Can't stop rails server
提问by epsilones
I am new to rails and I am using an ubuntu machine and the rubymine IDE. The problem is that I am unable to stop the rails server. I tried to stop the server by killing the rails process. But, when I run pgrep -l rails, no such process is found. So, I am only able to kill ruby processes, but, the server won't stop.
我是 Rails 的新手，我正在使用 ubuntu 机器和 rubymine IDE。问题是我无法停止 Rails 服务器。我试图通过杀死 rails 进程来停止服务器。但是，当我运行时pgrep -l rails，没有找到这样的进程。所以，我只能杀死 ruby 进程，但是，服务器不会停止。
I tried ./script/server stop(since I started it by running ./script/server start), but, that didn't work. Googling around and finding some stackoverflow posts, I tried to change the localhost port's listening port but without success. Could someone help?
我尝试过./script/server stop（因为我是通过运行启动它的./script/server start），但是，那没有用。谷歌搜索并找到一些stackoverflow帖子，我尝试更改本地主机端口的侦听端口但没有成功。有人可以帮忙吗？

You can use other ports like the following:
您可以使用其他端口，如下所示：
rails server -p 3001
Normally in your terminal you can try Ctrl + Cto shutdown the server.
通常在您的终端中，您可以尝试Ctrl + C关闭服务器。
The other way to kill the Ruby on Rails default server (which is WEBrick) is:
杀死 Ruby on Rails 默认服务器（即WEBrick）的另一种方法是：
kill -INT $(cat tmp/pids/server.pid)
In your terminal to find out the PID of the process:
在你的终端中找出进程的PID：
$ lsof -wni tcp:3000
Then, use the number in the PID column to kill the process:
然后，使用 PID 列中的数字来终止进程：
For example:
例如：
$ kill -9 PID
And some of the other answers i found is:
我发现的其他一些答案是：
To stop the rails server while it's running, press:
要在运行时停止 rails 服务器，请按：
CTRL-C
CTRL-Z
You will get control back to bash. Then type (without the $):
您将重新获得控制权bash。然后输入（不带$）：
$ fg
And this will go back into the process, and then quit out of Rails sproperly.
这将返回到进程中，然后退出Rails s正常。
It's a little annoying, but this sure beats killing the process manually. It's not too bad and it's the best I could figure out.
这有点烦人，但这肯定胜过手动终止进程。这还不错，这是我能想到的最好的。

pkill -9 rails杀死rails的所有进程
Updated answer
更新答案
ps aux|grep 'rails'|grep -v 'grep'|awk '{ print $2 }'|xargs kill -9
ps aux|grep 'rails'|grep -v 'grep'|awk '{ print $2 }'|xargs kill -9
This will kill any running rails process. Replace 'rails' with something else to kill any other processes.
这将杀死任何正在运行的 rails 进程。用其他东西替换“rails”以杀死任何其他进程。

Delete the server.pid from tmp/pids folder. In my case, the error was: A server is already running. Check /home/sbhatta/myapp/tmp/pids/server.pid.
从 tmp/pids 文件夹中删除 server.pid。就我而言，错误是：服务器已在运行。检查 /home/sbhatta/myapp/tmp/pids/server.pid。
So, I delete server.pid
所以，我删除了 server.pid
rm /home/sbhatta/myapp/tmp/pids/server.pidthen run rails s
rm /home/sbhatta/myapp/tmp/pids/server.pid然后运行 rails s

Use ctrl+cto shutdown your Webrick Server.
使用ctrl+c关机您的WEBrick服务器。
Unfortunately if its not works then forcefully close the terminal and restart it.
不幸的是，如果它不起作用，则强行关闭终端并重新启动它。
Another trick is that
另一个技巧是
1. open your system-monitor(a gui application) on ubuntu
2. Select processes tab
3. Then look for a process having name 'ruby'
4. End that process
