MariaDB / MySQL galera群集节点不会join

我正在build立一个MariaDB Galera集群，我似乎无法让节点相互连接。 他们都开始没有错误，但似乎从来没有join，状态总是断开：

MariaDB [(none)]> show status like 'wsrep%'; +--------------------------+----------------------+ | Variable_name | Value | +--------------------------+----------------------+ | wsrep_cluster_conf_id | 18446744073709551615 | | wsrep_cluster_size | 0 | | wsrep_cluster_state_uuid | | | wsrep_cluster_status | Disconnected | | wsrep_connected | OFF | | wsrep_local_index | 18446744073709551615 | | wsrep_provider_name | | | wsrep_provider_vendor | | | wsrep_provider_version | | | wsrep_ready | ON | +--------------------------+----------------------+ 

第一个节点是以“sudo service mysql start -wsrep-new-cluster”（也尝试像-wsrep_cluster_address = gcomm：//一样传入群集地址），并将空地址列表放入my.cnf

第二个节点是以my.cnf中的集群地址“sudo service mysql start”作为gcomm：//172.16.56.130,172.16.56.131

无论集群状态总是“断开”，集群大小为0。

• MariaDb的pipe理员密码似乎不起作用
• Centos 7.由于优先级，Freeradius无法在启动时启动
• Docker / CoreOS上的Galera群集（MariaDB）：第一次尝试时第二个节点不起作用
• 工作Nginx fastcgi_cache php-fpmcaching和静态文件cachingconfiguration？
• MariaDB集群与MySQL的Percona集群

我有一些设置为SST使用xtrabackup，iptables防火墙等，但为了尝试find问题，我把一切都closures，并与最简单的configuration和仍然是相同的结果。

这是my.cnf

我也意识到xtrabackup需要访问权限，所以我也从远程服务器为该用户创build了一个GRANT条目，并通过手动login进行testing，仍然没有骰子。

有任何想法吗？
