node.js - 我在Linux系统上实现了多个npm命令，所有这些命令都是使用nodejs启动一个网站，让它们在后台运行

Question

"start-client": "cross-env NODE_ENV=生产 Node ./server/index.js", "start-api": "cross-env NODE_ENV=生产 Node ./server/api/index.js", "start-pro": "同时\"npm run start-client\"\"npm run start-api\""

npm run start-pro在Liunx系统上运行成功，但我关闭 session 然后服务器结束。

当我运行 npm run start-pro & 命令时也可以，当我关闭 session 时出现 503 错误。

当我执行nohup npm run start-pro &这个命令的时候，在项目的根目录中出现了nohup.output的文件，里面记录了错误:

执行nohup npm run start-pro &命令时出现错误，错误在nohup.out文件中:

p2@0.1.0 start-pro /website/pgyer concurrently "npm run start-client" "npm run start-api"

events.js:160 throw er; // Unhandled 'error' event ^

Error: EBADF: bad file descriptor, read at Error (native) npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! p2@0.1.0 start-pro: concurrently "npm run start-client" "npm run start-api" npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the p2@0.1.0 start-pro script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in: npm ERR! /root/.npm/_logs/2018-07-18T00_30_14_968Z-debug.log

再试一次!现在先执行 nohup npm run start-api & 就成功了!然后执行 nobup npm run start-client & 命令也成功了!

So,i want to kown,how can i do one command to start two server:start-clientand start-api,and i close the session the server is ok?

您可以使用并发安装它

同时 npm install -g

或者如果您从 npm 脚本中使用它:

npm同时安装--save

 concurrently "command1 arg" "command2 arg"

欢迎访问https://www.npmjs.com/package/concurrently如果你想同时使用 else https://www.npmjs.com/package/npm-run-all如果你擅长使用npm-run-all

要在后台运行命令，请创建 app.js 并使用 npm 命令行库 https://www.npmjs.com/package/node-command-line

    function runMultipleCommandWithoutWait() {
  Promise.coroutine(function *() {
    var commands = ["node --version","npm --version"];
    for(var i=0; i < commands.length; i++) {
      cmd.run(commands[i]);
    }
    console.log('Executed your command :)');
  })();
}
