installation commands
 

Hi
i dont have MAN page on my solaris
what kind of help does solaris use
How do i install
an application on solaris like Mysql or bind or apache
in linux i use rpm
what command do i use in solaris

That is likely because you didn't choose a developer or a full installation.
manual pages are the primary source of documentation.
You can browse all Solaris documentation including manual pages on http://docs.sun.com
bind and apache are usually already installed (although perhaps not with your machine as you have a limited installation).
pkgadd (System V standard command)
pkg-get (a wrapper to pkgadd which handles dependancies à la apt-get).
pkg (very new, experimental command found in the Open Solaris Indiana preview).

thank i tried that but an erro came up saying
pkgadd: eeror: no package were found in </var/spool/pkg>
i also check that folder and its empty

Indeed.
You need to specify the location where the package to be installed is present. Those bundled with the O/S are on the installation media (CD or DVD), otherwise, you'll need to download the package from some repository like sunfreeware or blastwave.

how do i copy them from my Cd or DVD to my computer to install

brilliant question..... need to think abt it actually man

copy from CD/DVD is simple thing ...mount the cd and use 'cp' command to copy the file in ur hdisk

Actually, there is no need to copy the files from the CD/DVD to the local disk, you can just install from there. You can also install remote packages as pkgadd supports http URLs.

ok thanks do i use the same addpkg command or do i have to point to the cd for it to install it from there

The pkgadd manual page will tell you the command supports options like "-d" which will be useful in that case.
