flume---高级配置5种

 

1-01  //以varo 形式接收的数据

1)Replicating Channel Selector
Flume支持Fan out流从一个源到多个通道。有两种模式的Fan out，分别是复制和复用。在复制的情况下，流的事件被发送到所有的配置通道。
在复用的情况下，事件被发送到可用的渠道中的一个子集。Fan out流需要指定源和Fan out通道的规则。
这次我们需要用到master,slave1两台机器。

 2.     http 进行分类  接收数据

将数据分类 multiplexing

将一个source端采集的数据   给两个channel

根据header 头

不是副本形式 是header头是那个 给那个 

vim complex.conf

 //将下面配置放入

a1.sources = s1
a1.channels = c1 c2
a1.sinks = k1 k2

# For each one of the sources, the type is defined

# Each channel's type is defined.
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

a1.channels.c2.type = memory
a1.channels.c2.capacity = 1000
a1.channels.c2.transactionCapacity = 100

//将其他两台机器都开启  
否则连接不上

//输入命令

[root@linux05 conf]# flume-ng agent -c . -f complex.conf -n a1 -Dflume.root.logger=info,console

//启动成功后 用java测试

3.

一个failover给两台failover  默认只给一台   当这台挂了 给另一台  不会坏 高可靠性

**********************************************************************

//将前面两台机器启动
//输入命令

[root@linux05 conf]# flume-ng agent -c . -f failover.conf -n a1 -Dflume.root.logger=info,console

//监控文件夹
//查看监控

 //默认给了06机器  他的优先级高

//要是报错了  就说明宕机了 就给了另一台机器

 

 

 

 

 

5. 负载均衡   也是两个sinks端  组成一个组  一个source   给一个channel   一个channel给两个sinks
