### 一、安装准备 ###

*  **下载`Kafka`：**[CentOS 7 下载 安装 Kafka][CentOS 7 _ _ Kafka]
 *  **安装`JDK`：**[CentOS 7 下载 安装 JDK][CentOS 7 _ _ JDK]

--------------------

### 二、`Kafka`单机模式 ###

#### A、创建`log`目录： ####

mkdir -p /data/data/kafka/log

#### B、修改`server.properties`配置文件 ####

`/data/opt/kafka_2.12-2.3.0/config/server.properties`

# kafka集群唯一标识
    broker.id=1
    # 端口号
    port=9092
    # 日志存放
    log.dirs=/data/data/kafka/log_1
    
    # zookeeper 地址和端口,多个地址 , 隔开
    # zookeeper.connect=127.0.0.1:2181,127.0.0.1:2182
    zookeeper.connect=127.0.0.1:2181
    
    # 可删除 topic
    delete.topic.enable=true

#### C、配置`Kafka`环境变量 ####

vim  /etc/profile

# Kafka环境变量
    export KAFKA_HOME=/data/opt/kafka_2.12-2.3.0
    export PATH=$KAFKA_HOME/bin:$PATH

#### D、`Kafka`环境变量生效 ####

source /etc/profile

#### E、运行`Kafka` ####

cd /data/opt/kafka_2.12-2.3.0
    
    nohup ./bin/kafka-server-start.sh ./config/server.properties &

#### F、测试`Kafka` ####

*  **创建`topic`**
    
        cd /data/opt/kafka_2.12-2.3.0
        
        ./bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testTopic
    
    ![在这里插入图片描述][20191016140026673.png]
 *  **查看`topic`列表**
    
        ./bin/kafka-topics.sh --list --zookeeper localhost:2181
    
    ![在这里插入图片描述][20191016140126697.png]
 *  **启动生产者**
    
        ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic testTopic
    
    ![在这里插入图片描述][2019101614025831.png]
 *  **启动消费者**
    
        ./bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic testTopic
    
    ![在这里插入图片描述][20191016140328719.png]
 *  **测试生产者消费者**
