Question

我在linux机器上安装了3个neo4j版本1.9.4的实例，分别位于3个不同的目录中：Neo4j01，neo4j02，neo4j03。

我更新了配置文件neo4j.properties和neo4j-server.properties，如链接（http://docs.neo4j.org/chunked/milestone/ha-setup-tutorial.html）中所述。

当我一个接一个地启动所有neo4j实例时，它们都成功安装，但是经过一段时间后，3个neo4j进程/实例中的2个会自动消失。我通过ps -aef | grep neo4j注意到了它。

当我查看控制台日志时，我发现以下错误：

现在，只有neo4j01进程正在运行，neo4j02和neo4j03进程已消失。但即使neo4j01进程已启动并正在运行，我也无法访问http://htname:7474/webadmin/#/info/org.neo4j/High%20Availability/处的webadmin页面。

拜托，有人可以对此有所了解吗？

您可能需要查看https://github.com/neo-technology/neo4j-enterprise-local-qa。它包含一个rakefile，可以自动完成3个实例的本地设置。在本地克隆回购，并使用

rake setup_cluster start_cluster

将本地运行的群集联机。关机可以通过

完成

rake stop_cluster

在machine[ABC]/conf/中找到配置。

无法为Neo4j高可用性加载webadmin
