User

  1. adduser <username>
  2. sudo usermod -aG sudo <username>

make user login without password

  1. sudo EDITOR=vim visudo

  2. append line:

    User_Alias  ADMIN = ubuntu
    ADMIN       ALL = (ALL) NOPASSWD: ALL
    

ssh

  1. ssh-keygen
  2. cat ~/.ssh/id_rsa.pub
  3. ssh-copy-id username@remote_host or ~/.ssh/authorized_keys

Local ssh config

  1. vim ~/.ssh/config
Host gitlab
    HostName gitlab.com
    IdentityFile ~/.ssh/gitlab_rsa

PIP

  1. wget https://bootstrap.pypa.io/get-pip.py
  2. python get-pip.py

Ref: https://pip.pypa.io/en/stable/installing/

Virtualenv

  1. pip install virtualenvwrapper
  2. source /usr/local/bin/virtualenvwrapper.sh

-> better to use pipenv instead

command=/home/ubuntu/.virtualenvs/sigrid/bin/gunicorn testprep.wsgi
directory = /home/ubuntu/testprep/
stdout_logfile = /home/ubuntu/testprep/log/gunicorn_stdout.log
stderr_logfile = /home/ubuntu/testprep/log//gunicorn_stderr.log
user = ubuntu
redirect_stderr = True
autostart=true
autorestart=true
