# kafka单体安装 ### 下载并上传[安装包](https://archive.apache.org/dist/kafka/2.4.0/kafka_2.11-2.4.0.tgz) > 以`kafka_2.11-2.4.0.tgz`为例 ### 解压 ```shell tar -zxvf kafka_2.11-2.4.0.tgz -C /usr/local/ rm -rf kafka_2.11-2.4.0.tgz # 删除安装包 ``` ### 创建`log`目录 ```shell mkdir /usr/local/kafka_2.11-2.4.0/log ``` ### 修改配置文件 1. 修改监听端口 ```shell sed -i '/listeners=PLAINTEXT:\/\/:9092/alisteners=PLAINTEXT:\/\/:9092' /usr/local/kafka_2.11-2.4.0/config/server.properties ``` 2. 修改`log`目录 ```shell sed -i '/log.dirs=\/tmp\/kafka-logs/clog.dirs=\/usr\/local\/kafka_2.11-2.4.0\/log' /usr/local/kafka_2.11-2.4.0/config/server.properties ``` 3. 其他不用修改但要注意： ``` broker.id=0 # id唯一，集群时用得到。 zookeeper.connect=localhost:2181 # zookeeper客户端url ``` ### 启动kafka ```shell /usr/local/kafka_2.11-2.4.0/bin/kafka-server-start.sh /usr/local/kafka_2.11-2.4.0/config/server.properties ``` > 启动前先将`zookeeper`服务启动起来。
