ubuntu安装flume，修改 Flume 配置文件

首先需要java环境，可自行百度。

然后可以去官网下载flume，点击下载

下载结束后解压后目录如下

然后进入进入conf中，可先复制flume-conf.properties.template，flume-env.sh.template，未flume-conf.properties，flume-env.sh，如下所示

此时编辑flume-env.sh

找到java_home这一行去掉#，并且换为自己的jdk安装路径

flume配置文件(agent配置)主要包括agent连接的source、channel、sink名称及其相关配置

     可根据官方文档中例子，将conf中的flume-conf.properties全部替换成

# 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

然后在conf上一目录，输入命令bin/flume-ng agent --conf conf --conf-file conf/flume-conf.properties --name a1 -Dflume.root.logger=INFO,console

看到这即启动成功，此时可以打开一个终端输入telnet localhost 44444

此时输入hello world

可在前一个终端中看到
