1.安裝elasticsearch部脚，參考http://www.cnblogs.com/hanyinglong/p/5409003.html就可以了
簡單描述下：
mkdir-p /usr/local/kencery/elasticsearch
groupadd elasticsearch
useradd -d /usr/local/kencery/elasticsearch -g elasticsearch -p elasticsearch elasticsearch
然后將tar包解壓到elasticsearch目錄下就可以了屉凯，我下載的版本是elasticsearch-6.2.4.tar.gz
啟動時直接在bin目錄下執(zhí)行：./elasticsearch
有兩個問題注意下邪媳，一是不要用root用戶執(zhí)行，二是有可能會遇到錯誤：
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
參考https://blog.csdn.net/jiankunking/article/details/65448030修改下/etc/sysctl.conf扩氢，記得改下elasticsearch.yml中的network.host以及端口配置唉堪，重啟后就可以訪問了：http://192.168.141.13:9200/

2.安裝elasticsearch-head，這里敲下黑板减拭，真的很麻煩，如果不了解区丑，花費(fèi)大半天時間也是很正常的拧粪，這里就直接說下最后成功的辦法
2.1?elasticsearch 5.x之后不支持直接plugin安裝head插件，而是將head作為一個獨(dú)立的服務(wù)安裝的沧侥，首先需要安裝依賴的node可霎，npm，grunt宴杀，參考https://blog.csdn.net/hard_boy/article/details/79565068癣朗，我是以root執(zhí)行的，稍微有點(diǎn)不同：
apt-getinstall npm
apt-getinstallnodejs-legacy
npm install-g grunt
npm install-g grunt-cli
下載elasticsearch-head旺罢，我解壓到目錄/usr/local/kencery/elasticsearch-head旷余，將目錄用戶改為elasticsearch
2.2?然后修改配置
2.2.1?修改head的連接地址 elasticsearch-head/_site/app.js
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") ||"http://localhost:9200";
將localhost改為自己的ip
2.2.2?修改服務(wù)器的監(jiān)聽地址elasticsearch-head/Gruntfile.js
connect: {?
? ? ? ? ? ? ? server: {?
? ? ? ? ? ? ? ? ? options: {?
? ? ? ? ? ? ? ? ? ? ? port: 9100,?
? ? ? ? ? ? ? ? ? ? ? base: '.',?
? ? ? ? ? ? ? ? ? ? ? keepalive: true?
? ? ? ? ? ? ? ? ? }?
? ? ? ? ? ? ? }?
? ? ? ? ? }?
options中添加 hostname:?'*'
2.2.3?修改elasticseach的配置文件elasticsearch.yml, 修改對應(yīng)的ip以及跨域的設(shè)置，添加：
http.cors.enabled:?true?
http.cors.allow-origin:?"*"??
2.3?在elasticsearch-head下運(yùn)行: grunt server
2.3.1?但是會出現(xiàn)錯誤提示（當(dāng)時命令敲的npm start扁达，應(yīng)該是一樣的）：
root@ubuntu:/usr/local/kencery/elasticsearch-head# npm start> elasticsearch-head@0.0.0start /usr/local/kencery/elasticsearch-head> grunt server

看提示大概有提到版本不是最新的問題正卧，所以就抱著試一試的心態(tài)去升級npm以及node
參考https://www.cnblogs.com/ae6623/p/6242423.html
npm cache clean -f
npm install-g n
n stable
npm installnpm@latest -g
再查看下版本，會看到
elasticsearch@ubuntu:~$ node -v
v10.4.0elasticsearch@ubuntu:~$ npm -v6.1.0
2.3.2?但是運(yùn)行g(shù)runt server依然報(bào)錯：
grunt hasn't been installed locally to your project
參考https://segmentfault.com/q/1010000004172559/a-1020000004193932跪解，執(zhí)行：
npminstallgrunt --save-dev
2.3.3?再次運(yùn)行炉旷，依然報(bào)錯：
elasticsearch@ubuntu:/usr/local/kencery/elasticsearch-head$ grunt server>> 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.
然后我干脆把有關(guān)grunt的都裝了一遍最新的：
npminstall grunt@latest
npm installgrunt-cli@latest
npm installgrunt-contrib-copy@latest
npm installgrunt-contrib-concat@latest
npm installgrunt-contrib-uglify@latest
npm installgrunt-contrib-clean@latest
npm installgrunt-contrib-watch@latest
npm installgrunt-contrib-connect@latest
npm installgrunt-contrib-jasmine@latest
2.3.4?最后grunt server終于可以啟動了：
elasticsearch@ubuntu:/usr/local/kencery/elasticsearch-head$ grunt server
(node:1527) ExperimentalWarning: The http2 module is an experimental API.
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://localhost:9100
可以看到elasticsearch服務(wù)的端口是9200，head插件服務(wù)的端口是9100惠遏，我們訪問head然后head再訪問的elasticsearch砾跃。
可以新建索引試一下：
狀態(tài)yellow還是有一些問題，并不影響使用节吮，對于ES也只是剛接觸抽高，并沒多少了解，后續(xù)使用過程中遇到問題再作紀(jì)錄透绩。
