Maxwell读取MySQL binlog日志到Kafka

启动MySQL

创建maxwell的数据库和用户

在MySQL中创建一个测试数据库和表

前面三个步骤详见 Maxwell读取MySQL binlog日志通过stdout展示

启动Zookeeper

[hadoop@hadoop001 ~]$ cd $ZK_HOME/bin [hadoop@hadoop001 bin]$ ./zkServer.sh start

启动kafka，并创建主题为maxwell的topic

[hadoop@hadoop001 bin]$ cd $KAFKA_HOME //查看kafka版本，防止maxwell不支持 [hadoop@hadoop001 kafka]$ find ./libs/ -name \*kafka_\* | head -1 | grep -o '\kafka[^\n]*' kafka_2.11-0.10.0.1-sources.jar //启动kafka-server服务 [hadoop@hadoop001 kafka]$ nohup bin/kafka-server-start.sh config/server.properties & [hadoop@hadoop001 kafka]$ jps 13460 QuorumPeerMain 14952 Jps 13518 Kafka [hadoop@hadoop001 kafka]$ bin/kafka-topics.sh --create --zookeeper 192.168.137.2:2181/kafka --replication-factor 1 --partitions 3 --topic maxwell Created topic "maxwell". [hadoop@hadoop001 kafka]$ bin/kafka-topics.sh --list --zookeeper 192.168.137.2:2181/kafka __consumer_offsets maxwell

启动kafaka的消费者，检查数据是否到位

[hadoop@hadoop001 kafka]$ bin/kafka-console-consumer.sh --zookeeper 192.168.137.2:2181/kafka --topic maxwell --from-beginning

启动maxwell进程
