Well... there is little to say here, it suffices to go to a site that holds the files and download them. There is only a small remark to make: if you use Windows and download a version comprised of a file with the ending tar.gz, do not worry, your Winzip supports it without problems. Once downloaded, extract it and "throw" all its contents in a folder you created for this purpose and you call "Nuke5" or whatever ( sites from which you can download PHP-Nuke are: phpnuke.org, www.spaghettibrain.com etc.).
Well, now what remains is just to upload the files to the interior of our main server directory that resides on our provider.
Don't upload all extracted files. After extraction, you will find a structure similar to the one depicted in Figure 5-1.
This process only really applies if your PHP-Nuke will be installed on a Linux/Unix server, if instead you will install it on Windows operating systems you don't have to do anything.
Setting up permissions on files serves the purpose of having them execute only certain operations (write, execute etc.) when called. Setting them up correctly is important for PHP-Nuke to operate in its full functionality.
The permissions to give are the following (for the base permissions, see Section 10.1 in the context of security):
With WS_FTP you must select the files or folders on which you want to impose the permissions and, with the right mouse key, to select the option CHMOD.
Once you set up the permissions on all folders and all files, this procedure will cost you some time, but it is very important to carry out. Moreover, you will have to do it every time you insert a new file or module to your PHP-Nuke.
