F12 Need Advice on sw installation

[tasikputri]

Hi Friends,

I'm new in Linux and I'm still learning from u guys.

Previously, I'd installed my system with F10. Following some of friends in FedoraForum, I'd upgraded my system with fresh installation to F12.

Now, I want to install PostgreSQL and JBOSS in my system.
I want it to be installed in /Sal/PostgreSQL and /Sal/jboss for easy maintenance.

How do I specify Yum install to install the sw into the folder that i want.

If it is better to be installed in the standard directory(what is it- /etc??),
pls kindly advice and give me the pro's and con's.

TQ

If you will install it via yum - there willn't be any problems with maintenance.
Also, package install files into several dirs. /etc is for configuration files .You can see what files are installed by running
rpm -ql packagename
(it will work only if package is already installed)

Most software in Fedora will be installed in the /usr directory. Why would you want to install software to a different directory? I guess with respect to updates, it will be less troublesome to stick with the default.

It is for my own maintenance. I want to group all the sw related to my system altogether in one folder.

Or is it possible in the /usr directory, I specify (before yum install the folder I want my related sw to be parked.

TQ in adv

If you want to use non-standard filesystem layout, you can't use the standard Fedora tools for maintaining your software packages. You must build everything from sources (http://www.linuxfromscratch.org/).

This is not true - he can create something like chroot environment using

yumdownloader --destdir=/tmp fedora-release
rpm --root /tmp -ivh --nodeps /tmp/fedora-release*rpm
yum install --installroot=/tmp postgresql
But i don't think that it will go far from default way.

Keldron....what do u mean? Is it possible for me to do it.
What do u suggest? Or better for me to stick with the default path.

I'm hoping for the best advice....hu...hu....:(I'm totally new in linux. For windows this can be done. I want to migrate my system for Windows to Linux.....

In my opinion, its better to stick with the default installation directories, since it will cause less trouble with future updates and if you plan to upgrade to a newer release.

I am agree withCSchwangler. The default path is the best variant for a maintance.
I have showed you how to do what you want without building packages from sources - but you will ned to run them in chroot inveronment. (It is not always easy and it is done for a security reasons, not for maintenance)
Aftrer you have installed application you should start them in chroot environment... something like
chroot /tmp /usr/bin/postgresql start

Hi guys.....sorry my my long silent. TQ for the advice.But when I try to download the sw I'm having this problem :
[root@sal /]# yum update
Loaded plugins: presto, refresh-packagekit
fedora | 2.9 kB 00:00
http://download.fedoraproject.org/pub/fedora/linux/releases/12/Everything/i386/os/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for fedora: Damaged repomd.xml file
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again

Can I just copy repomd.xml from my other machine and replaced it on the machine that is having this update problem.

[tasikputri]
