centos7 arm服务器编译安装python 3.8

前言

CentOS (Community Enterprise Operating System) 是一种基于 Red Hat Enterprise Linux (RHEL) 进行源代码再编译并免费提供给用户的 Linux 操作系统。

CentOS 7 采用了最新的技术和软件包，并提供了强大的功能和稳定性。它适用于各种服务器和工作站应用场景，并具有广泛的支持和用户社区，这里我详细讲解下Python 3.8编译安装，其他linux环境也可借鉴。

软件准备

1、Python的安装包

可以在Python官网下载，这里提供一个3.8版本的Python包下载地址：Python-3.8.18.tgz

2、centos7系统

系统下载地址：centos-altarch-7.9.2009-isos-aarch64安装包下载_开源镜像站-阿里云 (aliyun.com)

推荐Minimal-2009版本的

添加系统源

vim /etc/yum.repos.d/CentOS-Base.repo

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra

3、系统依赖包

通过yum命令将缺少的包安装上，这样运行编译后的Python的时候报缺少模块错误

yum install zlib* bzip2* libffi* sqlite* gdbm* uuid lzma* tk* libssl* openssl* xz*

开始编译

1、解压tgz包或者tar.gz包

tar -xvzf <源码包>

2、开始构建

./configure --prefix=/usr/local/python3.8 --enable-optimizations

如构建后，使用python3过程中出现错误：

“ImportError: urllib3 v2.0 only supports OpenSSL 1.1.1+”：

查看这篇文章编译安装openssl：【centos7 arm服务器编译安装openssl 1.1.1版本】

如何构建命令改成这样

./configure --prefix=/usr/local/python3.8 --with-openssl=/usr/local/openssl-1.1.1 --enable-optimizations

3、编译

make && make install

4、编译完成后，配置环境：

echo 'export PATH=/usr/local/python3.8/bin:$PATH' >> ~/.bashrc

source ~/.bashrc

ln -sf /usr/local/python3.8/bin/python3.8 /usr/bin/python3

ln -sf /usr/local/python3.8/bin/pip3.8 /usr/bin/pip3

输入python3 -V结果为python3.8就代表编译完成。
