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
  1. [mysqld]
  2. log-bin=mysql-bin # 开启 binlog
  3. binlog-format=ROW # 选择 ROW 模式
  4. 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
  1. CREATE USER canal IDENTIFIED BY 'canal';  
  2. GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
  3. -- GRANT ALL PRIVILEGES ON *.* TO 'canal'@'%' ;
  4. 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
  1. wget https://github.com/alibaba/canal/releases/download/canal-1.0.17/canal.deployer-1.0.17.tar.gz
  • 解压缩
  1. mkdir /tmp/canal
  2. 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
  1. drwxr-xr-x 2 jianghang jianghang  136 2013-02-05 21:51 bin
  2. drwxr-xr-x 4 jianghang jianghang  160 2013-02-05 21:51 conf
  3. drwxr-xr-x 2 jianghang jianghang 1.3K 2013-02-05 21:51 lib
  4. drwxr-xr-x 2 jianghang jianghang   48 2013-02-05 21:29 logs
  • 配置修改
  1. vi conf/example/instance.properties
  1. ## mysql serverId
  2. canal.instance.mysql.slaveId = 1234
  3. #position info，需要改成自己的数据库信息
  4. canal.instance.master.address = 127.0.0.1:3306 
  5. canal.instance.master.journal.name = 
  6. canal.instance.master.position = 
  7. canal.instance.master.timestamp = 
  8. #canal.instance.standby.address = 
  9. #canal.instance.standby.journal.name =
  10. #canal.instance.standby.position = 
  11. #canal.instance.standby.timestamp = 
  12. #username/password，需要改成自己的数据库信息
  13. canal.instance.dbUsername = canal  
  14. canal.instance.dbPassword = canal
  15. canal.instance.defaultDatabaseName =
  16. canal.instance.connectionCharset = UTF-8
  17. #table regex
  18. 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
  1. sh bin/startup.sh
  • 查看 server 日志
  1. vi logs/canal/canal.log</pre>
