正在做Hart的Rails教程,但是服务器不会为我关闭,而是在更新后启动它 [英] Doing Hart's Rails Tutorial, but server won't shut down for me fire it up after updates
问题描述
我对各种文件进行了一些更改,需要关闭然后重新启动服务器才能查看它们。我正在使用Cloud9导航环境。但是我一直收到相同的错误-服务器已在运行。请参阅以下内容:
I have made some changes to various files, and need to shut down and then restart the server to see them. I am using the Cloud9 railstutorial environment. But I keep getting the same error - "A server is already running". Please see below:
darrenbrett:~/workspace/sample_app (filling-in-layout) $ rails server -b $IP -p $PORT
=> Booting WEBrick
=> Rails 4.2.2 application starting in development on http://0.0.0.0:8080
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
A server is already running. Check /home/ubuntu/workspace/sample_app/tmp/pids/server.pid.
Exiting
darrenbrett:~/workspace/sample_app (filling-in-layout) $
推荐答案
首先找出进程ID( PID
):
Find out the process id (PID
) first:
$ lsof -wni tcp:8080
这会给你像这样的东西:
This will give you something like this:
$ lsof -wni tcp:8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ruby 59656 rislam 14u IPv6 0xa86b8563672ef037 0t0 TCP [::1]:http-alt (LISTEN)
然后,使用 PID = 59656终止进程(例如,对于您来说情况会有所不同)
:
$ kill -9 59656
此应该可以解决您的问题。
This should solve your problem.
您还可以使用以下命令杀死所有正在运行的应用程序,这些应用程序中有 rails
名称:
You can also use the following command to kill all running apps that has rails
in the name:
killall -9 rails
有时候,这非常当第一个命令不起作用时有效。
Sometimes, this is very effective when the first command does not do the trick.
