5.修改instance.properties 

      a.配置MySQL的配置文件(my.ini),增加如下配置:

[mysqld]
log-bin=mysql-bin #开启日志监控
binlog-format=ROW #监控模式为ROW
server_id=1 #配置mysql replaction需要定义,不能和canal的slaveId重复

 

      b. 连接到数据库,执行如下语句:        

CREATE USER canal IDENTIFIED BY 'canal'; 
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
-- GRANT ALL PRIVILEGES ON *.* TO 'canal'@'%' ;
FLUSH PRIVILEGES;

         备注:Canal的原理是模拟自己为MySQL Slave,所以这里一定需要做为MySQL Slave的相关权限

     c.进入到/home/iflytekde/canal/conf/example找到instance.properties

#################################################

 

6.执行启动或停止

启动/home/test/canal/bin/startup.bat 或者 bin/startup.sh

停止/home/test/canal/bin/stop.bat 或者 bin/ stop.sh

 

注意:停止后需要删除以下文件/home/test/canal/conf/example/meta.dat文件和/home/test/canal/logs下面的文件
