nginx: [alert] could not open error log file: CreateFile() “logs/error.log“ failed (3: The system ca

原因：没有进入nginx安装文件夹下面执行操作nginx的命令  

自己写了个用node启动nginx的脚本  

// 启动关闭系统中安装的nginx服务
import chalk from 'chalk'
import { exec } from 'child_process'
// import util from 'util'

// const execPromise = util.promisify(exec)

const nginxPath = process.env.Path.split(';').find((item) => {
  return item.includes('nginx')
})
const _pIndex = process.argv.findIndex((item) => item === '-p')
const val = process.argv[_pIndex + 1] || ''
if (nginxPath) {
  console.log(chalk.blue('nginx地址为:'), nginxPath)
} else {
  console.log(chalk.red('您的操作系统未配置nginx的环境变量'))
}
process.chdir(nginxPath)

function handleCallback(error, stdout, stderr) {
  if (error) {
    console.error(chalk.red(`执行出错: ${error.message}`))
    return
  }
  if (stderr) {
    console.error(chalk.red(`标准错误输出: ${stderr}`))
    return
  }
  console.log(chalk.green(`标准输出: ${stdout}`))
  // process.exit(0)
}

// async function runCommand() {
//   try {
//     const { stdout, stderr } = await execPromise(
//       val === 'start' ? 'start nginx' : 'nginx -s stop',
//       { cwd: nginxPath },
//     )
//     console.log(`标准输出: ${stdout}`)
//     if (stderr) {
//       console.error(`标准错误输出: ${stderr}`)
//     }
//   } catch (err) {
//     console.log('执行出错', err)
//   }
// }

if (val === 'start') {
  const pr = exec(
    'start nginx',
    { cwd: nginxPath, timeout: 1000 },
    handleCallback,
  )
  pr.stdout.on('data', (data) => {
    console.log('data', data)
  })
} else if (val === 'stop') {
  exec('nginx -s stop', { cwd: nginxPath, timeout: 1000 }, handleCallback)
}
// 改变工作目录
// console.log('cwd', process.cwd())

// runCommand()
