本文目的是根据前文的博文，打造一个Hadoop、Sprak的服务器闭环。也是经验归纳。
CentOS: Linux localhost.localdomain 3.10.0-862.el7.x86_64 #1 SMP Fri Apr 20 16:44:24 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
JDK: Oracle jdk1.8.0_241 , https://www.oracle.com/java/technologies/javase-jdk8-downloads.html
Hadoop : hadoop-3.2.1.tar.gz
Flume：apache-flume-1.9.0-bin.tar.gz , http://flume.apache.org/download.html
Hadoop：CentOS7 部署 Hadoop 3.2.1 (伪分布式)
Nginx： 请参考 CentOS 6.7 配置 yum 安装 nginx
mkdir /data/server/flume/ wget https://mirrors.tuna.tsinghua.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 mv apache-flume-1.9.0-bin 1.9.0
下载Java SDK，前往 https://www.oracle.com/java/technologies/javase-jdk8-downloads.html 下载
rz #选择你下载好的文件，上传到当前目录下 tar zxvf jdk-8u241-linux-x64.tar.gz
编辑env文件
cp 1.9.0/conf/flume-env.sh.template 1.9.0/conf/flume-env.sh
vi 1.9.0/conf/flume-env.sh
在文件末尾添加如下内容：
export JAVA_HOME=/data/server/flume/jdk1.8.0_241/
新建配置文件 flume.conf
cp 1.9.0/conf/flume-conf.properties.template 1.9.0/conf/flume.conf
vi 1.9.0/conf/flume.conf
添加如下内容：
##配置Agent myagent.sources = r1 myagent.sinks = k1 myagent.channels = c1 # # 配置Source myagent.sources.r1.type = exec myagent.sources.r1.channels = c1 myagent.sources.r1.deserializer.outputCharset = UTF-8 # # 配置需要监控的日志输出文件 myagent.sources.r1.command = tail -F /usr/local/nginx/logs/flume-test.access.log # # 配置Sink myagent.sinks.k1.type = hdfs myagent.sinks.k1.channel = c1 myagent.sinks.k1.hdfs.useLocalTimeStamp = true myagent.sinks.k1.hdfs.path = hdfs://172.16.1.126:9000/flume/nginx_logs/%Y%m%d myagent.sinks.k1.hdfs.filePrefix = %Y-%m-%d-%H myagent.sinks.k1.hdfs.fileSuffix = .log myagent.sinks.k1.hdfs.minBlockReplicas = 1 myagent.sinks.k1.hdfs.fileType = DataStream myagent.sinks.k1.hdfs.writeFormat = Text myagent.sinks.k1.hdfs.rollInterval = 86400 myagent.sinks.k1.hdfs.rollSize = 1000000 myagent.sinks.k1.hdfs.rollCount = 10000 myagent.sinks.k1.hdfs.idleTimeout = 0 # # 配置Channel myagent.channels.c1.type = memory myagent.channels.c1.capacity = 1000 myagent.channels.c1.transactionCapacity = 100 # # 将三者连接 myagent.sources.r1.channel = c1 myagent.sinks.k1.channel = c1
start_flume.sh
#!/usr/bin/env bash CURRENT_DIR=$(pwd) BIN_DIR="/data/server/flume/1.9.0/" CHECK_PID="ps aux | grep \"${BIN_DIR}\" | grep ‘flume‘ | grep -v grep | awk ‘{print \$2}‘" cd ${BIN_DIR} FLUME_PID=$(eval ${CHECK_PID}) if [ ""x != "${FLUME_PID}"x ] ;then echo "Flume is running, please kill the flume process" cd ${CURRENT_DIR} exit 0 fi nohup ./bin/flume-ng agent --conf ./conf -f ./conf/flume.conf --name myagent > ../nohup.out 2>&1 & #等3秒后执行下一条 sleep 3 FLUME_PID=$(eval ${CHECK_PID}) if [ ""x != "${FLUME_PID}"x ] ;then echo "Flume is running!" fi cd ${CURRENT_DIR}
stop_flume.sh
#!/usr/bin/env bash CURRENT_DIR=$(pwd) BIN_DIR="/data/server/flume/1.9.0/" CHECK_PID="ps aux | grep \"${BIN_DIR}\" | grep ‘flume‘ | grep -v grep | awk ‘{print \$2}‘" cd ${BIN_DIR} FLUME_PID=$(eval ${CHECK_PID}) if [ ""x == "${FLUME_PID}"x ] ;then echo "Flume is no runnig" cd ${CURRENT_DIR} exit 0 fi kill -9 $FLUME_PID echo "Flume is stop!" cd ${CURRENT_DIR}
1.安装请参考：请参考 CentOS 6.7 配置 yum 安装 nginx
2.设置 Nginx 日志打印格式为JSON字符串
编辑 /etc/nginx/nginx.cnf , 在 http{} 节点查找关键字 log_format ，另起一行增加如下内容：、
log_format post_json ‘{"remote_addr":"$remote_addr","http_x_forwarded_for":"$http_x_forwarded_for","remote_user":"$remote_user","time_local":"$time_local","server_protocol":"$server_protocol","request_time":"$request_time","request_method":"$request_method","request_uri":"$request_uri","status":$status,"body_bytes_sent":$body_bytes_sent,"http_token":"$http_token","http_referer":"$http_referer","http_user_agent":"$http_user_agent","request_body":"$request_body"}‘;
增加一个你的测试web， /etc/nginx/conf.d/test.flume.conf
server { listen 8881; access_log logs/flume-test.access.log post_json; location / { root /data/www/test; index index.html index.htm; } }
重载配置
nginx -s reload
至此配置完毕！
1.启动服务：
./1.9.0/bin/flume-ng agent --conf 1.9.0/conf/ -f 1.9.0/conf/flume.conf --name myagent
出现如下报错：

原因是 guava jar包版本过低，前往 Maven 仓库下载一个最新的包：guava-28.1-jre.jar ，参考：https://blog.csdn.net/GQB1226/article/details/102555820
移除旧版本
mv 1.9.0/lib/guava-11.0.2.jar ./ wget https://repo1.maven.org/maven2/com/google/guava/guava/28.1-jre/guava-28.1-jre.jar -P 1.9.0/lib/
