maxwell主要提供了下列功能
支持 SELECT * FROM table 的方式进行全量数据初始化
支持在主库发生failover后,自动回复binlog位置(GTID)
可以对数据进行分区,解决数据倾斜问题,发送到kafka的数据支持database,table,column等级别的数据分区
工作方式是伪装为Slave,接受binlog events, 然后根据schemas信息拼装,可以接受ddl、xid、row等各种event
1.首先配置mysql 启用binlog (因为我们没有mysql设置的权限, 只需要让运维帮忙打开maxwell权限即可)
$ vi my.cnf
[mysqld]
server_id=1
log-bin=master
binlog_format=row
2.创建一个yzq.properties文件
log_level=INFO
producer=kafka
host = 120.27.208.185 //mysql数据库的URL
user = maxwell //就固定值
password = 123456 //密码
producer_ack_timeout = 600000

3.执行----- bin/maxwell --config yzq.properties
即可
