一、官网地址：[https://github.com/alibaba/canal][https_github.com_alibaba_canal]

二、安装 canal server

1. 下载canal

直接下载

访问：[https://github.com/alibaba/canal/releases][https_github.com_alibaba_canal_releases] ，会列出所有历史的发布版本包 下载方式，比如以1.0.24版本为例子

下载：[https://github.com/alibaba/canal/releases/download/canal-1.0.24/canal.deployer-1.0.24.tar.gz][https_github.com_alibaba_canal_releases_download_canal-1.0.24_canal.deployer-1.0.24.tar.gz]

![70][]

2. 解压缩

mkdir canal
    tar zxvf canal.deployer-$version.tar.gz

解压完成后，进入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

3. 配置修改

应用参数：

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\_test canal.instance.connectionCharset = UTF-8

# table regex #

canal.instance.filter.regex = .*\\..*

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

说明：

*  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

4. 准备启动

sh bin/startup.sh

5. 查看日志

vi logs/canal/canal.log

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 ......

具体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]
    2013-02-05 22:50:45.641 [main] INFO  c.a.o.c.i.spring.support.PropertyPlaceholderConfigurer - Loading properties file from class path resource [example/instance.properties]
    2013-02-05 22:50:45.803 [main] INFO  c.a.otter.canal.instance.spring.CanalInstanceWithSpring - start CannalInstance for 1-example 
    2013-02-05 22:50:45.810 [main] INFO  c.a.otter.canal.instance.spring.CanalInstanceWithSpring - start successful....

6. 关闭

sh bin/stop.sh

三、配置mysql

a. canal的原理是基于mysql binlog技术，所以这里一定需要开启mysql的binlog写入功能，建议配置binlog模式为row.

修改my.cnf配置文件，如果找不到，参考：[https://blog.csdn.net/bahaidong/article/details/80475684][https_blog.csdn.net_bahaidong_article_details_80475684]

[mysqld]
    log-bin=mysql-bin #添加这一行就ok
    binlog-format=ROW #选择row模式
    server_id=1 #配置mysql replaction需要定义，不能和canal的slaveId重复

b. 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.

用root账户登录mysql添加

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

针对已有的账户可直接通过grant

四、测试数据库脚本

create database canal\_test;

use canal\_test;

CREATETABLE\`student\` (

\`id\` int(11) NOT NULL AUTO\_INCREMENT,

\`name\`varchar(100) DEFAULTNULL,

\`weight\`varchar(100) DEFAULTNULL,

PRIMARYKEY (\`id\`)

) ENGINE=InnoDB AUTO\_INCREMENT=6 DEFAULT CHARSET=utf8;

五、下载示例代码

[https://github.com/alibaba/canal/releases/download/canal-1.0.24/canal.example-1.0.24.tar.gz  
][https_github.com_alibaba_canal_releases_download_canal-1.0.24_canal.example-1.0.24.tar.gz]

导入idea或eclipse

六、单机模式运行

启动canal，找到类，运行即可，修改表数据即可

SimpleCanalClientTest

七、集群模式

1、安装zookeeper

通过docker安装一台测试用即可

docker用法参考：[https://blog.csdn.net/bahaidong/article/details/80467584][https_blog.csdn.net_bahaidong_article_details_80467584]

启动zookeeper

$ docker run \-d\-p 80:80 \--name zookeeper zookeeper

停止 $ docker container stop zookeeper

删除 $ docker container rm zookeeper

重启 $ docker container start zookeeper

2、运行，修改表数据即可

ClusterCanalClientTest
