数仓项目6.0配置大全(hadoop/Flume/zk/kafka/mysql配置)

配置背景

我使用的root用户,懒得加sudo

所有文件夹在/opt/module

所有安装包在/opt/software

所有脚本文件在/root/bin

三台虚拟机:hadoop102-103-104

分发脚本 fenfa,放在~/bin下,chmod 777 fenfa给权限

#!/bin/bash
#1. 判断参数个数
if [ $# -lt 1 ]
then
 echo XXXXXXXXX No Arguement XXXXXXXXX!
 exit;
fi
#2. 遍历集群所有机器
for host in hadoop103 hadoop104
do
 echo ==================== $host ====================
 #3. 遍历所有目录,挨个发送
 for file in $@
 do
 #4. 判断文件是否存在
 if [ -e $file ]
 then
 #5. 获取父目录
 pdir=$(cd -P $(dirname $file); pwd)
 #6. 获取当前文件的名称
 fname=$(basename $file)
 ssh $host "mkdir -p $pdir"
 rsync -av $pdir/$fname $host:$pdir
 else
 echo $file does not exists!
 fi
 done
done

       注意:NameNode和SecondaryNameNode不要安装在同一台服务器

       注意:ResourceManager也很消耗内存,不要和NameNode、SecondaryNameNode配置

集群安装步骤 

下载https://archive.apache.org/dist/hadoop/common/hadoop-3.3.4/hadoop-3.3.4.tar.gz

用xftp工具把安装包传到/opt/software

 解压安装包

cd /opt/software/

tar -zxvf hadoop-3.3.4.tar.gz -C /opt/module/

改名、软连接(为了之后使用方便)

cd /opt/module

mv hadoop-3.3.4XXX hadoop-334

ln -s hadoop-334 hadoop

环境变量

vim /etc/profile.d/my_env.sh

#HADOOP_HOME

export HADOOP_HOME=/opt/module/hadoop

export PATH=$PATH:$HADOOP_HOME/bin

export PATH=$PATH:$HADOOP_HOME/sbin

分发hadoop和环境变量

启动

如果集群是第一次启动,需要在hadoop102节点格式化NameNode(注意格式化之前,一定要先停止上次启动的所有namenodedatanode进程,然后再删除datalog数据)

hdfs namenode -format

start-dfs.sh
start-yarn.sh

Web端查看HDFS的Web页面:http://hadoop102:9870/

启停脚本

#!/bin/bash
if [ $# -lt 1 ]
then
    echo "No Args Input..."
    exit ;
fi
case $1 in
"start")
        echo " =================== 启动 hadoop集群 ==================="

        echo " --------------- 启动 hdfs ---------------"
        ssh hadoop102 "/opt/module/hadoop/sbin/start-dfs.sh"
        echo " --------------- 启动 yarn ---------------"
        ssh hadoop103 "/opt/module/hadoop/sbin/start-yarn.sh"
        echo " --------------- 启动 historyserver ---------------"
        ssh hadoop102 "/opt/module/hadoop/bin/mapred --daemon start historyserver"
;;
"stop")
        echo " =================== 关闭 hadoop集群 ==================="

        echo " --------------- 关闭 historyserver ---------------"
        ssh hadoop102 "/opt/module/hadoop/bin/mapred --daemon stop historyserver"
        echo " --------------- 关闭 yarn ---------------"
        ssh hadoop103 "/opt/module/hadoop/sbin/stop-yarn.sh"
        echo " --------------- 关闭 hdfs ---------------"
        ssh hadoop102 "/opt/module/hadoop/sbin/stop-dfs.sh"
;;

    echo "Input Args Error..."

Zookeeper

步骤

Index of /zookeeper

tar -zxvf apache-zookeeper-3.7.1-bin.tar.gz -C /opt/module/

mv apache-zookeeper-3.7.1-bin/ zookeeper

在/opt/module/zookeeper/目录下创建zkData

在/opt/module/zookeeper/zkData目录下创建一个myid的文件

在文件中添加与server对应的编号,hadoop102写2,103写3,104写4

2

配置zoo.cfg文件

重命名/opt/module/zookeeper/conf目录下的zoo_sample.cfg为zoo.cfg

修改数据存储路径配置

dataDir=/opt/module/zookeeper/zkData

#######################cluster##########################

server.2=hadoop102:2888:3888

server.3=hadoop103:2888:3888

server.4=hadoop104:2888:3888

fenfa整个zookeeper文件夹

记得修改myid文件

启动

#!/bin/bash

case $1 in
"start"){
	for i in hadoop102 hadoop103 hadoop104
	do
        echo ---------- zookeeper $i 启动 ------------
		ssh $i "/opt/module/zookeeper/bin/zkServer.sh start"
	done
};;
"stop"){
	for i in hadoop102 hadoop103 hadoop104
	do
        echo ---------- zookeeper $i 停止 ------------    
		ssh $i "/opt/module/zookeeper/bin/zkServer.sh stop"
	done
};;
"status"){
	for i in hadoop102 hadoop103 hadoop104
	do
        echo ---------- zookeeper $i 状态 ------------    
		ssh $i "/opt/module/zookeeper/bin/zkServer.sh status"
	done
};;
esac

Kafka

步骤

Apache Kafka

tar -zxvf kafka_2.12-3.3.1.tgz -C /opt/module/

mv kafka_2.12-3.3.1/ kafka

进入到/opt/module/kafka

vim config/server.properties

#broker的全局唯一编号,不能重复,只能是数字。

broker.id=0

#broker对外暴露的IP和端口 (每个节点单独配置)

advertised.listeners=PLAINTEXT://hadoop102:9092

#kafka运行日志(数据)存放的路径,路径不需要提前创建,kafka自动帮你创建,可以配置多个磁盘路径,路径与路径之间可以用","分隔

log.dirs=/opt/module/kafka/datas

#配置连接Zookeeper集群地址(在zk根目录下创建/kafka,方便管理)

zookeeper.connect=hadoop102:2181,hadoop103:2181,hadoop104:2181/kafka

fenfa整个kafka文件夹

分别在hadoop103和hadoop104上修改配置文件/opt/module/kafka/config/server.properties中的broker.id(三个虚拟机分别是1/2/3)advertised.listeners

在/etc/profile.d/my_env.sh文件中增加kafka环境变量配置

vim /etc/profile.d/my_env.sh

#KAFKA_HOME

export KAFKA_HOME=/opt/module/kafka

export PATH=$PATH:$KAFKA_HOME/bin

fenfa环境变量

启动

#! /bin/bash

case $1 in
"start"){
    for i in hadoop102 hadoop103 hadoop104
    do
        echo " --------启动 $i Kafka-------"
        ssh $i "/opt/module/kafka/bin/kafka-server-start.sh -daemon /opt/module/kafka/config/server.properties"
    done
};;
"stop"){
    for i in hadoop102 hadoop103 hadoop104
    do
        echo " --------停止 $i Kafka-------"
        ssh $i "/opt/module/kafka/bin/kafka-server-stop.sh "
    done
};;
esac

Flume

步骤

Index of /dist/flume

(1)将apache-flume-1.10.1-bin.tar.gz上传到linux的/opt/software目录下

(2)解压apache-flume-1.10.1-bin.tar.gz到/opt/module/目录下

mv /opt/module/apache-flume-1.10.1-bin /opt/module/flume

vim conf/log4j2.xml

    
      /opt/module/flume/log
    

# 引入控制台输出,方便学习查看日志
    
      
      加上这一行
    

不用分发

配置采集文件

创建Flume配置文件

在hadoop102节点的Flume的job目录下创建file_to_kafka.conf。

#定义组件
a1.sources = r1
a1.channels = c1

#配置source
a1.sources.r1.type = TAILDIR
a1.sources.r1.filegroups = f1
a1.sources.r1.filegroups.f1 = /opt/module/applog/log/app.*
a1.sources.r1.positionFile = /opt/module/flume/taildir_position.json
这里真泥马坑,不知道尚硅谷怎么顺利运行的,
这里如果taildir_position.json的上级目录存在,是无法运行的,需要多加一个不存在的目录

#配置channel
a1.channels.c1.type = org.apache.flume.channel.kafka.KafkaChannel
a1.channels.c1.kafka.bootstrap.servers = hadoop102:9092,hadoop103:9092
a1.channels.c1.kafka.topic = topic_log
a1.channels.c1.parseAsFlumeEvent = false

#组装 
a1.sources.r1.channels = c1

测试

#!/bin/bash

case $1 in
"start"){
    echo " --------启动 hadoop102 采集flume-------"
    ssh hadoop102 "nohup /opt/module/flume/bin/flume-ng agent -n a1 -c /opt/module/flume/conf/ -f /opt/module/flume/job/file_to_kafka.conf >/dev/null 2>&1 &"
};; 
"stop"){
    echo " --------停止 hadoop102 采集flume-------"
    ssh hadoop102 "ps -ef | grep file_to_kafka | grep -v grep |awk  '{print \$2}' | xargs -n1 kill -9 "
};;
esac
