本篇博客主要内容就是搭建Kafka完全分布式，它是在kafka本地模式（https://www.cnblogs.com/yinzhengjie/p/9209058.html）的基础之上进一步实现完全分布式搭建过程。
一.试验环境
试验环境共计4台服务器
1>.管理服务器（s101）
2>.Kafka节点二（s102，已经部署好了zookeeper服务）
3>.Kafka节点三（s103，已经部署好了zookeeper服务）
4>.Kafka节点四（s104，已经部署好了zookeeper服务）
二.kafka完全分布式部署
1>.将kafka加压后的安装包发送到其他节点（s102,s103,s104）

2>.分发环境变量

3>.修zk节点的改配置文件
[yinzhengjie@s102 ~]$ grep broker.id /soft/kafka/config/server.propertiesbroker.id=102[yinzhengjie@s102 ~]$ grep listeners /soft/kafka/config/server.properties | grep -v ^#listeners=PLAINTEXT://s102:9092[yinzhengjie@s102 ~]$
[yinzhengjie@s103 ~]$ grep broker.id /soft/kafka/config/server.propertiesbroker.id=103[yinzhengjie@s103 ~]$ grep listeners /soft/kafka/config/server.properties | grep -v ^#listeners=PLAINTEXT://s103:9092[yinzhengjie@s103 ~]$ [yinzhengjie@s103 ~]$
[yinzhengjie@s104 ~]$ grep broker.id /soft/kafka/config/server.propertiesbroker.id=104[yinzhengjie@s104 ~]$ [yinzhengjie@s104 ~]$ grep listeners /soft/kafka/config/server.properties | grep -v ^#listeners=PLAINTEXT://s104:9092[yinzhengjie@s104 ~]$
4>.进入zookeeper客户端并删除zk的kafka节点数据
[yinzhengjie@s104 ~]$ zkCli.sh Connecting to localhost:21812018-06-21 01:23:54,935 [myid:] - INFO [main:Environment@100] - Client environment:zookeeper.version=3.4.12-e5259e437540f349646870ea94dc2658c4e44b3b, built on 03/27/2018 03:55 GMT2018-06-21 01:23:54,938 [myid:] - INFO [main:Environment@100] - Client environment:host.name=s1042018-06-21 01:23:54,938 [myid:] - INFO [main:Environment@100] - Client environment:java.version=1.8.0_1312018-06-21 01:23:54,940 [myid:] - INFO [main:Environment@100] - Client environment:java.vendor=Oracle Corporation2018-06-21 01:23:54,940 [myid:] - INFO [main:Environment@100] - Client environment:java.home=/soft/jdk1.8.0_131/jre2018-06-21 01:23:54,940 [myid:] - INFO [main:Environment@100] - Client environment:java.class.path=/soft/zk/bin/../build/classes:/soft/zk/bin/../build/lib/*.jar:/soft/zk/bin/../lib/slf4j-log4j12-1.7.25.jar:/soft/zk/bin/../lib/slf4j-api-1.7.25.jar:/soft/zk/bin/../lib/netty-3.10.6.Final.jar:/soft/zk/bin/../lib/log4j-1.2.17.jar:/soft/zk/bin/../lib/jline-0.9.94.jar:/soft/zk/bin/../lib/audience-annotations-0.5.0.jar:/soft/zk/bin/../zookeeper-3.4.12.jar:/soft/zk/bin/../src/java/lib/*.jar:/soft/zk/bin/../conf:2018-06-21 01:23:54,940 [myid:] - INFO [main:Environment@100] - Client environment:java.library.path=/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib2018-06-21 01:23:54,940 [myid:] - INFO [main:Environment@100] - Client environment:java.io.tmpdir=/tmp2018-06-21 01:23:54,940 [myid:] - INFO [main:Environment@100] - Client environment:java.compiler=2018-06-21 01:23:54,940 [myid:] - INFO [main:Environment@100] - Client environment:os.name=Linux2018-06-21 01:23:54,941 [myid:] - INFO [main:Environment@100] - Client environment:os.arch=amd642018-06-21 01:23:54,941 [myid:] - INFO [main:Environment@100] - Client environment:os.version=3.10.0-327.el7.x86_642018-06-21 01:23:54,941 [myid:] - INFO [main:Environment@100] - Client environment:user.name=yinzhengjie2018-06-21 01:23:54,941 [myid:] - INFO [main:Environment@100] - Client environment:user.home=/home/yinzhengjie2018-06-21 01:23:54,941 [myid:] - INFO [main:Environment@100] - Client environment:user.dir=/home/yinzhengjie2018-06-21 01:23:54,942 [myid:] - INFO [main:ZooKeeper@441] - Initiating client connection, connectString=localhost:2181 sessionTimeout=30000 watcher=org.apache.zookeeper.ZooKeeperMain$MyWatcher@277050dcWelcome to ZooKeeper!JLine support is enabled2018-06-21 01:23:54,973 [myid:] - INFO [main-SendThread(localhost:2181):ClientCnxn$SendThread@1028] - Opening socket connection to server localhost/127.0.0.1:2181.

5>.分别启动s102-s104的kafka
[yinzhengjie@s102 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties[yinzhengjie@s102 ~]$
[yinzhengjie@s103 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties[yinzhengjie@s103 ~]$
[yinzhengjie@s104 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties[yinzhengjie@s104 ~]$
6>.创建主题
[yinzhengjie@s104 ~]$ kafka-topics.sh --zookeeper s102:2181 --listyinzhengjie[yinzhengjie@s104 ~]$
[yinzhengjie@s104 ~]$ kafka-topics.sh --zookeeper s104:2181 --create --partitions 2 --replication-factor 1 --topic yzjCreated topic "yzj".[yinzhengjie@s104 ~]$
7>.在任意zk节点开启控制台生产者（例如：在s102上）
[yinzhengjie@s102 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties[yinzhengjie@s102 ~]$ kafka-console-producer.sh --broker-list s104:9092 --topic yzj>尹正杰到此一游！>
8>.在任意zk节点开启控制台消费者（例如：在s103上）
[yinzhengjie@s103 ~]$ kafka-console-consumer.sh --zookeeper s102:2181 --topic yzj --from-beginningUsing 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].尹正杰到此一游！
三.编写kafka启动脚本（“/usr/local/bin/xkafka.sh”，别忘记添加执行权限，而且需要你提前配置好秘钥对哟！）
