让PHP访问/ dev / random的最佳方法是什么？

Question

My OwnCloud installation is complaining about not having access to /dev/random. OwnCloud will request multiple random numbers from different sources and derive from these the final random number, and /dev/random is one of these sources.

Is adding /dev/random to open_base_dir a good idea? Ive read somewhere that it's not recommended. Is there a better way to solve this?

Thanks all!

Answer 1

It's not a problem to add dev/urandom to open_base_dir and that will fix your ownCloud problem, but never add dev/random (without the u) as it can lack being fed enough entropy when generating the number.
