Flink local模式部署

Flink local模式部署

flink的local模式运行在单个jvm中。同时local方便快速测试。

需求：

• Java 1.8.x or higher,
• ssh

1、下载

https://flink.apache.org/downloads.html

2、解压

[root@hadoop01 local]# tar -zxvf /home/flink-1.9.1-bin-scala_2.11.tgz -C /usr/local/
[root@hadoop01 local]# cd ./flink-1.9.1/

3、配置环境变量

export FLINK_HOME=/usr/local/flink-1.9.1/
​
​
export PATH=$PATH:$JAVA_HOME/bin:$ZK_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$KAFKA_HOME/bin:$FLINK_HOME/bin:
​

4、刷新环境变量

[root@hadoop01 flink-1.9.1]# source /etc/profile
[root@hadoop01 flink-1.9.1]# which flink

5、启动测试

./bin/start-cluster.sh

6、测试：

jps

访问web地址：http://hadoop01:8081

 

启动流作业：

监控输入数据

[root@hadoop01 flink-1.9.1]#  nc -l 9000
lorem ipsum
ipsum ipsum ipsum
bye

启动job

[root@hadoop01 flink-1.9.1]# ./bin/flink run examples/streaming/SocketWindowWordCount.jar --port 9000

监控结果

[root@hadoop01 ~]# tail -f /usr/local/flink-1.9.1/log/flink-*-taskexecutor-*.out
lorem : 1
bye : 1
ipsum : 4

 

启动批次作业：

[root@hadoop01 flink-1.9.1]# flink run ./examples/batch/WordCount.jar --input /home/words --output /home/1907/out/00
Starting execution of program
Program execution finished
Job with JobID 8b258e1432dde89060c4acbac85f57d4 has finished.
Job Runtime: 3528 ms

web控制台如下图：

 

7、关闭local模式

./bin/stop-cluster.sh
