详细资料可以参考maxwell官网 (mysql + maxwell + kafka + elasticsearch)
说明：本文主要是关于配置maxwell监听mysql的数据修改并实时将修改内容同步到kafka中。
- 配置mysql启用binlog
配置/etc/my.cnf,然后重启mysql服务
[mysqld]
server-id=1
log-bin=master
binlog_format=row
在mysql中给maxwell授予相应的权限并建立maxwell数据库
MariaDB [(none)]> GRANT ALL on maxwell.* to 'maxwell'@'%' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT SELECT, REPLICATION CLIENT, REPLICATION SLAVE on *.* to 'maxwell'@'%';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
建立一个测试用表，并插入一条数据
MariaDB [(none)]> use hivetest;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [hivetest]> insert into test set name = '11111', age = '12313';
Query OK, 1 row affected (0.00 sec)
- maxwell配置文件
[root@datanode1 ~]# cat /opt/maxwell-1.10.6/config.properties | grep -v ^# | grep -v ^$
log_level=info
producer=kafka
kafka.bootstrap.servers=192.168.190.11:9092,192.168.190.14:9092,192.168.190.17:9092
host=localhost
user=maxwell
password=123456
kafka_topic=test
kafka.compression.type=snappy
kafka.metadata.fetch.timeout.ms=5000
kafka.retries=3
kafka.acks=all
kinesis_stream=maxwell
启动maxwell测试下是否能正常获取binglog
[root@datanode1 maxwell-1.10.6]# bin/maxwell --user='maxwell' --password='123456' --host='127.0.0.1' --producer=stdout

ok,测试成功。
后台启动maxwell，并将数据发送到kafka(需要先在kafka中建好topic)
[root@datanode1 ~]# nohup bin/maxwell --user='maxwell' --password='123456' --host='127.0.0作者：观天坏笑
