Setup SVN on SUSE

Prerequisites

Apache 2
Neon Library
Subversion Client

Installation

Prerequisites Installation

1.    Install Apache 2
2.    Install neon from first DVD, libneon27-0.29.6-6.7.1.x86_64.rpm
3.    Get Subversion Server and Client Binaries
4.    Install SubVersion Client first, and then Subversion Server

Subversion Installation

Change folder to where Subversion Server binary placed

# rpm -ivh subversion-server-1.6.17-51.1.x86_64.rpm

After Subversion installation, you should be able to find below file placements:

# rpm -ql subversion-server-1.6.17-51.1.x86_64
/etc/apache2/conf.d
/etc/apache2/conf.d/subversion.conf
/usr/lib64/apache2
/usr/lib64/apache2/mod_authz_svn.so
/usr/lib64/apache2/mod_dav_svn.so

Configuration

Configure Apache 2

1. Apply below changes in /etc/sysconfig/apache2

APACHE_MODULES="authz_host actions alias auth_basic authz_groupfile authn_file authz_user autoindex cgi dir include log_config mime negotiation setenvif status userdir asis dav dav_fs imagemap php5 perl python dav_svn authz_svn authz_default ssl"

< APACHE_SERVER_FLAGS="SSL"

2. SSL Enablement

Creating a “Dummy” Certificate

Generating a dummy certificate is simple. Just call the script /usr/bin/gensslcert. It creates or overwrites the following files:

    /etc/apache2/ssl.crt/ca.crt
    /etc/apache2/ssl.crt/server.crt
    /etc/apache2/ssl.key/server.key
    /etc/apache2/ssl.csr/server.csr

A copy of ca.crt is also placed at /srv/www/htdocs/CA.crt for download.

Apply below changes to /etc/apache2/vhosts.d/vhost-ssl.conf (copy it from vhost-ssl.template if it doesn't exist)
Comment out below line:
SSLProtocol all -SSLv2 -SSLv3


Restart Apache2 and test both secure and non-secured connection.
