HowTo to handle SVN repositories creation and access control with Redmine¶
- HowTo to handle SVN repositories creation and access control with Redmine
This setup is not required if you just need to browse your repositories and changesets from Redmine.
As of version 0.5.0, Redmine is able to handle Subversion repositories creation and access control.
Once you’ve done this extra setup, Redmine will create the repository for each of your projects. Users will be allowed to access the repositories using ssh+svn, according to their permissions defined in Redmine :
- for public projects : read access to the repository for any user, write access for project members only,
- for private projects : read/write access allowed to project members only.
User authentication is done using the same login/password as for Redmine access.
You need Redmine 0.5.0 or higher, running with MySQL1.Your SVN repositories must be hosted on a *nix system with the following packages:
- pam_mysql 0.7pre2 or higher, compiled with SHA1 support
Scripts used in this HowTo can be found in the /extra/svn directory of Redmine.In this HowTo, we assume that:
- the redmine database is called
redmineand hosted on
- the Subversion repositories are located in
The SVN host must be able to access both the Redmine database and HTTP server(s). In many cases, they will all be located on the same host.
Installing requires packages¶
Get nss_mysql and other necessary packages:
apt-get install build-essential libnss-mysql libpam0g-dev libssl-dev
Get and build
$ cd /usr/src $ wget http://prdownloads.sourceforge.net/pam-mysql/pam_mysql-0.7RC1.tar.gz $ tar xzf pam_mysql-0.7RC1.tar.gz $ cd pam_mysql-0.7RC1 $ ./configure --with-openssl $ make && make install
Preparing the Redmine database¶
Some views need to be added to the Redmine database. These views are used to authenticate users and retrieve their permissions.
1. Create the different views in your Redmine database :
mysql --user=root redmine -p < create_views.sql
2. Create and grant privileges to 2 new mysql users (
mysql --user=root -p mysql> create user redmine_nss@localhost identified by 'averylongpassword'; mysql> grant SELECT on redmine.nss_groups to redmine_nss@localhost; mysql> grant SELECT on redmine.nss_users to redmine_nss@localhost; mysql> grant SELECT on redmine.nss_grouplist to redmine_nss@localhost; mysql> create user redmine_pam@localhost identified by 'averylongpassword'; mysql> grant SELECT on redmine.ssh_users to redmine_pam@localhost;
3. Create the /etc/nss-mysql.conf as follows:
conf.version = 2; users.host = inet:localhost:3306; users.database = redmine; users.db_user = redmine_nss; users.db_password = averylongpassword; users.backup_database = nss_mysql_backup; users.table = nss_users; users.user_column = nss_users.username; users.userid_column = nss_users.username; users.uid_column = nss_users.uid; users.gid_column = 100; users.realname_column = nss_users.realname; users.homedir_column = "/false/path"; users.shell_column = "/usr/local/bin/svnserve.wrapper"; groups.group_info_table = nss_groups; groups.group_name_column = nss_groups.name; groups.groupid_column = nss_groups.gid; groups.gid_column = nss_groups.gid; groups.password_column = "x"; groups.members_table = nss_grouplist; groups.member_userid_column = nss_grouplist.username; groups.member_groupid_column = nss_grouplist.gid;
4. Install the svnserve wrapper
sudo install svnserve.wrapper /usr/local/bin
5. Change /etc/nsswitch.conf
Add “mysql” at the end of the two lines passwd and group like that :
passwd: compat mysql group: compat mysql
6. Test that all this stuff works :
You must have users in some project to verify.
% getent passwd [...] user1:x:5002:100:user1 user1:/false/path:/usr/local/bin/svnserve.wrapper user2:x:5003:100:user2 user2:/false/path:/usr/local/bin/svnserve.wrapper % getent group [...] project1:x:5001: project2:x:5002:
Authorize ssh pam to use mysql¶
7. Add these lines in
auth sufficient pam_mysql.so \ verbose=1 \ user=redmine_pam \ passwd=averylongpassword \ host=localhost \ db=redmine \ table=ssh_users \ usercolumn=username \ passwdcolumn=password crypt=4 account sufficient pam_mysql.so \ verbose=1 \ user=redmine_pam \ passwd=averylongpassword \ host=localhost \ db=redmine \ table=ssh_users \ usercolumn=username \ passwdcolumn=password crypt=4 password sufficient pam_mysql.so \ verbose=1 \ user=redmine_pam \ passwd=averylongpassword \ host=localhost \ db=redmine \ table=ssh_users \ usercolumn=username \ passwdcolumn=password crypt=4
8. Test this against an existing Redmine user
Try to connect to the SVN host using a Redmine username (eg. jsmith):
$ ssh jsmith@localhost jsmith@localhost's password: Could not chdir to home directory /false/path: No such file or directory ( success ( 1 2 ( ANONYMOUS EXTERNAL ) ( edit-pipeline ) ) )
The chdir error is the expected result.
Automating repository creation¶
Repository creation can be automated by running periodically the reposman script.
It takes 2 arguments:
svn-dir: path to the directory where your svn repositories are located
redmine-host: host name of your Redmine install
Perl and Ruby versions of this script are provided. The Perl version requires
Example using the Ruby version:
$ sudo ./reposman.rb --svn-dir=/var/svn --redmine-host=localhost repository /var/svn/project2 created repository /var/svn/project1 created mode change on /var/svn/project3
Projects are retrieved from Redmine using a SOAP web service. This web service is disabled by default in Redmine.
To enable it, go to “Administration -> Settings” and check Enable WS for repository management.
With a recent version of redMine/reposman.rb (re. 860 and later), reposman.rb can register the new repository
in redMine so that you have nothing to do and set the owner of repository to who you want to allow browsing private
repository in redMine. For more information see HowTo advanced subversion and redMine integration.
Make sure this option is checked if you get this error when running reposman:
Service description 'http://localhost/sys/service.wsdl' can't be loaded: 404 Not Found
Accessing the repositories¶
You can now access project1 repository using this url:
1 Other databases can’t be used because of various problems: no pam module, no sha1 handling,...
