软件版本:
CentOS release 6.6 (Final)
Hdk-8u131-linux-x64
Hadoop-2.7.3
Hive-2.1.1
Apache-flume-1.7.0-bin
下载JDK、Hadoop、Hive、Flume:
[root@Hadoop-Data01 soft]# wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz
[root@Hadoop-Data01 soft]# wget http://apache.fayea.com/hadoop/common/hadoop-2.7.3/hadoop-2.7.3-src.tar.gz
[root@Hadoop-Data01 soft]# wget http://apache.fayea.com/hive/hive-2.1.1/apache-hive-2.1.1-bin.tar.gz

Hadoop部署

修改主机名,/etc/hosts文件,确保各主机DNS解析正确:
[root@Hadoop-Data01 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.194   Hadoop-Data01
192.168.0.195   Hadoop-Data02
192.168.0.196   Hadoop-Data03
注:Slave服务器内容同上.

  配置Hadoop-Master、Hadoop-Slave主机间的免key登录:

[root@Hadoop-Data01 ~]# vim /etc/ssh/sshd_config
RSAAuthentication yes
PubkeyAuthentication yes
注:这里可以通过sed:sed -i 47,48s/^#//g /etc/ssh/sshd_config
[root@Hadoop-Data01 ~]# ssh-keygen -t rsa
[root@Hadoop-Data01 .ssh]# cat authorized_keys

注:合并三台服务器/root/.ssh/id_rsa.pub文件到authorized_keys
[root@Hadoop-Data01 .ssh]# scp authorized_keys root@192.168.0.195:/root/.ssh/
[root@Hadoop-Data01 .ssh]# scp authorized_keys root@192.168.0.196:/root/.ssh/

  在各个主机上安装JDK

[root@Hadoop-Data01 soft]# tar -xf jdk-8u131-linux-x64.tar.gz
[root@Hadoop-Data01 soft]# \cp -r jdk1.8.0_131 /usr/local/
[root@Hadoop-Data01 soft]# cd /usr/local/
[root@Hadoop-Data01 local]# ln -s jdk1.8.0_131 jdk

 安装hadoop

/usr/local/hadoop/etc/hadoop/core-site.xml配置文件:
[root@Hadoop-Data01 soft]# tar -xf hadoop-2.7.3.tar.gz
[root@Hadoop-Data01 soft]# mv hadoop-2.7.3 /usr/local/
[root@Hadoop-Data01 soft]# cd /usr/local/
[root@Hadoop-Data01 local]# ln -s hadoop-2.7.3 hadoop
[root@Hadoop-Data01 hadoop]# vim core-site.xml
>>>>>
<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://192.168.0.194:9000</value>

    <property>

    <property>
        <name>io.file.buffer.size</name>
        <value>1024</value>
    </property>
</configuration>
注:
<fs.defaultFS>:默认文件系统的名称,URI形式,uri的scheme需要由(fs.SCHEME.impl)指定文件系统实现类;uri的authority部分用来指定host、port等;默认是本地文件系统。HA方式,这里设置服务名,例如:hdfs:// 192.168.0.194:9000,HDFS的客户端访问HDFS需要此参数;
<hadoop.tmp.dir>:Hadoop的临时目录,其它目录会基于此路径,本地目录。只可以设置一个值;建议设置到一个足够空间的地方,而不是默认的/tmp下,服务端参数,修改需重启;
<io.file.buffer.size>:在读写文件时使用的缓存大小,这个大小应该是内存Page的倍数,建议1M。

/usr/local/hadoop/etc/hadoop/hdfs-site.xml配置文件:
[root@Hadoop-Data01 hadoop]# vim hdfs-site.xml
>>>>>
<configuration>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>file:/usr/local/hadoop/dfs/name</value>

    <property>

    <property>
        <name>dfs.webhdfs.enabled</name>
        <value>true</value>
    </property>
</configuration>
注:
<dfs.namenode.name.dir>:本地磁盘目录,NN存储fsimage文件的地方;可以是按逗号分隔的目录列表,fsimage文件会存储在全部目录,冗余安全;这里多个目录设定,最好在多个磁盘,另外,如果其中一个磁盘故障,不会导致系统故障,会跳过坏磁盘。由于使用了HA,建议仅设置一个,如果特别在意安全,可以设置2个;
<dfs.datanode.data.dir>:本地磁盘目录,HDFS数据应该存储Block的地方。可以是逗号分隔的目录列表(典型的,每个目录在不同的磁盘),这些目录被轮流使用,一个块存储在这个目录,下一个块存储在下一个目录,依次循环;每个块在同一个机器上仅存储一份,不存在的目录被忽略;必须创建文件夹,否则被视为不存在;
<dfs.replication>:数据块副本数,此值可以在创建文件是设定,客户端可以只有设定,也可以在命令行修改;不同文件可以有不同的副本数,默认值用于未指定时。
<dfs.namenode.secondary.http-address>:SNN的http服务地址,如果是0,服务将随机选择一个空闲端口,使用了HA后,就不再使用SNN;
<dfs.webhdfs.enabled>:在NN和DN上开启WebHDFS (REST API)功能。

        <value>8192</value>
    </property>
</configuration>
注:
<mapreduce.framework.name>:MapReduce按照任务大小和设置的不同,提供了两种任务模式:①本地模式(LocalJobRunner实现)mapreduce.framework.name设置为local,则不会使用YARN集群来分配资源,在本地节点执行。在本地模式运行的任务,无法发挥集群的优势。在web UI是查看不到本地模式运行的任务。②Yarn模式(YARNRunner实现)mapreduce.framework.name设置为yarn,当客户端配置mapreduce.framework.name为yarn时, 客户端会使用YARNRunner与服务端通信, 而YARNRunner真正的实现是通过ClientRMProtocol与RM交互, 包括提交Application, 查询状态等功能。
<mapreduce.jobhistory.address>和<mapreduce.jobhistory.webapp.address>:Hadoop自带了一个历史服务器,可以通过历史服务器查看已经运行完的Mapreduce作业记录,比如用了多少个Map、用了多少个Reduce、作业提交时间、作业启动时间、作业完成时间等信息。

配置hadoop环境变量:
[root@Hadoop-Data01 hadoop]# vim /etc/profile
>>>>>
export HADOOP_HOME=/usr/local/hadoop
export PATH=$HADOOP_HOME/bin:$PATH

[root@Hadoop-Data01 hadoop]# vim hadoop-env.sh
>>>>>
export JAVA_HOME=/usr/local/jdk

添加从节点IP到Slave文件:
[root@Hadoop-Data01 hadoop]# echo > slave && echo 192.168.0.195 > slave

拷贝hadoop服务目录到从主机:
[root@Hadoop-Data01 local]# \scp -r hadoop-2.7.3 root@192.168.0.195:/usr/local/

进入Hadoop目录,启动Hadoop-Master主机上的服务:
①初始化:
[root@Hadoop-Data01 bin]# sh /usr/local/hadoop/bin/hdfs namenode -format
②启动服务:
[root@Hadoop-Data01 sbin]# sh /usr/local/hadoop/sbin/start-all.sh
③关闭服务:
[root@Hadoop-Data01 sbin]# sh /usr/local/hadoop/sbin/stop-all.sh
④查看组件:
[root@Hadoop-Data01 sbin]# jps
6517 SecondaryNameNode
6326 NameNode
6682 ResourceManager
6958 Jps

部署Flume

一、简介

  1. flume是分布式的日志收集系统,把收集来的数据传送到目的地去。
  2. flume里面有个核心概念,叫做agent。agent是一个java进程,运行在日志收集节点。
  3. agent里面包含3个核心组件:source、channel、sink。 source组件是专用于收集日志的,可以处理各种类型各种格式的日志数据,包括avro、thrift、exec、jms、spooling directory、netcat、sequence generator、syslog、http、legacy、自定义。 source组件把数据收集来以后,临时存放在channel中。 channel组件是在agent中专用于临时存储数据的,可以存放在memory、jdbc、file、自定义。 channel中的数据只有在sink发送成功之后才会被删除。 sink组件是用于把数据发送到目的地的组件,目的地包括hdfs、logger、avro、thrift、ipc、file、null、hbase、solr、自定义。
  4. 在整个数据传输过程中,流动的是event。事务保证是在event级别。
  5. flume可以支持多级flume的agent,支持扇入(fan-in)、扇出(fan-out)。

二、安装

 解压flume文件,传输到/usr/local/下(安装到hadoop服务器):

[root@Hadoop-Data01 soft]# \cp -r apache-flume-1.7.0-bin /usr/local/
[root@Hadoop-Data01 soft]# cd /usr/local/
[root@Hadoop-Data01 local]# ln -s apache-flume-1.7.0-bin flume
[root@Hadoop-Data01 conf]# cp flume-env.sh.template flume-env.sh
[root@Hadoop-Data01 conf]# vim flume-env.sh
>>>>:
export JAVA_HOME=/usr/local/jdk
[root@Hadoop-Data01 bin]# ./flume-ng version
Flume 1.7.0
Source code repository: https://git-wip-us.apache.org/repos/asf/flume.git

 下载flume服务到需要采集的服务器,这里是windows,然后配置/conf/flume-conf.properties:

a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = spooldir
a1.sources.r1.channels = c1
a1.sources.r1.spoolDir = D:\\flume\\log     #收集这个目录下的文件
a1.sources.r1.fileHeader = true
a1.sources.r1.basenameHeader = true
a1.sources.r1.basenameHeaderKey = fileName
a1.sources.r1.ignorePattern = ^(.)*\\.tmp$

a1.sinks.k1.hostname = 192.168.0.194        #接受agent端地址
a1.sinks.k1.port = 19949

# Use a channel which buffers events in memory
a1.channels.c1.type=memory  
a1.channels.c1.capacity=10000  
a1.channels.c1.transactionCapacity=1000  
a1.channels.c1.keep-alive=30  

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

 启动采集端服务,windows端:

D:\apache-flume-1.7.0-bin\bin>flume-ng.cmd agent --conf ..\conf --conf-file ..\conf\flume-conf.properties --name a1

 配置Linux端,agent配置/conf/flume-conf.properties:
