Question

好的，所以我正在使用此仓库的修订版：https://github.com/CaptTofu/mysql_replication_kubernetes/tree/master/galera_sync_replication

修改后的文件是：

服务：

SELECT
*
FROM
  `wehco-bi.64884663.ga_sessions_20180928` AS GA, UNNEST(hits) AS hits
  <br/>LEFT JOIN `wehco-bi.BlueConic.ao` AS BC
  <br/>ON GA.customDimensions.index.3 = BC.bc_profile_id
<br/>LIMIT 100

pxc1，其相同的复制控制器，用于2和3的发现和持久卷声明服务，只是更改了数字

apiVersion: v1
kind: Service

  name:  ro-db


  labels:
    unit: pxc-cluster
spec:
  ports:
    - port: 3306
      name: mysql
  selector:
    unit: pxc-cluster

几天前它正在运行，并且进行了很多测试，测试了Pod，节点的运行情况，并查看了复制投票的工作方式以及所有工作情况，现在，当我集成到应用程序时，它就不会启动，我不明白为什么它的配置仍然有效，为什么我在Internet，SO，GitHub上查看了很多内容，并尝试了建议的修复程序，但无法正常工作。
