如何防止PHP寫入具有權限644的配置文件？

Question

我安裝的應用程序報告它能夠寫入配置文件，並且我應該將權限更改爲644或444.權限當前爲644.該文件由擁有所有權的相同用戶擁有網絡文件（我用於FTP和SSH的同一用戶）不是root用戶，所以如果我擁有權限444，我將無法以任何方式修改文件，除非獲得root訪問權限。 （這不是我的服務器，所以我不得不要求這個。）我的問題是，如果644意味着只有所有者可以寫入文件，PHP如何能夠寫入文件？我聽說過諸如suPHP之類的東西，它們使您能夠以與指定用戶相同的權限運行PHP。我在命令行運行「php -i」並搜索「suPHP」，但什麼也沒找到。這是或多或少完全轉儲：

Answer 1

如果您正在使用Apache作爲Web服務器，大多數時候它使用www數據的用戶編寫的文件，但並非總是如此。

ps aux | grep httpd 

檢查運行apache的用戶，也許它是該文件夾的所有者。

Answer 2

要找出用戶腳本運行的（這在一般情況下並不一定相同文件的所有者），你可以檢查的輸出：如果該用戶是

$user_info = posix_getpwuid(posix_geteuid()); 
echo $user_info['name']; 

根運行速度快，遠離您當前的主機。

但它可能不是。

如果返回的用戶與文件所有者（您通過ssh等登錄的用戶）相同，chmod配置文件爲400 - 不需要它是世界可讀的。如果它是不同的用戶chmod 444。

當您需要修改文件：

1. chmod u+w your.file來設置用戶可寫位。 （如果你擁有的文件，你可以做這即使該文件是隻讀的。）
2. 做修改。
3. chmod u-w your.file刪除可寫位。

_{（chmod u+w相同chmod 600或chmod 644，取決於開始的權限，而u-w逆轉它。）}
