Flume搭建

Apache Flume 是一个分布式, 可靠的, 高效的采集系统,从不同地方聚合和移动大量日志数据进行集中数据存储 


System Requirements
系统环境请求

Java Runtime Environment - Java 1.6 or later (Java 1.7 Recommended)
Memory - Sufficient memory for configurations used by sources, channels or sinks
Disk Space - Sufficient disk space for configurations used by channels or sinks
Directory Permissions - Read/Write permissions for directories used by agent


安装配置好java环境变量即可

Data flow model

 

 

基本配置

新建配置文件 example.conf

# example.conf: A single-node Flume configuration

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444

# Describe the sink
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

$ bin/flume-ng agent --conf conf --conf-file example.conf --name a1 -Dflume.root.logger=INFO,console


注意，name是与你配置写的前缀名字一样

 

 

测试结果

$ telnet localhost 44444
