一、軟體環境：

作業系統：CentOS release 6.5 (Final)
java版本: jdk1.8
zookeeper版本: zookeeper-3.4.11
kafka 版本: kafka_2.11-1.1.0.tgz
maxwell版本：maxwell-1.16.0.tar.gz
注意 ： 關閉所有機器的防火牆，同時注意啟動可以相互telnet ip 埠

二、環境部署

1、安裝jdk

export JAVA_HOME=/usr/java/jdk1.8.0_181
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$CLASSPATH

2、安裝maven

參考：https://www.cnblogs.com/wcwen1990/p/7227278.html

3、安裝zookeeper

1）下載軟體：

wget http://101.96.8.157/archive.apache.org/dist/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz
tar zxvf zookeeper-3.4.11.tar.gz 
mv zookeeper-3.4.11 /usr/local/zookeeper

2）修改環境變數

編輯 /etc/profile 檔案, 在檔案末尾新增以下環境變數配置:

# ZooKeeper Env
export ZOOKEEPER_HOME=/usr/local/zookeeper
export PATH=$PATH:$ZOOKEEPER_HOME/bin

執行以下命令使環境變數生效: source /etc/profile

3）重新命名配置檔案

初次使用 ZooKeeper 時,需要將$ZOOKEEPER_HOME/conf 目錄下的 zoo_sample.cfg 重新命名為 zoo.cfg

mv  $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg

4）單機模式--修改配置檔案
建立目錄/usr/local/zookeeper/data 和/usr/local/zookeeper/logs 修改配置檔案

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/zookeeper/data
dataLogDir=/usr/local/zookeeper/logs
clientPort=2181

5）啟動zookeeper

# bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

6）驗證zukeeper服務

# telnet chavin.king 2181
Trying 192.168.72.130...
Connected to chavin.king.
Escape character is '^]'.
stat
Zookeeper version: 3.4.11-37e277162d567b55a07d1755f0b31c32e93c01a0, built on 11/01/2017 18:06 GMT

Zxid: 0x1a4

Connection closed by foreign host.

4、安裝zkui

git clone https://github.com/DeemOpen/zkui.git
cd zkui
mvn clean install

修改配置檔案預設值
#vim config.cfg
     serverPort=9090     #指定埠
     zkServer=192.168.1.110:2181
     sessionTimeout=300000

啟動程式至後臺
2.0-SNAPSHOT 會隨軟體的更新版本不同而不同，執行時請檢視target 目錄中真正生成的版本

nohup java -jar target/zkui-2.0-SNAPSHOT-jar-with-dependencies.jar &

用瀏覽器訪問：
http://chavin.king:9090/

5、安裝kafka

wget http://archive.apache.org/dist/kafka/1.1.0/kafka_2.11-1.1.0.tgz
tar -zxvf kafka_2.11-1.1.0.tgz -C /usr/local/kafka

mkdir -p /usr/local/kafka/data-logs

修改配置檔案 

vim server.properties

log.dirs=/usr/local/kafka/data-logs
zookeeper.connect=chavin.king:2181

啟動kafka

bin/kafka-server-start.sh -daemon config/server.properties &

建立topic

bin/kafka-topics.sh --create --zookeeper chavin.king:2181 --replication-factor 1 --partitions 1 --topic maxwell

檢視所有topic

bin/kafka-topics.sh --list --zookeeper chavin.king:2181

啟動producer

bin/kafka-console-producer.sh --broker-list chavin.king:9092 --topic maxwell

啟動consumer

bin/kafka-console-consumer.sh --zookeeper chavin.king:2181 --topic maxwell --from-beginning

或者

bin/kafka-console-consumer.sh --bootstrap-server chavin.king:9092  --from-beginning --topic maxwell

6、開啟mysql binlog

more /etc/my.cnf
[client]
default_character_set = utf8

[mysqld]
basedir = /usr/local/mysql-5.6.24
datadir = /usr/local/mysql-5.6.24/data
port = 3306
#skip-grant-tables
character_set_server = utf8
log_error = /usr/local/mysql-5.6.24/data/mysql.err

binlog_format = row
log-bin = /usr/local/mysql-5.6.24/logs/mysql-bin
sync_binlog = 2
max_binlog_size = 16M
expire_logs_days = 10

server_id = 1
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

7、安裝maxwell

wget https://github.com/zendesk/maxwell/releases/download/v1.16.0/maxwell-1.16.0.tar.gz
tar -zxvf maxwell-1.16.0.tar.gz -C /usr/local/maxwell

啟動maxwell

nohup bin/maxwell --user='canal' --password='canal' --host='chavin.king' --producer=kafka --kafka.bootstrap.servers=chavin.king:9092 > maxwell.log &

8、開發kafka消費程式

import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;

import java.util.Arrays;
import java.util.Properties;

public class KafkaTest {

    public static void main(String[] args){

        String topicName = "maxwell";
         String groupID = "example-group";

        Properties props = new Properties();
         props.put("bootstrap.servers","192.168.72.130:9092");
         props.put("group.id",groupID);
         props.put("auto.offset.reset","earliest");
         props.put("serializer.encoding","utf-8");
         props.put("key.deserializer","org.apache.kafka.common.serialization.StringDeserializer");
         props.put("value.deserializer","org.apache.kafka.common.serialization.StringDeserializer");

        KafkaConsumer<String,String > consumer = new KafkaConsumer<String, String>(props);
        
         consumer.subscribe(Arrays.asList(topicName));

        try{
             while(true){
                 ConsumerRecords<String,String> records = consumer.poll(1000);
             for (ConsumerRecord<String, String> record : records)
                 System.out.printf("offset = %d, key = %s, value = %s\n",
                         record.offset(), record.key(), record.value());
             }
         }finally{
             consumer.close();
         }
     }
}

ideal啟動以上消費程式

9、測試
