cancel框架同步mysql数据到kafka

1、下载cancel

https://github.com/alibaba/canal/releases/tag/canal-1.1.5

2、修改conf文件夹下的canal.properties配置文件

canal.zkServers=localhost:2181
canal.serverMode = kafka
##################################################
######### 		     Kafka 		     #############
##################################################
kafka.bootstrap.servers = localhost:9092

3、修改conf/example文件夹下的instance.properties配置文件
在sql查询show binary logs语句得到binlog日志

canal.instance.master.address= localhost:3306
canal.instance.master.journal.name=mysql-bin.000001
canal.instance.master.position=156

# username/password
canal.instance.dbUsername=xxxx
canal.instance.dbPassword=xxxxx
canal.instance.filter.regex=db_mybatis.userProject #数据库名.表名，可多个
canal.mq.topic=canceltopic   #消息队列的topic

4、启动
在bin目录下执行

./startup.sh

启动程序
注：MySQL需要创建新用户

mysql> CREATE USER canal IDENTIFIED BY '123456'; 
mysql> GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';  
mysql> FLUSH PRIVILEGES;
mysql> show grants for 'canal' ;
