flume安装和使用flume1.5传输数据(日志)到hadoop2.2

安装flume1.5

1.下载安装包

（1）官网下载

apache-flume-1.5.0-bin.tar.gz

apache-flume-1.5.0-src.tar.gz

（2）百度网盘下载

我们走到这一步，我们会想到一个问题，我的电脑是32位的，不知道能否安装？如果我的电脑是64位的，能否安装。之前我们装的hadoop就分为32位和64位，想到这个问题是正常的，但是这里不用担心，因为我们下载的是二进制包，也就是说你32位和64位都可以安装。

2.分别解压：

下载之后，我们看到下面两个包：

（1）上传Linux



上面两个包，可以下载到window，然后通过WinSCP上传。

（2）解压包

解压apache-flume-1.5.0-bin.tar.gz，解压到usr文件夹下面

sudo tar zxvf apache-flume-1.5.0-bin.tar.gz

复制代码



解压apache-flume-1.5.0-src.tar.gz，解压到usr文件夹下面

sudo tar zxvf apache-flume-1.5.0-src.tar.gz

复制代码



(3) src里面文件内容，覆盖解压后bin文件里面的内容

sudo cp -ri apache-flume-1.5.0-src/* apache-flume-1.5.0-bin

复制代码



(4)重命名

mv apache-flume-1.5.0-bin/ flume

复制代码



3.配置环境变量：



配置环境变量生效

source /etc/environment

复制代码

3.建立配置文件

这里面的配置文件还是比较特别的，不同于以往我们安装的软件，我们这里可以自己建立配置文件。

首先我们建立一个 example文件

vi example

复制代码

，然后把下面内容，粘帖到里面就可以了，注意不要有乱码，有乱码的话，可以直接创建一个文件，然后上传。方法也有很多，能解决就好。

对于下面红字部分，记得创建文件夹，并且注意他们的权限一致，这个比较简单的，就不在书写了。对于下面的配置项，可以参考flume参考文档，这里面的参数很详细。

agent1表示代理名称

agent1.sources=source1

agent1.sinks=sink1

agent1.channels=channel1

#配置source1

agent1.sources.source1.type=spooldir

agent1.sources.source1.spoolDir=/usr/aboutyunlog

agent1.sources.source1.channels=channel1

agent1.sources.source1.fileHeader = false

#配置sink1

agent1.sinks.sink1.type=hdfs

agent1.sinks.sink1.hdfs.path=hdfs://master:8020/aboutyunlog

agent1.sinks.sink1.hdfs.fileType=DataStream

agent1.sinks.sink1.hdfs.writeFormat=TEXT

agent1.sinks.sink1.hdfs.rollInterval=4

agent1.sinks.sink1.channel=channel1

#配置channel1

agent1.channels.channel1.type=file

agent1.channels.channel1.checkpointDir=/usr/aboutyun_tmp123

agent1.channels.channel1.dataDirs=/usr/aboutyun_tmp



4.启动flume

flume-ng agent -n agent1 -c conf -f /usr/flume/conf/example -Dflume.root.logger=DEBUG,console

上面注意红字部分，是我们自己建立的文件，而对于绿色部分，则是输出调试信息，也可以在配置文件中配置。

5.我们启动flume之后

会看到下面信息，并且信息不停的重复。这个其实是在空文件的时候，监控的信息输出。



一旦有文件输入，我们会看到下面信息。

注意：这个不要关闭，我们另外开启一个shell，在监控文件夹中放入要上传的文件

比如我们在监控文件夹下，创建一个test1文件，内容如下



这时候flume监控shell，会有相应的如下下面变化

上传成功之后，我们去hdfs上，查看上传文件：



这样我们做到了flume上传到hadoop2.2。
