尝试使用以下命令在 RHEL 6 上将两个 MariaDB Galera 服务器集群在一起时：
mysqld -uroot --wsrep_cluster_address=gcomm://
然后屏幕就停在那里，向我输出以下输出：
130805 10:26:50 InnoDB: The InnoDB memory heap is disabled

据我所知，它似乎正在工作。然后我发出命令来连接到这个集群主服务器：
$ mysqld -uroot --wsrep_cluster_address=gcom://mariadbclstr02.local.net

现在它们都只是坐在那里，据我所知什么都没有发生。有没有办法看看他们是否做得正确？我正在关注 MariaDB 网站上的文档：https://kb.askmonty.org/en/getting-started-with-mariadb-galera-cluster/。我还可以使用 netcat 连接到两个服务器，nc -vz mariadbclstr02.local.net 3306并且nc -vz mariadbclstr01.local.net 3306
答案1
据我发现，我不必像以前那样发出命令，而是必须编辑/etc/my.cnf并添加这些行。相反，我创建了一个/etc/my.cnf.d/zabbix_cluster.cnf文件，并将指定的行放在https://kb.askmonty.org/en/getting-started-with-mariadb-galera-cluster/。然后我就可以正常启动 MySQL 了。然后编辑/etc/my.cnf/zabbix_cluster.cnf配置文件后，我必须通过发出以下命令来启动集群/etc/init.d/mysql start --wsrep_cluster_address=gcomm://，然后初始化一个新集群并允许其他人加入。
