Flink基础系列3-windows安装Flink

• 一.Flink下载
• 二.运行Flink
• • 2.1 Java安装
  • 2.2 运行Flink
• 三.访问 Flink UI
• 四.运行自带的 WordCount 示例
• 参考:

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:flinkflink-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/

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:UsersAdministrator>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

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:flinkflink-1.9.0bin

D:flinkflink-1.9.0bin>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:flinkflink-1.9.0bin>

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/

以统计 Flink 自带的 README.txt 文件为例。

命令:

D:
cd D:flinkflink-1.9.0bin
flink.bat run D:flinkflink-1.9.0examplesbatchWordCount.jar -input D:flinkflink-1.9.0README.txt -output D:flinkflink-1.9.0README_CountWord_Result.txt

运行记录:

C:UsersAdministrator>cd 

C:>D:

D:>cd D:flinkflink-1.9.0bin

D:flinkflink-1.9.0bin>
D:flinkflink-1.9.0bin>flink.bat run D:flinkflink-1.9.0examplesbatchWordCount.jar -input D:flinkflink-1.9.0README.txt -output D:f

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)
