+# 本地安装 Nginx 和 Java 手册
+
+## 适用范围
+
+本手册适用于需要在本地 Linux 环境手动安装贷款定价系统运行环境的场景，安装结果与当前生产脚本约定保持一致：
+
+- Java 安装到 `/home/webapp/env/java`
+- Nginx 安装到 `/home/webapp/env/nginx`
+- 项目部署目录使用 `/home/webapp/loan-pricing`
+- 后端服务端口固定为 `63310`
+- 前端 Nginx 端口固定为 `63311`
+
+## 前置条件
+
+安装前请先确认：
+
+- 当前用户具备 `root` 权限
+- 本机已配置可用的 `yum` 源
+- `/home/webapp` 目录已存在
+- `/home/webapp` 下已准备安装包：
+  - `openjdk-21.0.2_linux-aarch64_bin.tar.gz`
+  - `nginx-1.20.2.tar.gz`
+
+如果安装包文件名不同，只要仍是 Java 的 `tar.gz` 包和 Nginx 的源码 `tar.gz` 包，也可以使用同样步骤。
+
+## 目录规划
+
+安装完成后目录结构如下：
+
+```text
+/home/webapp
+├── env
+│   ├── java
+│   └── nginx
+└── loan-pricing
+    ├── backend
+    ├── frontend
+    ├── backup
+    ├── logs
+    ├── run
+    └── tmp
+```
+
+## 第一步：安装系统依赖
+
+执行以下命令安装编译 Nginx 和运行部署脚本所需依赖：
+
+```sh
+yum install -y \
+  gcc \
+  make \
+  pcre \
+  pcre-devel \
+  zlib \
+  zlib-devel \
+  openssl \
+  openssl-devel \
+  tar \
+  gzip \
+  unzip \
+  which \
+  findutils \
+  procps-ng \
+  iproute
+```
+
+## 第二步：创建目录
+
+执行以下命令初始化目录：
+
+```sh
+mkdir -p \
+  /home/webapp/env \
+  /home/webapp/loan-pricing/backend \
+  /home/webapp/loan-pricing/frontend \
+  /home/webapp/loan-pricing/backup \
+  /home/webapp/loan-pricing/logs \
+  /home/webapp/loan-pricing/run \
+  /home/webapp/loan-pricing/tmp
+```
+
+## 第三步：安装 Java
+
+解压 Java 安装包到目标目录：
+
+```sh
+rm -rf /home/webapp/env/java
+mkdir -p /home/webapp/env/java
+tar -xzf /home/webapp/openjdk-21.0.2_linux-aarch64_bin.tar.gz -C /home/webapp/env/java --strip-components=1
+```
+
+验证安装结果：
+
+```sh
+/home/webapp/env/java/bin/java -version
+```
+
+如果能正常输出 Java 版本，说明安装成功。
+
+## 第四步：安装 Nginx
+
+Nginx 安装包为源码包，需要先解压、编译、安装：
+
+```sh
+rm -rf /home/webapp/env/nginx
+mkdir -p /home/webapp/env/nginx
+mkdir -p /home/webapp/env/nginx-build
+tar -xzf /home/webapp/nginx-1.20.2.tar.gz -C /home/webapp/env/nginx-build
+cd /home/webapp/env/nginx-build/nginx-1.20.2
+./configure --prefix=/home/webapp/env/nginx --with-http_ssl_module
+make -j"$(getconf _NPROCESSORS_ONLN 2>/dev/null || echo 1)"
+make install
+```
+
+安装完成后可执行文件位置为：
+
+```text
+/home/webapp/env/nginx/sbin/nginx
+```
+
+## 第五步：写入 Nginx 配置
+
+仓库已提供可直接参考的配置文件：
+
+```text
+deploy/nginx.conf
+```
+
+将该文件内容写入 `/home/webapp/env/nginx/conf/nginx.conf` 即可。
+
+## 第六步：校验 Nginx 配置
+
+执行：
+
+```sh
+/home/webapp/env/nginx/sbin/nginx -t -c /home/webapp/env/nginx/conf/nginx.conf
+```
+
+如果输出 `syntax is ok` 和 `test is successful`，说明配置可用。
+
+## 第七步：启动 Nginx
+
+执行：
+
+```sh
+/home/webapp/env/nginx/sbin/nginx -c /home/webapp/env/nginx/conf/nginx.conf
+```
+
+如果后续修改了配置，可执行：
+
+```sh
+/home/webapp/env/nginx/sbin/nginx -c /home/webapp/env/nginx/conf/nginx.conf -s reload
+```
+
+## 第八步：验证端口
+
+执行：
+
+```sh
+ss -lnt | grep 63311
+```
+
+如果能看到 `63311` 监听记录，说明前端 Nginx 已启动成功。
+
+## 建议执行方式
+
+如果本机已经放置了以下脚本，也可以直接使用脚本完成安装：
+
+```sh
+cd /home/webapp
+./install_env.sh
+```
+
+如果只需要管理后端 Java 进程，可执行：
+
+```sh
+cd /home/webapp
+./restart_java.sh start
+./restart_java.sh stop
+./restart_java.sh restart
+./restart_java.sh status
+```
+
+## 常见检查项
+
+- `yum` 不可用：先确认系统已配置可用的 `yum` 源
+- Java 未安装成功：检查 `/home/webapp/openjdk-*.tar.gz` 是否存在且未损坏
+- Nginx 编译失败：检查 `gcc`、`make`、`pcre-devel`、`zlib-devel`、`openssl-devel` 是否已安装
+- Nginx 启动失败：先执行 `nginx -t` 查看配置是否正确
+- 前端无法访问后端：检查本机 `63310` 端口是否已有 Java 服务监听

+# 生产环境安装与部署脚本实施记录

+## 修改内容
+- 新增生产环境安装脚本 `bin/prod/install_env.sh`
+- 新增生产环境部署脚本 `bin/prod/deploy_release.sh`
+- 新增生产环境 Java 管理脚本 `bin/prod/restart_java.sh`
+- 两份脚本需要同步放置到生产容器 `/home/webapp` 目录，便于在目标环境直接执行
+- 部署脚本改为复用独立的 Java 管理脚本完成后端启停
+- 安装脚本固定将 Java 安装到 `/home/webapp/env/java`，将 Nginx 安装到 `/home/webapp/env/nginx`
+- 安装脚本会创建 `/home/webapp/loan-pricing` 下的 `backend`、`frontend`、`backup`、`logs`、`run`、`tmp` 目录，并写入 Nginx 配置
+- 部署脚本约定发布包内必须包含 1 个后端 `jar` 和 1 个 `dist.zip`
+- 部署脚本在发布前会备份旧版后端 jar 与旧版前端 `dist` 目录，再完成替换、启动后端和重载 Nginx
+- Nginx 前端监听端口固定为 `63311`，后端应用启动端口固定为 `63310`
+
+## 环境勘察结论
+- 已连接生产服务器 `116.62.17.81:9444` 并进入 `loan-pricing` 容器核对目录结构
+- 容器内实际工作目录为 `/home/webapp`
+- 已确认当前容器中存在安装包：
+  - `/home/webapp/openjdk-21.0.2_linux-aarch64_bin.tar.gz`
+  - `/home/webapp/nginx-1.20.2.tar.gz`
+- 已确认当前容器尚不存在 `/home/webapp/loan-pricing`
+- 已确认当前容器当前没有运行中的 Java 或 Nginx 进程
+- 当前被勘察容器基础镜像为 Ubuntu；但脚本已按需求改为基于 `yum` 安装系统依赖，适配正式生产环境约束
+- 已确认当前容器无法直接安装原生 `yum` 包，但系统仓库提供 `dnf` 包，可通过 `dnf` 提供 `yum` 兼容执行入口
+
+## 验证结果
+- 已执行 `sh -n bin/prod/install_env.sh`
+- 已执行 `sh -n bin/prod/deploy_release.sh`
+- 已将两份脚本同步到生产 `loan-pricing` 容器：
+  - `/home/webapp/install_env.sh`
+  - `/home/webapp/deploy_release.sh`
+- 已将 Java 管理脚本同步到生产 `loan-pricing` 容器：
+  - `/home/webapp/restart_java.sh`
+- 已在容器内执行 `ls -l /home/webapp/install_env.sh /home/webapp/deploy_release.sh /home/webapp/restart_java.sh`，确认三份脚本均已落盘且具备可执行权限
+- 已在容器内执行：
+  - `sh -n /home/webapp/install_env.sh`
+  - `sh -n /home/webapp/deploy_release.sh`
+  - `sh -n /home/webapp/restart_java.sh`
+  三份线上脚本语法校验均已通过
+- 已确认 Ubuntu 24.04 仓库中 `yum` 包候选为空，`dnf` 包候选为 `4.14.0-4.1ubuntu1`
+- 已在生产 `loan-pricing` 容器执行 `apt-get install -y dnf dnf-plugins-core`
+- 已在生产 `loan-pricing` 容器创建 `yum` 兼容入口：
+  - `/usr/local/bin/yum -> /usr/bin/dnf`
+- 已执行 `yum --version`，返回 `4.14.0`
+- 已人工核对脚本中的关键路径、端口与部署约束：
+  - Java 安装目录 `/home/webapp/env/java`
+  - Nginx 安装目录 `/home/webapp/env/nginx`
+  - 项目部署目录 `/home/webapp/loan-pricing`
+  - 前端端口 `63311`
+  - 后端端口 `63310`
+- 由于当前已连接勘察容器为 Ubuntu 24.04，不具备本次脚本要求的 `yum` 安装前提，因此未在该容器直接执行安装流程，仅完成语法校验与逻辑核对

+## 原因说明
+- 当前线上 Nginx 实际以 `nobody` worker 进程运行
+- 但配置文件未显式声明 worker 用户，后续重写配置时容易与实际运行态不一致
+- 显式声明 `user nobody;` 可以让配置意图与当前运行方式保持一致
+
+## 验证结果
+- 已完成仓库配置文件与安装脚本模板修改
+- 已同步修改线上实际配置 `/volume1/webapp/env/nginx/conf/nginx.conf`
+- 已执行 `nginx -t -c /home/webapp/env/nginx/conf/nginx.conf`，语法校验通过
+- 已执行 Nginx reload，容器内进程显示 `nobody` 作为 worker 用户运行
+- 已执行 `curl -I http://116.62.17.81:63311/`，返回 `HTTP/1.1 200 OK`
+- 已执行 `curl http://116.62.17.81:63311/prod-api/login/test`，返回状态码 `200`
