在elasticsearch-head源碼目錄中，執行npm install：
1 npm install
在運行npm install時，可能會存在Head插件phantomjs權限問題：
1 [root@localhost elasticsearch-head]# npm install 2 phantomjs-prebuilt@2.1.16 install /usr/local/elasticsearch-head/node_modules/phantomjs-prebuilt 3 node install.js 4 PhantomJS not found on PATH 5 Download already available at /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2 6 Verified checksum of previously downloaded file 7 Extracting tar contents (via spawned process) 8 Removing /usr/local/elasticsearch-head/node_modules/phantomjs-prebuilt/lib/phantom 9 Copying extracted folder /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2-extract-1513568757772/phantomjs-2.1.1-linux-x86_64 -> /usr/local/elasticsearch-head/node_modules/phantomjs-prebuilt/lib/phantom 10 Phantom installation failed { Error: EACCES: permission denied, link '/tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2-extract-1513568757772/phantomjs-2.1.1-linux-x86_64' -> '/usr/local/elasticsearch-head/node_modules/phantomjs-prebuilt/lib/phantom' 11 errno: -13, 12 code: 'EACCES', 13 syscall: 'link', 14 path: '/tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2-extract-1513568757772/phantomjs-2.1.1-linux-x86_64', 15 dest: '/usr/local/elasticsearch-head/node_modules/phantomjs-prebuilt/lib/phantom' } Error: EACCES: permission denied, link '/tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2-extract-1513568757772/phantomjs-2.1.1-linux-x86_64' -> '/usr/local/elasticsearch-head/node_modules/phantomjs-prebuilt/lib/phantom' 16 npm WARN elasticsearch-head@0.0.0 license should be a valid SPDX license expression 17 npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modules/fsevents): 18 npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"}) 19 20 npm ERR! code ELIFECYCLE 21 npm ERR! errno 1 22 npm ERR! phantomjs-prebuilt@2.1.16 install: `node install.js` 23 npm ERR!

解決方法,在npm install命令後加 -g 參數：
1 npm install -g
最後，在elasticsearch-head源代碼目錄下啓動nodejs，運行 grunt server。
運行成功後，訪問 http://localhost:9100 網站，即可看到elasticsearch的相關信息：
