ES系列2、CentOS7安裝ES head6.3.1

1.Head插件簡介

ElasticSearch-head是一個H5編寫的ElasticSearch集羣操做和管理工具，能夠對集羣進行傻瓜式操做。

• 顯示集羣的拓撲,而且可以執行索引和節點級別操做
• 搜索接口可以查詢集羣中原始json或表格格式的檢索數據
• 可以快速訪問並顯示集羣的狀態
• 有一個輸入窗口,容許任意調用RESTful API。這個接口包含幾個選項,能夠組合在一塊兒以產生有趣的結果;
• 5.0版本以前能夠經過plugin名安裝，5.0以後能夠獨立運行。

2.Head插件安裝

2.1安裝NodeJS

[root@node1 ~]# yum install -y nodejs

3.安裝head

3.1下載head插件源碼

3.2下載依賴 

    進入elasticsearch-head-master目錄，執行下面命令：

[es@node1 elasticsearch-head-master]$ npm install > phantomjs-prebuilt@2.1.16 install /home/es/elasticsearch-head-master/node_modules/phantomjs-prebuilt > node install.js PhantomJS not found on PATH Download already available at /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2 Verified checksum of previously downloaded file Extracting tar contents (via spawned process) Removing /home/es/elasticsearch-head-master/node_modules/phantomjs-prebuilt/lib/phantom Copying extracted folder /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2-extract-1515165531727/phantomjs-2.1.1-linux-x86_64 -> /home/es/elasticsearch-head-master/node_modules/phantomjs-prebuilt/lib/phantom Writing location.js file Done.

若是上面命令安裝較慢或失敗，能夠嘗試國內鏡像安裝

[es@node1 elasticsearch-head-master]$ sudo npm install -g cnpm --registry=https://registry.npm.taobao.org [sudo] password for es: /usr/bin/cnpm -> /usr/lib/node_modules/cnpm/bin/cnpm /usr/lib └─┬ cnpm@5.1.1 ├─┬ npminstall@3.3.0 │ ├── binary-mirror-config@1.7.3 │ ├── moment@2.20.1 │ └─┬ tar@4.2.0 │ └── minizlib@1.1.0 └─┬ urllib@2.25.3 └─┬ proxy-agent@2.1.0 └─┬ pac-proxy-agent@2.0.0 └─┬ socks-proxy-agent@3.0.1 └─┬ agent-base@4.1.2 └─┬ es6-promisify@5.0.0 └── es6-promise@4.2.2 [es@node1 elasticsearch-head-master]$ cnpm install ⠸ [6/10] Installing json-schema-traverse@^0.3.0platform unsupported karma@1.3.0 › chokidar@1.7.0 › fsevents@^1.0.0 Package require os(darwin) not compatible with your platform(linux) [fsevents@^1.0.0] optional install error: Package require os(darwin) not compatible with your platform(linux) ✔ Installed 10 packages ✔ Linked 313 latest versions PhantomJS not found on PATH Download already available at /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2 Verified checksum of previously downloaded file Extracting tar contents (via spawned process) Removing /home/es/elasticsearch-head-master/node_modules/_phantomjs-prebuilt@2.1.16@phantomjs-prebuilt/lib/phantom Copying extracted folder /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2-extract-1515223629881/phantomjs-2.1.1-linux-x86_64 -> /home/es/elasticsearch-head-master/node_modules/_phantomjs-prebuilt@2.1.16@phantomjs-prebuilt/lib/phantom Writing location.js file Done.

4.配置

4.1中止ElasticSearch

若是ElasticSearch已經啓動，須要先中止

[es@node1 ~]$ jps 3261 Elasticsearch 3375 Jps [es@node1 ~]$ kill 3261

4.2配置 ElasticSearch，使得HTTP對外提供服務

[es@node1 elasticsearch-6.1.1]$ vi config/elasticsearch.yml

添加以下內容

# 增長新的參數，這樣head插件能夠訪問es。設置參數的時候:後面要有空格 http.cors.enabled: true http.cors.allow-origin: "*"

4.3 修改Head插件配置文件

[es@node1 elasticsearch-head-master]$ vi Gruntfile.js

找到connect：server，添加hostname一項，以下

connect: { server: { options: { hostname: '0.0.0.0', port: 9100, base: '.', keepalive: true } } }

5.啓動

5.1啓動elasticsearch

首先確認elasticsearch已經啓動

[es@node1 elasticsearch-6.1.1]$ bin/elasticsearch -d [es@node1 elasticsearch-6.1.1]$ jps 3451 Jps 3436 Elasticsearch [es@node1 elasticsearch-6.1.1]$

5.2啓動head

經過命令grunt server啓動head

[es@node1 elasticsearch-head-master]$ grunt server Running "connect:server" (connect) task Waiting forever... Started connect web server on http://node1:9100

或者經過命令npm run start也能夠啓動head

[es@node1 elasticsearch-head-master]$ npm run start > elasticsearch-head@0.0.0 start /home/es/elasticsearch-head-master > grunt server Running "connect:server" (connect) task Waiting forever... Started connect web server on http://node1:9100

5.3訪問9100端口

http://node1:9100/

若是出現「未鏈接」，請修改localhost爲node1，而後單擊「鏈接」按鈕

6 簡單應用

  6.1建立索引

[root@node1 ~]# curl -XPUT node1:9200/test {"acknowledged":true,"shards_acknowledged":true,"index":"test"}[root@node1 ~]# 

  6.2查看head變化
