Once you have your packages installed to your custom pypi server, you can have your pip refer to it like so:

a. If you use requirements.txt to install your module:

Sample requirements.txt:

--find-links http://10.10.161.9:8080/packages/
custom-python-package==0.1.1
b. If you use setup.py to install your module:
# Sample setup.py
from setuptools import setup

with open('requirements.txt') as f:
    required = f.read().splitlines()

setup(
    name='spidey-web',
    version='1.0',
    author='Spiderman',
    author_email='spiderman@gmail.com',
    description='A business project for Spiderman',
    test_suite='nose.collector',
    dependency_links=['http://10.11.12.13:8080/packages/'],
    install_requires=required,
    url='https://github.com/Spiderman/spidey-web'
)

Sample requirements.txt:

custom-python-package==0.1.1
But for all of that to work you need to setup PyPi to look into the custom PyPi server:

Configuration for locating packages in pypi server:

a. Make sure pip is installed.
b. Create a file: /home/spiderman/.pip/pip.conf with contents:

[global]
extra-index-url = http://10.11.12.13:8080/simple

c. If you are using Pycharm then create: /root/.pip/pip.conf with contents mentioned below:

[global]
extra-index-url = http://10.11.12.13:8080/simple

NOTE: Replace 10.11.12.13 the ip address where your PyPi server is running

d. export PYTHONPATH=/usr/local/lib/python2.7/dist-packages

To be able to deploy to custom PyPi server:

To be able to deploy to the custom pypi server, you need to create a file called /home/spiderman/.pypirc:

[distutils]
index-servers = pyrack

[pyrack]
repository: http://10.10.161.9:8080
username: <username>
password: <password>

And you are done. Now you can deploy and install from your custom pypi server.
