在kafka connect 同步 mysql 主从数据库

下载以下文件,解压，放置到kafka的libs目录

kafka-connect-jdbc-4.1.1

从这里选择适合的MysqL connector

https://dev.MysqL.com/downloads/connector/j/

将里面的jar文件提取出来，也放到kafka的libs目录

在config目录下创建 connect-MysqL-source.properties

内容为

name=MysqL-jdbc-autoincrement
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.url=jdbc:MysqL://192.168.101.3:3306/tablename?user=xxx&password=xxx
mode=incrementing
incrementing.column.name=HeatMapId
topic.prefix=MysqL-jdbc-

注意更改jdbc的表名，用户名 密码

./kafka-server-start.sh ../config/server.properties &

bin/connect-standalone.sh config/connect-standalone.properties config/connect-MysqL-source.properties &

如果报

The server time zone value ” is  unrecognized or represents more than one time 。。。

以命令行进入MysqL

MysqL> show variables like '%time_zone%';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone |        |
| time_zone        | SYstem |
+------------------+--------+
2 rows in set

如果输出结果是system

设置time_zone即可

MysqL> set global time_zone='+8:00';
Query OK, 0 rows affected
