debug php 發現 上傳檔案異常 .....
先建立一個 test.php
<html> <body> <form action="upload.php" method="post" enctype="multipart/form-data"> 檔案名稱:<input type="file" name="file" id="file" /><br /> <input type="submit" name="submit" value="上傳檔案" /> </form> </body> </html>
PHP 檔案上傳後會先放到一個暫存資料夾(tmp),一般是放到 /tmp , 當然也可在 php.ini 設定 暫存資料夾
upload.php 內容如下 :
<?php if ($_FILES["file"]["error"] > 0){ echo "Error: " . $_FILES["file"]["error"]; }else{ echo "檔案名稱: " . $_FILES["file"]["name"]."<br/>"; echo "檔案類型: " . $_FILES["file"]["type"]."<br/>"; echo "檔案大小: " . ($_FILES["file"]["size"] / 1024)." Kb<br />"; echo "暫存名稱: " . $_FILES["file"]["tmp_name"]; } ?>
我測試了沒有 Error 發生 ....
然後程式改用 move_uploaded_file 將檔案移動到 upload 資料夾中
當然 upload 資料夾要有權限例如 apache 可 write
<?php if ($_FILES["file"]["error"] > 0){ echo "Error: " . $_FILES["file"]["error"]; }else{ echo "檔案名稱: " . $_FILES["file"]["name"]."<br/>"; echo "檔案類型: " . $_FILES["file"]["type"]."<br/>"; echo "檔案大小: " . ($_FILES["file"]["size"] / 1024)." Kb<br />"; echo "暫存名稱: " . $_FILES["file"]["tmp_name"]; move_uploaded_file($_FILES["file"]["tmp_name"],"upload/".$_FILES["file"]["name"]); } ?>
我測試了沒有 Error 發生 ....
但是 apache log 有 move_uploaded_file failed to open stream: Permission denied
且檔案沒有上傳到 upload 檔案夾內
搞了老半天 ....美編說 ...在我做 p2v 之前正常 ...
想了好久 ...原來是 .....之前人設單次的 SElinux DISABLE
啥 ........重開機後就有問題了, 之前裝完後都沒重開過 .......XD
SElinux DISABLE ....... 就這麼簡單 ....搞了半天
# cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
或許你覺得關閉 SElinux 不是一個好方式 將目錄改成 web 可存檔就好了呀 ...
# chcon -t httpd_sys_rw_content_t /var/www/upload -R
