flume服务的搭建

搭建前先统一时间，关闭防火墙，使用的jar包版本是1.6.0的

服务配置有两种方式

第一种：具体步骤如下：

1.将jar包传至node1上，解压至根目录

2.更改目录名，使用如下命令：mv apache-flume-1.6.0-bin /home/install/flume-1.6

3.进入flume-1.6目录后，vi test1，创建test1文件，打开

https://flume.apache.org/FlumeUserGuide.html链接，复制关于source、channel和sink的那一段代码

　　将其中的localhost改为node1

4.运行flume

5.打开node2，输入命令:telnet node1 44444

任意字符如hello，看node1有没有收到hello字符

Ctrl+】，quit退出，Ctrl+c终止

第二种方式：具体步骤如下：

1.先启动zookeeper服务：zkServer.sh start,再启动dfs:start-dfs.sh

2.vi test2

具体代码：

[root@node1 flume-1.6]# vi test2

a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type =spooldir
a1.sources.r1.spoolDir=/opt/flume

# Describe the sink
a1.sinks.k1.type =avro
a1.sinks.k1.hostname=node2
a1.sinks.k1.port=55555

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 100000
a1.channels.c1.transactionCapacity = 1000

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

在node2（相当于服务器）上

具体代码：
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type =avro
a1.sources.r1.bind=node2
a1.sources.r1.port=55555

# Describe the sink
a1.sinks.k1.type =hdfs
a1.sinks.k1.hdfs.path=hdfs://xiaotian/flume/%Y-%m-%d/
a1.sinks.k1.hdfs.filePrefix=%H%M
a1.sinks.k1.hdfs.rollSize=0
a1.sinks.k1.hdfs.rollCount=0
a1.sinks.k1.hdfs.rollInterval=60
a1.sinks.k1.hdfs.idleTimeout=1
a1.sinks.k1.hdfs.fileType=DataStream
a1.sinks.k1.hdfs.round=true
a1.sinks.k1.hdfs.roundValue=1
a1.sinks.k1.hdfs.roundUnit=minute
a1.sinks.k1.hdfs.useLocalTimeStamp=true

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 100000
a1.channels.c1.transactionCapacity = 1000

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

3.进入flume-1.6里的conf目录

　　mv flume-env.sh.template flume-env.sh

vi flume-env.sh

添加一句话：JAVA_OPTS="-Xms100m -Xmx300m"

4.新建一个/opt/flume目录，然后再启动flume，启动时先启动node2(改变source的),再启动node1

bin/flume-ng agent --conf conf --conf-file test2 --name a1 -Dflume.root.logger=INFO,console

启动node1后可先在node上查看进程，看是否启动成功：netstat -ntpl
