　　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）

    #判断命令是否执行成功

        echo "命令执行成功"
    fi
done

[yinzhengjie@s101 data]$ xrsync.sh /soft/kafka_2.11-1.1.0/

2>.分发环境变量

[yinzhengjie@s101 data]$ su
Password:
[root@s101 data]# xrsync.sh /etc/profile
=========== s102 %file ===========
命令执行成功
=========== s103 %file ===========
命令执行成功
=========== s104 %file ===========
命令执行成功
=========== s105 %file ===========
命令执行成功
[root@s101 data]# exit
exit
[yinzhengjie@s101 data]$ 

3>.修zk节点的改配置文件

[yinzhengjie@s102 ~]$ grep broker.id /soft/kafka/config/server.properties
broker.
[yinzhengjie@s102 ~]$ grep listeners /soft/kafka/config/server.properties | grep -v ^#
listeners=PLAINTEXT://s102:9092
[yinzhengjie@s102 ~]$ 

修改s102配置文件（/soft/kafka/config/server.properties）

[yinzhengjie@s103 ~]$ grep broker.id /soft/kafka/config/server.properties
broker.
[yinzhengjie@s103 ~]$  grep listeners /soft/kafka/config/server.properties | grep -v ^#
listeners=PLAINTEXT://s103:9092
[yinzhengjie@s103 ~]$
[yinzhengjie@s103 ~]$ 

修改s103配置文件（/soft/kafka/config/server.properties）

[yinzhengjie@s104 ~]$ grep broker.id /soft/kafka/config/server.properties
broker.
[yinzhengjie@s104 ~]$
[yinzhengjie@s104 ~]$ grep listeners /soft/kafka/config/server.properties | grep -v ^#
listeners=PLAINTEXT://s104:9092
[yinzhengjie@s104 ~]$ 

修改s104配置文件（/soft/kafka/config/server.properties）

4>.进入zookeeper客户端并删除zk的kafka节点数据

[yinzhengjie@s104 ~]$ zkCli.sh

5>.分别启动s102-s104的kafka

[yinzhengjie@s102 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties
[yinzhengjie@s102 ~]$ 

[yinzhengjie@s102 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties

[yinzhengjie@s103 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties
[yinzhengjie@s103 ~]$ 

[yinzhengjie@s103 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties

[yinzhengjie@s104 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties
[yinzhengjie@s104 ~]$ 

[yinzhengjie@s104 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties

6>.创建主题

[yinzhengjie@s104 ~]$ kafka-topics. --list
yinzhengjie
[yinzhengjie@s104 ~]$ 

查看以及有的主题（[yinzhengjie@s104 ~]$ kafka-topics.sh --zookeeper s102:2181 --list）

[yinzhengjie@s104 ~]$ kafka-topics. --create  --partitions  --replication-factor   --topic yzj
Created topic "yzj".
[yinzhengjie@s104 ~]$ 

创建主题（[yinzhengjie@s104 ~]$ kafka-topics.sh --zookeeper s104:2181 --create --partitions 2 --replication-factor 1 --topic yzj）

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. --topic yzj
>尹正杰到此一游！
>

[yinzhengjie@s102 ~]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties

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. --topic yzj --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].
尹正杰到此一游！

[yinzhengjie@s103 ~]$ kafka-console-consumer.sh --zookeeper s102:2181 --topic yzj --from-beginning

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！）

[yinzhengjie@s101 ~]$ more /usr/local/bin/xkafka.sh
#!/bin/bash

#判断用户是否传参
 ];then
    echo "无效参数，用法为: $0  {start|stop}"
    exit
fi

#获取用户输入的命令
cmd=$

 ; i<= ; i++ )) ; do
    tput setaf
    echo ========== s$i  $cmd ================
    tput setaf
    case $cmd in
        start)
            ssh s$i  "source /etc/profile ; kafka-server-start.sh -daemon /soft/kafka/config/server.properties"
            echo  s$i  "服务已启动"
            ;;
        stop)
            ssh s$i  "source /etc/profile ; kafka-server-stop.sh"
            echo s$i  "服务已停止"
            ;;
            *)
            echo "无效参数，用法为: $0  {start|stop}"
            exit
            ;;
     esac
done

[yinzhengjie@s101 ~]$ sudo chmod a+x /usr/local/bin/xkafka.sh
[yinzhengjie@s101 ~]$
[yinzhengjie@s101 ~]$ ll /usr/local/bin/xkafka.sh
