symlink tool to pull together rpm components in one place

equick · 03-01-2012, 04:31 AM

Hi, is there a tool, a bit like the opposite of stow, which can link together all components of an rpm under one prefix? So for example, I would like to use fedora's version of apache but want to prefix this under /usr/local/myapache, so httpd would be in /usr/local/myapache/sbin/httpd (as a symlink to /usr/sbin/httpd).

Thanks for any help.

Ed.

There is the root option to rpm that install a package under the given root directory. Maybe this can help. AFter install you only would need to make a symlink. I guess you also have to install the rpm that apache depends on inside the new root but not sure about that.

Thanks for your reply. I'll give that a go, but from other posts I've read that requires a chroot'd install.

Why would you want to do that? Why go against package management and the FSSTND, LFS and other such standards? If you want everything in one place you could install using "--relocate". 'man rpm' for more.

Why? Because I don't wish to change the existing apache config files for all my sites. I have a directory set up like

Code:

/opt/apache/server
/opt/apache/server/bin/httpd
/opt/apache/server/modules
/opt/sites/site1/bin/apachectl
/opt/sites/site1/conf/httpd.conf

So ideally I would like to install the httpd rpm into /opt/apache/server

I tried --relocate as a test but got the following error:

Code:

rpm --force --install --relocate /usr=/home/ed/httpd httpd-2.2.17-1.fc14.i686.rpm
path /usr in package httpd-2.2.17-1.fc14.i686 is not relocateable

Can you see what I'm doing wrong?

Thanks.

This link sheds some light: http://www.cyberciti.biz/faq/rpm-relocatable-packages/

If you don't have to use php or similar stuff you could compile apache your self. Just for the case that relocation or prefixing does not work.

Thanks for the link. It was useful. The upshot is you can't use rpm to install fedora httpd into a prefixed location as it's not a relocatable rpm.

I'm really looking for a tool which is like the opposite to stow (stow symlinks prefixed software into the standard places). One way might be to write a bash script to list the contents of an rpm and symlink the contents to a prefixed location. My question is just asking if there is already something that does this?

I dunno of any tool like that.
