二、安装流程

1.下载软件包

#Master
wget http://mirror.bit.edu.cn/apache/flume/1.8.0/apache-flume-1.8.0-bin.tar.gz
tar zxvf apache-flume-1.8.0-bin.tar.gz
mv apache-flume-1.8.0-bin /usr/local/apache-flume-1.8.0-bin

2.修改Flume配置

（1）NetCat

cat  > /usr/local/apache-flume-1.8.0-bin/conf/flume-netcat.conf << EOF
# Name the components on this agent
agent.sources = r1
agent.sinks = k1
agent.channels = c1

# Describe/configuration the source
agent.sources.r1.type = netcat
agent.sources.r1.bind = 127.0.0.1
agent.sources.r1.port = 44444

# Describe the sink
agent.sinks.k1.type = logger

# Use a channel which buffers events in memory
agent.channels.c1.type = memory
agent.channels.c1.capacity = 1000
agent.channels.c1.transactionCapacity = 100

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

验证

#Server
bin/flume-ng agent --conf conf --conf-file conf/flume-netcat.conf --name=agent -Dflume.root.logger=INFO,console
#Client 
telnet master 44444

（2）Exec

cat  > /usr/local/apache-flume-1.8.0-bin/conf/flume-exec.conf << EOF
# Name the components on this agent
agent.sources = r1
agent.sinks = k1
agent.channels = c1

# Describe/configuration the source
agent.sources.r1.type = exec
agent.sources.r1.command = tail -f /data/hadoop/flume/test.txt

# Describe the sink
agent.sinks.k1.type = logger

# Use a channel which buffers events in memory
agent.channels.c1.type = memory
agent.channels.c1.capacity = 1000
agent.channels.c1.transactionCapacity = 100

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

验证

#Server
bin/flume-ng agent --conf conf --conf-file conf/flume-exec.conf --name=agent -Dflume.root.logger=INFO,console
#Client 
while true;do echo `date` >> /data/hadoop/flume/test.txt ; sleep 1; done

（3）Avro

cat  > /usr/local/apache-flume-1.8.0-bin/conf/flume-avro.conf << EOF
# Define a memory channel called c1 on agent
agent.channels.c1.type = memory

# Define an avro source alled r1 on agent and  tell it
agent.sources.r1.channels = c1
agent.sources.r1.type = avro
agent.sources.r1.bind = 127.0.0.1
agent.sources.r1.port = 44444

# Describe/configuration the source
agent.sinks.k1.type = hdfs
agent.sinks.k1.channel = c1
agent.sinks.k1.hdfs.path = hdfs://master:9000/flume_data_pool
agent.sinks.k1.hdfs.filePrefix = events-
agent.sinks.k1.hdfs.fileType = DataStream
agent.sinks.k1.hdfs.writeFormat = Text
agent.sinks.k1.hdfs.rollSize = 0
agent.sinks.k1.hdfs.rollCount= 600000
agent.sinks.k1.hdfs.rollInterval = 600

agent.channels = c1
agent.sources = r1
agent.sinks = k1
EOF

验证

#Server
bin/flume-ng agent --conf conf --conf-file conf/flume-netcat.conf --name=agent -Dflume.root.logger=DEBUG,console
#Client 
telnet master 44444
