Ubuntu 15.10 elasticsearch 2.3无法连接到本地主机端口9200:连接被拒绝

我刚刚在OSX El Capitan和Ubuntu 15.10上安装了相同版本的elasticsearch 2.3。命令

curl-XGET'http://localhost:9200/“

在OSX中工作得很好，但在Ubuntu 15.10中，我遇到了以下错误：

root@levilinode:~# curl -XGET 'http://localhost:9200/'
curl: (7) Failed to connect to localhost port 9200: Connection refused

使用与Linux有关的所有帖子，在文件

/etc/elasticsearch/elasticsearch.yml

中设置参数

network.bind\u host

和/或

network.host

到

0.0.0

或

127.0.0.1

的任何尝试都没有成功

我怎样才能让它工作

使用以下指南进行了新安装：

我唯一更改的是将版本从

1.7.2

更新为

2.3.1

现在一切正常。详情如下:

你确定橡皮筋在跑吗？

sudonetstat-tulpn | grep9200

提供了什么输出？你是怎么安装的？如果使用apt，您可能需要使用elastic正在运行的sudo systemctl start elasticsearch手动启动它，以下是证明：root@levilinode：~#服务弹性搜索状态● elasticsearch.service-LSB:启动elasticsearch加载：加载（/etc/init.d/elasticsearch）活动：活动（退出）自2016年4月13日星期三起13:22:46美国东部夏令时；43分钟前文档：man:systemd sysv generator（8）Apr 13:22:46 Levinode systemd[1]：启动LSB:启动elasticsearch。。。4月13日13:22:46 LevilNode systemd[1]：Started LSB:启动elasticsearch。命令sudo netstat-tulpn | grep 9200不返回任何内容。我用所需的详细信息编辑了问题。

Active:Active（exited）

来自服务输出意味着elasticsearch崩溃。检查日志（可能是/var/log/syslog）以了解可能出错的提示。
