javascript - SSH 进入远程机器并在 Node.js 中执行命令

Question

我正在寻找一种通过 SSH 连接到虚拟机然后使用 Node.js 在虚拟机中执行某些脚本的方法

到目前为止，我已经创建了自动登录到虚拟机的 shell 脚本，但我无法弄清楚如何继续。

登录远程服务器的shell脚本

spawn ssh root@localhost
expect "password"
send "123456"
send "\r"
interact

这是我的 server.js

var http = require('http');
var execProcess = require("./exec_process.js");
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  execProcess.result("sh sshpass.sh", function(err, response){
        if(!err){
            res.end(response);
        }else {
            res.end("Error: ", err);
        }
    });
}).listen(3000);
console.log('Server listening on port 3000');

exec_process.js

var exec = require('child_process').exec;

var result = function(command, cb){
    var child = exec(command, function(err, stdout, stderr){
        if(err != null){
            return cb(new Error(err), null);
        }else if(typeof(stderr) != "string"){
            return cb(new Error(stderr), null);
        }else{
            return cb(null, stdout);
        }
    });
}

exports.result = result;

感谢任何帮助

你为什么不使用simple-ssh ？

我做了一个简单的例子，说明如何加载一个包含命令列表的文件并在链中执行它们。

exampleList :(命令必须换行)

echo "Testing the first command"
ls

sshtool.js :(它可能有问题，例如:如果任何命令包含 \n)

const _ = require("underscore");
//:SSH:
const SSH = require('simple-ssh');
const ssh = new SSH({
    host: 'localhost',
    user: 'username',
    pass: 'sshpassword'
});
//example usage : sshtool.js /path/to/command.list
function InitTool(){
 console.log("[i] SSH Command Tool");
 if(process.argv[2]){AutomaticMode();}
 else{console.log("[missing argument : path to file containing the list of commands]");}
}
//:MODE:Auto
function AutomaticMode(){
 const CMDFileName = process.argv[2];
 console.log("  ~ Automatic Command Input Mode");
 //Load the list of commands to be executed in order
 const fs = require('fs');
 fs.readFile(process.argv[2], "utf8", (err, data) => {
  if(err){console.log("[!] Error Loading Command List File :\n",err);}else{
    var CMDList = data.split("\n"); // split the document into lines
    CMDList.length = CMDList.length - 1; //fix the last empty line
    _.each(CMDList, function(this_command, i){
      ssh.exec(this_command, {
       out: function(stdout) {
        console.log("[+] executing command",i,"/",CMDList.length,"\n  $["+this_command+"]","\n"+stdout);
       }
      });
    });
    console.log("[i]",CMDList.length,"commands will be performed.\n");
    ssh.start();
  }
 });
}
//:Error Handling:
ssh.on('error', function(err) {
 console.log('[!] Error :',err);
 ssh.end();
});

InitTool();

它使用 underscore用于遍历命令列表。
