无法在ubuntu 16.04中将elasticsearch作为服务启动 [英] Can not start elasticsearch as a service in ubuntu 16.04

问题描述

我最近将我的机器从Ubuntu 14.04 升级到 16.04 。我遇到使用 elasticsearch 作为服务的问题。我已安装 elasticsearch 使用：

I have recently upgraded my machine from Ubuntu 14.04 to 16.04. I am facing problem of using the elasticsearch as a service. I installed elasticsearch using:

sudo apt-get install elasticsearch

现在 sudo service elasticsearch status 命令显示我的结果：

Now sudo service elasticsearch status command shows me this result:

elasticsearch.service - LSB: Starts elasticsearch
   Loaded: loaded (/etc/init.d/elasticsearch; bad; vendor preset: enabled)
   Active: active (exited) since Sat 2016-07-30 18:28:13 BDT; 1h 19min ago
     Docs: man:systemd-sysv-generator(8)

   CGroup: /system.slice/elasticsearch.service

Jul 30 19:28:54 dimik systemd[1]: Started A search engine.
Jul 30 19:29:18 dimik systemd[1]: Started LSB: Starts elasticsearch.

虽然我的机器上安装了Java，但我可以使用此命令启动服务器。

Although Java is installed in my machine and I can start the server using this command.

sudo /usr/share/elasticsearch/bin/elasticsearch

我有点被困在这里。任何帮助将不胜感激。

I am kind of stuck here. Any help will be appreciated.

推荐答案

我找到了解决此问题的方法。解决方案来自此讨论主题 - 无法启动elasticsearch弹性网站上的Ubuntu 16.04 。

I found the solution for this issue. The solution comes form this discussion thread- Can’t start elasticsearch with Ubuntu 16.04 on elastic's website.

似乎让Elasticsearch在 16.04上运行您必须在 / etc / default / elasticsearch 上将 START_DAEMON 设置为true。它在默认情况下被注释掉，并且取消注释它使Elasticsearch再次启动就好了。

It seems that to get Elasticsearch to run on 16.04 you have to set START_DAEMON to true on /etc/default/elasticsearch. It comes commented out by default, and uncommenting it makes Elasticsearch start again just fine.

确保使用 systemctl restart 而不只是启动因为
服务是在安装后立即启动的，显然有
一些 socket / pidfile / something systemd 保持必须在能够再次启动服务之前释放
。

Be sure to use systemctl restart instead of just start because the service is started right after installation, and apparently there's some socket/pidfile/something that systemd keeps that must be released before being able to start the service again.
