Canal使用入门服务端

编程

1.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

2.连接到数据库,执行如下语句:

[mysqld]

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。3.配置Canal的配置文件(conf/example/instance.properties),增加如下配置:

#数据库配置

canal.instance.master.address = 127.0.0.1:3306

canal.instance.master.journal.name =

canal.instance.master.position =

canal.instance.master.timestamp =

#主数据库

canal.instance.dbUsername = canal #帐号

canal.instance.dbPassword = canal #密码

canal.instance.defaultDatabaseName = #监听的数据库名称

canal.instance.connectionCharset = UTF-8 #字符集

#备份数据库(可以不配置)

#canal.instance.standby.address =

#canal.instance.standby.journal.name =

#canal.instance.standby.position =

#canal.instance.standby.timestamp =

4.执行启动文件(bin/startup.bat 或者 bin/startup.sh)。

5.检查日志:
logs/canal/canal.log

com.alibaba.otter.canal.deployer.CanalLauncher - ## start the canal server.

com.alibaba.otter.canal.deployer.CanalController - ## start the canal server[127.0.0.1:11111]

com.alibaba.otter.canal.deployer.CanalLauncher - ## the canal server is running now ......

logs/example/example.log

c.a.o.c.i.spring.support.PropertyPlaceholderConfigurer - Loading properties file from class path resource [canal.properties]

c.a.o.c.i.spring.support.PropertyPlaceholderConfigurer - Loading properties file from class path resource [example/instance.properties]

c.a.otter.canal.instance.spring.CanalInstanceWithSpring - start CannalInstance for 1-example 

c.a.otter.canal.instance.spring.CanalInstanceWithSpring - start successful....
