## 1.拷贝文件到指定目录下 ##

mkdir /home/test/canal

## 2.解压缩 ##

tar zxvf canal.deployer-1.0.0.tar.gz

## 3.对文件canal文件夹进行授权 ##

chmod –R 777 canal

## 4.修改配置canal.properties ##

a.进入到/home/test/canal/conf找到canal.properties

## 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

    ## mysql serverId , v1.0.26+ will autoGen
    # canal.instance.mysql.slaveId=0

    # table regex
    canal.instance.filter.regex=test1\\..*                                 #正则匹配默认.*\\..*，其中前面.*代表库名，后面.*代表表名
    # table black regex
    canal.instance.filter.black.regex=
    #################################################

## 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
