Setup SVN with apache web-frontend authenticating LDAP active directory on AIX. (SVN + Apache + LDAP)

SVN (subversion) is widely use all over the world. Last week I had to setup some SVN repositories on AIX server.
Here’s what I did:
1- Download and install subversion subversion-1.8.5-1.src.rpm from http://www.perzl.org/aix/index.php?n=Main.Subversion
Take into account install all these dependencies for subversion rpm package:

svn_dependencies

Apache web server can be easily installed following this steps:

http://wp.me/p5bweg-3k

Find all details of these dependencies here http://www.perzl.org/aix/index.php?n=Main.Subversion

 

 

After install all dependencies, install subversion rpm file.


aix# rpm -ivh subversion-1.8.5-1.aix5.3.ppc.rpm

2- Apache server (httpd) was already installed before, because it was a dependency of subversion rpm package.
Verify if apache server is installed:

aix# rpm -qa|grep http
httpd-2.2.17-4

3- Create your new SVN repository on a directory or a new filesystem.

aix # svnadmin create /PATH/MYREPO/MYREPO

4- Change apache as owner of this directory or filesystem.

aix # chown -R apache:apache /PATH/MYREPO/MYREPO

5- Verify permission of your repository directory.

aix # ls -l /PATH/MYREPO/MYREPO
total 32
-rw-------    1 apache   apache          229 May 19 13:11 README.txt
drwx------    2 apache   apache          256 May 19 13:11 conf
drwx--S---    6 apache   apache         4096 May 19 13:11 db
-r--------    1 apache   apache            2 May 19 13:11 format
drwx------    2 apache   apache         4096 May 19 13:11 hooks
drwx------    2 apache   apache          256 May 19 13:11 locks

6- Setup apache’s configuration files for subversion.

First, let’s configure apache’s  main file /opt/freeware/etc/httpd/conf/httpd.conf


aix# cat /opt/freeware/etc/httpd/conf/httpd.conf

# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/httpd/foo_log"
# with ServerRoot set to "/opt/freeware/etc/httpd" will be interpreted by the
# server as "/opt/freeware/etc/httpd//var/log/httpd/foo_log".

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "/opt/freeware/etc/httpd"

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
#
PidFile /var/run/httpd.pid

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 80

#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#

# LoadModule foo_module modules/mod_foo.so

# Supplemental configuration
#
# The configuration files in the conf/extra/ directory can be

# the server, or you may simply copy their contents here and change as
# necessary.

# Server-pool management (MPM specific)
#Include conf/extra/httpd-mpm.conf

# Multi-language error messages
Include conf/extra/httpd-multilang-errordoc.conf

# Fancy directory listings
#Include conf/extra/httpd-autoindex.conf

# Language settings
Include conf/extra/httpd-languages.conf

# User home directories
#Include conf/extra/httpd-userdir.conf

# Real-time info on requests and configuration
#Include conf/extra/httpd-info.conf

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

# Local access to the Apache HTTP Server Manual
#Include conf/extra/httpd-manual.conf

# Distributed authoring and versioning (WebDAV)
# Include conf/extra/httpd-dav.conf

# Various default settings
Include conf/extra/httpd-default.conf

# Secure (SSL/TLS) connections
Include conf/extra/httpd-ssl.conf
#
# Note: The following must must be present to support
#       starting without SSL on platforms with no /dev/random equivalent
#       but a statically compiled-in mod_ssl.
#
<IfModule ssl_module>
SSLRandomSeed startup builtin

</IfModule>
# Subversion settings
Include conf/extra/httpd-subversion.conf

7- Setup apache as web-frontend for subversion. File /opt/freeware/etc/httpd/conf/extra/httpd-subversion.conf has to be edited.

aix# cat /opt/freeware/etc/httpd/conf/extra/httpd-subversion.conf

# Load the Subversion (SVN) modules
#
LoadModule dav_svn_module     /opt/freeware/lib/httpd/modules/mod_dav_svn.so
LoadModule authz_svn_module   /opt/freeware/lib/httpd/modules/mod_authz_svn.so

# My repository
     <Location /myrepo>
      Dav svn
      SVNPath /PATH/MYREPO/MYREPO
      AuthType Basic
      AuthName "SVN-LDAP-Auth"
      AuthBasicProvider ldap
      AuthzLDAPAuthoritative on
      AuthLDAPBindDN "bind_user_for_ldap@domain.net"
      AuthLDAPBindPassword "passwd"
      
### You can use this other ldap config.
###   AuthLDAPURL "ldap://dcdomain.net:389/OU=MYOU,DC=domain,DC=net?sAMAccountName?sub?(objectClass=*)" or the below:
      AuthLDAPURL "ldap://dcdomain.net:3268/?sAMAccountName?sub?"
      AuthUserFile /dev/null
      Require ldap-user israel
    </Location>
#

7- Verify  if apache’s syntax is correctly.

aix# /opt/freeware/sbin # ./apachectl -t

8- Start apache server.

aix # /opt/freeware/sbin/apachectl start
9- Connect from a browser or any SVN client like Tortoise (http://tortoisesvn.net/)
http://MYSVN_server/myrepo

10- See Apache’s logs.
All logs from apache are in this directory or filesytem /var/syslog/httpd/

aix#  ls -ltr /var/syslog/httpd/
total 7573696

Hope this helps.

Just thanks if the post was helpful 🙂
