无法将节点添加到 Percona XtraDB 集群

在我的例子中，集群中有两个节点，但是当我用来$service mysql bootstrap-pxc启动 XtraDB 集群时，我发现节点没有添加到集群中。我也检查了/var/log/mysql/error.log，但没有发现任何错误。

问题如下：

mysql> show status like 'wsrep%';

有人能帮我解决这个问题或者给我一些关于如何解决这个问题的有用链接吗？

因此您不需要bootstrap-pxc向集群添加节点。这仅适用于您初始化的集群的第一个成员。所有其他成员都使用以下配置来获取有关当前集群成员的信息。

 wsrep_cluster_address

它看起来像

 wsrep_cluster_address = 1.1.1.1,2.2.2.2,3.3.3.3

例如。

如果第三个成员没有这个，那么就把它加进去，然后做正常的

service mysql start

然后它应该尝试加入集群
