Neo4j群集无法启动

标签： neo4j

我正在构建一个Neo4j HA群集并按照https://neo4j.com/docs/operations-manual/current/tutorial/highly-available-cluster/

中的步骤进行操作

我有3台机器在单实例Docker容器中运行Neo4j。

Neo4j在每台机器上作为独立服务器运行良好，但是当我添加HA配置时，它无法启动。

每台计算机都是使用相同的预建映像创建的，因此它们的配置相同，但ha.server_id除外，它对每台计算机都是唯一的（值为1,2,3）。

防火墙关闭，我已经验证了这些机器之间的连接。

Neo4j HA配置为：

ha.server_id=1
ha.initial_hosts=172.0.30.110:5001,172.0.31.39:5001,172.0.32.249:5001
dbms.mode=HA

要启动Neo4j，我在每台机器上运行以下命令：

/usr/bin/docker run \
--publish=7474:7474 --publish=7687:7687 --publish=5001:5001 \
--volume=/var/lib/neo4j/data:/data \
--volume=/var/lib/neo4j/logs:/logs \
--volume=/var/lib/neo4j/conf:/conf \
--name=neo4j \
neo4j:3.0-enterprise

当我在机器2和3上运行启动命令时，有时在机器1上运行启动命令时，在“尝试加入群集”后出现错误。偶尔（但不是所有时间）当我在机器1上运行命令时，它意识到它是第一台机器并继续初始化为主机。

以下是完整的失败和成功消息。我无法弄清楚为什么只有一台机器（顺便说一下第一台机器）正在做它应该做的事情而不是所有时间。我还需要弄清楚如何让其他两台机器在集​​群中注册。

  1. 为什么一个节点有时会使用群集启动Neo4j，有时不会？
  2. 为什么第二和第三个节点没有注册到群集？
  3. 我应该在哪看？

    4. 错误（在所有3台机器上都可见）：
