Automatic Restarts and Monitoring

to get koisan-chian node running as a background service on Ubuntu can use supervisor for monitoring

• Install supervisor on ubuntu

$ apt-get install supervisor

Finally we have to add a configuration file to supervisor to let it know that it should run geth, Create /etc/supervisor/conf.d/geth.conf and fill it with:

[program:geth]
command=/path/to/koisan-chain/build/bin/geth --fast --http --http.addr 127.0.0.1 --http.port 8545 --http.corsdomain * --http.api admin,db,eth,debug,miner,net,shh,txpool,personal,web3
autostart=true  
autorestart=true  
stderr_logfile=/var/log/supervisor/koisan.err.log  
stdout_logfile=/var/log/supervisor/koisan.out.log  

• Now just restart supervisor to startup geth:

$ supervisorctl reload  

Boom! You can now attach a console to your running geth instance by typing geth attach. You can then query it using the standard commands.
