Notes on using PM2 to keep a Node.js application (Hexo) running persistently and auto-restarting after system reboot.
1. Install PM2
1
| npm install pm2@latest -g
|
2. Create a startup config

| module.exports = {
apps: [{
name: 'Hexo',
script: 'hexo',
args: 'server -p 4000',
watch: true,
log_file: 'server.log',
merge_logs: true,
out_file: 'NULL',
error_file: 'NULL'
}]
};

3. Start Hexo

| pm2 start start.config.js

Notes
- For local preview only, PM2 is unnecessary —
hexo server is enough.
- For a stable long-running Hexo server on a VPS, PM2 is more reliable than keeping a terminal session open.
- For GitHub Pages deployments, PM2 is not needed at all — you only run
hexo generate and deploy static files.
记录如何用 PM2 让 Node.js 应用（Hexo）持久运行，并在系统重启后自动恢复。

3. 启动 Hexo
1
| pm2 start start.config.js
|
4. 配置开机自启
5. 常用管理命令

说明
- 如果只是本地临时预览，不需要 PM2，直接
hexo server 即可。
- 如果在 VPS 上长期运行 Hexo 服务，PM2 比手工保持终端会话更可靠。
- GitHub Pages 场景下完全不需要 PM2，只需生成静态文件并部署。
