apc.ini

会社のCentOS6にapcを導入した。導入方法は検索すればいくらでもでてくるので取り扱わない。ただ、CentOS5の場合/etc/php.d/配下にapc.iniをつくらなければならない。

色々なサイトを見て回ってるが、apc.iniのディレクティブ関連がapc.shm_sizeとextension = apc.soだけしかなかったりとこれでは色々不十分みたいだ。

3.1.9これがCentOS6と同じバージョンなんでいっそapc.iniコピペしてもいいかもしれん。

; requested on your web server. Set to zero or omit if you are not sure;
apc.num_files_hint=1024

; variables to store.  Set to zero or omit if you are not sure;

apc.filters
; The mktemp-style file_mask to pass to the mmap module
