Linux如何配置Node.js内存限制

<code>export NODE_OPTIONS="--max-old-space-size=4096"
node your-app.js</code>

<code>npm install pm2 -g</code>

<code>module.exports = {
  apps: [{
    name: 'your-app',
    script: 'your-app.js',
    instances: 'max', // 可指定具体数量
    exec_mode: 'cluster', // 或者 'fork'
    max_memory_restart: '4G' // 设置内存上限
  }]
};</code>

<code>pm2 start ecosystem.config.js</code>

<code>FROM node:14
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["node", "your-app.js"]</code>

<code>docker run -m 4g --name your-app-container your-app-image</code>

<code>version: '3.8'
services:
  your-app:
    image: your-app-image
    deploy:
      resources:
        reservations:
          memory: 4g
        limits:
          memory: 4g</code>

<code>docker-compose up</code>

<code>const v8 = require('v8');

// 设定内存上限为4GB
v8.setFlagsFromString('--max-old-space-size=4096');

// 启动应用
require('./your-app.js');</code>
