《数据同步-Maxwell系列》maxwell订阅MySQL的binlog日志并生产到Kafka传输数据 2.Canal只能抓取最新数据，对已存在的历史数据没有办法处理。Maxwell提供一个bootstrap功能，可以直接引导出完整的历史数据用于初始化。1.Canal有server+client模式，Maxwell只有一个server把数据发送到消息队列或redis。4.Canal在server+client模式下，可以自定义数据格式。3.Maxwell不支持HA，需要自行开发。但支持断电还原，即错误解决后重启继续上次位置读取数据。6.Maxwell需要在数据库中建立Maxwell库。阅读详情

启动MySQL

创建maxwell的数据库和用户

在MySQL中创建一个测试数据库和表

前面三个步骤详见 Maxwell读取MySQL binlog日志通过stdout展示

启动Zookeeper

[hadoop@hadoop001 ~]$ cd $ZK_HOME/bin
[hadoop@hadoop001 bin]$ ./zkServer.sh start

启动kafka，并创建主题为maxwell的topic

[hadoop@hadoop001 bin]$ cd $KAFKA_HOME
//查看kafka版本，防止maxwell不支持
[hadoop@hadoop001 kafka]$ find ./libs/ -name \*kafka_\* | head -1 | grep -o '\kafka[^\n]*'
kafka_2.11-0.10.0.1-sources.jar
//启动kafka-server服务
[hadoop@hadoop001 kafka]$ nohup bin/kafka-server-start.sh config/server.properties &
[hadoop@hadoop001 kafka]$ jps
13460 QuorumPeerMain
14952 Jps
13518 Kafka
[hadoop@hadoop001 kafka]$ bin/kafka-topics.sh --create --zookeeper 192.168.137.2:2181/kafka --replication-factor 1 --partitions 3 --topic maxwell
Created topic "maxwell".
[hadoop@hadoop001 kafka]$ bin/kafka-topics.sh --list --zookeeper 192.168.137.2:2181/kafka
__consumer_offsets
maxwell

启动kafaka的消费者，检查数据是否到位

[hadoop@hadoop001 kafka]$ bin/kafka-console-consumer.sh --zookeeper 192.168.137.2:2181/kafka --topic maxwell --from-beginning

启动maxwell进程

//先检查maxwell是否支持kafka-0.10.0.1
[root@hadoop000 ~]# cd /root/app/maxwell-1.17.1/lib/kafka-clients
[root@hadoop001 kafka-clients]# ll

//发现支持kafka-0.10.0.1版本，假如没有生产上正在用的kafka版本的jar包，可以直接把这个版本的client jar包copy进来

Maxwell的过滤功能

参考过滤配置： <http://maxwells-daemon.io/filtering/>;

[root@hadoop001 maxwell-1.17.1]# bin/maxwell --user='maxwell' --password='maxwell' \
--host='127.0.0.1' --filter 'exclude: *.*, include:hlwtest.emp1' \
--producer=kafka --kafka_version=0.10.0.1 --kafka.bootstrap.servers=192.168.137.2:9092 --kafka_topic=maxwell
--filter 'exclude: *.*, include:hlwtest.emp1'的意思是只监控hlwtest.emp1表的变化，其他的都不监控
//MySQL中update数据
mysql> update emp set sal=730 where empno=6001;
mysql> update emp1 set sal=330 where empno=6001;
mysql> update emp set sal=730 where empno=6001;
mysql> update emp1 set sal=331 where empno=6001;

//Kafka消费者接收到的数据
{"database":"hlwtest","table":"emp1","type":"update","ts":1552099858,"xid":916,"commit":true,"data":{"empno":6001,"ename":"SIWA","job":"DESIGNER","mgr":7001,"hiredate":"2019-03-08 00:00:00","sal":330.00,"comm":6000.00,"deptno":40},"old":{"sal":321.00}}

确实只消费到了emp1表的update语句，而没有接收到emp表的更新
