1.首先安裝并啟動mysql

mysql5.7版本安裝部署詳細步驟_怪只怪滿眼盡是人間煙火-CSDN博客最新版mysql下載地址：MySQL :: Download MySQL Community Server現在的服務器應該都支持64位了，下載64位即可1.首先新建文件夾，并進入該文件夾，將下載好的mysql文件上傳至此文件夾，mkdir local && cd local2.解壓及創建目錄tar -zxvf mysql-5.7.36-linux-glibc2.12-x86_64.tar.gzmv mysql-5.7.36-linux-glibc2...https://blog.csdn.net/weixin_38959210/article/details/122051301注意mysql的配置文件必須開啟日志

# 一般情況下，Window修改mysql目錄下的my.ini # 一般情況下，Linux修改/etc/mysql下的my.cnf[mysqld] # 添加的部分，server-id隨便填 server-id = 12345 log-bin = mysql-bin # 必須為ROW binlog_format = ROW # 必須為FULL，MySQL-5.7后才有該參數 binlog_row_image = FULL expire_logs_days = 10

2.然后安裝并啟動kafka

linux單機版kafka啟動命令_怪只怪滿眼盡是人間煙火-CSDN博客需要java環境，推薦1.8以上下載kafka，解壓，進入kafka的bin目錄啟動zookeeper（Kafka 0.5.x版本以上已經自帶ZooKeper）自測的話直接使用自帶的zookeeper就行，要是生產的話，建議分離。nohup ./zookeeper-server-start.sh ../config/zookeeper.properties &啟動kafkanohup ./kafka-server-start.sh ../config/server....https://qushen.blog.csdn.net/article/details/122682000

3.安裝并配置canal
canal.deployer-1.1.5.tar.gz??????https://github.com/alibaba/canal/releases/download/canal-1.1.5/canal.deployer-1.1.5.tar.gz

配置兩個文件

啟動canal

?/bin/startup.sh

?kafka消費者可以實時監聽到數據庫變化。

以上 JSON 數據的字段解釋如下：

字段類型說明

id	Number	TiCDC 默認值為 0
database	String	Row 所在的 Database 的名字
table	String	Row 所在的 Table 的名字
pkNames	Array	組成 primary key 的所有列的名字
isDdl	Bool	該條消息是否為 DDL 事件
type	String	Canal-JSON 定義的事件類型
es	Number	產生該條消息的事件發生時的 13 位（毫秒級）時間戳
ts	Number	TiCDC 生成該條消息時的 13 位（毫秒級）時間戳
sql	String	當 isDdl 為 true 時，記錄對應的 DDL 語句
sqlType	Object	當 isDdl 為 false 時，記錄每一列數據類型在 Java 中的類型表示
mysqlType	object	當 isDdl 為 false 時，記錄每一列數據類型在 MySQL 中的類型表示
data	Object	當 isDdl 為 false 時，記錄每一列的名字及其數據值
old	Object	僅當該條消息由 Update 類型事件產生時，記錄每一列的名字，和 Update 之前的數據值
_tidb	Object	TiDB 擴展字段，僅當?enable-tidb-extension?為 true 時才會存在。其中的?commitTs?值為造成 Row 變更的事務的 TSO
