• 技术选型
  
  

• 修改配置文件，首先是机器A

• exec-memory-avro,agent、source、sink、channel都改了名字。

# example.conf: A single-node Flume configuration

# Name the components on this agent
exec-memory-avro.sources = exec-source
exec-memory-avro.sinks = avro-sink
exec-memory-avro.channels = memory-channel

# Describe/configure the source
exec-memory-avro.sources.exec-source.type = exec

# 监控文件的更新
exec-memory-avro.sources.exec-source.command = tail -F /home/bizzbee/data/data.log
exec-memory-avro.sources.exec-source.shell = /bin/sh -c

# Describe the sink
exec-memory-avro.sinks.avro-sink.type = avro
# 输出到本机，当然也可以到别的机器
exec-memory-avro.sinks.avro-sink.hostname = spark
# 本机的44444端口
exec-memory-avro.sinks.avro-sink.port = 44444

# Use a channel which buffers events in memory
exec-memory-avro.channels.memory-channel.type = memory

# Bind the source and sink to the channel
exec-memory-avro.sources.exec-source.channels = memory-channel
exec-memory-avro.sinks.avro-sink.channel = memory-channel

*再创建一个配置文件，是B机器上的flume配置（本次实验实际上还是本机）`avro-memory-logger.conf

# Name the components on this agent
# i
avro-memory-logger.sources = avro-source
avro-memory-logger.sinks = logger-sink
avro-memory-logger.channels = memory-channel

# Describe/configure the source
avro-memory-logger.sources.avro-source.type = avro
avro-memory-logger.sources.avro-source.bind = spark
avro-memory-logger.sources.avro-source.port = 44444

# Describe the sink
avro-memory-logger.sinks.logger-sink.type = logger
# Use a channel which buffers events in memory
avro-memory-logger.channels.memory-channel.type = memory

# Bind the source and sink to the channel
avro-memory-logger.sources.avro-source.channels = memory-channel
avro-memory-logger.sinks.logger-sink.channel = memory-channel

```
* 启动，先启动B机器上的flume

```
flume-ng agent --name avro-memory-logger --conf $FLUME_HOME/conf --conf-file $FLUME_HOME/conf/avro-memory-logger.conf -Dflume.root.logger=INFO,console

```
* 然后启动A机器上的

```
flume-ng agent --name exec-memory-avro --conf $FLUME_HOME/conf --conf-file $FLUME_HOME/conf/exec-memory-avro.conf -Dflume.root.logger=INFO,console

```
* 然后同样向data.log里面添加内容，会在B看到输出。
