# In order to get pm2 to startup your services on boot, I ran:
#  run sudo pm2 startup 
# which will create the necessary files for your system to run pm2 when you boot your machine.

# new commands as root ---
# sudo pm2 start --interpreter="Rscript" /share/github/api/run-api.R
# sudo pm2 list
# sudo pm2 save
# sudo pm2 logs run-api --lines 1000
# sudo pm2 restart run-api

# old commands as shiny ---
# sudo -u shiny pm2 restart run-api
# sudo -u shiny pm2 stop run-api
# sudo -u shiny pm2 start run-api
# sudo -u shiny pm2 logs run-api --lines 1000
# sudo -u shiny pm2 start --interpreter="Rscript" /share/github/api/run-api.R
