無法將Elasticsearch作為服務啟動

Question

我正在嘗試在Ubuntu（12.04）計算機上將Elasticsearch（0.90.5）安裝為服務。

我試過了

wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.90.5.deb
sudo dpkg -i elasticsearch-0.90.5.deb

它給出了響應

Selecting previously unselected package elasticsearch.
(Reading database ... 51009 files and directories currently installed.)
Unpacking elasticsearch (from elasticsearch-0.90.5.deb) ...
Setting up elasticsearch (0.90.5) ...
Adding system user `elasticsearch' (UID 107) ...
Adding new user `elasticsearch' (UID 107) with group `elasticsearch' ...
Not creating home directory `/usr/share/elasticsearch'.
* Starting ElasticSearch Server                                               [ OK ] 
Processing triggers for ureadahead ...

然后開始服務

 sudo service elasticsearch start
* Starting ElasticSearch Server                                               [ OK ]

之后，當我檢查狀態時，它顯示

sudo service elasticsearch status
* elasticsearch is not running

我檢查了我的日志，但是它是空的。

9200端口上沒有其他進程在運行

我的Java版本：“ 1.6.0_31”

有誰知道為什么會這樣嗎？

提前謝謝你的幫助

Answer 1

我認為您應該嘗試減少內存。 進行以下更改：

1. vi /opt/elasticsearch-1.3.4/bin/service/elasticsearch.conf
2. 您需要減少內存（ ES_HEAP_SIZE ）限制。 [1024至512等]
3. 保存文件。
4. service elasticsearch start

希望它能解決問題。

我剛剛更新了用於將Elasticsearch作為服務運行的腳本（/etc/init.d/elasticsearch）。 以下腳本解決了該問題。

#! /bin/sh
### BEGIN INIT INFO
# Provides:          elasticsearch
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Starts elasticsearch
# Description:       Starts elasticsearch using start-stop-daemon
### END INIT INFO

then

    then

    else

    fi
