Apache在ubuntu 18.04上安装了带有已安装映像目录的带有工件的映像 [英] Apache delivers images with artifacts on ubuntu 18.04 with mounted image directory

问题描述

我对通过apache2.4传递到Web浏览器的图片中的伪像有一个奇怪的问题.我们的comany使用中央图片存储存储所有产品图片.该目录安装在mnt/medamazonbild下的Web服务器中.我创建了一个符号链接，该链接指向img/artikel下的Web目录.这可以正常工作，并且该文件夹可以完全访问.

I have a strange issue with artifacts in pictures delivered via apache2.4 to the web browser. Our comany uses a central picture storage for all the product images. This directory is mounted into the webserver under mnt/medamazonbild. I created a symbolic link, which points into the web directory under img/artikel. This worked and the folder is fully accessible.

但是，一旦我通过chrome或firefox在目录下请求图片:

But as soon as I request a picture from the directory via chrome or firefox under:

172.17.1.27/img/artikel/70399.jpg

172.17.1.27/img/artikel/70399.jpg

输出附带工件.

出于测试目的，我尝试通过image.php中的PHP提供图像:

For test purposes I tried to deliver the image via PHP in image.php:

if (isset($_GET["img"])) {
    // get image name
    $img = filter_var($_GET["img"], FILTER_SANITIZE_STRING);

    // path of image with name and suffix
    $path = '/var/www/html/public/img/artikel/' . $img;

    header('Content-Type: image/jpeg');
    readfile($path);
}

结果是图像没有应有的伪像:

The result is the image without artifacts as it should be:

我不想用php处理所有图像的图像输出，因为我担心性能会下降. 如何获得针对Apache的解决方案，以按预期方式交付图像?错误在哪里?

I don't want to process the image output for all the images with php, because I'm afraid of performance decreases. How can I get a solution for apache to deliver the images as expected? Where is the error?

设置:

• Ubuntu 18.04 LTS
• Apache 2.4
• 安装目录，其图片位于:mnt/medamazonbild
• 从mnt/medamazonbild到webroot img/artikel的符号链接

推荐答案

我的图像上出现了相同类型的故障. 我使用的是官方docker image php:7.3-apache Docker Hub 为了解决这个问题，我在中添加了EnableSendfile on(我认为它的作用与您将其添加到httpd.conf中的作用相同)

I have the same type of glitchs on my images. I'm using the official docker image php:7.3-apache Docker Hub To fix this issue I added EnableSendfile on to my .htaccess (I think it works the same as if you add it in your httpd.conf)
