修改PHP 加载loaded configuration file 目录

在/usr/local/php/etc/目录下新建php2.ini

复制php.ini 内容到php2.ini 或cp php.ini 也行。

配置php-fpm 参数：

Usage: php [-n] [-e] [-h] [-i] [-m] [-v] [-t] [-p <prefix>] [-g <pid>] [-c <file>] [-d foo[=bar]] [-y <file>] [-D] [-F]
  -c <path>|<file> Look for php.ini file in this directory
  -n               No php.ini file will be used
  -d foo[=bar]     Define INI entry foo with value 'bar'
  -e               Generate extended information for debugger/profiler
  -h               This help
  -i               PHP information
  -m               Show compiled in modules
  -v               Version number
  -p, --prefix <dir>
                   Specify alternative prefix path to FastCGI process manager (default: /usr/local/php).
  -g, --pid <file>
                   Specify the PID file location.
  -y, --fpm-config <file>
                   Specify alternative path to FastCGI process manager config file.
  -t, --test       Test FPM configuration and exit
  -D, --daemonize  force to run in background, and ignore daemonize option from config file
  -F, --nodaemonize
                   force to stay in foreground, and ignore daemonize option from config file
  -R, --allow-to-run-as-root
                   Allow pool to run as root (disabled by default)

　　

其中：-c

<path>|<file> Look for php.ini file in this directory

指定ini文件的目录

所以：

php-fpm -c /usr/local/php/etc/php2.ini

重启nginx是查看没有改变！

service nginx reload

要重启php-fpm

但是提示：

ERROR: An another FPM instance seems to already listen on /tmp/php-cgi.sock
ERROR: FPM initialization failed

所以先停止php-fpm 服务在指定php.ini 文件

/etc/init.d/php-fpm stop

php-fpm -c /usr/local/php/etc/php2.ini 

--------------------------------------------------------------------------------------------------------

隐藏X-Powered-By

则修改 php.ini 文件 设置 expose_php = Off

记得重启是重启php-fpm 而不是nginx，重启php-fpm ， 如果修改了php.ini配置目录还要重新-c 配置ini目录
