根据PHPinfo：

加载配置文件：/etc/PHP5/fpm/PHP.ini

# grep expose_PHP /etc/PHP5/fpm  -R
    /etc/PHP5/fpm/PHP.ini:expose_PHP = Off
    /etc/PHP5/fpm/pool.d/www.conf:PHP_flag[expose_PHP] = off

# curl -I https://MyHost.loc/i.PHP | head | grep X-Powered-By
X-Powered-By: PHP/5.5.9-1ubuntu4

有人可以在Ubuntu 14.04中确认这一点吗？

知道如何摆脱X-Powered-By？
