This guide covers installing Sentinel onto an Masternode in Ubuntu 14.04 or 16.04.

Make sure Python version 2.7.x or above is installed:

python --version

Update system packages and ensure virtualenv is installed:

$ sudo apt-get update
$ sudo apt-get -y install python-virtualenv

Make sure the local SunCoin daemon is running:

$ suncoin-cli getinfo | grep version

Clone the Sentinel repo and install Python dependencies.

$ git clone https://github.com/suncoin-network/sentinel.git
$ cd sentinel
$ virtualenv ./venv
$ ./venv/bin/pip install -r requirements.txt

Set up a crontab entry to call Sentinel every minute:

$ crontab -e

In the crontab editor, add the lines below, replacing '/home/YOURUSERNAME/sentinel' to the path where you cloned sentinel to:

* * * * * cd /home/YOURUSERNAME/sentinel && ./venv/bin/python bin/sentinel.py >/dev/null 2>&1

For debugging you can use:

* * * * * cd /home/sentinel && SENTINEL_DEBUG=1 ./venv/bin/python bin/sentinel.py --bypass-schedule >> sentinel.log 2>&1

An alternative (non-default) path to the suncoin.conf file can be specified in sentinel.conf:

suncoin_conf=/path/to/suncoin.conf

To view debug output, set the SENTINEL_DEBUG environment variable to anything non-zero, then run the script manually:

$ SENTINEL_DEBUG=1 ./venv/bin/python bin/sentinel.py
