（一）idea工具开发数据生成模拟程序
1.在idea开发工具中构建weblogs项目（Java项目），然后设置sources目录。
在java目录下新建ReadWrite类
package main.java;
import java.io.*;
public class ReadWrite {
static String readFileName;
static String writeFileName;
public static void main(String args[]){
readFileName = args[0];
writeFileName = args[1];
try {
// readInput();
readFileByLines(readFileName);
}catch(Exception e){
}
}
public static void readFileByLines(String fileName) {
FileInputStream fis = null;
InputStreamReader isr = null;
BufferedReader br = null;
String tempString = null;
try {
System.out.println("以行为单位读取文件内容，一次读一整行：");
fis = new FileInputStream(fileName);// FileInputStream
// 从文件系统中的某个文件中获取字节
isr = new InputStreamReader(fis,"GBK");
br = new BufferedReader(isr);
int count=0;
while ((tempString = br.readLine()) != null) {
count++;
// 显示行号
Thread.sleep(300);
String str = new String(tempString.getBytes("UTF8"),"GBK");
System.out.println("row:"+count+">>>>>>>>"+tempString);
method1(writeFileName,tempString);
//appendMethodA(writeFileName,tempString);
}
isr.close();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
if (isr != null) {
try {
isr.close();
} catch (IOException e1) {
}
}
}
}
public static void method1(String file, String conent) {
BufferedWriter out = null;
try {
out = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream(file, true)));
out.write("\n");
out.write(conent);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}2.参照前面idea工具项目打包方式，将该项目打成weblogs.jar包，然后上传至bigdata-pro01.kfk.com节点的/opt/jars目录下（目录需要提前创建）
在三个节点上新建/opt/jars路径
[kfk@bigdata-pro01 ~]$ cd /opt/
[kfk@bigdata-pro01 opt]$ ll
total 16
drwxr-xr-x. 2 kfk kfk 4096 Oct 30 16:21 datas
drwxr-xr-x. 8 kfk kfk 4096 Oct 25 09:50 modules
drwxr-xr-x. 2 kfk kfk 4096 Oct 25 09:47 softwares
drwxr-xr-x. 2 kfk kfk 4096 Oct 19 09:28 tools
[kfk@bigdata-pro01 opt]$ sudo mkdir jars
[kfk@bigdata-pro01 opt]$ ll
total 20
drwxr-xr-x. 2 kfk kfk 4096 Oct 30 16:21 datas
drwxr-xr-x 2 root root 4096 Oct 31 15:29 jars
drwxr-xr-x. 8 kfk kfk 4096 Oct 25 09:50 modules
drwxr-xr-x. 2 kfk kfk 4096 Oct 25 09:47 softwares
drwxr-xr-x. 2 kfk kfk 4096 Oct 19 09:28 tools
[kfk@bigdata-pro01 opt]$ sudo chown -R kfk:kfk jars/
[kfk@bigdata-pro01 opt]$ ll
total 20
drwxr-xr-x. 2 kfk kfk 4096 Oct 30 16:21 datas
drwxr-xr-x 2 kfk kfk 4096 Oct 31 15:29 jars
drwxr-xr-x. 8 kfk kfk 4096 Oct 25 09:50 modules
drwxr-xr-x. 2 kfk kfk 4096 Oct 25 09:47 softwares
drwxr-xr-x. 2 kfk kfk 4096 Oct 19 09:28 tools
[kfk@bigdata-pro01 opt]$ cd jars/（用FileZilla或者Xftp等工具上传）
[kfk@bigdata-pro01 jars]$ ls
weblogs.jar3.将weblogs.jar分发到另外两个节点
1）在另外两个节点上分别创建/opt/jars目录
mkdir /opt/jars2）将weblogs.jar分发到另外两个节点
scp weblogs.jar bigdata-pro02.kfk.com:/opt/jars/
scp weblogs.jar bigdata-pro03.kfk.com:/opt/jars/3）分配执行权限
[kfk@bigdata-pro01 jars]$ chmod 777 weblogs.jar
[kfk@bigdata-pro01 jars]$ ll
total 4
-rwxrwxrwx 1 kfk kfk 2201 Oct 31 15:37 weblogs.jar4.编写运行模拟程序的shell脚本
1）在bigdata-pro02.kfk.com节点的/opt/datas目录下，创建weblog-shell.sh脚本。
vi weblog-shell.sh
#/bin/bash
echo "start log......"
#第一个参数是原日志文件，第二个参数是日志生成输出文件
java -jar /opt/jars/weblogs.jar /opt/datas/weblog.log /opt/datas/weblog-flume.log创建输出文件（节点2和节点3）
修改weblog-shell.sh可执行权限
chmod 777 weblog-shell.sh2）将bigdata-pro02.kfk.com节点上的/opt/datas/目录拷贝到bigdata-pro03节点.kfk.com
scp -r /opt/datas/ bigdata-pro03.kfk.com:/opt/datas/3）修改bigdata-pro02.kfk.com和bigdata-pro03.kfk.com节点上面日志采集文件路径。以bigdata-pro02.kfk.com节点为例。
vi flume-conf.properties
agent2.sources = r1
agent2.channels = c1
agent2.sinks = k1
agent2.sources.r1.type = exec
#修改采集日志文件路径，bigdata-pro03.kfk.com节点也是修改此处
agent2.sources.r1.command = tail -F /opt/datas/weblog-flume.log
agent2.sources.r1.channels = c1
agent2.channels.c1.type = memory
agent2.channels.c1.capacity = 10000
agent2.channels.c1.transactionCapacity = 10000
agent2.channels.c1.keep-alive = 5
agent2.sinks.k1.type = avro
agent2.sinks.k1.channel = c1
agent2.sinks.k1.hostname = bigdata-pro01.kfk.com
agent2.sinks.k1.port = 5555（二）编写启动flume服务程序的shell脚本
1.在bigdata-pro02.kfk.com节点的flume安装目录下编写flume启动脚本。
vi flume-kfk-start.sh
#/bin/bash
echo "flume-2 start ......"
bin/flume-ng agent --conf conf -f conf/flume-conf.properties -n agent2 -Dflume.root.logger=INFO,console然后修改一下日志目录
2.在bigdata-pro03.kfk.com节点的flume安装目录下编写flume启动脚本。
vi flume-kfk-start.sh
#/bin/bash
echo "flume-3 start ......"
bin/flume-ng agent --conf conf -f conf/flume-conf.properties -n agent3 -Dflume.root.logger=INFO,console3.在bigdata-pro01.kfk.com节点的flume安装目录下编写flume启动脚本。
vi flume-kfk-start.sh
#/bin/bash
echo "flume-1 start ......"
bin/flume-ng agent --conf conf -f conf/flume-conf.properties -n agent1 -Dflume.root.logger=INFO,console（三）编写Kafka Consumer执行脚本
1.在bigdata-pro01.kfk.com节点的Kafka安装目录下编写Kafka Consumer执行脚本
vi kfk-test-consumer.sh
#/bin/bash
echo "kfk-kafka-consumer.sh start ......"
bin/kafka-console-consumer.sh --zookeeper bigdata-pro01.kfk.com:2181,bigdata-pro02.kfk.com:2181,bigdata-pro03.kfk.com:2181 --from-beginning --topic test2.将kfk-test-consumer.sh脚本分发另外两个节点
scp kfk-test-consumer.sh bigdata-pro02.kfk.com:/opt/modules/kakfa_2.11-0.8.2.1/
scp kfk-test-consumer.sh bigdata-pro03.kfk.com:/opt/modules/kakfa_2.11-0.8.2.1/（四）启动模拟程序并测试
在bigdata-pro02.kfk.com节点和bigdata-pro03.kfk.com节点启动日志产生脚本，模拟产生日志是否正常。
/opt/datas/weblog-shell.sh 
（五）启动数据采集所有服务
1.启动Zookeeper服务
bin/zkServer.sh start2.启动hdfs服务
在启动之前别忘了我们选择使用的集群还不是HA的hdfs集群，所以需要替换过来。（在所有节点进行以下操作）
[kfk@bigdata-pro01 ~]$ cd /opt/modules/hadoop-2.6.0/etc/
[kfk@bigdata-pro01 etc]$ ls
hadoop hadoop-ha
[kfk@bigdata-pro01 etc]$ mv hadoop hadoop-dist
[kfk@bigdata-pro01 etc]$ ls
hadoop-dist hadoop-ha
[kfk@bigdata-pro01 etc]$ mv hadoop-ha hadoop
[kfk@bigdata-pro01 etc]$ ls
hadoop hadoop-dist
[kfk@bigdata-pro01 etc]$ cd ..
[kfk@bigdata-pro01 hadoop-2.6.0]$ cd data/
[kfk@bigdata-pro01 data]$ ls
jn tmp tmp-ha
[kfk@bigdata-pro01 data]$ mv tmp tmp-dist
[kfk@bigdata-pro01 data]$ ls
jn tmp-dist tmp-ha
[kfk@bigdata-pro01 data]$ mv tmp-ha tmp
[kfk@bigdata-pro01 data]$ ls
jn tmp tmp-dist然后启动dfs服务
sbin/start-dfs.sh（节点1）
sbin/hadoop-daemon.sh start zkfc（节点1和2）3.启动HBase服务
[kfk@bigdata-pro01 hadoop-2.6.0]$ cd ../hbase-0.98.6-cdh5.3.0/
[kfk@bigdata-pro01 hbase-0.98.6-cdh5.3.0]$ bin/start-hbase.sh

三个节点都作此修改。然后停掉所有进程，按照上面的步骤重新启动。
重启dfs后发现连个节点都standby状态：
解决方案：
然后重新格式化zookeeper：
[kfk@bigdata-pro01 hadoop-2.6.0]$ bin/hdfs zkfc –formatZK再次重启所有进程：
第一个节点变为active状态！
然后再启动hbase：
[kfk@bigdata-pro01 hbase-0.98.6-cdh5.3.0]$ bin/start-hbase.sh
bigdata-pro03.kfk.com: starting zookeeper, logging to /opt/modules/hbase-0.98.6-cdh5.3.0/bin/../logs/hbase-kfk-zookeeper-bigdata-pro03.kfk.com.out

创建hbase业务表
4.启动Kafka服务[kfk@bigdata-pro01 kafka_2.11-0.8.2.1]$ bin/kafka-server-start.sh config/server.properties（三个节点都执行此操作） 
创建业务数据topic（在任一节点执行以下命令）
bin/kafka-topics.sh --zookeeper localhost:2181 --create --topic weblogs --replication-factor 1 --partitions 1 
（七）环境修改
因为我们用的是flume1.7版本的，这个时候我们应该配合kafka0.9系列的，而我们用的是kafka0.8的，所以我们要换掉。首先把0.9版本的kafka上传上来：
[kfk@bigdata-pro01 flume-1.7.0-bin]$ cd /opt/softwares/
[kfk@bigdata-pro01 softwares]$ ls
apache-flume-1.7.0-bin.tar.gz hbase-0.98.6-cdh5.3.0.tar.gz kafka_2.11-0.8.2.1.tgz zookeeper-3.4.5-cdh5.10.0.tar.gz
hadoop-2.6.0.tar.gz jdk-8u60-linux-x64.tar.gz kafka_2.11-0.9.0.0.tgz
[kfk@bigdata-pro01 softwares]$ tar -zxf kafka_2.11-0.9.0.0.tgz -C ../modules/

drwxr-xr-x 15 kfk kfk 4096 Oct 22 15:56 zookeeper-3.4.5-cdh5.10.0修改配置文件：
server.properties
mkdir kafka-logs(在所有节点新建目录，用于存放日志文件)
zookeeper.properties（和zookeeper的配置文件一致）
consumer.properties
producer.properties
把kafka分发都另外的两个节点去
scp -r kafka_2.11-0.9.0.0/ bigdata-pro02.kfk.com:/opt/modules/
scp -r kafka_2.11-0.9.0.0/ bigdata-pro03.kfk.com:/opt/modules/在节点2和节点3也把相应的配置文件修改一下
server.properties
在zookeeper下把以前的topic删除掉
WATCHER::
WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0] ls /

[]启动所有节点的kafka
bin/kafka-server-start.sh config/server.properties 
创建topic
bin/kafka-topics.sh --zookeeper bigdata-pro01.kfk.com:2181,bigdata-pro02.kfk.com:2181,bigdata-pro03.kfk.com:2181 --create --topic weblogs --replication-factor 1 --partitions 1 
修改flume配置
配置flume相关环境变量
export JAVA_HOME=/opt/modules/jdk1.8.0_60
export HADOOP_HOME=/opt/modules/hadoop-2.6.0
export HBASE_HOME=/opt/modules/hbase-0.98.6-cdh5.3.0启动节点1的flume。
启动节点1的flume时报错：Bootstrap Servers must be specified，解决方案见博客：Flume启动错误之：Bootstrap Servers must be specified
修改配置后重新启动：

作以上修改，打包上传，然后重新启动节点1的flume。
在节点2和节点3产生数据
./weblog-shell.sh 
查看我们的hbase的表有么有接收到数据
bin/hbase shell执行指令：
（八）完成数据采集全流程测试（总结）
1.在bigdata-pro01.kfk.com节点上启动flume聚合脚本，将采集的数据分发到Kafka集群和hbase集群。
./flume-kfk-start.sh2.在bigdata-pro02.kfk.com节点上完成数据采集
1）使用shell脚本模拟日志产生
cd /opt/datas/
./weblog-shell.sh2）启动flume采集日志数据发送给聚合节点
./flume-kfk-start.sh3.在bigdata-pro03.kfk.com节点上完成数据采集
1）使用shell脚本模拟日志产生
cd /opt/datas/
./weblog-shell.sh2）启动flume采集日志数据发送给聚合节点
./flume-kfk-start.sh4.启动Kafka Consumer查看flume日志采集情况
bin/kafka-console-consumer.sh --zookeeper bigdata-pro01.kfk.com:2181,bigdata-pro02.kfk.com:2181,bigdata-pro03.kfk.com:2181 --topic weblogs --from-beginning5.查看hbase数据写入情况
./hbase-shell
count/scan 'weblogs'
