Question

我正在使用Ubuntu 16.04并从https://www.elastic.co/guide/en/elasticsearch/reference/5.2/deb.html安装弹性搜索，现在启动它后不会导致任何日志是否开始。然后我输入了命令sudo service elasticsearch status

● elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendo
   Active: failed (Result: exit-code) since Mon 2017-02-20 12:56:37 IST; 2s ago

我在stackoverflow上尝试了一些解决方案，包括这个sudo chown -R elasticsearch:elasticsearch /var/lib/elasticsearch/，甚至尝试重新启动服务，但没有任何效果。即使此修复https://github.com/elastic/elasticsearch/issues/10671也无效。

有关如何解决此问题的任何建议？

Answer 1

我认为你没有安装/识别java。试试这个来安装Oracle的java：

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update && sudo apt-get install oracle-java8-installer

试验：

java -version

然后运行ES服务：

sudo service elasticsearch start

现在一切都应该有效

Answer 2

根据this，尝试设置

在/ etc / default / elasticsearch中将START_DAEMON设置为true

这对我有用。

Answer 3

我遇到了类似的问题，就我而言，我已经在Ubuntu上安装了弹性搜索7.5.1版，并最终成功安装并运行。

Elasticsearch不会在Ubuntu 16.04上启动？
