# deploy.py nginx 站点启用超时修复 — 实施计划 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. **Goal:** 修复 `python deploy.py` 中 nginx 站点启用命令 30s 超时问题,通过将链式 `ln -snf && rm -f` 拆为 5 步独立 SSH 调用 + 前置诊断清理。 **Architecture:** 在 `deploy.py` 中新增 `enable_nginx_site(remote_conf, domain)` 函数(5 步骤:诊断→清理→建链→清默认→验证),替换 `deploy_nginx` 第 250-253 行的链式命令。每步独立 `ssh_command(timeout=30)` 调用,失败立即停止;变量入口校验防御 shell 注入。 **Tech Stack:** Python 3.10+, subprocess (ssh/scp), bash test/case/ln 内置命令 --- ## 文件结构 **修改**:`G:\IdeaProjects\emotion-museun\deploy.py` - 新增函数 `enable_nginx_site`(在 `deploy_nginx` 之前,约 70 行) - 修改 `deploy_nginx`(第 250-256 行,替换链式命令为函数调用) **不修改**: - `ssh_command()` / `run_ssh_args()` / `scp_file()` 底层 - `conf/emotion-museum.conf` nginx 配置文件 - 其他 deploy.py 子脚本 --- ## Task 1: 添加 `enable_nginx_site` 函数骨架 + 变量安全校验 **Files:** - Modify: `G:\IdeaProjects\emotion-museun\deploy.py:230-266`(在 `deploy_nginx` 前插入新函数) - [ ] **Step 1: 在 `deploy_nginx` 之前插入新函数骨架** **Step 1a**:先在文件顶部 imports 区(第 23-28 行附近)追加 `import re`: 将 `deploy.py` 第 23-28 行: ```python import io import os import sys import time import subprocess from pathlib import Path ``` 改为: ```python import io import os import re import sys import time import subprocess from pathlib import Path ``` **Step 1b**:在 `deploy.py` 第 230 行(`# Nginx 配置` 注释之前)插入以下代码: ```python # ============================================================================ # Nginx 站点启用(防御性诊断 + 清理) # ============================================================================ # 变量安全校验正则 _SAFE_DOMAIN = re.compile(r'^[a-zA-Z0-9.-]+$') _SAFE_REMOTE_CONF = re.compile(r'^[a-zA-Z0-9./_-]+$') def _validate_nginx_inputs(remote_conf: str, domain: str) -> bool: """校验 domain 和 remote_conf 防止 shell 注入和路径遍历。 Returns: True 合法;False 非法(已 log_error) """ if not domain or not _SAFE_DOMAIN.match(domain): log_error(f"非法 domain 名称: {domain!r}") return False if domain.startswith('-') or domain.endswith('-') \ or domain.startswith('.') or domain.endswith('.') \ or '..' in domain: log_error(f"非法 domain 结构: {domain!r} (首尾连字符/点 或 连续点非法)") return False if not remote_conf or not _SAFE_REMOTE_CONF.match(remote_conf): log_error(f"非法 remote_conf 路径: {remote_conf!r}") return False if '//' in remote_conf or '..' in remote_conf: log_error(f"remote_conf 包含可疑路径片段: {remote_conf!r}") return False return True def enable_nginx_site(remote_conf: str, domain: str) -> bool: """幂等地启用 nginx 站点(sites-enabled symlink)。 流程: 1. 诊断目标路径当前状态(symlink/dir/file/missing) 2. 清理异常状态(目录/文件/断链);失败短路 3. 二次检查 + 创建 symlink 4. 移除 default 站点(失败仅 warning) 5. 验证 symlink + default 状态 Returns: True 成功;False 失败(stderr 已打印) """ if not _validate_nginx_inputs(remote_conf, domain): return False target = f"/etc/nginx/sites-enabled/{domain}.conf" log_info(f"启用 nginx 站点: {target} -> {remote_conf}") return True # 后续 Task 替换为完整 5 步实现 ``` - [ ] **Step 2: 验证 Python 语法正确** Run: `cd G:\IdeaProjects\emotion-museun && python -c "import ast;
