I'm installing a galera cluster using mariadb 10.3.13 with two nodes in redhat 8.1 server. I enabled ports 3306, 4567, 4568 y 4444 ports. selinux is disabled. firewall disabled. The first node is started by galera_new_cluster. It works. When I try to start the second node by systemctl start mysql. It delays to finish the process. The data is not replicating but I see no errors. By tcpdump I see traffic incomming to second node but it's not replicating.

What can I do?

server.cnf configuration:

[server]

[mysqld]
log_error=/var/log/mysql/mysql_error.log

[galera]
wsrep_on=ON
wsrep_provider=/usr/lib64/galera/libgalera_smm.so
wsrep_cluster_address=gcomm://172.24.10.53,172.24.10.54
binlog_format=row
default_storage_engine=InnoDB
innodb_autoinc_lock_mode=2

mysql_error.log

  • How much data in the dataset? Are you using "replicate" to indicate the initial cloning of the data from one Galera node to another? (As opposed to "replication" between a Master and a Slave?)

  • 60gb. So I tried uninstalling galera and installed again (fresh installation) to make discards but I have same results. It's delaying. Feb 2, 2020 at 15:43

Ok, I know what happened. What I did:

1) vi /etc/selinux/config

2) Change state to from enforcing to disabled

3) Apply init 6 (restart server)
