Error when joining a new node on cluster

Hi,

I have a cluster with 3 nodes, I’m setting up a 4th node to join the cluster, however need to have the same donor as the nodes number 3 only. Below is my my.cnf configuration and error that returns me to the log of the node 4.

MY.CNF - Node 4

[mysqld]

datadir=/var/lib/mysql
user=mysql
tmpdir=/tmp
server-id = 4

Path to Galera library

wsrep_provider=/usr/lib64/libgalera_smm.so

Cluster connection URL contains the IPs of node#1, node#2, node#3 and node#4

wsrep_cluster_address=gcomm://MYSQL01,MYSQL02,MYSQL03,MYSQL04

In order for Galera to work correctly binlog format should be ROW

binlog_format=ROW

MyISAM storage engine has only experimental support

default_storage_engine=InnoDB

This is a recommended tuning variable for performance

innodb_locks_unsafe_for_binlog=1

This changes how InnoDB autoincrement locks are managed and is a requirement for Galera

innodb_autoinc_lock_mode=2

wsrep_sst_donor=MYSQL03

Node #4 address

wsrep_node_address=MYSQL04

SST method

wsrep_sst_method=xtrabackup

Cluster name

wsrep_cluster_name=RHCLUSTER

Authentication for SST method

wsrep_sst_auth=“sstuser:pass”

ERROR node 4

Could anyone help me?

Have you checked network connectivity between those nodes? Basically, at least the TCP ports 4567 (default group comms), 4444 (SST), 4568 (IST) must be open between all nodes.
