Okay, you're probably wondering why your searchd daemon won't bind to your desired port and this looks a like a familiar screen dump to you:

WARNING: compat_sphinxql_magics=1 is deprecated; please update your application and config
listening on 127.0.0.1:9306
bind() failed on 127.0.0.1, retrying...
bind() failed on 127.0.0.1, retrying...
bind() failed on 127.0.0.1, retrying...
bind() failed on 127.0.0.1, retrying...
bind() failed on 127.0.0.1, retrying...
FATAL: bind() failed on 127.0.0.1: Address already in use

Here's what to do:

  1. Check for running searchd instances. You might have another instance running on your desired port.

    ps aux | grep "searchd"

  2. To check for processes running and who runs them, you can execute:

    ps -ef | fgrep searchd

  3. If you find some running instances, kill those PID numbers. Or, you can simply kill all running searchd instances (be careful if you're not the only app/user running searchd).

    killall searchd

  4. If you find that your process is being run by root, then it will keep respawning if it is set as a service. You can edit vim /etc/default/sphinxsearch and modify it from START=yes to START=no

  5. ???

  6. Try to run your searchd again, and hopefully you'll get a successful start now.

Happy coding!
