ubuntu16安装python3.12

1）新python依赖openssl，所以先安装openssl

在https://www.openssl-library.org/source 下载最新稳定版3.5.3(https://github.com/openssl/openssl/releases/download/openssl-3.5.3/openssl-3.5.3.tar.gz)

./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl --shared zlib
make
sudo make install

安装后配置系统库

cd /etc/ld.so.conf.d/
vim openssl-3.1.4.conf
填入目标库:
/usr/local/openssl/lib64
或者
sudo echo "/usr/local/openssl/lib64" >> /etc/ld.so.conf查看
sudo ldconfig -v创建新连接
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/bin/openssl /usr/local/bin/openssl
ln -s /usr/local/openssl/lib64/libcrypto.so.3 /lib/libcrypto.so.3
ln -s /usr/local/openssl/lib64/libcrypto.so.3 /lib/libcrypto.so.6
ln -s /usr/local/openssl/lib64/libssl.so.3  /usr/lib64/libssl.so.3
ln -s /usr/local/openssl/lib64/libcrypto.so.3  /usr/lib64/libcrypto.so.3
ln -s /usr/local/openssl/lib64/libssl.so  /usr/lib64/libssl.so
ln -s /usr/local/openssl/lib64/libcrypto.so  /usr/lib64/libcrypto.so验证
openssl version -a

2）编译python老是提示缺openssl模块

./python -E -c 'import sys ; from sysconfig import get_platform ; print("%s-%d.%d" % (get_platform(), *sys.version_info[:2]))' >platform
The necessary bits to build these optional modules were not found:
_bz2                  _lzma                 _ssl             _tkinter           
_uuid                                      

安装配置如下解决:

wget https://www.python.org/ftp/python/3.12.0/Python-3.12.0.tgz
tar -xf Python-3.12.0.tgz
cd Python-3.12.0./configure --enable-optimizations --with-openssl=/usr/local/openssl --with-openssl-rpath=/usr/local/openssl/lib64 LDFLAGS=-L/usr/local/openssl/lib64make -j $(nproc)
sudo make install
