elasticsearch elasticsearch中的状态503

运行elasticsearch时，我得到状态503错误。直到昨天它还工作得很好，现在我突然发现了这个错误

{
 status: 503,
 name: "My First Node",
 cluster_name: "Mycluster1",
 version: {
   number: "1.7.2",
   build_hash: "e43676b1385b8125d647f593f7202acbd816e8ec",
   build_timestamp: "2015-09-14T09:49:53Z",
   build_snapshot: false,
   lucene_version: "4.10.4"
 },
tagline: "You Know, for Search"
}

我尝试在配置文件中添加这一行，但没有带来任何更改

discovery.zen.ping.multicast.enabled: false

我还重新启动了elasticsearch，但即使这样也没有解决我的问题

任何帮助都将不胜感激

elasticsearch日志文件中有什么吗？@keety:我找不到elasticsearch.log文件。在elasticsearch文件夹中，我只有3个文件elasticsearch.yml、elasticsearch.yml.dpkg-old和logging.yml

elasticsearch.yml

应该引用日志目录。默认情况下，日志路径为@keety：我已从日志文件中添加了错误消息。我看到的主要错误是“无已知主节点”.elasticsearch日志文件中有什么吗？@keety:我找不到elasticsearch.log文件。在elasticsearch文件夹中，我只有3个文件elasticsearch.yml、elasticsearch.yml.dpkg-old和logging.yml
