flume安装及配置介绍(转载)
Flume的下载方式：
wget http://www.apache.org/dyn/closer.lua/flume/1.6.0/apache-flume-1.6.0-bin.tar.
下载完成之后，使用tar进行解压
tar -zvxf apache-flume-1.6..0-bin.tar.
进入flume的conf配置包中，使用命令touch flume.conf，然后cp flume-conf.properties.template flume.conf
使vim/gedit flume.conf 编辑配置文件,需要说明的的是,Flume conf文件用的是Java版的property文件的key-value键值对模式.
在Flume配置文件中,我们需要
1. 需要命名当前使用的Agent的名称.
2. 命名Agent下的source的名字.
3. 命名Agent下的channal的名字.
4. 命名Agent下的sink的名字.
5. 将source和sink通过channal绑定起来.
一般来说,在Flume中会存在着多个Agent,所以我们需要给它们分别取一个名字来区分它们,注意名字不要相同,名字保持唯一!
例如:
#Agent取名为 agent_name
#source 取名为 source_name ,一次类推
agent_name.source=source_name
agent_name.channels=channel_name
agent_name.sinks= sink_name
上图对应的是单个Agent,单个sink,单个channel情况,如下图
如果我们需要在一个Agent上配置n个sink,m个channel(n>1, m>1),
那么只需要这样配置即可:
#Agent取名为 agent_name
#source 取名为 source_name ,一次类推
agent_name.source=source_name ,source_name1
agent_name.channels=channel_name,channel_name1
agent_name.sinks= sink_name,sink_name1
上面的配置就表示一个Agent中有两个 source,sink,channel的情况,如图所示
以上是对多sink,channel,source情况,对于 多个Agent,只需要给每个Agent取一个独一无二的名字即可!
Flume支持各种各样的sources,sinks,channels,它们支持的类型如下:
以上的类型,你可以根据自己的需求来搭配组合使用,当然如果你愿意,你可以为所欲为的搭配.比如我们使用Avro source类型,采用Memory channel,使用HDFS sink存储,那我们的配置可以接着上的配置这样写
#Agent取名为 agent_name
#source 取名为 source_name ,一次类推
agent_name.source=Avro
agent_name.channels=MemoryChannel
agent_name.sinks= HDFS
当你命名好Agent的组成部分后,你还需要对Agent的组成sources , sinks, channles去一一描述. 下面我们来逐一的细说；
Source的配置
注： 需要特别说明，在Agent中对于存在的N(N>1)个source，其中的每一个source都需要单独进行配置，首先我们需要对source的type进行设置，然后在对每一个type进行对应的属性设置.其通用的模式如下：
agent_name.sources. source_name.type =value
agent_name.sources. source_name.property2=value
agent_name.sources. source_name.property3= value
具体的例子，比如我们Source选用的是Avro模式
#Agent取名为 agent_name
#source 取名为 source_name ,一次类推
agent_name.source=Avro
agent_name.channels=MemoryChannel
agent_name.sinks=HDFS
#——————————sourcec配置——————————————#
agent_name.source.Avro.type=avro
agent_name.source.Avro.bind=localhost
agent_name.source.Avro.port= 9696#将source绑定到MemoryChannel管道上
agent_name.source.Avro.channels= MemoryChannel
Channels的配置
Flume在source和sink配间提供各种管道（channels）来传递数据.因而和source一样，它也需要配置属性，同source一样，对于N（N>0）个channels,
需要单个对它们注意设置属性，它们的通用模板为：
agent_name.channels.channel_name.type =value
agent_name.channels.channel_name. property2=value
agent_name.channels.channel_name. property3= value
具体的例子，假如我们选用memory channel类型，那么我先要配置管道的类型
agent_name.channels.MemoryChannel.type = memory
但是我们现在只是设置好了管道自个儿属性，我们还需要将其和sink，source链接起来，也就是绑定，绑定设置如下，我们可以分别写在source，sink处，也可以集中写在channel处
agent_name.sources.Avro.channels =MemoryChannel
agent_name.sinks.HDFS.channels= MemoryCHannel
Sink的配置
sink的配置和Source配置类似，它的通用格式：
agent_name.sinks. sink_name.type =value
agent_name.sinks. sink_name.property2=value
agent_name.sinks. sink_name.property3= value
具体例子，比如我们设置Sink类型为HDFS ,那么我们的配置单就如下：
agent_name.sinks.HDFS.type =hdfs
agent_name.sinks.HDFS.path= HDFS‘s path
以上就是对Flume的配置文件详细介绍，下面在补全一张完整的配置图：
