Apache Flink部署模式有好几种，本文主要介绍Apache Flink的本地部署模式。
本地部署模式主要用于开发者程序调试测试使用。
先决条件
- 运行系统：系统方面没有过多要求，Linux、Mac、Windows均可
- Java 1.8.x以上，Apache Flink不支持1.8.x以下的版本。
检查系统的Java版本
$ java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
下载、启动Flink
下载
进入Apache Flink官网下载安装包。下载地址：https://flink.apache.org/downloads.html
我们下载Apache Flink的最新包1.6.2版本
wget http://mirror.metrocast.net/apache/flink/flink-1.6.2/flink-1.6.2-bin-scala_2.11.tgz

配置环境变量
在~/.bash_profile文件中添加以下变量：
export $FLINK_HOME=/opt/flink-1.6.2
export $PATH = $PATH:$FLINK_HOME/bin
启动Flink
$ $FLINK_HOME/bin/start-cluster.sh # Start Flink
通过web前端检查服务是否正常运行
http://localhost:8081
Web前端可以看到有一个可用的TaskManager实例。
通过jps检查服务启动情况
$ jps
4705 TaskManagerRunner
4940 Jps
4286 StandaloneSessionClusterEntrypoint
还可以通过检查logs目录中的日志文件来验证系统是否正在运行：
flink-1.6.2 tail log/flink-*-standalonesession-*.log

运行example
首先，我们使用netcat来启动本地服务器
$ nc -l 9000
提交Flink工程
$ ./bin/flink run examples/streaming/SocketWindowWordCount.jar --port 9000
Starting execution of program
程序连接到socket端口并等待输入。 可以检查Web界面以验证作业是否按预期运行：
检查jps,多了一个CliFrontend进程。
4705 TaskManagerRunner
5330 Jps
5052 CliFrontend
4286 StandaloneSessionClusterEntrypoint
####单词在5秒的时间窗口中计算（处理时间，翻滚窗口）并打印到标准输出。 监视TaskManager的输出文件并在nc中写入一些文本（输入在点击后逐行发送到Flink）：
$ nc -l 9000
lorem ipsum
ipsum ipsum ipsum
bye
.out文件会在每个时间窗口的末尾打印计数
$ tail -f log/flink-*-taskexecutor-*.out
lorem : 1
bye : 1
ipsum : 4
停止Flink服务
$ ./bin/stop-cluster.sh
