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

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

    • Deactivate virtual-environment

      # in virtual-environment root dir
      deactivate

  • 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
