Compiling portable Python

1On the low-version system machine, compile the PYTHON:CD Python-2.7.15/Modules Vim setup.dist Modify the following code:###########Sed-i's/#SSL =\/usr\/local\/ssl/ssl=\/usr\/local\/ansible_python\/openssl_for_python/g'modules/setup.distsed-I.'s/#_ssl _ssl.c/_ssl _ssl.c/g'modules/setup.distsed-I.'s/#\t-duse_ssl/\t-duse_ssl/g'modules/setup.distsed-I.'s/#\t-l$ (SSL)/\t-l$ (SSL)/g'modules/setup.distsed-I.'s/#_md5 md5module.c md5.c/_md5 md5module.c md5.c/g'modules/setup.distsed-I.'s/#zlib zlibmodule.c/zlib zlibmodule.c/g'modules/setup.distsed-I.'s/#binascii binascii.c/binascii binascii.c/g'modules/setup.distsed-I.'s/#_sha1 sha1module.c/_sha1 sha1module.c/g'modules/setup.distsed-I.'s/#_sha256 sha256module.c/_sha256 sha256module.c/g'modules/setup.distsed-I.'s/#_sha512 sha512module.c/_sha512 sha512module.c/g'modules/setup.dist############2. Specify the OpenSSL library to compile the new OpenSSL library CD OpenSSL-1.0. 2o./configure--prefix=/usr/local/ansible_python/Openssl_for_python make make install3. As Python compiles, you need to go to/usr/local/ssl/directory to find the OpenSSL library (see setup.py), so you need to create a new soft link to compile OpenSSL ln-s/usr/local/ansible_python/openssl_for_python/usr/local/SSL4. CD Python-2.7.15  ./configure–prefix=/usr/local/ansible_python/once the python make makes install is installed, you can install modules such as anshible for easy porting5. Put your own built-in OpenSSL library into the system shared library echo "/usr/local/ansible_python/openssl_for_ansible/lib ">>/etc/ld.so.conf.d/ansible.conf
Ldconfig6. Compress the compiled Python and OpenSSL to facilitate porting the tar-CVJF ansible_python.tar.bz2 Ansible_python7.
