一、Knox简介
Announcing Apache Knox 1.6.1!
REST API and Application Gateway for the Apache Hadoop Ecosystem
The Apache Knox™ Gateway is an Application Gateway for interacting with the REST APIs and UIs
of Apache Hadoop deployments.
The Knox Gateway provides a single access point for all REST and HTTP interactions with Apache Hadoop
clusters.Knox delivers three groups of user facing services:
官网介绍：
Apache Knox网关是一个为集群中的Apache Hadoop服务提供单点身份验证和访问的系统。目标是为用户（即访问集群数据和执行作业的用户）和操作员（即控制访问和管理集群的用户）简化Hadoop安全。网关作为服务器（或服务器集群）运行，提供对一个或多个Hadoop集群的集中访问。一般来说，网关的目标如下：
- 为Hadoop REST API提供外围安全，使Hadoop安全更易于设置和使用
- 在外围提供身份验证和令牌验证
- 实现与企业和云身份管理系统的身份验证集成
- 在外围提供服务级别授权
- 公开聚合Hadoop集群的REST API的单个URL层次结构
- 限制访问Hadoop集群所需的网络端点（以及防火墙漏洞）
- 对潜在攻击者隐藏内部Hadoop群集拓扑

一、下载Knox
- 下载地址：下载Knox链接
二、安装Hadoop和Knox
- Hadoop安装可参考博文：Hadoop2.7.3全分布式环境搭建
- 安装Knox
- 注意：需要使用普通用户安装，如omm
- 新建用户组和用户，如:
groupadd knoxgroup useradd -g knoxgroup omm passwd omm
- 新建用户组和用户，如:
- 可参考官网:Quick Start
- 使用omm用户登录服务器，默认安装在/home/omm下
- 上传knox1.6.1.zip包到虚拟机中
- 解压安装：
unzip knox1.6.1.zip - 环境配置（可选）
- 启动LDAP，进入到解压之后的目录/home/omm/knox1.6.1下执行命令：
bin/ldap.sh start - 创建Master密钥,执行如下命令：
bin/knoxcli.sh create-master,回车，输入密钥密码 - 启动Knox服务，执行：
bin/gateway.sh start - 检查LDAP和knox服务是否正常启动，执行:
jps，结果如下：
- 注意：需要使用普通用户安装，如omm
三、读写HDFS
-
通过网关gateway在WebHDFS上调用LISTSTATUS操作，命令如下：
-
执行命令：
curl -i -k -u guest:guest-password -X GET 'https://localhost:8443/gateway/sandbox/webhdfs/v1/?op=LISTSTATUS' -
结果如图：

文字结果：

通过网关gateway在上传文件到HDFS上：
-
执行create操作命令：
curl -i -k -u guest:guest-password -X PUT 'https://localhost:8443/gateway/sandbox/webhdfs/v1/tmp/LICENSE?op=CREATE' -
生成结果：

执行上传Put操作上传本地文件word.txt（如没有请自行创建）到HDFS上：
curl -i -k -u guest:guest-password -T /home/omm/word.txt -X PUT 'https://localhost:8443/gateway/sandbox/webhdfs/data/v1/webhdfs/v1/tmp/word?_=AAAACAAAABAAAABwTpIK-W64x8ISPJNY9JvX3XuoTVo-OXwLrz64napWpWGTq-oww25mTd4fgPehTjUXmd2_FKZ37LwpehOpiUBZtO788j4AEKIBv30d6HApTLika55LfTqUIugsgKw_bl6G8jgBfxQa-W2-qiB5xRzijYnrs0NYYveBgVnpS8lKlV1y-RJZFJjrPw' -

通过网关gateway在查看HDFS上的文件：
-
执行open操作，命令：
curl -i -k -u guest:guest-password -X GET 'https://localhost:8443/gateway/sandbox/webhdfs/v1/tmp/LICENSE?op=OPEN'结果：
将

当然可以使用hdfs命令查看/tmp目录下是不是多出了一个/tmp/word的文件，如下所示:
查看下内容：hdfs dfs -cat /tmp/word，结果和上述的结果一样，具体如下所示：
至此，简单的安装测试apache knox就到此结束，该篇博文参考了knox官网教程，在验证过程中记录下来，当作是练习使用吧，希望对你有所帮助~~~
