Python Socket.Error: [Errno 98] Address Already In Use
when I set up application.py, it shows oserror: [errno 98] address already in use
Traceback (most recent call last): File "application.py", line 121, in main() File "application.py", line 117, in main http_server.listen(options.port) File "/usr/local/lib/python2.7/site-packages/tornado-3.1-py2.7.egg/tornado/tcpserver.py", line 117, in listen sockets = bind_sockets(port, address=address) File "/usr/local/lib/python2.7/site-packages/tornado-3.1-py2.7.egg/tornado/netutil.py", line 90, in bind_sockets sock.bind(sockaddr) File "/usr/local/ lib/python2.7/socket.py", line 224, in meth return getattr(self._sock,name)(*args) socket.error: [Errno 98] Address already in use Regarding the oserror: [errno 98] address already in use This happens because you trying to run service at the same port and there is an already running application. it can happen because your service is not stopped in the process stack. you just have to kill those processes. There is no need to install anything here is the one line command to kill all running python processes.
for Linux based OS:
Bash:
kill -9 $(ps -A | grep python | awk '{print $1}')
Fish:
kill -9 (ps -A | grep python | awk '{print $1}')
