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
