centos install kafka and zookeeper

1.安装zookeeper

ZooKeeper is a distributed, open-source coordination service for distributed applications.
1.下载
　　wget http://apache.fayea.com/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz
2.解压复制
　　sudo mv zookeeper-3.3.6 /var/

3.编辑配置文件
　　在/var/zookeeper-3.3.6 下面的conf 里面有一个zoo_sample.cfg 复制一个zoo.cfg 然后编辑内容。我这里是都放在/var/data/下的 所以配置是这样的
　　

# The number of milliseconds of each tick
tickTime=
# The number of ticks that the initial
# synchronization phase can take
initLimit=
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=
# the directory where the snapshot is stored.
dataDir=/var/data/zookeeper
# the port at which the clients will connect
clientPort=

在此之前在先新建文件夹以及权限设置这种

　4.启动

　　进入到bin目录 执行./zkServer.sh start

　　然后ps-ef|grep zoo能看到进程说明已经启动成功

　5.测试

　　在bin目录下执行./zkCli.sh -server 127.0.0.1 然后下面会出现一堆日志信息

　　正常的是这样的

到这里zookeeper就安装结束了有什么不明白的可以去官网看看.这个是独立安装 也可以用kafka里面的那个

2.安装kafka

　1.下载

　　 wget http://apache.fayea.com/kafka/0.10.1.0/kafka_2.10-0.10.1.0.tgz

惯例解压然后复制

　　tar -xvf kafka_2.10-0.10.1.0

　　mv kafka_2.10-0.10.1.0 /var/

2.编辑配置文件

　　在kafka下面执行

　　vi bin/kafka-server-start.sh  默认

　　export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G" 我用的是这个 ，根据大家的配置自己配置就可以了 

　3.启动

　　bin/kafka-server-start.sh config/server.properties &

　4.测试

　　1.新建topic

　　　　bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

　　2.查看新建的topic

　　　　bin/kafka-topics.sh --list --zookeeper localhost:2181

　　3.使用刚才新建的topic 新建一个消息

　　　　bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test

　　　　然后就可以输入了

　　　　我随便输入的hello 1212121

　　4.再开一个终端 执行bin下面的

　　　　bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning

　　　　会看到输入的信息，至此全部完成。关于客户端的用法会在接下来的文章里出现
