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:

部署Flume
一、简介
- 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。
- 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。
- 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。
- 在整个数据传输过程中,流动的是event。事务保证是在event级别。
- 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 Revision: 511d868555dd4d16e6ce4fedc72c2d1454546707 Compiled by bessbd on Wed Oct 12 20:51:10 CEST 2016 From source with checksum 0d21b3ffdc55a07e1d08875872c00523
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:
