Verium Mining Pool Scripts

This repo contains a bunch of scripts that should aid in installing a Verium mining pool. They are grouped together in their respective subfolders in scripts/.

These scripts have been tested on an Ubuntu 16.04 vanilla install.

Each of these scripts generates passwords at random. Each password will be stored in /root/<service>_passwords.txt, where service is the relevant serivice (i.e., mysql, veriumd, or nomp).

Known Problems

I have had some issues when I installed mysql-server before the veriumd wallet. That would result in compilation issues. Not sure how that happened, but be sure to install veriumd before mysql..

Veriumd

Veriumd is the daemon that runs the verium wallet. Installing it is pretty straightforward. Run the install.sh script in scripts/veriumd and wait for it to finish.

All the passwords will be stored in /root/veriumd_passwords.txt. The first password will be the unix user password, and the second is the veriumd rpc password.

You can make the system startup by copying the systemd file located at systemd/veriumd.service to /etc/systemd/system/, and then start it by typing systemctl start veriumd.service.

Once the service is online, you can bootstrap it by issueing veriumd -conf=/etc/veriumd/verium.conf bootstrap false, and afterwards restart the service.

You can verify the system works by executing vveriumd -conf=/etc/veriumd/verium.conf getinfo. Be patient here, it might take a while.

Credentials

The RPC username is veriumrpc, and the password is stored in the aforementioned textfile.

The unix username is veriumd, and the password is stored in the aforementioned textfile.

MySQL Server

MySQL server is installed by running scripts/mysql/install.sh.

Credentials

The root password is stored in /root/mysql_password.txt.

Nomp

Nomp is the stratum software that divides work up between all the users of your pool.

It requires node.js 0.10 to run, so we will be using nvm to install that for us.

Run it by executing scripts/nomp/install.sh rootdbpassword.

The NOMP script needs root database access, so you need to pass that as a paramter to the script!

The script will install nvm for the nomp user.

You can verify the system works by doing the following.

su nomp
cd ~/nomp
node init.js

You should see no errors, maybe except the one for paymentPRocessing.

One thing you should configure is the verium wallet address. Normally, you can get the veriumd address by issuing the following command.

veriumd -conf=/etc/veriumd/verium.conf getaddressesbyaccount "" | awk '/"/ {print $1;}' | cut -d\" -f2 > ~/verium_address.txt

This will put the verium address in a text file. Place the contents of that file into the configuration file located at /home/nomp/nomp/pool_config/verium.json.

Finally, you should fill in the daemon credentials for the veriumd service into the same file.

Credentials

The unix user for nomp is nomp, and its password is stored in /root/nomp_passwords.txt.

We also have a password for the database user (nompuser).

MPOS

MPOS is the webinterface part for the mining pool. This requires some additional setup.

First run the script in scripts/mpos/install.sh.

Finally, you need to change some values in the configuration file of MPOS. This is located at /var/www/MPOS/include/config/global.inc.php.

The lines you need to change are the following. You need the RPC password, which is stored in /root/veriumd_passwords.txt.

$config['wallet']['password'] = 'rpcpasswordhere'; // Insert your RPC password here.

$config['gettingstarted']['stratumurl'] = 'yourdomainhere.com';

Mail

You will need to setup your server to be able to send emails to users. In this guide we are going to use a third-party smtp server. Chances are, if you are a member of gandi.net or others, you can just use their SMTP server. This guide assumes gandi.net, since that is where I have taken out my domain name.

apt-get install postfix mailutils

When asked, select Internet Site, and when asked for your hostname, enter your full domain name. For example myserver.mydomain.com.

Create the file /etc/postfix/sasl_passwd. Assuming the SMTP you can use its IP is mail.gandi.net, and the username for your account is myusername@gandi.net and mypassword, add this line:

[mail.gandi.net]:587 myusername@gadni.net:mypassword

after you have done that, run

sudo postmap /etc/postfix/sasl_passwd

Note that you now have your SMTP credentials as plain text on your server. Secure this as much as possible.

sudo chown root:root /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db
sudo chmod 0600 /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db

Then open up the file /etc/postfix/main.cf and add the following lines.

myhostname = myserver.mydomain.com
relayhost = [mail.gandi.net]:587

After all this, you should be able to send an e-mail to yourself. Try this out:

echo "body of your email" | mail -s "This is a Subject" -a "From: pool@pool.com" me@me.com

Cronjobs

MPOS requires you to run some cronjobs. Mostly for paying out your users (important, no?), and statistics. You can just smack those into your crontab. You can edit it with sudo crontab -e.

Add the following lines:

* * * * * /var/www/MPOS/cronjobs/run-statistics.sh
* * * * * /var/www/MPOS/cronjobs/run-payout.sh 
* * * * * /var/www/MPOS/cronjobs/run-maintenance.sh
