Question

谢谢！我真的想在3台服务器上安装。出于举个例子的目的，我是试图设置一个类“actor”，有3个集群“actor_server74”， “actor_server75”和“actor_server76”。我的服务器叫做server74，server75和 server76。我希望这些集群的排列方式使得每个集群都有2个副本如果1个节点出现故障，我仍然可以访问所有数据，所以对于例如：

server74是actor_server74的主人，并且有一个actor_server75的副本。
server75是actor_server75的主人，并且有一个actor_server76的副本。
server76是actor_server76的主人，并且有一个actor_server74的副本。

我已尝试使用以下步骤进行设置： 1.下载OrientDB 2.1.15社区并解压缩到3台服务器上。 2.从每台服务器上的databases目录中删除GratefulDeadConcerts数据库。 3.使用tcp-ip而不是multi-cast配置hazelcast.xml并指定3台服务器的IP地址。

        <join>
            <multicast enabled="false">
                <multicast-group>224.0.0.1</multicast-group>
                <multicast-port>2434</multicast-port>
            </multicast>
            <tcp-ip enabled="true">
                <member>172.21.0.74:2434</member>
                <member>172.21.0.75:2434</member>
                <member>172.21.0.76:2434</member>
            </tcp-ip>
        </join>
    </network>
    <executor-service>
        <pool-size>16</pool-size>
    </executor-service>
</hazelcast>

在server74上编辑default-distributed-db-config.json，如下所示： enter image description here
使用dserver.sh启动server74。
使用server74上的控制台创建数据库： connect remote：localhost root root create database remote：localhost / testdb root root plocal graph
创建一个类并重命名默认群集：创建类actor扩展v alter cluster actor name actor_server74
shutdown server74 with shutdown.sh
将orientdb-community-2.1.15从server74复制到server75和server76，并更新config / orientdb-server-config.xml，server75中的nodeName，如下所示：
使用dserver.sh启动server74

11。使用dserver.sh启动server75，抛出异常如下。
