php安装完成以后要复制php.ini文件
直接 #find / -name php.ini 找不到，是因为安装php的时候没有复制配置文件 php版本变化以后ini文件名有变 php.ini-production 对应于php.ini-recommended php.ini-development 对应于php.ini-dist 二者差异？ 由于版本更新,这些文件有了新的命名: php.ini-p
直接
#find / -name "php.ini"
找不到，是因为安装php的时候没有复制配置文件
php版本变化以后ini文件名有变
php.ini-production对应于php.ini-recommended
php.ini-development对应于php.ini-dist
二者差异？
由于版本更新,这些文件有了新的命名:
php.ini-production对应于php.ini-recommended
php.ini-development对应于php.ini-dist
通常要将php.ini-dist或php.ini-recommended重命名为php.ini。
根据说明，二者不同之处在于 php.ini-dist 适合开发程式使用（测试用），
而 php.ini-recommended 拥有较高的安全性设定，则适合上线当产品使用。
我一般将php.ini-recommended或者新的php.ini-production修改为php.ini，确保测试环境（本地）与正式环境（线上）一致。
需要回到php安装目录
#cp php.ini-recommended /usr/local/php/lib/php.ini
或者
#cp php.ini-production /usr/local/php/lib/php.ini
