Fix error bind() fail on sphinx

We should try 2 command before this below guide :

the 'init: ... main process ended, respawning' suggests there is something in the init script that sets a watchdog to make sure sphinx doesnt die.

Perhaps you need to shutdown sphinx via the init script itself

/etc/init.d/sphinxsearch stop

or

By default, it seems like the debian package will start Sphinx with an additional keepalive process. I was able to stop it successfully with this;

sudo service sphinxsearch stop

If 2 way above is not success, you should try.
using config file '/sphinx/conf/sphinx.conf'...
listening on all interfaces, port=9312
bind() failed on 0.0.0.0, retrying...
bind() failed on 0.0.0.0, retrying...
bind() failed on 0.0.0.0, retrying...
bind() failed on 0.0.0.0, retrying...
bind() failed on 0.0.0.0, retrying...
bind() failed on 0.0.0.0, retrying...

If happend error like this, the best way , you should change port in config file
Change 9312 to some other port.


listen = 9312
listen = 9306:mysql41

To 

listen = 9314
listen = 9308:mysql41
