[](#%E5%87%86%E5%A4%87)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;

[](#%E5%90%AF%E5%8A%A8)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>

  • 查看 instance 的日志

    vi logs/example/example.log
