Work today because the PHP environment is also compiled after reinstalling the Debian system, there is no Redis extension installed.
Download a Redis 2.2.8 compilation from the official website by installing, php-m can see everything OK
Running the program is always provided rediscluster can not be re-declared to carefully check only one include, our own Rediscluster class, and then I put this line commented out do not prompt this error, the hint Rediscluster must have a parameter, Just pass in a parameter, and there is a fault in the operation.
From the official website of a Redis 2.2.7 from the new compilation, everything is normal.
I don't know if Reids 2.2.8 contains a class called Rediscluster, which causes conflicts with custom class names, and is hereby recorded!
PHP redis2.2.7 extension Bug results in segment failure and re-declaring class bugs
