ubuntu安装python3.8-ssl

1. 下载 openssl
   https://www.openssl.org/source/old/1.1.1/openssl-1.1.1d.tar.gz
   注意：python3.8 最好下载高版本 openssl
2. 编译 openssl

tar zxvf openssl-1.1.1d.tar.gz openssl-1.1.1d
cd openssl-1.1.1d
sudo ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl
sudo make
sudo make test
sudo make install

3. 将编译后 openssl 动态库，加入搜索路径

sudo mkdir lib64
sudo ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/lib64/libssl.so.1.1
sudo ln -s /usr/local/openssl/lib/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
sudo su
echo "/usr/lib64" >> /etc/ld.so.conf.d/lib64.conf
// 查看是否成功
ldconfig -v

4. 下载 python3.8.5
   https://www.python.org/downloads/source/
5. 解压 python

tar zxvf python3.8.5.tar.gz python3.8.5
cd python3.8.5
sudo apt-get install libffi-dev

6. 修改配置
   vi modules/Setup
   放开如下注释：

SSL=/usr/local/openssl
\_ssl \_ssl.c \
 -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
 -L$(SSL)/lib -lssl -lcrypto

7. 编译 python

sudo ./configure --prefix=/usr/local/python
sudo make
sudo make install

8. 加入动态管理 python

sudo update-alternatives --install /usr/bin/python python /usr/local/python/python3.8.5/bin/python3.8 3
sudo update-alternatives --config python
