python 3.8版本源码编译安装

安装脚本（centos环境）：

!#!/usr/bin/env bash

yum install -y wget

mkdir -p /ws/src && cd $_

# 安装相关依赖
yum install -y zlib-devel bzip2-devel ncurses-devel readline-devel openssl-devel openssl-static xz lzma xz-devel sqlite-devel gdbm-devel libffi-devel tk-devel gcc make

# 下载python源码包
wget https://www.python.org/ftp/python/3.8.10/Python-3.8.10.tgz
tar -xf Python-3.8.10.tgz && cd Python-3.8.10

# 编译安装python3
mkdir /usr/local/python3.8.10
./configure --prefix=/usr/local/python3.8.10 \
--with-ssl
# --enable-optimizations 可优化提升python10%左右的性能，编译安装时若报错：Could not import runpy module，原因是gcc版本过低，解决方法1、去除本参数；或2：升级gcc版本

# 如果生成Makefile过程中提示configure: WARNING: unrecognized options: --with-ssl，可编辑Modules/Setup文件，取消下述代码注释来解决问题
# _socket socketmodule.c
# SSL=/usr/local/ssl
# _ssl _ssl.c \
#         -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
#         -L$(SSL)/lib -lssl -lcrypto


make && make install

# 创建python pip软连接
ln -s /usr/local/python3.8.10/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3.8.10/bin/pip3 /usr/local/bin/pip3
