in log

Class 'Memcache' not found

in console I run memcache, but still app die. what need to do check ?

Sorry, I am a bit confused. "app dies", what app? Does PHP crash? Do you get any error logs? Is the only thing that causes the crashing is when you add that single line? — Iskar

Thanks for the edit! Is the PHP extension for memcache installed and loaded? Just having memcache system daemon doesn't give the ability to use new Memcache;. There are a lot of questions regarding that error message, do you get any resolution when searching on them? eg stackoverflow.com/q/2659035 — Iskar

I solved this problem when sudo pecl install pecl_http-2.5.5 because need php version 5.6 and then in php info I find memcache and memcached — shuba.ivan

Memcache and Memcached are two different libraries.

Your php info says you have installed memcached. Error says you are using memcache.

Try installing memcache and you should be fine.
