flink 1.7.2 安装详解

##flink 1.7.2 安装
需要java环境

下载地址 https://flink.apache.org/downloads.html
#1、单机版

#创建用户flink
useradd flink -d /home/flink
echo "flink123" | passwd flink --stdin

#解压
tar -zxvf flink-1.7.2-bin-hadoop26-scala_2.11.tgz

#启动
cd flink-1.7.2/bin/ && ./start-cluster.sh

#测试
1、web页面查看:ip:8081 例如:http://192.168.88.132:8081
2、运行实例wordcount程序:cd flink-1.7.2/bin/ && ./flink run ../examples/batch/WordCount.jar
3、jps 查看进程


#2、独立集群版
#准备机器 /etc/hosts
192.168.88.130 lgh
192.168.88.131 lgh1
192.168.88.132 lgh2

#创建用户flink(所有机器)
useradd flink -d /home/flink
echo "flink123" | passwd flink --stdin

#ssh免密登录(在192.168.88.130,指定一台操作)
su - flink
ssh-keygen -t rsa
ssh-copy-id 192.168.88.131
ssh-copy-id 192.168.88.132

#解压
tar -zxvf flink-1.7.2-bin-hadoop26-scala_2.11.tgz

cd flink-1.7.2/conf

#修改配置文件
#1、masters
192.168.88.130:8081

#2、slaves
192.168.88.131
192.168.88.132

#3、flink-conf.yaml
cat flink-conf.yaml | grep -v ^# | grep -v "^$"

jobmanager.rpc.address: 192.168.88.130
jobmanager.rpc.port: 6123
env.java.home: /usr/java/default
jobmanager.heap.size: 1024m
taskmanager.heap.size: 1024m
taskmanager.numberOfTaskSlots: 1
parallelism.default: 1
rest.port: 8081

#分发flink
scp -r flink-1.7.2 flink@192.168.88.131/home/flink
scp -r flink-1.7.2 flink@192.168.88.132/home/flink

#启动
在主节点上:cd flink-1.7.2/bin/ && ./start-cluster.sh

#测试
1、web页面查看:ip:8081 例如:http://192.168.88.132:8081
2、运行实例wordcount程序:cd flink-1.7.2/bin/ && ./flink run ../examples/batch/WordCount.jar
3、jps 查看


#3、基于yarn的集群版(前提是安装好了hadoop)
hadoop的安装:可参考https://www.cnblogs.com/zsql/p/10736420.html
在独立集群的基础上:新增如下

#配置hadoop的环境变量 /etc/profile 或者 ~/.bashrc
export HADOOP_HOME=/apps/opt/cloudera/parcels/CDH/lib/hadoop
export HADOOP_CONF_DIR=/etc/hadoop/conf
export YARN_CONF_DIR=/etc/hadoop/conf

然后使用source命令使配置文件生效

#分发flink
scp -r flink-1.7.2 flink@192.168.88.131/home/flink
scp -r flink-1.7.2 flink@192.168.88.132/home/flink

#启动集群和yarn-session
cd flink-1.7.2 && ./start-cluster.sh
cd flink-1.7.2 && nohup ./bin/yarn-session.sh &

#测试
1、jps 查看进程
2、执行程序:./bin/flink run -m yarn-cluster -yn 2 ./examples/batch/WordCount.jar
然后去hadoop的yarn页面查看作业,ip:8088

 

#4、高可用版(安装zookeeper,或者修改conf/zoo.cfg,推荐安装zookeeper)
zookeeper的安装可以参考:https://www.cnblogs.com/zsql/p/10736420.html

在基于yarn版本集群的基础上修改如下配置:
#1、masters
192.168.88.130:8081
192.168.88.131:8082

#2、flink-conf.yaml (一定要注意空格..踩过坑)
jobmanager.rpc.address: 192.168.88.130
jobmanager.rpc.port: 6123
env.java.home: /usr/java/default
jobmanager.heap.size: 1024m
taskmanager.heap.size: 1024m
taskmanager.numberOfTaskSlots: 1
parallelism.default: 1
high-availability: zookeeper
high-availability.zookeeper.path.root:/user/flink/root 
high-availability.storageDir: hdfs:///user/flink/ha/ #该目录flink用户一定要有权限
high-availability.zookeeper.quorum: 192.168.88.130:2181,192.168.88.131:2181,192.168.88.132:2181
rest.port: 8081

#分发flink
scp -r flink-1.7.2 flink@192.168.88.131/home/flink
scp -r flink-1.7.2 flink@192.168.88.132/home/flink

#测试如上yarn集群
新增测试,kill掉一个主节点进程,看是否能跑作业
