一:Flume的部署

下载安装包

1: Flume官网地址

[http://flume.apache.org/][http_flume.apache.org]

2:文档查看地址

[http://flume.apache.org/FlumeUserGuide.html][http_flume.apache.org_FlumeUserGuide.html]

3:下载地址

[http://archive.apache.org/dist/flume/][http_archive.apache.org_dist_flume]

4: 安装部署

1）将apache-flume-1.7.0-bin.tar.gz上传到linux的/tools目录下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI2OTYzNDMz_size_16_color_FFFFFF_t_70 1][]

2）解压apache-flume-1.7.0-bin.tar.gz到/root/training目录下

tar -zxvf apache-flume-1.7.0-bin.tar.gz -C /training/

![20191230162544105.png][]

3）修改apache-flume-1.7.0-bin的名称为flume

mv apache-flume-1.7.0-bin flume

4） 将flume/conf下的flume-env.sh.template文件修改为flume-env.sh，并配置flume-env.sh文件

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

vi flume-env.sh

export JAVA\_HOME=/opt/module/jdk1.8.0\_144

二:监控端口安装案例

1:案例需求

首先启动Flume任务，监控本机44444端口，服务端；

然后通过netcat工具向本机44444端口发送消息，客户端；

最后Flume将监听的数据实时显示在控制台。

2:需求分析

3:实现步骤

1:安装netcat工具

sudo yum install -y nc

2:判断44444端口是否被占用

sudo netstat -tunlp | grep 44444

没有被占用

![20191230162623786.png][]

功能描述：netstat命令是一个监控TCP/IP网络的非常有用的工具，它可以显示路由表、实际的网络连接以及每一个网络接口设备的状态信息。

基本语法：netstat \[选项\]

选项参数：

\-t或--tcp：显示TCP传输协议的连线状况；

\-u或--udp：显示UDP传输协议的连线状况；

\-n或--numeric：直接使用ip地址，而不通过域名服务器；

\-l或--listening：显示监控中的服务器的Socket；

\-p或--programs：显示正在使用Socket的程序识别码（PID）和程序名称；

3:创建Flume Agent配置文件flume-netcat-logger.conf

在flume目录下创建job文件夹并进入job文件夹。

\[atguigu@hadoop102 flume\]$ mkdir job

\[atguigu@hadoop102 flume\]$ cd job/

在job文件夹下创建Flume Agent配置文件flume-netcat-logger.conf。

\[atguigu@hadoop102 job\]$ touch flume-netcat-logger.conf

![20191230162642262.png][]

在flume-netcat-logger.conf文件中添加如下内容。

\[atguigu@hadoop102 job\]$ vim flume-netcat-logger.conf

添加内容如下：

\# 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

注：配置文件来源于官方手册http://flume.apache.org/FlumeUserGuide.html

4:先开启flume监听端口

第一种写法：

\[atguigu@hadoop102 flume\]$ bin/flume-ng agent --conf conf/ --name a1 --conf-file job/flume-netcat-logger.conf -Dflume.root.logger=INFO,console

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI2OTYzNDMz_size_16_color_FFFFFF_t_70 5][]

第二种写法：

\[atguigu@hadoop102 flume\]$ bin/flume-ng agent -c conf/ -n a1 –f job/flume-netcat-logger.conf -Dflume.root.logger=INFO,console

参数说明：

\--conf conf/  ：表示配置文件存储在conf/目录

\--name a1 ：表示给agent起名为a1

\--conf-file job/flume-netcat.conf ：flume本次启动读取的配置文件是在job文件夹下的flume-telnet.conf文件。

\-Dflume.root.logger==INFO,console ：-D表示flume运行时动态修改flume.root.logger参数属性值，并将控制台日志打印级别设置为INFO级别。日志级别包括:log、info、warn、error。

5:使用netcat工具向本机的44444端口发送内容(用另外一个shell窗口打开)

1:先看看端口是否存在

\[root@Test ~\]\# netstat -nltp | grep 4444

![20191230162728461.png][]

\[root@Test ~\]\# nc localhost 44444

hello

world

6:在Flume监听页面观察接收数据情况
