``/usr/bin/python3`` as the interpreter path.

To use shell commands in your Python scripts, look at the :mod:`subprocess` module.

Custom OpenSSL
|
||||
==============
|
||||
|
||||
1. To use your vendor's OpenSSL configuration and system trust store, locate
|
||||
the directory with ``openssl.cnf`` file or symlink in ``/etc``. On most
|
||||
distribution the file is either in ``/etc/ssl`` or ``/etc/pki/tls``. The
|
||||
directory should also contain a ``cert.pem`` file and/or a ``certs``
|
||||
directory.
|
||||
|
||||
.. code-block:: shell-session
|
||||
|
||||
$ find /etc/ -name openssl.cnf -printf "%h\n"
|
||||
/etc/ssl
|
||||
|
||||
2. Download, build, and install OpenSSL. Make sure you use ``install_sw`` and
|
||||
not ``install``. The ``install_sw`` target does not override
|
||||
``openssl.cnf``.
|
||||
|
||||
.. code-block:: shell-session
|
||||
|
||||
$ curl -O https://www.openssl.org/source/openssl-VERSION.tar.gz
|
||||
$ tar xzf openssl-VERSION
|
||||
$ pushd openssl-VERSION
|
||||
$ ./config \
|
||||
--prefix=/usr/local/custom-openssl \
|
||||
--openssldir=/etc/ssl
|
||||
$ make -j1 depend
|
||||
$ make -j8
|
||||
$ make install_sw
|
||||
$ popd
|
||||
|
||||
3. Build Python with custom OpenSSL
|
||||
|
||||
.. code-block:: shell-session
|
||||
|
||||
$ pushd python-3.x.x
|
||||
$ ./configure -C \
|
||||
--with-openssl=/usr/local/custom-openssl \
|
||||
--with-openssl-rpath=auto \
|
||||
--prefix=/usr/local/python-3.x.x
|
||||
$ make -j8
|
||||
$ make altinstall
|
||||
|
||||
.. note::
|
||||
|
||||
Patch releases of OpenSSL have a backwards compatible ABI. You don't need
|
||||
to recompile Python to update OpenSSL. It's sufficient to replace the
|
||||
custom OpenSSL installation with a newer version.
