'./configure'  '--prefix=/usr/local/php' '--with-config-file-path=/usr/local/php/etc' '--enable-fpm' '--with-fpm-user=www' '--with-fpm-group=www' '--with-mysql=/usr/local/mysql' '--with-mysql-sock=/tmp' '--with-libxml-dir' '--with-gd' '--with-jpeg-dir' '--with-png-dir' '--with-freetype-dir' '--with-iconv-dir' '--with-zlib-dir' '--with-mcrypt=/usr/local/libmcrypt' '--enable-soap' '--enable-gd-native-ttf' '--enable-ftp' '--enable-mbstring' '--enable-exif' '--disable-ipv6' '--with-pear' '--with-curl' '--with-openssl'

Loaded Configuration File :none

实在没有办法，只能使用strace去追踪一下：
strace  /usr/local/php/bin/php -i 2> /tmp/1.log
grep 'php.ini' /tmp/1.log 显示如下信息：
open("/usr/local/php/bin/php.ini", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/lib/php.ini", O_RDONLY) = -1 ENOENT (No such file or directory)
write(1, "Configuration File (php.ini) Pat"..., 33) = 33


此时，发现问题，php竟然去/usr/local/php/bin/ 下去找php.ini了。
这是为什么呢？ 暂时我还无法解释，之后问题就容易解决了，直接把 php.ini 拷贝至/usr/local/lib即可
