To upgrade Sphinx, do the same when installing :

(but remember to remove spl files)
BACKUP :
Make a backup of /usr/local/bin/searchd (and indexer, and indextool if you have one) somewhere. So if the new version fails. Can just restore these few
binary files back to the same place and revert to the old version).
BEWARE :
– you dont need the ‘mkdir’ step – because should have the folder already.
– you should stop the running instance of searchd you have now. To minimise downtime, just run ‘searchd –stop’ (and wait 20 seconds) just BEFORE ‘make install’ step.
– In theory the old sphinx.conf should work with the new version. But if searchd fails to start, do check searchd.log as well as the output when trying to start it.
