Can anyone give me an idea why my replication doesn't work? (I'm using MariadB-galera-server-5.5).
I'm following exactly these instructions:
sudo nano /etc/mysql/conf.d/cluster.cnf
[mysqld]
query_cache_size=0
binlog_format=ROW
default-storage-engine=innodb
innodb_autoinc_lock_mode=2
query_cache_type=0
bind-address=0.0.0.0
wsrep_provider=/usr/lib/galera/libgalera_smm.so
wsrep_cluster_name="test_cluster"
wsrep_cluster_address="gcomm://first_ip,second_ip,third_ip"
wsrep_sst_method=rsync
wsrep_node_address="node_ip"
wsrep_node_name="node_name"
sudo nano /etc/mysql/debian.cnf
[client]
host = localhost
user = debian-sys-maint
password = 03P8rdlknkXr1upf
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = debian-sys-maint
password = 03P8rdlknkXr1upf
socket = /var/run/mysqld/mysqld.sock
basedir = /usr
sudo service mysql stop
sudo service mysql start --wsrep-new-cluster
sudo service mysql start
My error log shows this:
sudo tail -f /var/log/mysqld.error.log

Please use ‘--log-basename=#’ or ‘--retay-log=mysqld-relay-bin’ to avoid this problem.
