我在 linux 机器上安装了 3 个 neo4j 版本 1.9.4 的实例，位于 3 个不同的目录中：Neo4j01, neo4j02, neo4j03.
我已经更新了配置文件neo4j.properties，并在链接（ http://docs.neo4j.org/chunked/milestone/ha-setup-tutorial.html）neo4j-server.properties中提到。
当我一个接一个地启动所有neo4j实例时，它们已成功安装，但一段时间后，3个neo4j进程/实例中的2个自动消失。我通过ps -aef | grep neo4j.
当我检查控制台日志时，我发现以下错误：

现在，只有neo4j01进程正在运行，neo4j02并且neo4j03进程消失了。但即使neo4j01进程启动并运行，我也无法访问http://htname:7474/webadmin/#/info/org.neo4j/High%20Availability/.
拜托，有人可以对此有所了解吗？
