The my.cnf is off of the shelf:
# The Percona XtraDB Cluster 5.7 configuration file.
# * IMPORTANT: Additional settings that can override those from this file!
# The files must end with '.cnf', otherwise they'll be ignored.
# Please make any edits and changes to the appropriate sectional files

I cannot attach the log file as I am a new user. The only error that stands out is:

Here is the contents of wsrep.cnf:
# Path to Galera library
# Cluster connection URL contains IPs of nodes
#If no IP is found, this implies that a new cluster needs to be created,
#in order to do that you need to bootstrap this node
# In order for Galera to work correctly binlog format should be ROW
# MyISAM storage engine has only experimental support
# Slave thread to use
# This changes how InnoDB autoincrement locks are managed and is a requirement for Galera
# Node IP address
# Cluster name
#If wsrep_node_name is not specified, then system hostname will be used
