安装运行
1、前置安装java8
jdk-8u112-linux-x64.rpm
下载地址:http://www.oracle.com/technetwork/java/javase/downloads/index.html
2、下载
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.1.1.zip
3、解压
unzip elasticsearch-5.1.1.zip
4、运行
./bin/elasticsearch
./bin/elasticsearch -d #后台运行
tail -f logs/elasticsearch.log #查看日志
注:ES有执行脚本的能力,因安全因素,不能在root用户下运行,强行运行会报如下错误:
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root
解决方案:
groupadd es #增加es组
useradd es -g es -p pwd #增加es用户并附加到es组
chown -R es:es elasticsearch-5.1.1 #给目录权限
su es #使用es用户
./bin/elasticsearch -d #后台运行es
外网访问
vi conf/elasticsearch.yml
修改network.host: 0.0.0.0
再次启动linux可能出现如下类似错误
bootstrap checks failed
max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
解决方案
1、vi /etc/sysctl.conf
设置fs.file-max=655350
保存之后sysctl -p使设置生效
2、vi /etc/security/limits.conf 新增
* soft nofile 655350
* hard nofile 655350
3、重新使用SSH登录,再次启动elasticsearch即可。

安装elasticsearch-head插件
elasticsearch 5以后的版本比较新,不支持直接安装head插件,以下是github上提供的安装方法,如下图示
以下为我自己整理的方法,参考来源:http://blog.csdn.net/qq942477618/article/details/53637817
1、下载head插件
wget https://codeload.github.com/mobz/elasticsearch-head/zip/master
2、下载nodejs
nodejs官网下载地址https://nodejs.org/dist/
wget https://nodejs.org/dist/v6.9.2/node-v6.9.2-linux-x64.tar.xz
3、配置node环境变量
xz –d node-v6.9.2-linux-x64.tar.xz
tar –xvf node-v6.9.2-linux-x64.tar
mv node-v6.9.2-linux-x64 /alidata/app/node
vim /etc/profile
export NODE_HOME=/alidata/app/node
export PATH=$PATH:$NODE_HOME/bin
source /etc/profile
# node –v
v6.9.2
# npm –v
3.10.9
4、安装grunt
cd elasticsearch-head-master
npm install -g grunt --registry=https://registry.npm.taobao.org
5、测试一下
cd elasticsearch-head-master
grunt
出现以下提示,为Gruntfile.js引用的,缺少以下包
>> Local Npm module "grunt-contrib-clean" not found. Is it installed?
>> Local Npm module "grunt-contrib-concat" not found. Is it installed?
>> Local Npm module "grunt-contrib-watch" not found. Is it installed?
>> Local Npm module "grunt-contrib-connect" not found. Is it installed?
>> Local Npm module "grunt-contrib-copy" not found. Is it installed?
>> Local Npm module "grunt-contrib-jasmine" not found. Is it installed?
Warning: Task "connect:server" not found. Use --force to continue.
Aborted due to warnings.
安装
npm install grunt-contrib-clean --registry=https://registry.npm.taobao.org
npm install grunt-contrib-concat --registry=https://registry.npm.taobao.org
npm install grunt-contrib-watch --registry=https://registry.npm.taobao.org
npm install grunt-contrib-connect --registry=https://registry.npm.taobao.org
npm install grunt-contrib-copy --registry=https://registry.npm.taobao.org
npm install grunt-contrib-jasmine --registry=https://registry.npm.taobao.org
6、运行
grunt server
7、测试
http://serverip:9100/
修改head目录下的Gruntfile.js配置,head默认监听127.0.0.1
vm Gruntfile.js
hostname: ‘0.0.0.0‘,
8、为es设置跨域访问
vi config/elasticsearch.yml #新增两行
http.cors.enabled: true
http.cors.allow-origin: "*"
9、启动es,启动head插件
