NoteBook学习（二）-------- Zeppelin简介与安装

Zeppelin官网地址：

http://zeppelin.apache.org/

Github地址：

（参照官网）

1、什么是zeppelin

　　多用途的笔记本。数据的采集  发现 分析  可视化 协作。。 支持20+种后端语言，支持多种解释器  内置集成Spark

2、安装

　　这里安装zeppelin0.8.0

Name	Value
Oracle JDK	1.7  (set JAVA_HOME)
OS	Mac OSX  Ubuntu 14.X  CentOS 6.X  Windows 7 Pro SP1

需要环境：JDK 7 以上     centos6以上

　　下载完整包，下载地址：

　　http://www.apache.org/dyn/closer.cgi/zeppelin/zeppelin-0.8.0/zeppelin-0.8.0-bin-all.tgz

　　下载完成后，上传centos服务器    解压：

　　tar -zxvf zeppelin-0.8.0-bin-all.tgz

　　在目录下启动，注意默认端口是8080：

　　bin/zeppelin-daemon.sh start

　　停止进程  zeppelin-daemon.sh stop

　　注意此时配置没有修改，用的都是默认的   java_home   xmx   xms   ...

　　　启动成功后，浏览器访问：localhost:8080

　　　就能看到UI页面

   bin/zeppelin-daemon.sh stop 停止进程
也可以注册成服务

配置ssl需要更多的配置

4 Zeppelin UI

登录到localhost：8080后，就可以看到UI页面
可以参照官方文档学习相关操作：
https://zeppelin.apache.org/docs/latest/quickstart/explore_ui.html

　左侧   import note  可以导入笔记本

create note 是创建笔记本  也可以看到之前的笔记本  他们默认保存在$ZEPPELIN_HOME/notebook下

右上角可以设置shiro配置   配置信息  凭证  解释器  解释器可以编辑  比如spark的路径

创建好后进入编辑页面，可以编写代码 ，执行。
