Deploy Django on Ubuntu 16.4 LTS

Preface

This note aims to simplify the route to deploy Django2.X<2 on Ubuntu 16 LTS server. It takes about 4 minutes.

Before you start your Ubuntu server, you'd better change your ssh port to another one, never use '22'. Because hackers will try many times to access your server. You can switch your ssh port by following scripts:

cd /etc/init.d/ssh
ls
sudo vim sshd_config # a configuration file like this
# in vim mode, type 'i' to insert
# annotate the default port setting as '# port 22'
# add a new line after 'port 22' as 'port 23442', just an example.
# after you've done above things
sudo /etc/init.d/ssh restart

Install Instruction

• Install & Configure MySql Server
  • Install

  sudo apt update
  sudo apt-get install mysql-server mysql-client

  • Configure

  service mysql status
  service mysql start #restart/stop

  • Initialize Databases

  mysql -u root -p
  mysql: create database Django_Database_Name default charset utf8 collate utf8_general_ci; # Set default charset as UTF-8 to prevent error in future

• Install Django
  • Install Dependencies: VirtualEnv(Optional)

  # install virtualenv
  sudo apt install virtualenv
  virtualenv Your_Django_App_Root_Name # e.g. Fucker
  cd Fucker
  source ./bin/activate # activate virtual-environment

  • Install Dependencies: Python3 + pip3

  sudo apt-get install python3
  sudo apt-get install python3-pip

  • Install Dependencies: uWSGI + Django

  pip3 install django uwsgi pillow --user # --user option to prevent Permission Denied Error in future

• Install Dependency: Nginx

sudo apt-get install nginx
systemctl nginx status # check nginx status
sudo apt install curl # test nginx
curl 127.0.0.1

Debug your site/app

• Upload your django files via SFTP, with the same port as ssh
• do following jobs:

source ./bin/activate
python3 manage.py makemigrations
python3 manage.py migrate
python3 manage.py createsuperuser
# set username, pwd, email
python3 manage.py runserver 0.0.0.0:8000
# then some error might occur

• Trouble shooting
  • Model fields error
    • check your field setting
    • check your mysql charset
  • MySql connection error
    • re-configure your mysql settings in settings.py
    • checkout your mysql service status
  • Not allowed ip or so
    • add your server public IP address to the settings.py in 'ALLOW' like list
  • makemigrations or migrate do not work well
    • use following scripts to clear your specific app's migrations cache

    python3 manage.py makemigrations --empty YOUR-APP-NAME
    python3 manage.py makemigrations
    python3 manage.py migrate
