    Mariadb 10.1 galera cluster 集群joiner 节点加入集群 会出现这种报错,导致mysql一直点点点,这里我贴出报错。2016年04月19日13:34:58

    如果细心的人,肯定会发现数据目录下有一个保存UUID的文件grastate.date 里面会保存本地mariadb的UUID。博主尝试更改里面的UUID 改成集群的UUID 就可以启动,但是这样会导致很多表的错误。所以没有继续研究下去

    还有一种是让它一直点点点下去,这个过程看官方文档,也没有解释的那么详细,是和新节点的4568端口通信,然后我吃完饭回来,大概间隔20min 就同步成功了,就起来了- -!。

    还有一种方法是同事说,让joiner 节点指定同步一个index=0的集群节点,就可以加入。

    mariadb10.1交流很少,有交流的同学可以在本博文留言。
