#Konfigurasi Virtual Environment

  1. Jalankan vagrant dan masuk
vagrant up
vagrant ssh

  1. Install virtualenv dengan perintah

    pip install virtualenv

    atau

    easy_install install virtualenv

  2. Buat direktori project baru di home

    mkdir ~/projects && cd ~/projects/

  3. Buat virtual environment baru dengan nama venv

    virtualenv venv

  4. Aktivasi virtual environment dengan perintah

source venv/bin/activate
  1. Install dependensi
  • buat file requirements.txt yang berisikan:

ago==0.0.6

Cython==0.22.1

Django==1.4

docopt==0.4.0

falcon==0.1.10

greenlet==0.4.7

gunicorn==19.2.1

lxml==3.4.2

mandrill==1.0.57

meinheld==0.5.7

MySQL-python==1.2.5

oauthlib==0.7.2

Pygments==2.0.2

python-memcached==1.53

python-mimeparse==0.1.4

redis==2.10.3

requests==2.4.3

requests-oauthlib==0.4.1

schedule==0.3.1

shortuuid==0.4.2

six==1.7.3

tweepy==3.2.0

twython==3.2.0

wheel==0.24.0 ```

  • jalankan perintah berikut untuk menginstall dependensi 
    pip install -r requirements.txt
  • bila terjadi beberapa pesan kesalahan sebagai contoh: 
    sh: 1: mysql_config: not found
    install 
    sudo apt-get install libpython-dev

sudo apt-get install libmysqlclient-dev

sudo apt-get install libxml2-dev libxslt-dev python-dev
  1. Clone app dari github 
    git clone [email protected]:Aksaramaya/latihan.git
  2. install supervisor
    • instalasi
    pip install supervisor --pre
    • buat file konfigurasi
    echo_supervisord_conf > supervisord.conf
    • berikut contoh file konfigurasi setelah dirubah
      ; Sample supervisor config file.
  ;
  ; For more information on the config file, please see:

  ;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
