Forever

forever

using a json file is flaky, instead in /root/forgone.sh

   #!/bin/sh
   forever stopall
   sleep 2
   fuser -KILL -k -n tcp 3002 
   forever --uid tokauth -a start /home/services/token-auth-server/server.js
   sleep 2
   fuser -KILL -k -n tcp 3009
   forever --uid bogged -a start /home/boggedbus/public_html/boggedbus/server/app.js
   sleep 2
   fuser -KILL -k -n tcp 1883 # mqtt
   fuser -KILL -k -n tcp 3332 # express
   fuser -KILL -k -n tcp 3333 # wss
   forever --uid geniot -a start /home/services/geniot/lib/index.js
   sleep 2
   fuser -KILL -k -n tcp 1642
   forever --uid hellossl -a start /home/services/hello/hello.js
   sleep 2
   forever list

and put it in @reboot of /var/spool/cron/crontab/root

   @reboot /root/forgone.sh 
   # m h  dom mon dow   command

running servers info can be seen in /root/appsServers2start.json. You stop them and restart them all like this

forever stopall
forever start ./appsServers2start.json

• /root/.forever/config.json has configuration for forever
• log files are in /root/.forever
