CentOS VM上的MariaDB群集无法正常工作

标签： centos cluster-computing mariadb galera

我过去在CentOS 6.3虚拟机上成功配置了MariaDB-Galera集群。突然之间的事情就是不起作用。这似乎是从MariaDB-Galera-server.x86_64版本5.5.37-1.el6开始的问题。我最后一次记得这个工作是5.5.36版。设置有什么变化吗？

我在CentOS 6.3和6.5上尝试过这种方法但没有成功。

行。我尝试了一些不同的东西，最后回到使用以前的版本。 5.5.36和5.5.37之间发生了一些变化，导致数据文件传输到新节点失败。

我正在使用rsync的SST方法。

我的测试环境包含Macbook上的三个CentOS 6.5虚拟机。我使用yum来安装MariaDB和Galera。唯一的区别在于MariaDB.repo文件。有效的安装使用： baseurl = http://yum.mariadb.org/5.5.36/centos6-amd64

不起作用的安装使用： baseurl = http://yum.mariadb.org/5.5/centos6-amd64

其他一切都是一样的。

当我启动第二个节点时，主节点上的日志文件包含以下内容：

我不确定这一切是如何适合的。
