关闭我的ssh会话后，如何保持Django服务器的运行？ [英] How do I keep my Django server running even after I close my ssh session?

问题描述

我想出如何通过 sudo python /home/david/myproject/manage.py runserver 68.164.125.221:80 运行我的Django应用程序。但是，在我退出终端后，服务器停止运行。

我在后台运行这个进程，但服务器在执行 sudo python /home/david/myproject/manage.py runserver 68.164.125.221:80& 。

我如何保持我的Django应用程序即使在终端终止我的ssh会话之后仍在运行？

PS - 如果这个问题引起了你的关注，对不起，当前端的JavaScript程序员必须变成服务器管理员时，这种愚蠢的事情就是分崩离析的。

解决方案

认识屏幕。

通过ssh连接，开始画面这个在ssh提供的虚拟控制台模拟器上打开。启动您的服务器。

然后按Ctrl-a，然后按d。这将分离屏幕会话，使其在后台运行。

要[R]附加到它，请使用屏幕-r。

如果屏幕未安装，您无法安装，您还可以在后台启动应用程序，添加&按照你的想法，但你不应该关闭终端窗口;只需断开连接，使用bash命令退出或Ctrl-d。

屏幕的优点是您仍然可以从服务器读取输出，以防万一有错误或任何东西。

屏幕是一个非常强大的工具，还有更多的命令。您可以使用Ctrl-a添加新的虚拟窗口，然后添加c（用于创建）;切换到带有Ctrl-a，然后是n（下一个）或p（上一个）的窗口，...

但是您需要安装才能使用它。因为你似乎有root权限，这不应该是一个问题。

编辑： tmux 是同一用例的另一个很好的解决方案。

I figured out how to run my Django application via sudo python /home/david/myproject/manage.py runserver 68.164.125.221:80. However, after I quit terminal, the server stops running.

I tried to run this process in the background, but the server just shuts down quickly after I execute sudo python /home/david/myproject/manage.py runserver 68.164.125.221:80 &.

How do I keep my Django application running even after I quit my ssh session in terminal?

PS - Sorry if this question strikes you as elementary. Such sillyness ensues when a front-end javascript programmer must turn into a server administrator in break-neck speed.

解决方案

Meet screen.

Connect through ssh, start screen. This open a virtual console emulator on top of the one provided by ssh. Start your server there.

Then press Ctrl-a, then d. This detach the screen session, keeping it running in the background.

To [R]e-attach to it, use screen -r.

If screen is not installed and you can't install it, you can also start an application in the background by adding a & to the command, as you tried. But you should not close the terminal window then ; just disconnect, with the bash command exit, or Ctrl-d.

The advantage of screen is that you can still read the output from the server, in case there is an error or anything.

Screen is a really powerful tool, with many more commands. You can add a new virtual window with Ctrl-a, then c (for Create) ; switch through windows with Ctrl-a, then n (next) or p (previous), ...

But you need it to be installed to use it. Since you seem to have root access, this shouldn't be a problem.

EDIT: tmux is another great solution for the same use-case.
