ubuntu16源码安装python3.9及ssl

python新版本需要openssl 1.1.1，以支持ssl及pip下载。

1.安装openssl 1.1.1及测试

#从官网下载
# wget https://www.openssl.org/source/openssl-1.1.1n.tar.gz

#腾讯云提供的镜像
wget https://mirrors.cloud.tencent.com/openssl/source/openssl-1.1.1n.tar.gz

编译 openssl
tar -xvf openssl-1.1.1g.tar.gz
cd openssl-1.1.1g
./config shared --openssldir=/usr/local/openssl --prefix=/usr/local/openssl
make && make install

配置ssl

mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/lib/openssl /usr/lib/openssl.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
ldconfig -v 

查看版本：
/wk/tools/openssl$ openssl version
OpenSSL 1.1.1n  15 Mar 2022

验证ssl编译：

#include
#include

int main(){
        
        OpenSSL_add_all_algorithms();
        
        return 0;
}
gcc -o conftest -I/usr/local/openssl/include/ -L/usr/local/openssl/lib test_openssl.c -lssl -lcrypto -lcrypt -lpthread -ldl -lutil -lm
编译通过

2 python编译配置：

下载python版本
./configure --enable-optimizations --prefix=/opt/python3.9 --with-openssl=/usr/local/openssl --with-computed-gotos --enable-loadable-sqlite-extensions --enable-shared
make 
make install

编辑 /etc/ld.so.conf.d/python3.conf 添加一行
/opt/python3.9/lib/

ldconfig

import ssl正常：

$ /opt/python3.9/bin/python3
