python3.10.5安装时openssl安装失败的问题

初始问题：编译安装python后执行pip list 报错

[root@VM-0-6-centos Python-3.10.5]# pip3 list
Package    Version
---------- -------
pip        22.0.4
setuptools 58.1.0
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping
[root@VM-0-6-centos Python-3.10.5]# 

解决办法：
参考链接更新openssl版本：https://blog.csdn.net/tfstone/article/details/109223506，更新版本至3.0.3

更新后，问题依旧存在，检查编译过程，发现编译失败的问题

Python requires a OpenSSL 1.1.1 or newer

根据报错信息，需要 1.1.1版本以上的openssl，显然条件已经满足，那么应该是旧环境未清理干净所致，严格按照流程重新安装编译

最重要是第10步，指定编译依赖库为新版本openssl相关依赖，这里的路径需要根据安装目录灵活配置，例如：

 export LD_LIBRARY_PATH=/usr/local/openssl/lib64:$LD_LIBRARY_PATH
