PHP 5.2.8

I've tried to install with .zip, tar etc format..
I've change the file permision to 777 /component, tmp/ images

Hello,

Your MySQL server has gone away, try to re-install kunena by putting kunena in /tmp and launch the install from this directory.

You should increase MySQL timeout to around 180 seconds and try again. Copying files takes a long time and MySQL should be nice and keep waiting during that time.

I didnot find the way to increase mysql timeout in this forum. Can you direct me about it?

It has nothing to do with Joomla or Kunena. It's a server setting. Please ask it from your service provider.
