• ubuntu18.04 flink-1.9.0 Standalone集群搭建

    1. 集群规划

      Master JobManager Standby JobManager Task Manager Zookeeper
      flink01 √ √
      flink02 √ √
      flink03 √ √ √
      flink04 √ √ √

    2. 前置准备

      • 克隆4台虚拟机

      • 网络配置

        • vim /etc/netplan/01-network-manager-all.yaml 修改配置文件

        • 集群网络配置如下:

          # flink01
network:
  version: 2
  renderer: NetworkManager

  ethernets:
    ens33:
        dhcp4: no
        dhcp6: no
        addresses: [192.168.180.160/24]
        gateway4: 192.168.180.2
        nameservers:
            addresses: [114.114.114.114, 8.8.8.8]
            
 # flink02
 network:
  version: 2
  renderer: NetworkManager

  ethernets:
    ens33:
        dhcp4: no
        dhcp6: no
        addresses: [192.168.180.161/24]
        gateway4: 192.168.180.2
        nameservers:
            addresses: [114.114.114.114, 8.8.8.8]
            
# flink03
network:
  version: 2
  renderer: NetworkManager

  ethernets:
    ens33:
        dhcp4: no
        dhcp6: no
        addresses: [192.168.180.162/24]
        gateway4: 192.168.180.2
        nameservers:
            addresses: [114.114.114.114, 8.8.8.8]

   #flink04
   network:
  version: 2
  renderer: NetworkManager

  ethernets:
    ens33:
        dhcp4: no
        dhcp6: no
        addresses: [192.168.180.163/24]
        gateway4: 192.168.180.2
        nameservers:
            addresses: [114.114.114.114, 8.8.8.8]

        • 能 ping 通 baidu 连上 xshell 即可, 连不上的可能是防火墙问题, ubuntu 用的防火墙是ufw, selinux 默认是disabled, 正常来说应该不会连不上。

      • 修改 hostname 及 hosts文件

        • vim /etc/hostname 修改 hostname 为 flink01

        • vim /etc/hosts 修改 host文件

          127.0.0.1       localhost
192.168.180.160    flink01
192.168.180.161    flink02
192.168.180.162    flink03
192.168.180.163    flink04

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

      • JDK配置

        • 如果没有配置jdk请参考https://www.cnblogs.com/ronnieyuan/p/11461377.html
          • 如果之前有下过别的版本的jdk请将jdk的tar包解压到/usr/lib/jvm,然后再修改配置文件并选择jdk

      • 免密登录

        root@flink01:~# ssh-keygen -t rsa -P ""

        • 在~目录下vim .ssh/authorized_keys:

          将5台虚拟机公钥都存入该文件中, 每台的authorized_keys都一致

          ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDZGR9+3bTIq6kZ5c+1O2mvyPBM790/0QUuVcjPSREK1pMpyyKRu6CUaBlTOM8JJzkCnEe7DVKY8lV2q7Zv7VVXTLI2dKuUmo0oMSGo5ABvfjGUJfFWdNkqgrPgT+Opl/1kIqr6wTGGCJsRx+Nfkic31WhnPij2IM/Zpqu88kiXmUbaNwBDM5jaRqB/nk7DW4aMwF5oeX6LvEuI1SVmY3DH0w6Cf1EDtOyYG1f9Vof8ao88JOwRZazTNbBdsVcPKDbtvovs/lP+CrtwmAcGFGZSjA22I0dc9ek0puQ5pNUgindpb9egJJFoGhtduut6OfmmvbB8u9PjdBkHcp3Vof4j root@flink01

    3. 集群搭建

      • Zookeeper 搭建

        • 上传 tar 包 并解压到指定目录 并修改解压后的目录名称

          tar -zxvf apache-zookeeper-3.5.5-bin.tar.gz -C /opt/ronnie/

cd /opt/ronnie

mv apache-zookeeper-3.5.5-bin/ zookeeper-3.5.5

        • 创建并修改zookeeper配置文件

          • cd zookeeper-3.5.5/conf/ 进入Zookeeper配置文件目录

          • cp zoo_sample.cfg zoo.cfg 拷贝一份zoo_sample.cfg 为 zoo.cfg

          • vim zoo.cfg 修改配置文件

            # The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/opt/ronnie/zookeeper-3.5.5/data/zk
dataLogDir=/opt/ronnie/zookeeper-3.5.5/data/log
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=flink01:2888:3888
server.2=flink02:2888:3888
server.3=flink03:2888:3888
server.4=flink04:2888:3888

            • 创建data目录:

              mkdir -p /opt/ronnie/zookeeper-3.5.5/data

            • 创建data目录下的日志目录:

              mkdir -p /opt/ronnie/zookeeper-3.5.5/data/log

            • 创建data目录下的zk目录

              mkdir -p /opt/ronnie/zookeeper-3.5.5/data/zk

        • cd zk/, 创建myid, 四台虚拟机flink01, flink02, flink03, flink04 分别对应 myid 1,2,3,4

        • 添加环境变量

          • vim ~/.bashrc , 完成后 source ~/.bashrc

            # Zookeeper
export ZOOKEEPER_HOME=/opt/ronnie/zookeeper-3.5.5
export PATH=$ZOOKEEPER_HOME/bin:$PATH

        • 将Zookeeper目录传送给其他几台虚拟机(记得改myid)

          cd /opt/ronnie
scp -r zookeeper-3.5.5/ root@192.168.180.161:/opt/ronnie/
scp -r zookeeper-3.5.5/ root@192.168.180.162:/opt/ronnie/
scp -r zookeeper-3.5.5/ root@192.168.180.163:/opt/ronnie/

        • 启动Zookeeper: zkServer.sh start

        • 检查Zookeeper 状态: zkServer.sh status

        • 有显示该节点状态就表示启动成功了

          root@flink01:~# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/ronnie/zookeeper-3.5.5/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: follower

        • 报错请查看日志定位错误

      • Hadoop集群搭建(主要还是为了hdfs, On-Yarn后面再弄)

        • 集群分配

          | | NN-1 | NN-2 | DN | ZK | ZKFC | JN |
          | ------- | ---- | ---- | ---- | ---- | ---- | ---- |
          | flink01 | * | | * | * | * | * |
          | flink02 | | * | * | * | * | * |
          | flink03 | | | * | * | | * |
          | flink04 | | | * | * | | * |

    • 上传tar包并解压到指定路径:

         tar -zxvf hadoop-3.1.2.tar.gz -C /opt/ronnie

    • vim /opt/ronnie/hadoop-3.1.2/etc/hadoop/hadoop-env.sh 将 环境文件中的jdk路径替换为本机jdk路径

      export JAVA_HOME=/usr/lib/jvm/jdk1.8

      • vim /opt/ronnie/hadoop-3.1.2/etc/hadoop/mapred-env.sh, 添加:

        export JAVA_HOME=/usr/lib/jvm/jdk1.8

      • vim /opt/ronnie/hadoop-3.1.2/etc/hadoop/yarn-env.sh,添加:

export FLINK_HOME=/opt/ronnie/flink-1.9.0
export PATH=$FLINK_HOME/bin:$PATH

      • start-cluster.sh 后jps发现没有对应jobManager进程，查看flink日志发现报错:

        UnsupportedFileSystemSchemeException: Hadoop is not in the classpath/dependencies.

        • 需要去官网下载Pre-bundled Hadoop

          1572747747743

        • 将jar包上传至 flink 目录下的 lib目录

          cd /opt/ronnie/flink-1.9.0/lib

        • 将 jar 包 发送至其他三台虚拟机

          scp flink-shaded-hadoop-2-uber-2.8.3-7.0.jar root@flink02:`pwd`
scp flink-shaded-hadoop-2-uber-2.8.3-7.0.jar root@flink03:`pwd`
scp flink-shaded-hadoop-2-uber-2.8.3-7.0.jar root@flink03:`pwd`

      • start-cluster.sh 启动 flink 集群, jps查看有对应的StandaloneSessionClusterEntrypoint进程后, 打开8081端口

      • 运行一下自带的wordCount测试一下
