Python3 默认不支持OpenSSL 1.1.1+以下版本，如果OpenSSL版本过低会提示以下报错ImportError: urllib3 v2 only supports OpenSSL 1.1.1+, currently the ‘ssl‘ module is compiled with ‘O 本次离线安装同时解决Python3依赖OpenSSL版本问题

编译安装OpenSSL


wget https://www.openssl.org/source/openssl-1.1.1a.tar.gz
tar -xzvf openssl-1.1.1a.tar.gz
cd openssl-1.1.1a
./config --prefix=/usr/local/openssl-1.1.1a
make
make install


添加ld.so.conf

echo "/usr/local/openssl-1.1.1a/lib/" >> /etc/ld.so.conf
ldconfig


不需要替换OpenSSL，直接在Python包中引用即可

[root@kafka-manager bin]# cd /usr/local/openssl-1.1.1a/bin
[root@kafka-manager bin]# ./openssl version
OpenSSL 1.1.1a  20 Nov 2018 (Library: OpenSSL 1.1.1k  FIPS 25 Mar 2021)


编译Python


编译Python依赖zlib-devel，需要自行提前本地yum安装

yum install zlib-devel


下载并编译Python3

wget https://www.python.org/ftp/python/3.8.9/Python-3.8.9.tgz
tar xf Python-3.8.9.tgz
cd Python-3.8.9
./configure --prefix=/opt/python3.8  --with-openssl=/usr/local/openssl-1.1.1a
make && make install


验证服务


验证Python3是否正常

[root@kafka-manager python3.8]# /opt/python3.8/bin/python3 -V
Python 3.8.9


验证Pip3是否正常

[root@kafka-manager python3.8]# /opt/python3.8/bin/pip3 -V
pip 20.2.3 from /opt/python3.8/lib/python3.8/site-packages/pip (python 3.8)


离线安装requests


我们找台有外网的机器，提前下载依赖包

/opt/python3.8/bin/pip3 download -d packages requests


在当前目录会生成package目录

[root@kafka-manager python3.8]# cd packages/
[root@kafka-manager packages]# ls
certifi-2025.1.31-py3-none-any.whl          idna-3.10-py3-none-any.whl            urllib3-1.26.20-py2.py3-none-any.whl
charset_normalizer-2.0.12-py3-none-any.whl  requests-2.27.1-py2.py3-none-any.whl


导入package包，进入package目录，导入离线包

[root@kafka-manager packages]# /opt/python3.8/bin/pip3 install *.whl
Processing ./certifi-2025.1.31-py3-none-any.whl

查看现有包

[root@kafka-manager packages]# /opt/python3.8/bin/pip3 list
