centos安装flume1.9.0

1.下载

/*
对日志收集的三个核心要素进行了抽象：
1. Source：日志从哪里产生
2. Sink：日志会被推送到什么地方
3. Channel：Source通过什么样的渠道，送到Sink
*/
cd /opt

wget https://mirror.bit.edu.cn/apache/flume/1.9.0/apache-flume-1.9.0-bin.tar.gz

tar -zxvf apache-flume-1.9.0-bin.tar.gz

cd /opt/apache-flume-1.9.0-bin/conf

2.修改配置

//查看java安装路径
echo $JAVA_HOME

cp flume-env.sh.template flume-env.sh

vim flume-env.sh
export JAVA_HOME=/usr/local/java

// 创建 job/flume-netcat-logger.conf，文件内容如下:
# 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
## 事件容量
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
## channel 与 sink 的关系是 1对多 的关系。1个sink只可以绑定1个channel，1个channel可以绑定多个sink。
a1.sinks.k1.channel = c1

3.启动

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

4.校验

//查看端口时候通
// yum install -y telnet
telnet localhost 44444
