+#### **⚠️注意：仅想修改前端的朋友可不用部署后端服务**
+
+## 如何部署
+
+> Step1 先克隆仓库
+
+```shell
+git clone https://github.com/nagisa77/OpenIsle.git
+cd OpenIsle
+```
+
+> Step2 后端部署
+
+```shell
+cd backend
+```
+
+以IDEA编辑器为例，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
+
+```shell
+-Dserver.port=8081
+```
+

+
+- 设置jdk版本为java 17
+
+![CleanShot 2025-08-04 at 11 .38.03@2x.png](https://openisle-1307107697.cos.accelerate.myqcloud.com/dynamic_assert/392eeec753ae436ca12a78f750dfea2d.png)
+
+- 本机配置MySQL服务（网上很多教程，忽略）
+- 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
+
+```shell
+cp open-isle.env.example open-isle.env
+```
+
+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
+
+![CleanShot 2025-08-04 at 11 .41.36@2x.png](https://openisle-1307107697.cos.accelerate.myqcloud.com/dynamic_assert/896c8363b6e64ea19d18c12ec4dae2b4.png)
+
+应用环境文件， 选择刚刚的`open-isle.env`
+
+![CleanShot 2025-08-04 at 11 .44.41.png](https://openisle-1307107697.cos.accelerate.myqcloud.com/dynamic_assert/f588e37838014a6684c141605639b9fa.png)
+
+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
+
+![CleanShot 2025-08-04 at 11 .47.11@2x.png](https://openisle-1307107697.cos.accelerate.myqcloud.com/dynamic_assert/28c3104448a245419e0b06aee861abb4.png)
+
+处理完环境问题直接跑起来就能通了
+
+![CleanShot 2025-08-04 at 11 .49.01@2x.png](https://openisle-1307107697.cos.accelerate.myqcloud.com/dynamic_assert/2c945eae44b1477db09e80fc96b5e02d.png)
+
+> Step3 前端部署
+
+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/
+```
+
+copy环境.env文件
+
+```shell
+cp .env.staging.example .env
+```
+
+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
+
+```yaml
+; 本地部署后端
+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
+
+**(⚠️强烈推荐只部署前端的朋友使用该环境)**
+
+```yaml
+; 本地部署后端
+; 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
+```
+
+4. 依赖线上后台环境
+
+```yaml
+; 本地部署后端
+; 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
+```
+
+```shell
+# 安装依赖
+npm install --verbose
+
+# 运行前端服务
+npm run dev
+```
+
+如此一来，浏览器访问 http://127.0.0.1:3000 即可访问前端页面

 ## 💡 简介
 
 OpenIsle 是一个使用 Spring Boot 和 Vue 3 构建的全栈开源社区平台，提供用户注册、登录、贴文发布、评论交互等完整功能，可用于项目社区或直接打造自主社区站点。
 
-## 🚧 开发
+## 🚧 开发 & 部署
 
-### 后端
-
-1. 确保安装 JDK 17 及 Maven
-2. 信息配置修改 `src/main/resources/application.properties`，或通过环境变量设置数据库等参数
-3. 执行 `mvn clean package` 生成包，之后使用 `java -jar target/openisle-0.0.1-SNAPSHOT.jar`启动，或在开发时直接使用 `mvn spring-boot:run`
-
-### 前端
-
-1. 进入前端目录
-    ```bash
-    cd frontend_nuxt
-    ```
-2. 安装依赖
-    ```bash
-    npm install
-    ```
-3. 启动开发服务
-    ```bash
-    npm run dev
-    ```
-
-    生产版本使用如下命令编译：
-
-    ```bash
-    npm run build
-    ```
-
-    会在 `.output` 目录生成文件，配合线上网站方式部署
