XtraDB Initial SST fails.


I’ve been following the Ubuntu installation guide, but have hit a few problems when trying to bring the second node into the cluster. The first node is bootstrapped and seems to be fine, but when I start the second node the initial State transfer fails.

Packages (same on both nodes)
ii percona-xtradb-cluster-server-5.6 5.6.21-25.8-938.trusty
ii percona-xtrabackup 2.2.9-5067-1.trusty


# Path to Galera library
# Cluster connection URL
# In order for Galera to work correctly binlog format should be ROW
# MyISAM storage engine has only experimental support
# This changes how |InnoDB| autoincrement locks are managed and is a requirement for Galera
# Authentication for SST method
# Node #1 address
# SST method
# Cluster name
innodb_data_file_path = ibdata1:100M:autoextend
## You may want to tune the below depending on number of cores and disk sub
innodb_flush_method = O_DIRECT
## avoid statistics update when doing e.g show tables

I’ve seen several over posts similar to this, and so heres the permissions from my.cnf:
-rw-r–r-- 1 mysql root 4879 Feb 24 17:15 /etc/mysql/my.cnf
…and I do have datadir also, although it wasn’t included in the snip above…
datadir = /var/lib/mysql

Could I please have some suggestions here? As a newcomer it is virtually impossible to troubleshoot, and this is a fairly basic setup following a guide on your website.

I figured out the problem. When adding the grant for the sstuser, I added it at, not ‘localhost’. I just added another grant for sstuser@localhost and it now works.

This can be closed.



I don’t know if I am the only one interpreting this like this … but here it goes …
According to what you wrote on the TOP . -> -> -> ->

On your NAT you are already forwarding the non standard ports to the standard ports .
Now if what you want to do is used the non standard ports on the configuration let us know.

I had the same issue.
