整合版canal ha搭建--基于1.1.4版本

news 来源：原创 2025/7/18 20:43:27

开启MySql Binlog
（1）修改MySql配置文件
（2）重启MySql服务,查看配置是否生效
（3）配置起效果后，创建canal用户，并赋予权限

安装canal-admin
（1）解压

canal.admin-1.1.4.tar.gz(36.8 MB)

（2）初始化元数据库
（3）启动canal-admin
（4）查看日志
（5）访问hadoop102 8089端口

（6）默认账号密码是admin /123456进行登录

（6）关闭cancal-admin
暂时先不要关，直接在页面上配置

canal-server安装
（1）上传解压，配置几台节点解压几个

canal.deployer-1.1.4.tar.gz(49.4 MB)

（2）修改配置canal_local.properties
/opt/apps/canal-server/conf/canal_local.properties
每台节点都要改
（3）每台节点启动canal
（4）查看ui界面上会自动注册节点，这个页面截图，之后会作对照

（5）先把所有server删除

（6）新建集群
填入名字和zookeeper集群地址

（7）配置集群节点统一配置

选择载入模板，修改配置如下

（8）把之前删除的server添加到集群中

集群：自己配的那个
其他的对照之前截图的填就可以

（9）配置instance
新建instance

修改配置，载入模板后修改配置如下

canal.instance.mysql.slaveId=1234 ---不能与mysql的server_id重复
canal.instance.master.address=192.168.6.32:3306 ----改为自己的地址
canal.instance.filter.regex=.*\\..* ----配置自己需要监控mysql的东西，我这里是所有库所有表
canal.mq.topic=canal ----未匹配规则的数据发往kafka的哪个topic
canal.mq.dynamicTopic=.*\\..* ---动态匹配规则发送到动态topic

canal.instance.filter.regex 、canal.mq.topic 和 canal.mq.dynamicTopic参数参照官网配置，我这里的配置只是样例。
保存
查看zookeeper

可以看到自己创建的集群和instance ha
