在Ubuntu系统中配置PHP文件上传路径，可以按照以下步骤进行：
首先，你需要修改PHP的配置文件php.ini。这个文件通常位于/etc/php/{version}/apache2/php.ini或/etc/php/{version}/cli/php.ini，具体取决于你使用的是Apache还是CLI模式。
php.ini文件sudo nano /etc/php/{version}/apache2/php.ini
将{version}替换为你的PHP版本号，例如7.4。
找到以下配置项并进行修改：
upload_max_filesize = 10M
post_max_size = 10M
file_uploads = On
upload_tmp_dir = /tmp
upload_max_filesize：设置单个文件的最大上传大小。post_max_size：设置整个POST请求的最大大小。file_uploads：启用文件上传功能。upload_tmp_dir：设置上传文件的临时存储目录。确保上传目录存在并且PHP有写权限。
sudo mkdir -p /var/www/uploads
sudo chown www-data:www-data /var/www/uploads
sudo chmod 755 /var/www/uploads
如果你使用的是Apache，确保你的虚拟主机配置允许上传文件。
sudo nano /etc/apache2/sites-available/your-site.conf
添加或修改以下内容：
<Directory /var/www/html>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
<Directory /var/www/uploads>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
将/var/www/html替换为你的网站根目录。
sudo systemctl restart apache2
创建一个简单的PHP脚本来测试文件上传功能。
sudo nano /var/www/html/upload.php
添加以下内容：
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$target_dir = "/var/www/uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is an actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
}
?>
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
在浏览器中访问http://your-server-ip/upload.php，尝试上传一个文件来测试配置是否成功。
通过以上步骤，你应该能够在Ubuntu系统上成功配置PHP文件上传路径。
