小编Tam*_*mpa的帖子

我试图在命令行中为ubuntu中的特定端口杀死一个进程.

如果我运行此命令,我会得到端口:

sudo lsof -t -i:9001

所以...现在我想跑:

sudo kill 'sudo lsof -t -i:9001'

我收到此错误消息:

ERROR: garbage process ID "lsof -t -i:9001".
Usage:
  kill pid ...              Send SIGTERM to every process listed.
  kill signal pid ...       Send a signal to every process listed.
  kill -s signal pid ...    Send a signal to every process listed.
  kill -l                   List all signal names.
  kill -L                   List all signal names in a nice table.
  kill -l signal            Convert between signal numbers and names.

我也试过 …

关于如何获取查询字符串的烧瓶文档并不明显.我是新人,看着文档,找不到!

所以

@app.route('/')
@app.route('/data')
def data():
    query_string=??????
    return render_template("data.html")

尝试按照从docker网站构建docker镜像的说明进行操作.

https://docs.docker.com/examples/running_redis_service/

这是我得到的错误将遵循文档上的说明并使用此Dockerfile

FROM        ubuntu:14.04
RUN         apt-get update && apt-get install -y redis-server
EXPOSE      6379
ENTRYPOINT  ["/usr/bin/redis-server"]


sudo docker build -t myrepo/redis
docker: "build" requires 1 argument. See 'docker build --help'.

如何解决？

我试图按照https://material.angular.io/components/component/dialog上的文档但我不明白为什么它有以下问题？

我在我的组件上添加了以下内容:

@Component({
  selector: 'dialog-result-example-dialog',
  templateUrl: './dialog-result-example-dialog.html',
})
export class DialogResultExampleDialog {
  constructor(public dialogRef: MdDialogRef<DialogResultExampleDialog>) {}
}

在我的模块中,我补充道

import { HomeComponent,DialogResultExampleDialog } from './home/home.component';

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent,
    DashboardComponent,
    HomeComponent,
    DialogResultExampleDialog
  ],

// ...

但我得到这个错误....

EXCEPTION: Error in ./HomeComponent class HomeComponent - inline template:53:0 caused by: No component factory found for DialogResultExampleDialog. Did you add it to @NgModule.entryComponents?
    ErrorHandler.handleError @ error_handler.js:50
    next @ application_ref.js:346
    schedulerFn @ async.js:91
    SafeSubscriber.__tryOrUnsub @ Subscriber.js:223
    SafeSubscriber.next @ Subscriber.js:172

使用NodeJS,我想将a格式化Date为以下字符串格式:

var ts_hms = new Date(UTC);
ts_hms.format("%Y-%m-%d %H:%M:%S");

我怎么做？

突然间,我得到了以下nginx错误

 * Restarting nginx
 * Stopping nginx nginx
   ...done.
 * Starting nginx nginx
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
   ...done.
   ...done.

如果我跑

lsof -i :80 …

我从Angular 2收到此错误

core.umd.js:5995 EXCEPTION:未捕获(在承诺中):错误:app/model_exposure_currencies/model_exposure_currencies.component.html:57:18中的错误:如果在表单标记中使用了ngModel,则name属性必须为set或表单控件必须在ngModelOptions中定义为"standalone".

      Example 1: <input [(ngModel)]="person.firstName" name="first">
      Example 2: <input [(ngModel)]="person.firstName" [ngModelOptions]="{standalone: true}">
<td *ngFor="let lag of ce.lags">
    <div class="form-group1">
        <input name="name" [(ngModel)]="lag.name" [ngModelOptions]="{standalone: true}"  class="form-control" pattern="[0-9]*(\.[0-9]+)?" required>
    </div>

</td>

这就是我使用表单标签的方式:

 <form #f="ngForm" (ngSubmit)="onSubmit()">

如何让mongo在ec2上使用已安装的驱动器？我真的不明白.我在ec2上附加了一个卷,以root身份格式化驱动器并以root身份启动,但作为root我无法访问？我在ubuntu 12.04上运行.没有其他mongo正在运行

我看到mongo在/ data ie/data/db中创建了一个'db'目录

cd /
ls -al
drwxr-xr-x  4 root root  4096 Mar  5 16:28 data

cd /data
ls -al
total 28
drwxr-xr-x  4 root root  4096 Mar  5 16:28 .
drwxr-xr-x 24 root root  4096 Mar  5 16:28 ..

我正在使用Flask,我从get请求返回一个XML文件.如何设置内容类型？

例如

@app.route('/ajax_ddl')
def ajax_ddl():
    xml = 'foo'
    header("Content-type: text/xml")
    return xml

我需要使用密码自动化ssh-keygen -t rsa,即输入提示符.我怎样才能从shell脚本中做到这一点？

谢谢
