This portal is an extremely efficient, highly scalable, all-in-one, easy to setup cryptocurrency mining pool written entirely in Node.js. It contains a stratum poolserver; reward/payment/share processor; and a (not yet completed) responsive user-friendly front-end website featuring mining instructions, in-depth live statistics, and an admin center.
Follow the build/install instructions for your coin daemon. Your coin.conf file should end up looking something like this:
daemon=1
rpcuser=litecoinrpc
rpcpassword=securepassword
rpcport=19332
For redundancy, its recommended to have at least two daemon instances running in case one drops out-of-sync or offline,
all instances will be polled for block/transaction updates and be used for submitting blocks. Creating a backup daemon
involves spawning a daemon using the -datadir=/backup command-line argument which creates a new daemon instance with
it's own config directory and coin.conf file. Learn about the daemon, how to use it and how it works if you want to be
a good pool operator. For starters be sure to read:

}You can create as many of these pool config files as you want (such as one pool per coin you which to operate). If you are creating multiple pools, ensure that they have unique stratum ports.
For more information on these configuration options see the pool module documentation
- In
config.jsonset the port and password forblockNotifyListener - In your daemon conf file set the
blocknotifycommand to use:
node [path to cli.js] [coin name in config] [block hash symbol]
Example: inside dogecoin.conf add the line
blocknotify=node /home/nomp/scripts/cli.js blocknotify dogecoin %s
Alternatively, you can use a more efficient block notify script written in pure C. Build and usage instructions are commented in scripts/blocknotify.c.
node init.js- Use something like forever to keep the node script running in case the master process crashes.
- Use something like redis-commander to have a nice GUI for exploring your redis database.
- Use something like logrotator to rotate log output from NOMP.
- Use New Relic to monitor your NOMP instance and server performance.
When updating NOMP to the latest code its important to not only git pull the latest from this repo, but to also update
the node-stratum-pool and node-multi-hashing modules, and any config files that may have been changed.
- Inside your NOMP directory (where the init.js script is) do
git pullto get the latest NOMP code. - Remove the dependenices by deleting the
node_modulesdirectory withrm -r node_modules. - Run
npm updateto force updating/reinstalling of the dependencies. - Compare your
config.jsonandpool_configs/coin.jsonconfigurations to the latest example ones in this repo or the ones in the setup instructions where each config field is explained. You may need to modify or add any new changes.
