使用 Docker Compose 一键安装 novel 项目的开发环境

背景

novel 项目的技术栈比较多，很多同学都曾经向我反映过安装完全部环境需要花大量时间，甚至有的小伙伴可能嫌麻烦就直接放弃了，为了解决这个问题，今天花了好几个小时整了个一键安装的教程，不仅可以一键安装所有 novel 项目技术栈所需的环境，而且也可以直接用于其它的项目中。为什么搞了这么长时间呢？主要是在 Elasticsearch 8 上面踩了一些坑，下面先看下效果：

安装步骤

1.Docker Compose 安装（除了第一步要根据自己的系统来安装，其它步骤全都一样）

如果是 Ubuntu 系统，执行如下的安装命令：

sudo apt install docker-compose -y

查看 Docker Compose 和 Docker 的版本信息：

docker-compose version
docker --version
docker version

2.准备 Docker Compose 的服务编排文件

version: '3.9'
services:
  novel-MySQL:
    contAIner_name: novel-mysql
    image: mysql:8.0
    restart: always
    hostname: novel-mysql
    environment:
      - MYSQL_ROOT_PASSword=test123456
    volumes:
      - "/data/docker/mysql/data:/var/lib/mysql"
      - "/data/docker/mysql/init.sql:/docker-entrypoint-initdb.d/init.sql"
    command: mysqld --max_allowed_packet=100M
    ports:
      - 3306:3306
   .NETworks:
      - novelnet


  novel-redis:
    container_name: novel-redis
    image: redis:7.0
    restart: always
    hostname: novel-redis
    command: redis-server --save 60 1 --loglevel warning
    ports:
      - 6379:6379
    networks:
      - novelnet


  novel-rabbitmq:
    container_name: novel-rabbitmq
    image: rabbitmq:3-management
    restart: always
    hostname: novel-rabbitmq
    environment:
      - RABBITMQ_DEFAULT_USER=xxyopen
      - RABBITMQ_DEFAULT_PASS=test123456
    ports:
      - 15672:15672
      - 5672:5672
    networks:
      - novelnet


  novel-elasticsearch:
    container_name: novel-elasticsearch
    image: elasticsearch:8.6.2
    restart: always
    hostname: novel-elasticsearch
    environment:
    # 内存不够用的话最好不要配置这个
    # - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.type=single-node
    # 挂载本地目录时需要修改该目录的读写权限才能正常启动
    # volumes:
    #   - /data/docker/elasticsearch/data:/usr/share/elasticsearch/data
    #   - /data/docker/elasticsearch/logs:/usr/share/elasticsearch/logs
    ports:
      - 9200:9200
      - 9300:9300
    networks:
      - novelnet


  novel-kibana:
    container_name: novel-kibana
    image: kibana:8.6.2
    restart: always
    hostname: novel-kibana
    environment:
      ELASTICSEARCH_HOSTS: '["https://novel-elasticsearch:9200"]'
    volumes:
      - /data/docker/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml
    ports:
      - 5601:5601
    depends_on:
      - novel-elasticsearch
    networks:
      - novelnet


  novel-xxl-job-admin:
    container_name: novel-xxl-job-admin
    image: xuxueli/xxl-job-admin:2.3.1
    restart: always
    hostname: novel-xxl-job-admin
    environment:
      - PARAMS=--spring.datasource.url=jdbc:mysql://novel-mysql:3306/xxl_job?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai --spring.datasource.username=root --spring.datasource.password=test123456
      - JAVA_OPTS=-Xmx512m
    volumes:
      - /data/docker/xxl-job-admin/data/Applogs:/data/applogs
    ports:
      - 8080:8080
    depends_on:
      - novel-mysql
    networks:
      - novelnet


networks:
  novelnet:
    driver: bridge

注意：Elasticsearch 容器挂载本地目录或文件时，需要修改目录或文件的读写权限，否则启动不成功。官方原文如下：

If you are bind-mounting a local directory or file, it must be readable by the elasticsearch user. In addition, this user must have write access to the data and log dirs. A good strategy is to grant group access to gid 1000 or 0 for the local directory.

For example, to prepare a local directory for storing data through a bind-mount:

mkdir esdatadir
chmod g+rwx esdatadir
chgrp 1000 esdatadir

3.在后台运行所有编排文件中的容器

sudo docker-compose up -d

4.重设 kibana_system 账户的密码，kibana_system 是用于连接到 Elasticsearch 的内置角色，它不能用于登录 kibana 控制台

 sudo docker exec -it novel-elasticsearch bin/elasticsearch-reset-password --username kibana_system

5.创建 kibana.yml 配置文件，填入上一步重置的 kibana_system 账户和密码

sudo mkdir -p /data/docker/kibana/config && sudo touch /data/docker/kibana/config/kibana.yml && sudo chmod 666 /data/docker/kibana/config/kibana.yml && sudo echo 'server.host: "0.0.0.0"
server.shutdownTimeout: "5s"
elasticsearch.hosts: [ "https://novel-elasticsearch:9200" ]
elasticsearch.ssl.verificationMode: "none"
elasticsearch.username: "kibana_system"
elasticsearch.password: "=5Jbb-VsW9TkY*cJu9Y4"
' > /data/docker/kibana/config/kibana.yml

6.单独启动 kibana 容器

sudo docker start novel-kibana

7.重设 elastic 账户密码，用来登录 kibana 控制台

sudo docker exec -it novel-elasticsearch bin/elasticsearch-reset-password --username elastic

8.使用上一步设置的账户和密码登录 kibana 控制台

注意：需要将 xxl-job 的数据库文件导入 MySQL 后，xxl-job-admin 才能正常访问。

顺便说下，novel-cloud 已经往 Spring Cloud 2022 的方向重构了，并且会适配 novel 项目的 Vue 前端，感兴趣的同学可以持续关注。
