一.Flink下载
本次以Flink 1.9.0版本为例。
下载 flink-1.9.0-bin-scala_2.12.tgz
下载后解压到 D:\flink\flink-1.9.0 目录
如果需要其他版本，可以在如下链接下载:
https://archive.apache.org/dist/flink/
二.运行Flink
2.1 Java安装
运行 Flink 需要安装 Java 7.x 或更高的版本，操作系统需要 Win 7 或更高版本。
C:\Users\Administrator>cd \
C:\>java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)
C:\>
如上图所示，则表示Java安装成功，如未安装Java可参考如下博客
Java安装
2.2 运行Flink
运行Flink的命令非常简单，只需要进入到解压目录的bin目录下，运行start-cluster.bat即可
C:\>D:
D:\>cd D:\flink\flink-1.9.0\bin
D:\flink\flink-1.9.0\bin>start-cluster.bat
Starting a local cluster with one JobManager process and one TaskManager process.
You can terminate the processes via CTRL-C in the spawned shell windows.
Web interface by default on http://localhost:8081/.
D:\flink\flink-1.9.0\bin>
三.访问 Flink UI
Flink有个UI界面，可以用于监控Flilnk的job运行状态，上一步已经给出了具体链接
http://localhost:8081/
四.运行自带的 WordCount 示例
以统计 Flink 自带的 README.txt 文件为例。
命令:
D:
cd D:\flink\flink-1.9.0\bin
flink.bat run D:\flink\flink-1.9.0\examples\batch\WordCount.jar -input D:\flink\flink-1.9.0\README.txt -output D:\flink\flink-1.9.0\README_CountWord_Result.txt
运行记录:
C:\Users\Administrator>cd \
C:\>D:
D:\>cd D:\flink\flink-1.9.0\bin
D:\flink\flink-1.9.0\bin>
D:\flink\flink-1.9.0\bin>flink.bat run D:\flink\flink-1.9.0\examples\batch\WordCount.jar -input D:\flink\flink-1.9.0\README.txt -output D:\f
link\flink-1.9.0\README_CountWord_Result.txt

UI管理界面可以看到刚刚运行的FLink程序(之前运行失败了一个，所以是两个)
