apache flume agent安装

来源：互联网发布：算法第四版课后题答案编辑：程序博客网时间：2024/05/16 07:08

1、Flume Agent安装（采用spoolDir模式以便获取系统、应用等日志信息）

注：使用jyapp用户安装

一台虚拟机部署了多个JAVA应用同时需要部署多个flume-agent进行监控时，

需要调整如下配置文件：

a flume-agent/conf/app.conf中的spool_Dir参数

b flume-agent/conf/flume-env.sh中的jmxremote.port参数

c logback.xml中fileNamePattern参数

d flume_spooldir.sh中的dir参数

1.1 安装环境

系统:

CentOS release 6.6

软件:

flume-agent.tar.gz

flume-agent.tar.gz和flume_spooldir.sh文件下载路径：ftp://172.21.100.61/pro/flume/flume-agent

1.2 安装步骤

1.2.1 部署Flume Agent

具体脚本（jyapp用户）：

cd /home/jyapp

mkdir flume_logs

tar -zxvf flume-agent.tar.gz

cd flume-agent

#修改flume环境变量

vi conf/flume-env.sh

具体配置解析：（注意：红色需修改）

------------------------------------------------------

export JAVA_OPTS="-Xms100m -Xmx100m -Dflume.root.logger=INFO,LOGFILE -Dflume.monitoring.type=http -Dflume.monitoring.port=34545 -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=本机IP -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"

-------------------------------------------------------------------------------------

#修改agent脚本

vi conf/app.conf

具体配置解析：（注意：红色需修改）

------------------------------------------------------

app.sources = r1

app.sinks = k1 k2

app.channels = c1

app.sources.r1.type = spooldir

app.sources.r1.spoolDir = /home/jyapp/flume_logs #定义监控的日志目录

app.sources.r1.deletePolicy = immediate

app.sources.r1.ignorePattern = ^(.)*\\.tmp$ #忽略.tmp文件

app.sources.r1.deserializer = MULTILINE #使用多行反序列化器

app.sources.r1.deserializer.maxLineLength = 60000

app.sources.r1.interceptors = i1 i2 i3

app.sources.r1.interceptors.i1.type = timestamp #设置时间戳

app.sources.r1.interceptors.i2.type = static

app.sources.r1.interceptors.i2.key = flume.client.ip

app.sources.r1.interceptors.i2.value = 客户机IP地址 #设置IP地址

app.sources.r1.interceptors.i3.type = static

app.sources.r1.interceptors.i3.key = flume.client.system.flag

app.sources.r1.interceptors.i3.value = 客户机系统标示 #设置系统标示，如S001

app.channels.c1.type = memory

app.channels.c1.capacity = 1000

app.channels.c1.transactionCapacity = 1000

app.channels.c1.keep-alive = 3

app.channels.c1.byteCapacityBufferPercentage = 30

app.channels.c1.byteCapacity = 104857600

app.sinks.k1.type = avro
app.sinks.k1.hostname = 172.19.100.92
app.sinks.k1.port = 44466

app.sinks.k2.type = avro
app.sinks.k2.hostname = 172.19.100.102
app.sinks.k2.port = 44466

app.sources.r1.channels = c1

app.sinks.k1.channel = c1

app.sinks.k2.channel = c1

app.sinkgroups = g1
app.sinkgroups.g1.sinks = k1 k2
app.sinkgroups.g1.processor.type = load_balance
app.sinkgroups.g1.processor.backoff = true
app.sinkgroups.g1.processor.selector = round_robin

-------------------------------------------------------------------------------------

批量替换命令参考：

#修改flume-env.sh

sed -i 's/172.18.100.159/172.19.100.73/g;s/S000/S001/g' /home/jyapp/flume-agent/conf/flume-env.sh

#修改app.conf

sed -i 's/172.18.100.159/172.19.100.73/g;s/S000/S001/g' /home/jyapp/flume-agent/conf/app.conf

后台启动agent

cd /home/jyapp/flume-agent

bin/flume-ng agent --conf conf --conf-file conf/app.conf --name app &

停止agent，使用kill命令
