|
||||
|
||||
Redmine - a mod_perl module to authenticate webdav subversion users
|
||||
against redmine database
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
This module allow anonymous users to browse public project and
|
||||
registred users to browse and commit their project. authentication is
|
||||
done on the redmine database.
|
||||
|
||||
This method is far simpler than the one with pam_* and works with all
|
||||
database without an hassle but you need to have apache/mod_perl on the
|
||||
svn server.
|
||||
|
||||
=head1 INSTALLATION
|
||||
|
||||
For this to automagically work, you need to have a recent reposman.rb
|
||||
(after r860) and if you already use reposman, read the last section to
|
||||
migrate.
|
||||
|
||||
Sorry ruby users but you need some perl modules, at least mod_perl2,
|
||||
DBI and DBD::mysql (or the DBD driver for you database as it should
|
||||
work on allmost all databases).
|
||||
|
||||
On debian/ubuntu you must do :
|
||||
|
||||
aptitude install libapache-dbi-perl libapache2-mod-perl2 libdbd-mysql-perl
|
||||
|
||||
=head1 CONFIGURATION
|
||||
|
||||
## if the module isn't in your perl path
|
||||
PerlRequire /usr/local/apache/Redmine.pm
|
||||
## else
|
||||
# PerlModule Apache::Authn::Redmine
|
||||
<Location /svn>
|
||||
DAV svn
|
||||
SVNParentPath "/var/svn"
|
||||
|
||||
AuthType Basic
|
||||
AuthName redmine
|
||||
Require valid-user
|
||||
|
||||
PerlAccessHandler Apache::Authn::Redmine::access_handler
|
||||
PerlAuthenHandler Apache::Authn::Redmine::authen_handler
|
||||
|
||||
## for mysql
|
||||
PerlSetVar dsn DBI:mysql:database=databasename;host=my.db.server
|
||||
## for postgres
|
||||
# PerlSetVar dsn DBI:Pg:dbname=databasename;host=my.db.server
|
||||
|
||||
PerlSetVar db_user redmine
|
||||
PerlSetVar db_pass password
|
||||
</Location>
|
||||
|
||||
To be able to browse repository inside redmine, you must add something
|
||||
like that :
|
||||
|
||||
<Location /svn-private>
|
||||
DAV svn
|
||||
SVNParentPath "/var/svn"
|
||||
Order deny,allow
|
||||
Deny from all
|
||||
# only allow reading orders
|
||||
<Limit GET PROPFIND OPTIONS REPORT>
|
||||
Allow from redmine.server.ip
|
||||
</Limit>
|
||||
</Location>
|
||||
|
||||
and you will have to use this reposman.rb command line to create repository :
|
||||
|
||||
reposman.rb --redmine my.redmine.server --svn-dir /var/svn --owner www-data -u http://svn.server/svn-private/
|
||||
|
||||
=head1 MIGRATION FROM OLDER RELEASES
|
||||
|
||||
If you use an older reposman.rb (r860 or before), you need to change
|
||||
rights on repositories to allow the apache user to read and write
|
||||
S<them :>
|
||||
|
||||
sudo chown -R www-data /var/svn/*
|
||||
sudo chmod -R u+w /var/svn/*
|
||||
|
||||
And you need to upgrade at least reposman.rb (after r860).
