Hello. Please help me to configure nodes.
I’m trying to make two test nodes. OS is Ubuntu 13.10 in Virtual Box (two machines), i have installed percona-xtradb-cluster-56.
Here is configs:
Configs:
node1:
[mysqld]
user=mysql
wsrep_provider=/usr/lib/libgalera_smm.so
wsrep_cluster_address=gcomm://10.10.10.2,10.10.10.3
wsrep_cluster_name=my_cluster
wsrep_node_name=node1
wsrep_slave_threads=2
binlog_format=ROW
default_storage_engine=InnoDB
innodb_autoinc_lock_mode=2
innodb_locks_unsafe_for_binlog=1
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
#basedir = /usr/
#datadir = /var/lib/mysql
datadir = /mnt/data
tmpdir = /tmp
log_error = /var/log/mysql/error.log
expire_logs_days = 10
max_binlog_size = 100M
node2:
[mysqld]
user=mysql
wsrep_provider=/usr/lib/libgalera_smm.so
wsrep_cluster_address=gcomm://10.10.10.2,10.10.10.3
wsrep_cluster_name=my_cluster
wsrep_node_name=node2
wsrep_slave_threads=2
binlog_format=ROW
default_storage_engine=InnoDB
innodb_autoinc_lock_mode=2
innodb_locks_unsafe_for_binlog=1
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
#basedir = /usr/
#datadir = /var/lib/mysql
datadir = /mnt/data
tmpdir = /tmp
log_error = /var/log/mysql/error.log
expire_logs_days = 10
max_binlog_size = 100M
I have executed
sudo /etc/init.d/apparmor teardown
on both nodes.
Firstly i run
sudo /etc/init.d/mysql bootstrap-pxc
on the first node. Secondly
sudo /etc/init.d/mysql start
on the second node and after that i get error.
Here are last ~80 strings from /var/log/mysql/error.log from second node:

Also I even can’t connect to the first node from the second (mysql -h 10.10.10.2 -u root tell me something like “Host 10.10.10.3 is not allowed to connect to this MySQL server”. bind-address 0.0.0.0 does not help).
