，发现 glibc 版本太旧装不上，于是试验升级了glibc
【CentOS|CentOS 6.9 升级 glibc 2.12 到 2.17（qbit）】初始环境

CentOS 6.9 x86_64 glibc 2.12
