前提： 你服务器上已经安装并配置了java运行环境；
一、zookeeper安装 1、从zookeeper官网：http://zookeeper.apache.org/ 下载；我这里下载的是zookeeper-3.4.9.tar.gz; 2、解压到你安装目录:tar-zxvf zookeeper-3.4.9.tar.gz
二、zookeeper配置 1、修改zoo.cfg（直接复制zoo_sample.cfg）; 2、修改配置参数（集群模式）: tickTime=2000 dataDir=/mnt/zookeeper-3.4.9/data/ clientPort=2181 initLimit=5 syncLimit=2 server.1=broker1:2888:3888 server.2=broker2:2888:3888 server.3=broker3:2888:3888
3、修改zkEnv.sh，指定配置文件(这里为conf/zoo.cfg)
4、启动：
bin/zkServer.sh start 启动成功
三、kafka安装 1、从官网下载你需要的kafka：http://kafka.apache.org/downloads 2、接下到你安装目录：tar -zxvf kafka_2.11-1.1.0.tgz 四、kafka配置: broker.id=1 delete.topic.enable=true

五、启动kafka： bin/kafka-server-start.sh config/server.properties &
