PHP文件上传 - 内存不足

Question

I have a Symfony application using Sonata admin and Sonata media my client uses to upload mp4 videos. The problem is these files are getting bigger and bigger (> 1go) and I now have trouble with "out of memory" apache errors.

The website is hosted on an AWS EC2 ubuntu instance (PHP, Apache2). I set the php.ini parameters like this:

upload_max_filesize = 1G
post_max_size = 2G
memory_limit = -1

I did this for cli and apache2 under /etc/php/7.0/. I tried various combinations and higher values. Always restart apache afterwards. I even tried rebooting the instance. I can't get to upload more than 350mo.

Answer 1

OK, I found a solution. Here's how I did it.

First of all, i stopped my EC2 instance, detached the volume and made a snapshot of it.

From the snapshot, I created a bigger volume (30Go for now). I reattached it to my EC2 instance, which I rebooted.

I logged in through SSH and installed a swapspace (3Go). Tweaked it a little following this.

I cleant the cache, restarted my EC2 instance one last time and... well I just uploaded 1Go in 20 minutes.

One issue though : stopping and starting my EC2 instance I lost my IP and had to change my DNS zone. It's gonna take a few hours for the website to be back...

Hope this will be helpful to someone.
