Version Control & Packaging

The general, the software version in CentOS are behind. It's just the way CentOS and Red Hat operate. They aim for long term support and stability.

But if you have to use a newer software package, you may find the some newer packages in CentOS's test repository, as listed in this page Available Repositories for CentOS. For CentOS 5 testing packages, you can find them in http://dev.centos.org/centos/5/testing/.

How do I yum install SRPM from CentOS/Red Hat site, instead of manually download the srpm from one of the ftp website?

Install yum-utils

# yum install yum-utils

Get the dependency

If the package is already installed, use "rpm -qR <package-name>" to get the list of packages that this package depends on. For example:

$ rpm -qR openldap

If the package is not yet installed, use "yum  deplist <package-name>" to get the list of packages that this package depends on. For example:

Prepare GPG key

Create the repository

This will show you how to create the repository over http.

First create directory structure on the server, say server1:

[root@server1 ~]# mkdir -p /var/www/repo/CentOS/4/local/i386/RPMS

If createrepo is not already installed, as it will not be by default, install it.

Installation

To install the Git version control system on a Gentoo server, follow the steps below:

The book "Rails Cookbook" has a wonderful section on "Getting Your Rails Project into Subversion".

In short, here are the steps:

Subversion supports symbolic link, as stated in http://subversion.tigris.org/. Here is the quote:  

it's simple to test this. In a directory where you have svn code checked out, do

% ln -s file file_link
% svn add file_link
% svn ci
