背景：

python版本：3.9.15

OS：openEuler 20.03 SP1

软件栈：系统自带gcc、g++、gfortran

依赖库：yum install gcc libffi* openssl-devel zlib* bzip2 gcc-c++ gcc-gfortran readline-devel

报错现象：

cd /home

wget https://www.python.org/ftp/python/3.9.15/Python-3.9.15.tar.xz --no-check-certificate

tar xf Python-3.9.15.tar.xz

cd Python-3.9.15

./configure --prefix=/home/Python-3.9.15_install --enable-shared --enable-optimizations --with-ssl-default-suites=openssl

make -j

解决方案：

建议使用libressl替代openssl，libressl 是 openssl 更安全版本分支。

cd /home

wget https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-2.7.4.tar.gz  --no-check-certificate

tar xf libressl-2.7.4.tar.gz

cd libressl-2.7.4

./configure --prefix=/home/libressl-2.7.4_install

make -j

make install

export PATH=/home/libressl-2.7.4_install/bin:$PATH

export LD_LIBRARY_PATH=/home/libressl-2.7.4_install/lib:$LD_LIBRARY_PATH

export INCLUDE=/home/libressl-2.7.4_install/include:$INCLUDE

安装完成libressl后，重新安装python3

cd /home

rm -rf /home/Python-3.9.15

tar xf Python-3.9.15.tar.xz

cd Python-3.9.15

sed -i "214,217s/^#//g" Modules/Setup

sed -i "214s%/usr/local/ssl%/home/libressl-2.7.4_install%g" Modules/Setup

./configure --prefix=/home/Python-3.9.15_install --enable-shared --enable-optimizations

make -j

make install

export PATH=/home/Python-3.9.15_install/bin:$PATH

export LD_LIBRARY_PATH=/home/Python-3.9.15_install/lib:$LD_LIBRARY_PATH

此时已安装完成python3，在服务器中输入python3，再输入import ssl，无报错信息，即安装ssl模块完成
