secode node and third node can't join in Galera cluster

[lee a]

Hello everyone

I am new to Galera, I have been Setup a 3-nodes Galera cluster.

But when I am going to start

the first node started up normally  with command:  galera_new_cluster

But the second node and the third node started  failed with command:

#systemctl start mariadb.

Job for mariadb.service failed because a fatal signal was delivered to the control process. See "systemctl status mariadb.service" and "journalctl -xe" for details.

three nodes OS and mariadb version are the same:

OS: CentOS Linux release 7.6.1810 (Core)

Mariadb and Galera version:

MariaDB-client.x86_64                 10.6.8-1.el7.centos            
MariaDB-common.x86_64                 10.6.8-1.el7.centos            
MariaDB-compat.x86_64                 10.6.8-1.el7.centos            
MariaDB-server.x86_64                 10.6.8-1.el7.centos            
galera-4.x86_64                       26.4.11-1.el7.centos

three nodes  config and logs are  showed in attachment,

In your logs for node3 you can see;

    [ERROR] WSREP: Failed to read 'ready <addr>' from: wsrep_sst_rsync --role 'joiner' --address '10.7.201.213' ...
    [ERROR] WSREP: Process completed with error: wsrep_sst_rsync --role 'joiner' --address '10.7.201.213' ...
    [ERROR] WSREP: Failed to prepare for 'rsync' SST. Unrecoverable.
    [ERROR] WSREP: SST request callback failed. This is unrecoverable, restart required.

Start trouble shooting there.

Why can't it establish connection with 10.7.201.213?

Are all firewall ports open? (4567,4568,4444)
