This is a cookbook for a SubVersion (aka svn) installation on debian and apache2 with LDAP integration authentication.

1. Install subversion

# apt-get install subversion

# mkdir /var/lib/svn
# svnadmin create /var/lib/svn/repos
# chown www-data:www-data /var/lib/svn/repos/ -R

3. Install Apache2

# apt-get install apache2

4. Set apache2 modules

# apt-get install libapache-mod-ldap libapache-auth-ldap libapache2-svn

If needed enable modules


# a2enmod ldap
# a2enmod auth_ldap

5. Setup Apache2 website
• Create folder

# mkdir /var/www/svnwebsite

• Create website configuration file usually in /etc/apache2/sites-available

NameVirtualHost svnserver.dev
<VirtualHost svnserver.dev>
   ServerAdmin webmaster@localhost

DocumentRoot /var/www/svnserver

<Directory />
   Options Indexes FollowSymLinks MultiViews
   Order allow,deny
   allow from all

   ### LDAP AUTHENTICATION SPECIFICS
   # Do not check other data besides LDAP
   AuthLDAPAuthoritative on
   # Do basic password authentication in the clear
   AuthType Basic
   # The name of the protected area or “realm”
   AuthName “SVN”
   # AD requires an authenticating DN to access records
   AuthLDAPBindDN “cn=user,ou=Users,dc=domain
   # This is the password for the AuthLDAPBindDN user in AD
   AuthLDAPBindPassword “password”
   # The LDAP query URL
   AuthLDAPURL “ldap://ldapserver:389/ou=Users,dc=domain
   #authorization
   require valid-user
</Directory>

<Location /repos >
  DAV svn
  SVNParentPath /var/lib/svn/
  AuthzSVNAccessFile /etc/apache2/dav_svn.authz

Here are the basic steps to install another wordpress weblog on a multiple web sites infrastructure over apache2 on debian.

1. Create the new database

In order to pick a consistent database name, check the existing databases and create a new one. Then create a new username and give it full access.

mysql> show databases;
mysql> create database <databasename>;
mysql> select User, Password, Host from user;
mysql> grant all privileges on <databasename>.* to <username>@<hostname> identified by “<password>”;
mysql> flush privileges;
mysql> exit;

2. Setup the wp-config file

#copy wp-config.php to config-<website>.php

Update config-website.php constants with the info from above.

define(’DB_NAME’, ‘<databasename>’); // The name of the database
define(’DB_USER’, ‘<username>’); // Your MySQL username
define(’DB_PASSWORD’, ‘<password>’); // …and password
define(’DB_HOST’, ‘<hostname>’); // 99% chance you won’t need to change this value

3. Setup Apache2 web site

Create a website path

#ln -s /usr/share/wordpress /var/www/<website>

Create logs folder

#mkdir /var/log/apache2/<website>

Create a new apache configuration file for the website

/etc/apache2/sites-available/<website>

<VirtualHost *:80>
        ServerName <website>
        ServerAdmin webmaster@<domain>

        DocumentRoot /var/www/<website>/
        <Directory /var/www/<website>>
                Options …

                # hack for nice URIs
                <IfModule mod_rewrite.c>
                        RewriteEngine On
                        RewriteBase /
                        RewriteCond %{REQUEST_FILENAME} !-f
                        RewriteCond %{REQUEST_FILENAME} !-d
                        RewriteRule . /index.php [L]
                </IfModule>

        </Directory>
        …
        LogLevel warn
        ErrorLog /var/log/apache2/<website>/error.log
        CustomLog /var/log/apache2/<website>/access.log combined
        …
</VirtualHost>

#a2ensite website

#/etc/init.d/apache2 reload
