A server is already running. Check …/tmp/pids/server.pid. Exiting - rails
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
You can delete the server.pid file.
rm /your_project_path/tmp/pids/server.pid
Else:
try in OSX:
sudo lsof -iTCP -sTCP:LISTEN -P | grep :3000
or in linux:
ps -aef | grep rails
or
lsof -wni tcp:3000
kill the process using
kill -9 PID (eg,2786)
Short and Crisp single line command, that will take care of it.
kill -9 $(lsof -i tcp:3000 -t)
If you are using docker-compose, and in docker-compose.yml have:
volumes:
- .:/myapp
That means you local workspace is mapped to the container's /myapp folder.
Anything in /myapp will not be deleted for the volumes define.
You can delete ./tmp/pids/server.pid in you local machine. Then the container's /myapp will not have this file.
