CentOS 6.9 升级 glibc 2.12 到 2.17（qbit）

qbit - 2022-07-13 15:03:54

---

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

初始环境

CentOS 6.9 x86_64
glibc 2.12

升级步骤

直接安装 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.

查看当前 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 上的脚本升级 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

X64=x86_64
I386=i386
I636=i686

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_2=$GLIBC-common
P_3=$GLIBC-devel
P_4=$GLIBC-headers
P_5=$GLIBC-static
P_6=$GLIBC-utils
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

再次检查当前 glibc 版本（不用重启）

$ ldd --version
ldd (GNU libc) 2.17

正常安装 Miniconda3

$ sh Miniconda3-py38_4.12.0-Linux-x86_64.sh

后记

安装 Miniconda 后发现 pip3 不能安装包，一直卡住不动

$ pip3 install pipx -vvv

排查后发现是 Miniconda 的 openssl 有问题

$ which openssl
~/miniconda3/bin/openssl
$ openssl version
OpenSSL 1.1.1n  15 Mar 2022
$ openssl s_client mirrors.aliyun.com:443
卡住...

解决方式一，用 http 仓库代替 https 仓库

pip3 config set global.index-url http://mirrors.aliyun.com/pypi/simple/
pip3 config set global.trusted-host mirrors.aliyun.com
