在Linux下如何在Node.js中并行运行两个程序

const { spawn } = require('child_process');

// 启动第一个程序
const program1 = spawn('node', ['path/to/program1.js']);

// 启动第二个程序
const program2 = spawn('node', ['path/to/program2.js']);

// 监听第一个程序的输出
program1.stdout.on('data', (data) => {
  console.log(`Program 1 output: ${data}`);
});

// 监听第二个程序的输出
program2.stdout.on('data', (data) => {
  console.log(`Program 2 output: ${data}`);
});

// 监听子进程关闭事件
program1.on('close', (code) => {
  console.log(`Program 1 exited with code ${code}`);
});

program2.on('close', (code) => {
  console.log(`Program 2 exited with code ${code}`);
});

const cluster = require('cluster');
const os = require('os');

if (cluster.isMaster) {
  // 获取CPU核心数
  const numCPUs = os.cpus().length;

  // 创建工作进程
  for (let i = 0; i < numCPUs; i++) {
    cluster.fork();
  }
} else {
  // 启动第一个程序
  const program1 = spawn('node', ['path/to/program1.js']);

  // 启动第二个程序
  const program2 = spawn('node', ['path/to/program2.js']);

  // 监听第一个程序的输出
  program1.stdout.on('data', (data) => {
    console.log(`Program 1 output: ${data}`);
  });

  // 监听第二个程序的输出
  program2.stdout.on('data', (data) => {
    console.log(`Program 2 output: ${data}`);
  });

  // 监听子进程关闭事件
  program1.on('close', (code) => {
    console.log(`Program 1 exited with code ${code}`);
  });

  program2.on('close', (code) => {
    console.log(`Program 2 exited with code ${code}`);
  });
}
