NDB Cluster no nodes connect

I'm trying to set up a simple three node cluster with a single management server, a data node, and a mysql node, all on different VMs. Nothing will connect to anything. I've verified that firewalls are down to eliminate them from the equation.

Node 2 is my data node. When I run ndbd to connect to the management server, I get this on the management server: Node 2: Forced node shutdown completed. Occured during startphase 0. Initiated by signal 9.

Node 3 is my MySQL server. It simply never connects, here is the configuration in the etc/my.cnf file:

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
default_storage_engine=ndbcluster
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[mysql_cluster]
ndb-connectstring=10.0.1.5





I really need help here, I'm not sure when I'm doing wrong.

Thanks!
