bin目录执行安装

F:\ELK\elasticsearch-2.4.1\bin>service install
Installing service      :  "elasticsearch-service-x64"
Using JAVA_HOME (64-bit):  "F:\java\jdk8"
The service 'elasticsearch-service-x64' has been installed.

安装成功，如果启动失败（进logs目录，查看错误信息）

[error] [ 6376] Failed creating java %JAVA_HOME%\jre\bin\server\jvm.dll
 [error] [ 6376] 系统找不到指定的路径。

直接利用管理服务

 #运行 service manager 会弹出服务管理界面 修改jvm指定路径
F:\ELK\elasticsearch-2.4.1\bin>service manager

debian8

sudo dpkg -i  elasticsearch-2.4.2.deb
bin$> ./elasticsearch   #启动提示没有权限

需要授权执行命令 chmod +x bin/elasticsearch
再次执行 ./elasticsearch -d 即可后台启动
使用 ps aux|grep elasticsearch 可以查看是否启动

设置开机启动
创建脚本 start.sh

#!bin/bash
export JAVA_HOME=/usr/bin/java
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
 #切换到cs用户（带环境变量）
su -cs<<!
cd /opt/elasticsearch/bin
./elasticsearch &
exit
!

修改启动文件 mousepad /etc/init.d/elasticsearch

#!bin/bash
