[Elixir003] managing config through environment variables (environment Variables)

In the config of elixir, we sometimes use some configuration items that we don't want to expose, and the usual practice is like Phoenix

#config/  prod.exsuse mix.config ... # Finally Import the config  /  prod.secret.exs# which should be versioned separately." Prod.secret.exs "

Above, we can put items that should not be exposed (such as database Passwd,auth_token ... All of these important items are written in the Prod.secret.exs (link visible example)

Let's put prod.secret.exs this file out of the project's version management, and run a git repository separately.

but sometimes we don't want to do that again, and there's a way (and it feels better than the method above)

is to write all the items that should be written in Prod.sesret.exs into the environment variables of the system.

#config/  prod.exsuse Mix.config....config:application_name, Applicationname.repo,  adapter: Ecto.Adapters.MySQL,  username:System.get_env ("Prod_repo_username"),  password:System.get_env ( "Prod_repo_password"),  database:System.get_env ("Prod_repo_database"),  hostname: System.get_env ("Prod_repo_hostname") ...

Only need to be on the server

#prod. env
Export prod_repo_username= ' USERNAME 'export prod_repo_password= ' loveyou 'export prod_ Repo_database= ' DATABASE 'export prod_repo_hostname= ' 11.11.11.11 '

Only need to first

>Source prod.env>iex-s Mix

This allows the configuration of the elixir to be managed through environment variables.
