Manual Deployment

General deployment instructions for a hardware or cloud services environment

For automated deployment on AWS, see Ansible deployment.

Check your environment is prepared with General Requirements and Database Storage Requirements.

BlockScout requires a full archive node in order to import every state change for every address on the target network. For client specific settings related to a node running parity or geth, please see Client Settings.

Deployment Steps

1) git clone https://github.com/poanetwork/blockscout

2) cd blockscout

3) Setup default configurations: cp apps/explorer/config/dev.secret.exs.example apps/explorer/config/dev.secret.exs

cp apps/block_scout_web/config/dev.secret.exs.example apps/block_scout_web/config/dev.secret.exs

4) Update apps/explorer/config/dev.secret.exs

  • Linux: Update the database username and password configuration

  • Mac: Remove the username and password fields

  • Optional: Set up a default configuration for testing. cp apps/explorer/config/test.secret.exs.example apps/explorer/config/test.secret.exs

Example usage: Changing the default Postgres port from localhost:15432 if Boxen is installed.

5) If you have deployed previously, delete the apps/block_scout_web/priv/static folder. This removes static assets from the previous build.

6) Install dependencies. mix do deps.get, local.rebar --force, deps.compile, compile

7) If not already running, start postgres: pg_ctl -D /usr/local/var/postgres start

To check postgres status: pg_isready

8) Create and migrate database mix do ecto.create, ecto.migrate

If you have run previously, drop the previous database mix do ecto.drop, ecto.create, ecto.migrate

9) Install Node.js dependencies

  • cd apps/block_scout_web/assets; npm install && node_modules/webpack/bin/webpack.js --mode production; cd -

  • cd apps/explorer && npm install; cd -

10) Enable HTTPS in development. The Phoenix server only runs with HTTPS.

  • cd apps/block_scout_web

  • mix phx.gen.cert blockscout blockscout.local; cd -

  • Add blockscout and blockscout.local to your /etc/hosts

127.0.0.1 localhost blockscout blockscout.local
255.255.255.255 broadcasthost
::1 localhost blockscout blockscout.local

If using Chrome, Enable chrome://flags/#allow-insecure-localhost

11) Set your environment variables as needed.

CLI Example:

export COIN=DAI
export NETWORK_ICON=_network_icon.html
export ...

The ETHEREUM_JSONRPC_VARIANT will vary depending on your client (parity, geth etc). More information on client settings.

12) Return to the root directory and start the Phoenix Server. mix phx.server

13) Check your instance
