分布式模式下将orientdb从2.1.15升级到2.2.28

Question

我正在尝试在分布式设置中将 orientdb 版本从 2.1.15 升级到 2.2.28：node1 (MASTER) 和 node2 (MASTER)。

升级过程： 1.停止node1和node上的orientdb服务 2.升级node1 2.1 将现有数据库复制到 ~/tmp 文件夹中。 2.2 下载 Orientdb v2.2.28 复制现有 Orientdb 文件夹中的所有文件。 2.3 将现有数据库从 ~/tmp 复制到 orientdb 工作目录。 2.4 将node1作为独立服务器运行（不是分布式模式） 2.5 停止节点1 2.6 配置node1分布式运行，node 1分布式运行 3.按照与node1相同的步骤升级node2

文件修改为以分布式模式运行

hazelcast.xml

<network>
   <port auto-increment="false">3000</port>
   <join>
      <multicast enabled="false">
         <multicast-group>235.1.1.1</multicast-group>
         <multicast-port>2434</multicast-port>
      </multicast>
      <tcp-ip enabled="true">
         <member>node1:3000</member>
         <member>node2:3000</member>
      </tcp-ip>
   </join>
</network>

default-distributed-db-config.json

{
  "autoDeploy": true,
  "readQuorum": 1,
  "writeQuorum": "majority",
  "executionMode": "undefined",
  "readYourWrites": true,
  "newNodeStrategy": "static",
  "servers": {
    "*": "master"
  },
  "clusters": {
    "internal": {
    },
    "*": {
      "servers": ["node1","node2"]
    }
  }
}

但是我收到一个错误 node2 在 node1 之后加入集群

这是升级以分布式模式运行的orientdb的正确方法吗？或者这与构建的 2.2.28 相关（如果我使用相同的升级过程从 2.2.28 降级到 2.2.15，它会再次开始工作）。

如果有人能指出我正确的方向，那就太好了。

Answer 1

所以你需要先解决这个问题。节点应该能够在配置的 IP/DNS、端口等上看到彼此（或相互 ping 通）。如果无法访问 3000，请尝试其他端口。
