I covered svn setup on media temple dv and similar centos with plesk setups here : http://elsid.net/2007/05/07/setup-svn-server-on-media-temple-dv-or-centos-with-plesk/

Now i’ll cover the basics of setting up trac on media temple dv and similar centos with plesk setups. Please note this is what worked for me (and should work for other media temple dv setups). Please let me know if i missed something, or any recommendations.

first steps

First you need to request root access and the developer tools package. Once that’s done we’re ready to start.

This setup will use mysql for the trac database and serve trac from a subdomain. I’m only covering the setup of a vanilla trac installation

You can take a look at the trac install guide here : http://trac.edgewall.org/wiki/TracInstall

Preq’s / What you’ll need:

clear silver :

setup tools :

mysqldb:

python:

mod_python:

svn:

More pre-install steps

I covered svn setup here : http://elsid.net/2007/05/07/setup-svn-server-on-media-temple-dv-or-centos-with-plesk/

svn must be rebuilt to work correctly with trac. http://trac.edgewall.org/ticket/3706#comment:10 .

First we need to edit the svn makefile.
change : SVN_APR_LIBS = /root/subversion-1.4.3/apr/libapr-0.la -lrt -lm -lcrypt -lnsl -lpthread -ldl
to : SVN_APR_LIBS = /root/subversion-1.4.3/apr/libapr-0.la -lrt -lm -lcrypt -lnsl -lpthread -ldl -L/usr/lib -lgssapi_krb5 -lkrb5 -lk5crypto
replace /root/subversion-1.4.3 with what ever is the path in your file.

now run make clean, then make, and make install

Almost done. We’ll build swig and then move to our trac setup. in your subversion build folder do the following.

make swig-py
make install-swig-py
make swig-py install

If you’ve installed all the preq’s, rebuilt svn, and built swig we should be ready to install trac.

–note : you may need to copy the svn and libsvn folder from /usr/local/lib/svn-python to /usr/lib/python/site-packages. remember copy not move.

Install trac

Install Trac
python ./setup.py install

Setup Project

go to plesk and setup a subdomain for trac. Make sure you only select python support.

now setup a mysql database at the same domain you made your trac subdomain at. Add a user for this database and we’re almost home.

make the following directorys :
/var/www/vhosts/yourdomain/subdomains/yoursubdomain/trac/test
/var/www/vhosts/yourdomain/subdomains/yoursubdomain/svn/test

setup a project : trac-admin /var/www/vhosts/yourdomain/subdomains/yoursubdomain/trac/test initenv

setup a test svn for this project : svnadmin create /var/www/vhosts/yourdomain/subdomains/yoursubdomain/svn/test

make a sub directory in our trac directory and chmod 0777 it, we’ll need this later: mkdir /var/www/vhosts/yourdomain/subdomains/yoursubdomain/trac/plugins
chmod 0777 /var/www/vhosts/yourdomain/subdomains/yoursubdomain/trac/plugins

be sure to check the permissions on your svn and trac directory, we need to be sure apache is able to access and run our files.

go to the conf directory for your subdomain : cd /var/www/vhosts/yourdomain/subdomains/yoursubdomain/conf

almost done make a file : vhost.conf

Open this file and add the following, remember to fix the paths to your domain and subdomain:

SetEnv PYTHON_EGG_CACHE /var/www/vhosts/yourdomain/subdomains/yoursubdomain/trac/plugins
SetHandler mod_python
PythonHandler trac.web.modpython_frontend
PythonOption TracEnv /var/www/vhosts/yourdomain/subdomains/yoursubdomain/trac/test
PythonOption TracUriRoot /
PythonInterpreter main_interpreter

Final Steps

restart apache : /usr/local/psa/admin/sbin/websrvmng -a -v

point your browser to your trac subdomain. If everything is working fine you’ll see a trac page. If not you’ll see a 500 error page.

Got Problems?

If your seeing an error page you should take the following steps:

go to plesk >> yourdomain >> log manager >> error log

copy the portion that contains your error and remove the servers timestamps and ip data.

do a google on the very last line, this will contain the error message. You’ll likely see a result from the trac website. if not add the word trac before your search.

If you still see no results from the trac website, go to the site and search the tickets. Still no luck? open a new ticket. Trac is very good with support and the community is extremely helpful.

If you need help you can contact me, but i’d recommend using the trac community as i’m not fluent with python.

happy coding – sid

I’m saving this here for my ref:

This walk through covers setting up a svn server on media temples dedicated virtual servers (dv) or similarly configured centos with plesk installations.

With media temple the yum command isn’t available so we have to do it the long way

first go to http://subversion.tigris.org/project_packages.html

Download the source for both subversion and dependencies. make sure you download them both to the same directory

you can do this using wget, ex : wget file_location

ok now extract both archives – use google if you don’t know how

almost done, now lets get it installed

first cd (change directory) into the subversion folder, then run the following commands

./configure --with-apxs=/usr/sbin/apxs
make
make install

This will configure with apache support, build and install. now all thats left is setting up apache and a domain, but before we get to it, check your httpd.conf file and make sure you see the following modules being loaded :

mod_dav_svn mod_authz_svn

I prefer to use a subdomain and recommend it, ex: trac.domain = trac frontend, svn.domain=regular svn access. It’s up to you. the steps for setting up a subdomain and domain are pretty much the same, so i’ll only cover subdomains.

Login to plesk, select the domain you plan on using. go to subdomains > add new

ok here we want to setup a new subdomain. remember to give this subdomain a different ftp account that the main site.

save this domain, check that it’s up and running , and exit plesk.

almost done

login to your servers file system go to /var/www/vhosts/your_domain/subdomains/your_subdomain/

now we need to setup a svn repo.
first make a new directory for our repo , I recommend making it your subdomains dir, ex

mkdir /var/www/vhosts/your_domain/subdomains/your_subdomain/svn/repo;
chmod 0777 /var/www/vhosts/your_domain/subdomains/your_subdomain/svn/repo;
svnadmin create /var/www/vhosts/your_domain/subdomains/your_subdomain/svn/repo;

next cd into your conf directory at /var/www/vhosts/your_domain/subdomains/your_subdomain/conf

vi vhost.conf

and enter :

#svn.server.com — vhost.conf file
<location />
DAV svn
SVNPath /var/www/vhosts/your_domain/subdomains/your_subdomain/svnrepo
AuthType Basic
AuthName “Subversion Repository”
AuthUserFile /etc/svn-auth-file
Require valid-user
</location>

ok promise it’s almost over

We need to add a user for access via the apache svn frontend

htpasswd -c /etc/svn-auth-file your_user

now run
/usr/local/psa/admin/sbin/websrvmng -a -v

That restarts apache to load all of our changes.

now go to your_subdomain.your_domain and login – svn is running

Things to keep in mind, I’m only covering media temple dv, and similar centos with plesk configurations. I’m not covering security, i’ve not covering trac, getting your repo setup, etc. So this is a vanilla install. – use google and make it more.
