1、安装zookeeper
# 解压缩 [root@localhost zookeeper]# tar -zxvf zookeeper-3.4.12.tar.gz [root@localhost zookeeper]# mv zookeeper-3.4.12 zk_simple
# 复制zoo_simple.cfg到zoo.cfg [root@localhost zookeeper]# cd zk_simple/ [root@localhost zk_simple]# cp conf/zoo_sample.cfg conf/zoo.cfg -R
# 启动 [root@localhost zk_simple]# bin/zkServer.sh start ZooKeeper JMX enabled by default Using config: /mirana/software/zookeeper/zk_simple/bin/../conf/zoo.cfg Starting zookeeper ... STARTED
# 查看zookeeper启动状态 [root@localhost zk_simple]# bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /mirana/software/zookeeper/zk_simple/bin/../conf/zoo.cfg Mode: standalone
2、安装kafka
2.1下载并上传kafka_2.12-1.1.0.tgz
2.2解压
[root@localhost software]# tar -zxvf kafka_2.12-1.1.0.tgz [root@localhost software]# mv kafka_2.12-1.1.0 kafka2.12/ [root@localhost software]# cd kafka2.12/ [root@localhost kafka2.12]# ll 总用量 52 drwxr-xr-x. 3 root root 4096 3月 24 06:55 bin drwxr-xr-x. 2 root root 4096 3月 24 06:55 config drwxr-xr-x. 2 root root 4096 5月 26 14:29 libs -rw-r--r--. 1 root root 28824 3月 24 06:51 LICENSE drwxr-xr-x. 2 root root 4096 5月 26 15:06 logs -rw-r--r--. 1 root root 336 3月 24 06:51 NOTICE drwxr-xr-x. 2 root root 44 3月 24 06:55 site-docs
2.3 【单节点单代理模式】启动kafka服务端，新开窗口用于持续打印kafka服务端的日志【窗口1】
后台启动，将所有的日志推送到linux黑洞
[root@localhost kafka2.12]# bin/kafka-server-start.sh config/server.properties >>/dev/null 2>&1 &
正常启动后当前窗口作为服务端的日志输出窗口

2.5 重新打开一个窗口，用于查看订阅者收到的消息【窗口2】
[root@localhost kafka2.12]# bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic mytopic01 --from-beginning Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].
在先前的窗口模拟生产者生产消息，这里生产三条消息
[root@localhost kafka2.12]# bin/kafka-console-producer.sh --broker-list localhost:9092 --topic mytopic01 >my first msg
>my second msg
>my third msg >
订阅者窗口【窗口2】打印日志如下：
[root@localhost kafka2.12]# bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic mytopic01 --from-beginning Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release.

3、单节点多代理模式
3.1 创建多个kafka brokers
复制server.properties到server1.properties,server2.properties,server3.properties，修改配置如下
# server1.properties
broker.id=1
port=9091
log.dirs=/tmp/kafka1-logs
# server2.properties
broker.id=2
port=9092
log.dirs=/tmp/kafka2-logs
# server3.properties
broker.id=3
port=9093
log.dirs=/tmp/kafka3-logs
3.2 启动三个kafka代理（不启动server.properties，启动sever1.properties，server2.properties，server3.properties）
[root@localhost kafka2.12]# bin/kafka-server-start.sh config/server1.properties [root@localhost kafka2.12]# bin/kafka-server-start.sh config/server2.properties [root@localhost kafka2.12]# bin/kafka-server-start.sh config/server3.properties
查看zookeeper和kafka的进程，其中QuorumPeerMain是zookeeper的守护进程，三个kafka分别对应kafka的代理进程
[root@localhost kafka2.12]# jps 3923 Kafka 2808 QuorumPeerMain 4505 Kafka 4202 Kafka 8426 Jps

【Multibrokerapplication01】订阅的消息如下
[root@localhost kafka2.12]# bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic Multibrokerapplication01 --from-beginning
Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].
