1 Install Apache with Mod_WSGI2 Make sure we have all the Python extensions set so

Apache can see them3 Configure firewall so that only http https and ssh are

available to outside world4 Install Postgresql and plugins5 update PG_hbaconf create db user create db user

password set up access privs and a test account6 Create DB give user permissions to the DB7 Set up a git repository and then figure out how to

structure and deploy8 Now I can write code - hello world then database

connection then real app9 Get it working with a public DNS

10 Now you are stuck maintaining the machine
