I need help porting the rc script for WozaMediaServer

G

Hi Guys

I have recently been trying to install WowzaMediaServer from the source because the port in the tree is both old, and unavailable as it requires a binary installer that has been removed.

The server itself works fine, but only when run in standalone mode, and there is no rc script provided that is compatible with FreeBSD.

I have been trying to modify the rc script provided with zero results but that is to be expected as this is the first time I have even looked inside an rc script. Below is the original, and them my work in progress, I am sure it is way off, but at least the paths are now correct, I know that much. :)

I have also tried using this as a template Porters Handbook, but I just made a mess.

If you have any advice for me that would be great :) Thanks for your time :)



Original rc script provided for CENTOS

Hi,

If your preferred route is to use the CentOS script then you would make your life easier by using Bash as the shell in FreeBSD too. As a quick fix, without looking too hard at the problem ;)
