1、环境准备

[1.1 安装docker](#1.1 安装docker)

[1.2 安装Docker Compose](#1.2 安装Docker Compose)

2、docker-compose.yaml文件配置

3、system-config.properties文件配置

4、启动服务

1、环境准备

部署服务器的ip
可用的9093 9094 9095 2181端口
docker和docker-compose

1.1 安装docker

卸载旧版本（可选）

如果之前安装过旧版本的Docker，可以使用以下命令卸载：

bash 复制代码

sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine docker-ce

安装依赖

安装yum工具和相关依赖：

bash 复制代码

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

设置Docker仓库

添加Docker CE的官方yum仓库，为了更快的下载速度，可以使用国内的镜像源，例如阿里云：

bash 复制代码

sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

或者使用清华大学源：

bash 复制代码

sudo yum-config-manager --add-repo https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo

安装Docker CE

更新yum缓存并安装Docker CE：

bash 复制代码

sudo yum makecache fast  
sudo yum install -y docker-ce

启动Docker

启动Docker服务：

bash 复制代码

sudo systemctl start docker

验证Docker安装

可以通过运行以下命令来验证Docker是否成功安装：

bash 复制代码

sudo docker --version

1.2 安装Docker Compose

下载Docker Compose

使用curl命令从GitHub下载Docker Compose的二进制文件到/usr/local/bin/目录下（请检查版本是否最新）：

bash 复制代码

sudo curl -L "https://github.com/docker/compose/releases/download/v2.6.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

注意：上述命令中的版本号v2.6.0可能不是最新的，请访问Docker Compose的GitHub页面查看最新版本号。

赋予执行权限

为Docker Compose二进制文件赋予执行权限：

bash 复制代码

sudo chmod +x /usr/local/bin/docker-compose

验证Docker Compose安装

通过运行以下命令来验证Docker Compose是否成功安装：

bash 复制代码

docker-compose --version

2、docker-compose.yaml文件配置

文件内容如下：

bash 复制代码

version: '2'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    restart: always
    ports:
      - "2181:2181"
  kafka1:
    image: wurstmeister/kafka
    restart: always
    depends_on:
      - zookeeper
    ports:
      - "9093:9093"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: kafka1
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_LISTENERS: PLAINTEXT://:9093
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://192.168.202.219:9093
      KAFKA_BROKER_ID: 1
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  kafka2:
    image: wurstmeister/kafka
    restart: always
    depends_on:
      - zookeeper
    ports:
      - "9094:9094"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: kafka2
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_LISTENERS: PLAINTEXT://:9094
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://192.168.202.219:9094
      KAFKA_BROKER_ID: 2
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  kafka3:
    image: wurstmeister/kafka
    restart: always
    depends_on:
      - zookeeper
    ports:
      - 9095:9095
    environment:
      KAFKA_ADVERTISED_HOST_NAME: kafka3
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_LISTENERS: PLAINTEXT://:9095
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://192.168.202.219:9095
      KAFKA_BROKER_ID: 3
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  eagle:
    image: nickzurich/efak:3.0.1
    volumes: # 挂载目录
      - ./system-config.properties:/opt/efak/conf/system-config.properties
    environment: # 配置参数
      EFAK_CLUSTER_ZK_LIST: zookeeper:2181
    depends_on:
      - zookeeper
    ports:
      - "8048:8048"

修改文件中KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://192.168.202.219:9093的ip为服务器ip（有三处）

3、system-config.properties文件配置

bash 复制代码
