A server is already running. Check …/tmp/pids/server.pid. Exiting - rails

Question

..$ rails s
=> Booting WEBrick
=> Rails 4.0.4 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=>         


        

Answer 1

server.pid only contains the process ID of the running server.

If you do:

more /your_project_path/tmp/pids/server.pid

you will get a number (say 6745) which you can use to stop the previous server with the command kill:

kill -9 6745

and then you can remove the file with the rm command

rm /your_project_path/tmp/pids/server.pid
