centos7编译安装python3

1.安装依赖

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel

2.下载软件包

wget https://www.python.org/ftp/python/3.9.7/Python-3.9.7.tar.xz

下载列表：https://www.python.org/ftp/python/

3.编译安装

wget http://www.openssl.org/source/openssl-1.1.1.tar.gz
tar xf openssl-1.1.1.tar.gz
cd openssl-1.1.1/
./config --prefix=/usr/local/openssl shared zlib
make && make install


tar -xf Python-3.9.7.tar
cd Python-3.9.7
./configure --prefix=/usr/local/python3.9  --with-ssl=/usr/local/openssl 
make && make install

 

如果使用系统默认版本，默认系统OpenSSL版本不适配，需要升级

yum install -y epel-release.noarch 
yum install -y openssl11 openssl11-devel

cd Python-3.10.xxx #进入目录后替换编译命令
# 替换openssl 为openssl11
sed -i 's/PKG_CONFIG openssl /PKG_CONFIG openssl11 /g' configure　

4.配置PATH及验证

vim ~/.bash_profile 
PATH=/usr/local/python3.9/bin:$PATH:$HOME/bin
. ~/.bash_profile 

env python3
