Server is already running in Rails

Question

When I am starting rails server using rails s command it is showing A server is already running. Check C:/Sites/folder/Pids/Server.pids

Whe

Answer 1

I just had this issue and tried setting it to a different port, but the only thing I needed to do was to delete my [app_directory]/tmp/pids/server.pid and everything was good to go.

Answer 2

On Windows Rails 5.2, delete this file

c:/Sites/<your_folder>/tmp/pids/server.pid

and run

rails s

again.

Answer 3

Run: fuser -k -n tcp 3000

This will kill the process running at the default port 3000.

Answer 4

Probably you suspended the server by: ^Z.

The four digital number that vim C:/Sites/folder/Pids/Server.pidsoutputs is the process id.

You should kill -9 processid, replacing the process id with the 4 numbers that vim (or other editor) outputed.

Answer 5

lsof -wni tcp:3000

Then you should see the ruby process and you can run

kill -9 processid

you should be good to run the process now

rails s thin

running multiple processes doesn't seem like a good idea and from what i've read many people agree. I've noticed many memory leaks with rails unfortunately so I couldn't imagine having two processes running. I know with one overtime my page refreshes increasingly become slower because of the data being stored on memory.

Answer 6

kill -9 $(lsof -i tcp:3000 -t)
