# 生产部署指南
|
||||
|
||||
## 目录结构
|
||||
|
||||
```
|
||||
/www/chat-app/
|
||||
├── public/ # 前端 dist + PHP 入口
|
||||
│ ├── index.html # 前端入口
|
||||
│ ├── assets/ # 前端 JS/CSS
|
||||
│ └── index.php # PHP 后端入口
|
||||
├── src/ # PHP 业务代码
|
||||
├── vendor/ # composer 依赖
|
||||
├── chat.db # SQLite 数据库
|
||||
└── composer.json
|
||||
```
|
||||
|
||||
## 部署步骤
|
||||
|
||||
### 1. 安装 PHP 依赖
|
||||
|
||||
```bash
|
||||
cd /www/chat-app
|
||||
composer install --no-dev --optimize-autoloader
|
||||
```
|
||||
|
||||
### 2. 前端构建并放入 public
|
||||
|
||||
本地执行:
|
||||
```bash
|
||||
npm run build
|
||||
cp -r dist/* server/public/
|
||||
```
|
||||
|
||||
### 3. Nginx 配置
|
||||
|
||||
```nginx
|
||||
server {
|
||||
listen 80;
|
||||
server_name your-domain.com;
|
||||
root /www/chat-app/public;
|
||||
index index.html index.php;
|
||||
|
||||
# 前端静态资源(JS/CSS/图片等)
|
||||
location /assets/ {
|
||||
try_files $uri =404;
|
||||
expires 1y;
|
||||
add_header Cache-Control "public, immutable";
|
||||
}
|
||||
|
||||
# API 请求 → PHP
|
||||
location /api/ {
|
||||
try_files $uri /index.php$is_args$args;
|
||||
}
|
||||
|
||||
# 前端路由(SPA)→ index.html
|
||||
location / {
|
||||
try_files $uri $uri/ /index.html;
|
||||
}
|
||||
|
||||
location ~ \.php$ {
|
||||
fastcgi_pass 127.0.0.1:9000; # 或 unix:/run/php/php8.3-fpm.sock
|
||||
fastcgi_index index.php;
|
||||
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
|
||||
include fastcgi_params;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. PHP-FPM 配置要点
|
||||
|
||||
确保 `php.ini` 中:
|
||||
```ini
|
||||
; SQLite 需要
|
||||
extension=pdo_sqlite
|
||||
|
||||
; SSE 流式输出需要
|
||||
output_buffering = Off
|
||||
zlib.output_compression = Off
|
||||
```
|
||||
|
||||
### 5. 数据库权限
|
||||
|
||||
```bash
|
||||
chmod 666 /www/chat-app/chat.db
|
||||
```
|
||||
|
||||
## 简化版:PHP 内置服务器(仅测试)
|
||||
|
||||
```bash
|
||||
cd /www/chat-app/public
|
||||
php -S 0.0.0.0:8000
|
||||
```
|
||||
|
||||
> 注意:PHP 内置服务器性能差,不适合生产。
