ASIC Sentry - How to deploy manually?

[1] Copy from release directory `prod/rel/asic_sentry` to `/opt/asic_sentry`

$ cp _build/prod/rel/asic_sentry /opt -rf

[2] Directory structure of `/opt/asic_sentry`

➜ asic_sentry (master) ✔ tree -L 1 /opt/asic_sentry

/opt/asic_sentry
├── bin
├── erts-15.0
├── lib
└── releases

[3] Test run with script before working with systemd service.

[4] Create systemd service `/etc/systemd/system/asic_sentry.service`

[Unit]
Description=ASIC Sentry
After=network.target

[Service]
WorkingDirectory=/opt/asic_sentry
EnvironmentFile=/etc/asic_sentry/asic_sentry.env
ExecStart=/opt/asic_sentry/bin/server
ExecStop=/opt/asic_sentry/bin/mining_rig_monitor stop
User=nguyenvinhlinh
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target

[5] Create environment file `/etc/asic_sentry/asic_sentry.env`

SECRET_KEY_BASE=
DATABASE_FILE=/opt/asic_sentry_data/data.db
PORT=4001
PHX_HOST=127.0.0.1

Regarding PHX_HOST, modify it to match domain/ip which web browser calling. if not, there will be an error.

[error] Could not check origin for Phoenix.Socket transport.
Origin of the request: http://192.168.1.9:4000
This happens when you are attempting a socket connection to
a different host than the one configured in your config/
files. For example, in development the host is configured
to "localhost" but you may be trying to access it from
"127.0.0.1". To fix this issue, you may either:
  1. update [url: [host: ...]] to your actual host in the
     config file for your current environment (recommended)
  2. pass the :check_origin option when configuring your
     endpoint or when configuring the transport in your
     UserSocket module, explicitly outlining which origins
     are allowed:
        check_origin: ["https://example.com",
                       "//another.com:888", "//other.com"]

and run systemctl daemon-reload

[6] Start systemd service named `asic_sentry`

systemctl enable --now asic_sentry

[7] To view log

journalctl -f -u asic_sentry.service
