kafka 安装配置

1.在服务器安装 java

2.配置一套zookeeper集群
我在该服务器配置了一套数量为3的伪zookeeper集群
zoo1 对应 2181端口
zoo2 对应 2182端口
zoo3 对应 2183端口
（如果不想做集群，可以临时启用一个 zookeeper模拟实例）

3.上传 kafka_2.12-1.1.0.tgz
解压
# tar -zxvf kafka_2.12-1.1.0.tgz

4.修改配置文件
# cd kafka_2.12-1.1.0/config
# vi server.properties

红字是我本机伪zookeeper集群地址

############################# Zookeeper #############################

# Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.
#zookeeper.connect=localhost:2181

zookeeper.connect=localhost:2181,localhost:2182,localhost:2183

# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=6000

5.启动 kafka
# cd kafka_2.12-1.1.0
# bin/kafka-server-start.sh config/server.properties

后台启动方式：

cd kafka_2.12-1.1.0/bin
nohup ./kafka-server-start.sh ../config/server.properties 1>/dev/null 2>&1 &
