-## 如何部署
+## 前置工作
 
-> Step1 先克隆仓库
+先克隆仓库：
 
 ```shell
 git clone https://github.com/nagisa77/OpenIsle.git
 cd OpenIsle
 ```
 
-> Step2 后端部署
+- 后端开发环境
+    - JDK 17+
+- 前端开发环境
+    - Node.JS 20+
+
+## 启动后端服务
+
+启动后端服务有多种方式，选择一种即可。
+
+> [!IMPORTANT]
+> 仅想修改前端的朋友可不用部署后端服务。转到 [启动前端服务](#启动前端服务) 章节。
+
+### 本地 IDEA
 
 ```shell
-cd backend
+cd backend/
 ```
 
-以IDEA编辑器为例，IDEA打开backend文件夹。
+IDEA 打开 `backend/` 文件夹。
 
-- 设置VM Option，最好运行在其他端口，非8080，这里设置8081
+#### 配置环境变量
 
-```shell
+1. 生成环境变量文件
--Dserver.port=8081
+
+    ```shell
+    cp open-isle.env.example open-isle.env
+    ```
+
+    `open-isle.env.example` 是环境变量模板，`open-isle.env` 才是真正读取的内容
+
+2. 修改环境变量，留下需要的，比如你要开发 Google 登录业务，就需要谷歌相关的变量，数据库是一定要的
+
+    ![环境变量](assets/contributing/backend_img_7.png)
+
+3. 应用环境文件，选择刚刚的 `open-isle.env`
+
+可以在 `open-isle.env` 按需填写个性化的配置，该文件不会被 Git 追踪。比如你想把服务跑在 `8082`（默认为 `8080`），那么直接改 `open-isle.env` 即可：
+
+```ini
+SERVER_PORT=8082
 ```

+另一种方式是修改 `.properities` 文件（但不建议），位于 `src/main/application.properties`，该配置同样来源于 `open-isle.env`，但修改 `.properties` 文件会被 Git 追踪。
 
-- 设置jdk版本为java 17

+#### 配置 IDEA 参数
 
-- 本机配置MySQL服务（网上很多教程，忽略）
+- 设置 JDK 版本为 java 17
-- 设置环境变量.env 文件 或.properties 文件（二选一）
 
-1. 环境变量文件生成
+- 设置 VM Option，最好运行在其他端口，非 `8080`，这里设置 `8081`
+    若上面在环境变量中设置了端口，那这里就不需要再额外设置

+    ```shell

+    ```

+

+
+#### 配置 MySQL
+
+> [!TIP]
+> 如果不知道怎么配置数据库可以参考 [Docker 环境](#docker-环境) 章节
+
+1. 本机配置 MySQL 服务（网上很多教程，忽略）
+
+    + 可以用 Laragon，自带 MySQL 包括 Nodejs，版本建议 `6.x`，`7` 以后需要 Lisence
+    + [下载地址](https://github.com/leokhoa/laragon/releases)
+
+2. 填写环境变量
+
+    ![环境变量](assets/contributing/backend_img_6.png)
+
+    ```ini
+    MYSQL_URL=jdbc:mysql://<数据库地址>:<端口>/<数据库名>?useUnicode=yes&characterEncoding=UTF-8&useInformationSchema=true&useSSL=false&serverTimezone=UTC
+    MYSQL_USER=<数据库用户名>
+    MYSQL_PASSWORD=<数据库密码>
+    ```
+
+3. 执行 [`db/init/init_script.sql`](backend/src/main/resources/db/init/init_script.sql) 脚本，导入基本的数据
+    管理员：**admin/123456**
+    普通用户1：**user1/123456**
+    普通用户2：**user2/123456**
+    
+    ![初始化脚本](assets/contributing/resources_img.png)
+
+#### 配置 Redis
+
+填写环境变量 `.env` 中的 Redis 相关配置并启动 Redis
+
+```ini
+REDIS_HOST=<Redis 地址>
+REDIS_PORT=<Redis 端口>
 ```
 
-修改环境变量，留下需要的，比如你要开发Google登录业务，就需要谷歌相关的变量，数据库是一定要的

-
-2. 直接修改 .properities 文件
-
-位置src/main/application.properties, 数据库需要修改标红处，其他按需修改

-> Step3 前端部署
+### Docker 环境
 
-**⚠️ 环境要求：Node.js 版本最低 20.0.0（因为 Nuxt 框架要求）**
+#### 配置环境变量
-
-前端可以依赖本机部署的后端，也可以直接调用线上的后端接口
 
 ```shell
-cd ../frontend_nuxt/
+cd docker/
 ```
 
-copy环境.env文件
+主要配置两个 `.env` 文件
+
+- `backend/open-isle.env`：后端环境变量，配置同上，见 [配置环境变量](#配置环境变量)。
+- `docker/.env`：Docker Compose 环境变量，主要配置 MySQL 相关
+    ```shell
+    cp .env.example .env
+    ```
+
+> [!TIP]
+> 使用单独的 `.env` 文件是为了兼容线上环境或已启用 MySQL 服务的情况，如果只是想快速体验或者启动统一的环境，则推荐使用本方式。
+
+在指定 `docker/.env` 后，`backend/open-isle.env` 中以下配置会被覆盖，这样就确保使用了同一份配置。
+
+```ini
+MYSQL_URL=
+MYSQL_USER=
+MYSQL_PASSWORD=
+```
+
+#### 构建并启动镜像
 
 ```shell
-cp .env.staging.example .env
+docker compose up -d
 ```
 
-1. 依赖本机部署的后端：打开本文件夹，修改.env 修改为瞄准本机后端端口
+如果想了解启动过程发生了什么可以查看日志
 
-```yaml
+```shell
-; 本地部署后端
+docker compose logs
-NUXT_PUBLIC_API_BASE_URL=https://127.0.0.1:8081
-; 预发环境后端
-; NUXT_PUBLIC_API_BASE_URL=https://staging.open-isle.com
-; 生产环境后端
-; NUXT_PUBLIC_API_BASE_URL=https://www.open-isle.com
 ```
 
-2. 依赖预发环境后台环境
+## 启动前端服务
 
-**(⚠️强烈推荐只部署前端的朋友使用该环境)**
+> [!IMPORTANT]
+> **⚠️ 环境要求：Node.js 版本最低 20.0.0（因为 Nuxt 框架要求）**

-; 本地部署后端

-; NUXT_PUBLIC_API_BASE_URL=https://127.0.0.1:8081

+    ```
-```
+

+    cp .env.production.example .env
+    ```
+
+- 利用本地环境
+
+    ```shell
+    cp .env.dev.example .env
+    ```
+
+若依赖本机部署的后端，需要修改 `.env` 中的 `NUXT_PUBLIC_API_BASE_URL` 值与后端服务端口一致
