This is an updated version of installation instructions of open-ethereum-pool and its forks, you can adapt to your coin!
- Support for HTTP and Stratum mining
- Detailed block stats with luck percentage and full reward
- Failover geth instances: geth high availability built in
- Modern beautiful Ember.js frontend
- Separate stats for workers: can highlight timed-out workers so miners can perform maintenance of rigs
- JSON-API for stats
- PPLNS block reward
- Multi-tx payout at once
- Beautiful front-end highcharts embedded
- Ether-Proxy HTTP proxy with web interface
- Stratum Proxy for Ethereum
Dependencies:
- go >= 1.10
- redis-server >= 2.8.0
- nodejs >= 4 LTS
- nginx
- geth (multi-geth)
I highly recommend to use Ubuntu 16.04 LTS.
$ adduser clopool
$ usermod -aG sudo clopool
$ su clopool
$ cd ~
$ sudo apt-get update -y
$ sudo apt-get install -y software-properties-common build-essential unzip curl git nano
$ sudo apt-get upgrade -y
$ sudo apt-get -y autoremove apache2
$ sudo add-apt-repository -y ppa:gophers/archive
$ sudo apt-get -y update
$ sudo apt-get -y install golang-1.10-go
$ sudo ln -s /usr/lib/go-1.10/bin/go /usr/local/bin/go
$ sudo apt-get -y install redis-server
It is recommended to bind your DB address on 127.0.0.1 or on internal ip. Also, please set up the password for advanced security!!!
$ sudo nano /etc/redis/redis.conf
Uncomment bind 127.0.0.1
$ echo "password" | sha256sum
copy the generated password and paste in the following
$ sudo nano /etc/redis/redis.conf
uncomment this line requirepass foobared
replace foobared with the generated password you copied.
$sudo service redis-server restart
To check that Redis is working, use the Redis command line.
$ redis-cli
to authenticate, do the following in redis-cli 'auth yourHashedString'
$ sudo apt-get install nginx
Search on Google for nginx-setting
This will install the latest nodejs
$ sudo curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
$ sudo apt-get install -y nodejs
MAke sure to compile the appropriate version of geth for the coin you're pool is for
$ sudo wget https://github.com/ethereumsocial/multi-geth/releases/download/v1.8.10/multi-geth-linux-v1.8.10.zip
$ sudo unzip multi-geth-linux-v1.8.10.zip
$ sudo mv geth /usr/local/bin/geth
If you use Ubuntu, it is easier to control services by using serviced.
$ sudo nano /etc/systemd/system/callisto.service
Copy the following example
[Unit]
Description=Callisto for Pool
After=network-online.target
[Service]
ExecStart=/usr/local/bin/geth --callisto --cache=1024 --extradata "Mined by <your-pool-domain>" --ethstats "<your-pool-domain>:Callisto@clostats.net" --unlock="Wallet_Address" --password="/home/<your-user-name>/.walletpass" --rpc --rpcaddr 127.0.0.1 --rpcapi eth,net,web3
User=<your-user-name>
[Install]
WantedBy=multi-user.target
Then run multi-geth by the following commands
$ sudo systemctl enable callisto
$ sudo systemctl start callisto
If you want to debug the node command
$ sudo systemctl status callisto
To monitor synchronization progress
$ sudo journalctl -f -u callisto
Run console
$ geth attach
You can create your own shortcut for geth attach on /usr/local/bin/gethattach for example, make sure to include --datadir for the ipc
$ sudo nano /usr/local/bin/attachgeth.sh
/usr/local/bin/geth attach ipc://home/<your-user-name>/.ethereum/callisto/geth.ipc
$ chmod 755 /usr/local/bin/attachgeth.sh
Now you can use atachgeth.sh from anywhere in your servers.
Register pool account and open wallet for transaction. This process is always required, when the wallet node is restarted.
> personal.newAccount()
> personal.unlockAccount(eth.accounts[0],"password",40000000)
> exit
Save wallet password in /home/pooluser/.walletpass and embed it in the pool.service line
$ sudo git clone https://github.com/chainkorea/open-callisto-pool
$ sudo cd open-callisto-pool
$ sudo make all
If you get a open-callisto-pool after ls ls ~/open-callisto-pool/build/bin/, the installation has completed.
Here, you can use phatblinkie's service_installer.sh (if you know how to use it)
Or, do the regular:
$ mv config.example.json config.json
$ nano config.json
Set up based on commands below.

}This file has settings for, API, 1x Stratum, Payout, Unlocker, all combined together to run as one service
- Stratum is the node miners will connect two with a set difficulty
- API is the service that submits/reports stats to the website
- Unlocker is the service that does the accounting based on the payout scheme, which miner gets how much of the block, and writes down to DB
- Payout is the service that does the actual transactions to miners.
If you are distributing your pool deployment to several servers or processes, create several configs and disable unneeded modules on each server. (Advanced users)
I recommend this deployment strategy:
- Mining instance - 1x (it depends, you can run one node for EU, one for US, one for Asia)
- Unlocker and payouts instance - 1x each (strict!)
- API instance - 1x
It is required to run pool by serviced. If it is not, the terminal could be stopped, and pool doesn’t work.
$ sudo nano /etc/systemd/system/clopool.service
Copy the following example
[Unit]
Description=Callisto
After=callisto.target
[Service]
Type=simple
ExecStart=/home/clopool/open-callisto-pool/build/bin/open-callisto-pool /home/clopool/open-callisto-pool/config.json
[Install]
WantedBy=multi-user.target
Then run pool by the following commands
$ sudo systemctl enable clopool
$ sudo systemctl start clopool
If you want to debug the node command
$ sudo systemctl status clopool
Backend operation has completed so far. If you want to separate each service of the pool in a separate process, then you need to make different configs and a service for each
Firewall should be opened to operate this service. Whether Ubuntu firewall is basically opened or not, the firewall should be opened based on your situation. You can open firewall by opening 80,443,8080,8888,8008.
$ nano ~/open-callisto-pool/www/config/environment.js
Make some modifications in these settings.
BrowserTitle: 'Callisto Mining Pool',
ApiUrl: '//your-pool-domain/',
HttpHost: 'http://your-pool-domain',
StratumHost: 'your-pool-domain',
PoolFee: '1%',
The frontend is a single-page Ember.js application that polls the pool API to render miner stats.
$ cd ~/open-callisto-pool/www
$ sudo npm install -g ember-cli@2.9.1
$ sudo npm install -g bower
$ sudo chown -R $USER:$GROUP ~/.npm
$ sudo chown -R $USER:$GROUP ~/.config
$ npm install
$ bower install
$ ./build.sh
$ cp -R ~/open-callisto-pool/www/dist ~/www
As you can see above, the frontend of the pool homepage is created. Then, moved to the directory www which serves the file.
Change favicon.ico file to your taste (act special)
$ sudo nano /etc/nginx/sites-available/default
Modify based on configuration file.
server {
listen 80 default_server;
listen [::]:80 default_server;
root /home/<your-user-name>/www;
index index.html index.htm index.nginx-debian.html;
server_name _;
location / {
try_files $uri $uri/ =404;
}
location /api {
proxy_pass http://127.0.0.1:8080/api;
}
}
After setting nginx is completed, run the command below.
$ sudo service nginx restart
Type your homepage address or IP address on the web. If you face screen without any issues, pool installation has completed.
This guide was originally referred from digitalocean - How To Secure Nginx with Let's Encrypt on Ubuntu 16.04
First, install the Certbot's Nginx package with apt-get
$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt-get update
$ sudo apt-get install python-certbot-nginx
And then open your nginx setting file, make sure the server name is configured!
$ sudo nano /etc/nginx/sites-available/default
. . .
server_name <your-pool-domain>;
. . .
Change the _ to your pool domain, and now you can obtain your auto-renewed SSL certificate for free!
$ sudo certbot --nginx -d <your-pool-domain>
Now you can access your pool's frontend via https! Share your pool link!
- Unlocking and payouts are sequential, 1st tx go, 2nd waiting for 1st to confirm and so on. You can disable that in code. Carefully read
docs/PAYOUTS.md. - Also, keep in mind that unlocking and payouts will halt in case of backend or node RPC errors. In that case check everything and restart.
- You must restart module if you see errors with the word suspended.
- Don't run payouts and unlocker modules as part of mining node. Create separate configs for both, launch independently and make sure you have a single instance of each module running.
- If
poolFeeAddressis not specified all pool profit will remain on coinbase address. If it specified, make sure to periodically send some dust back required for payments. - DO NOT OPEN YOUR RPC OR REDIS ON 0.0.0.0!!! It will eventually cause coin theft.
