====== php-fpm pool ======
php-fpmのpool機能を利用して、apacheのsuExec相当のWebサーバのユーザIDとは異なるユーザIDでCGIを実行する。
===== /usr/local/etc/php-fpm.conf =====
<code>
include=/usr/local/etc/php-fpm.d/*.conf
[global]
emergency_restart_threshold 10
emergency_restart_interval 1m
process_control_timeout 10s
events.mechanism = kqueue

</code>
===== /usr/local/etc/php-fpm.d/*.conf =====
<code>
# cat /usr/local/etc/php-fpm.d/hoge.conf

[hoge]                                         <= 環境に合わせる
listen = /var/run/php-fpm-hoge.sock            <= 環境に合わせる(socksまたはIP:port <- poolごとにportを変える)
listen.mode = 0666
user = hoge                                    <= 環境に合わせる

2016.02.07 listen.modeを書かないとエラーになる。前は大丈夫だったんだが…
