准备

  • 对于自建 MySQL , 需要先开启 Binlog 写入功能,配置 binlog-format 为 ROW 模式,my.cnf 中配置如下

    [mysqld]
    log-bin=mysql-bin # 开启 binlog
    binlog-format=ROW # 选择 ROW 模式
    server_id=1 # 配置 MySQL replaction 需要定义,不要和 canal 的 slaveId 重复
    
    • 注意:针对阿里云 RDS for MySQL , 默认打开了 binlog , 并且账号默认具有 binlog dump 权限 , 不需要任何权限或者 binlog 设置,可以直接跳过这一步
  • 授权 canal 链接 MySQL 账号具有作为 MySQL slave 的权限, 如果已有账户可直接 grant

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

启动

  • 下载 canal, 访问 release 页面 , 选择需要的包下载, 如以 1.0.17 版本为例

    wget https://github.com/alibaba/canal/releases/download/canal-1.0.17/canal.deployer-1.0.17.tar.gz
  • 解压缩

    mkdir /tmp/canal
    tar zxvf canal.deployer-$version.tar.gz  -C /tmp/canal
    
    • 解压完成后,进入 /tmp/canal 目录,可以看到如下结构
      drwxr-xr-x 2 jianghang jianghang  136 2013-02-05 21:51 bin
      drwxr-xr-x 4 jianghang jianghang  160 2013-02-05 21:51 conf
      drwxr-xr-x 2 jianghang jianghang 1.3K 2013-02-05 21:51 lib
      drwxr-xr-x 2 jianghang jianghang   48 2013-02-05 21:29 logs
      
  • 配置修改

    vi conf/example/instance.properties
    
    ## mysql serverId
    canal.instance.mysql.slaveId = 1234
    #position info,需要改成自己的数据库信息
    canal.instance.master.address = 127.0.0.1:3306 
    canal.instance.master.journal.name = 
    canal.instance.master.position = 
    canal.instance.master.timestamp = 
    #canal.instance.standby.address = 
    #canal.instance.standby.journal.name =
    #canal.instance.standby.position = 
    #canal.instance.standby.timestamp = 
    #username/password,需要改成自己的数据库信息
    canal.instance.dbUsername = canal  
    canal.instance.dbPassword = canal
    canal.instance.defaultDatabaseName =
    canal.instance.connectionCharset = UTF-8
    #table regex
    canal.instance.filter.regex = .\*\\\\..\*
    • canal.instance.connectionCharset 代表数据库的编码方式对应到 java 中的编码类型,比如 UTF-8,GBK , ISO-8859-1
    • 如果系统是1个 cpu,需要将 canal.instance.parser.parallel 设置为 false
  • 启动

    sh bin/startup.sh
    
  • 查看 server 日志

    vi logs/canal/canal.log</pre>
    
    2013-02-05 22:45:27.967 [main] INFO  com.alibaba.otter.canal.deployer.CanalLauncher - ## start the canal server.
    2013-02-05 22:45:28.113 [main] INFO  com.alibaba.otter.canal.deployer.CanalController - ## start the canal server[10.1.29.120:11111]
    2013-02-05 22:45:28.210 [main] INFO  com.alibaba.otter.canal.deployer.CanalLauncher - ## the canal server is running now ......
    
  • 查看 instance 的日志

    vi logs/example/example.log
    
    2013-02-05 22:50:45.636 [main] INFO  c.a.o.c.i.spring.support.PropertyPlaceholderConfigurer - Loading properties file from class path resource [canal.properties]

  • 关闭

    sh bin/stop.sh
