kafka 代码安装

15.安装kafka
cd /usr/local/
wget http://mirror.bit.edu.cn/apache/kafka/0.10.0.0/kafka_2.10-0.10.0.0.tgz
tar xf kafka_2.10-0.10.0.0.tgz
ln -s /usr/local/kafka_2.10-0.10.0.0 /usr/local/kafka
chown -R hdfs:hadoop /usr/local/kafka_2.10-0.10.0.0 /usr/local/kafka
chown -R root:root /usr/local/kafka_2.10-0.10.0.0 /usr/local/kafka

/usr/local/zookeeper/bin/zkCli.sh
create /kafka ''

vim /usr/local/kafka/config/server.properties
broker.id=0
zookeeper.connect=dev10.aoiplus.openpf:2181,dev06.aoiplus.openpf:2181,dev05.aoiplus.openpf:2181/kafka

scp -r /usr/local/kafka_2.10-0.10.0.0.tgz root@dev05.aoiplus.openpf:/usr/local/
scp -r /usr/local/kafka_2.10-0.10.0.0.tgz root@dev06.aoiplus.openpf:/usr/local/

scp -r /usr/local/kafka/config/server.properties root@dev05.aoiplus.openpf:/usr/local/kafka/config/server.properties
scp -r /usr/local/kafka/config/server.properties root@dev06.aoiplus.openpf:/usr/local/kafka/config/server.properties

master slave 启动
/usr/local/kafka/bin/kafka-server-start.sh /usr/local/kafka/config/server.properties &
创建topic
/usr/local/kafka/bin/kafka-topics.sh --create --zookeeper dev10.aoiplus.openpf:2181,dev06.aoiplus.openpf:2181,dev05.aoiplus.openpf:2181/kafka --replication-factor 3 --partitions 5 --topic baoy-topic
/usr/local/kafka/bin/kafka-topics.sh --describe --zookeeper dev10.aoiplus.openpf:2181,dev06.aoiplus.openpf:2181,dev05.aoiplus.openpf:2181/kafka --topic baoy-topic


/usr/local/kafka/bin/kafka-console-producer.sh --broker-list dev10.aoiplus.openpf:9092,dev05.aoiplus.openpf:9092,dev06.aoiplus.openpf:9092 --topic baoy-topic

/usr/local/kafka/bin/kafka-console-consumer.sh --zookeeper dev10.aoiplus.openpf:2181,dev05.aoiplus.openpf:2181,dev06.aoiplus.openpf:2181/kafka --from-beginning --topic baoy-topic

遇到的问题：

1. spring 中日志中的 logback 必须保持一致，这里我使用 org.slf4j 1.6.4

<groupId>org.slf4j</groupId>
			<artifactId>slf4j-api</artifactId>
			<version>1.6.4</version>
			<type>jar</type>
		</dependency>
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>slf4j-log4j12</artifactId>
			<version>1.6.4</version>
			<type>jar</type>
		</dependency>

2. hosts 问题，之前一直有连接连不同， zookeeper 使用 172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181 。是可以连通，但这不是我需要的，我需要的是172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181/kafka ，，

然后配置成172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181/kafka 就报错，怎么也不成功，之后配置172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181/kafka的时候发现是域名了，然后联不通，在本地添加 hosts　就可以解决该问题了。

3.使用 jar 包

  <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-kafka</artifactId>
            <version>1.3.0.RELEASE</version>
        </dependency>
