Trying to install Trac on CentOS 5
James Lampert
Last week, I was able to figure out how to get SVN up and running, first through Apache, and eventually through svnserve.
But now that I've turned my attention to Trac, I'm a bit stymied. Yum couldn't find it, and I couldn't make head or tail of the instructions for registering RPMforge (which appears to be deprecated anyway). I then found instructions for doing it with "easy_install," and got as far as installing easy_install itself, but it blew up when I tried to install TRAC (and unfortunately, what I know about Python wouldn't buy you a cup of coffee):
[root@localhost ~]# easy_install Trac
Searching for Trac

As I said, what I know about Python (or easy_install, for that matter) wouldn't buy you a cup of coffee. To quote a line from a certain David Hedison movie, "Helllllpppppp meeeeeeee!!!!"

Centos5's default python is very old. If you can do this on something newer you'll have a much easier time of it. Pretty sure Trac past 1.0 requires at least python 2.7.

Also the error message should be better, but looks like a recent change is giving unexpected behavior when installing into an unsupported Python version:

- Simply replacing the system Python breaks Yum, and probably breaks a few other things.
- There's a whole bunch of subtly different procedures for getting Python 2.7 onto CentOS 2.7 side-by-side with the existing 2.4.3.

CentOS 5 is rather old. Can you use CentOS 7?

RPMS, they didn't interfere/overlap with the system Python. They worked
fine for us.
Unfortunately IUS migrated their RHEL 5 repo to their Archives so the
setup isn't so straightforward now. They have an "ius-release" RPM for
RHEL 5 in the Archives but the mirror list doesn't work, so you have to
hand-hack it after installing it.
If James installs the following:
https://dl.iuscommunity.org/pub/ius/archive/Redhat/5/$basearch/ius-release-1.0-15.ius.el5.noarch.rpm
(Substitute "i386" or "x86_64" for $basearch first, obvs.)
then you can go into "/etc/yum.repos.d" and massage the
"ius-archive.repo" file it installs - enable "baseurl" and comment out
"mirrorlist". It should end up looking like this:
--
[ius-archive]
name=IUS Community Packages for Enterprise Linux 5 - $basearch - Archive
baseurl=http://dl.iuscommunity.org/pub/ius/archive/Redhat/5/$basearch

At that point you should be able to do a "yum list python27" and install
it from there. (They also have python31 RPMs for 3.1 as well.)

to that, update your repo and install it from there.
If not, use "rpm" directly:
rpm -ivh
https://dl.iuscommunity.org/pub/ius/archive/Redhat/5/i386/ius-release-1.0-15.ius.el5.noarch.rpm
or
rpm -ivh
https://dl.iuscommunity.org/pub/ius/archive/Redhat/5/x86_64/ius-release-1.0-15.ius.el5.noarch.rpm
whichever is appropriate for your architecture (or both).
If you have further issues we should probably take this off-line.
