关于glibc:CentOS-69-升级-glibc-212-到-217qbit

以后日期是 2022.7.6，CentOS 6 进行保护更新日期是 2020.11.30，CentOS 6 已进行保护近两年
因为种种原因，qbit 须要在 CentOS 6.9 上通过 Miniconda 装置 Python 3.8，发现 glibc 版本太旧装不上，于是试验降级了 glibc
初始环境
```
CentOS 6.9 x86_64
glibc 2.12
```

间接装置 MiniConda3 报错

$ sh Miniconda3-py38_4.12.0-Linux-x86_64.sh 
WARNING:
  The installer is not compatible with the version of the Linux distribution
  installed on your system. The version of GLIBC is no longer supported.
  Found version 2.12, which is less than 2.17
Aborting installation.

查看以后 glibc 版本

$ ldd --version

切换软件仓库（centos-vault 源）

 curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.repo

生成缓存
```
yum makecache
```

用 github 上的脚本降级 glibc，脚本内容如下

#!/bin/bash

# update glibc to 2.17 for CentOS 6

GLIBC=glibc
OS=el6
SERVER=https://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6
VERSION=2.17-55
FULL_VERSION=$GLIBC-$VERSION.fc20
X64=x86_64

REPO_64=epel-6-$X64

SERVER_32=$SERVER/$REPO_32/$FULL_VERSION
RPM_32=$VERSION.$OS.$I636.rpm
SERVER_64=$SERVER/$REPO_64/$FULL_VERSION

P_7=nscd

# Required as dependency of glibc-utils
sudo yum install --assumeyes gd

# 64-bit
sudo rpm -Uvh --force $SERVER_64/$P_1-$RPM_64 $SERVER_64/$P_2-$RPM_64 $SERVER_64/$P_3-$RPM_64 $SERVER_64/$P_4-$RPM_64 $SERVER_64/$P_5-$RPM_64 $SERVER_64/$P_6-$RPM_64 $SERVER_64/$P_7-$RPM_64
# Print out versions
strings /lib64/libc.so.6 | grep GLIBC

再次查看以后 glibc 版本（不必重启）

$ ldd --version
