5 | 4 | Jean-Philippe Lang | h2. Overview |
6 | 1 | Nicolas Chuche | |
7 | 23 | Eric Davis | In this documentation, we will configure apache to delegate authentication to mod_perl. It's tested on apache2 (@apache2-mpm-prefork@) with mysql and postgresql but should work with allmost every databases for which there is a perl DBD module. Apache2 with the high speed thread model might not load Perl correctly (@apache2-mpm-worker@). |
8 | 1 | Nicolas Chuche | |
9 | You need a working apache on your SVN server and you must install some modules at least mod_dav_svn, mod_perl2, DBI and DBD::mysql (or the DBD driver for you database as it should work on allmost all databases). |
||
10 | 4 | Jean-Philippe Lang | |
11 | 15 | Jean-Philippe Lang | On Debian/ubuntu you can do : |
12 | 11 | Shaun Mangelsdorf | |
13 | 15 | Jean-Philippe Lang | sudo aptitude install libapache2-svn libapache-dbi-perl libapache2-mod-perl2 libdbd-mysql-perl libdigest-sha1-perl |
14 | 1 | Nicolas Chuche | |
15 | 15 | Jean-Philippe Lang | If the repositories are not created automatically by reposman.rb, it is important that the repository name is the same as the project identifier in Redmine, otherwise Redmine.pm will fail to authenticate users. |

17 | h2. Enabling apache modules |
||
18 | |||
19 | On debian/ubuntu : |
||
20 | |||
21 | <pre> |
||
22 | 15 | Jean-Philippe Lang | sudo a2enmod dav |
23 | 21 | Marko Roeder | sudo a2enmod dav_svn # if you want to use svn |
24 | sudo a2enmod dav_fs # if you want to use git |
||
25 | 15 | Jean-Philippe Lang | sudo a2enmod perl |

28 | 15 | Jean-Philippe Lang | h2. Apache configuration for Subversion repositories |
29 | 1 | Nicolas Chuche | |
30 | 15 | Jean-Philippe Lang | You first need to copy or link @Redmine.pm@ to @/usr/lib/perl5/Apache/Redmine.pm@ |
31 | Then add the following Location directives to your apache configuration (for example in @/etc/APACHE_DIR/conf.d/@): |
||
32 | 1 | Nicolas Chuche | |
33 | 17 | Joachim Fritschi | * the old how-to which suggested two separate locations for with @/svn@ and @/svn-private@ can be avoided |
34 | * with the @Satisfy any@ keyword from Apache you can define different authentication policies |
||
35 | * read access from the redmine-server or any validated user |
||
36 | * write access only validated users |

||
79 | |||
80 | 17 | Joachim Fritschi | h3. Testing the configuration: |
81 | 1 | Nicolas Chuche | |
82 | 17 | Joachim Fritschi | After reloading apache conf, you can try to browse some repository with: |
83 | |||
84 | 1 | Nicolas Chuche | <pre> |
85 | svn ls http://my.svn.server/svn/myproject |
||
86 | 4 | Jean-Philippe Lang | </pre> |
87 | 1 | Nicolas Chuche | |
88 | 17 | Joachim Fritschi | Any non-public repository should ask for a username and password. |
89 | 4 | Jean-Philippe Lang | |
90 | 17 | Joachim Fritschi | To test the authentication that allows you redmine server to read all repositories: |
91 | 1 | Nicolas Chuche | |
92 | 17 | Joachim Fritschi | Reading a private repository: |
93 | 3 | Jean-Philippe Lang | <pre> |
94 | 17 | Joachim Fritschi | svn ls http://my.svn.server/svn/myproject |
95 | </pre> |
||
96 | Try writing to the repository: |
||
97 | <pre> |
||
98 | svn mkdir http://my.svn.server/svn/myproject/testdir |
||
99 | </pre> |
||
100 | This should fail and ask for a password. |
||
101 | |||
102 | |||
103 | h3. optional LDAP Authentication |
||
104 | |||
105 | If you want to connect your LDAP authentication to Apache, you can install the Authen::Simple::LDAP perl module. I found that connecting to my LDAP server to authenticate with every request can be quite slow. I added the following to my configuration and had a significant performance increase. If you have configured an encrypted connection to the LDAP server you will need the IO::Socket::SSL module. |
||
106 | |||
107 | 20 | Stefan Stefansson | > *NOTE: the above wording is a little confusing. I attempt to clear up the issues I had with this in the following paragraph.* |
108 | > |
||
109 | > First of all, make sure that you have the Net::LDAP module installed as well. I installed Authen::Simple::LDAP through CPAN and found that nothing worked. Eventually I figured out that this was because the Authen::Simple::LDAP did not require the Net::LDAP module as a dependency but it is needed for our purpose here. I did this on CentOS and it seems that the Net::LDAP module can be installed via yum (@yum install perl-LDAP@) but the Authen::Simple::LDAP had to be installed via CPAN since there's no RPM for it in the CentOS repositories. |
||
110 | > |
||
111 | > My second point is related to the below Apache config. The @PerlLoadModule Authen::Simple::LDAP@ is actually not required for having users authenticated via LDAP. It will happen automatically if both of the above modules are installed. So there really is no difference between the config snippet below and the one above except for the @RedmineCacheCredsMax 50@ line which is probably a good idea although it can result in users that have been deleted or removed in redmine still getting access to the repositories, at least for a little while. |

141 | 15 | Jean-Philippe Lang | h2. Apache configuration for Git repositories |
142 | |||
143 | Now that reposman.rb can create git repositories, you can use Redmine.pm to access them the same way than subversion. |
||
144 | 8 | Nicolas Chuche | |
145 | You first need to copy or link Redmine.pm to /usr/lib/perl5/Apache/Redmine.pm, then you add this configuration to apache : |
||
146 | |||
147 | <pre> |
||
148 | 9 | Nicolas Chuche | Alias /git /var/git |
149 | 8 | Nicolas Chuche | |
150 | PerlLoadModule Apache::Redmine |

151 | <Location /git> |

157 | |||
158 | PerlAccessHandler Apache::Authn::Redmine::access_handler |
||
159 | PerlAuthenHandler Apache::Authn::Redmine::authen_handler |
||
160 | |||
161 | RedmineDSN "DBI:mysql:database=redmine;host=localhost" |
||
162 | RedmineDbUser "redmine" |
||
163 | RedmineDbPass "password" |
||
164 | </Location> |
||
165 | |||
166 | Alias /git-private /var/git |
||
167 | |||
168 | <Location /git-private> |
||
169 | Order deny,allow |
||
170 | Deny from all |
||
171 | <Limit GET PROPFIND OPTIONS REPORT> |
||
172 | Options Indexes FollowSymLinks MultiViews |
||
173 | Allow from 127.0.0.1 |
||
174 | </Limit> |
||
175 | </Location> |
||
176 | </pre> |
||
177 | |||
178 | To verify that you can access repository through Redmine.pm, you can use curl : |
||
179 | <pre> |
||
180 | % curl --netrc --location http://localhost/git/ecookbook/HEAD |
||

183 | |||
184 | 22 | Diego Oliveira | h2. Apache configuration for Mercurial repositories |
185 | |||
186 | Create a file caled "hgweb.config" in the same folder as "hgwebdir.cgi". This foder will be the root repository folder. Then edit the "hgweb.config" with something like this: |
||
187 | |||
188 | <pre> |
||
189 | [paths] |
||
190 | /=/path/to/root/repository/** |
||
191 | |||
192 | [web] |
||
193 | allow_push = * |
||
194 | allowbz2 = yes |
||
195 | allowgz = yes |
||
196 | allowzip = yes |
||
197 | |||
198 | </pre> |
||
199 | |||
200 | Follows the instructions to install Redmine.pm as described and configure your apache like this. |
||
201 | |||
202 | <pre> |
||
203 | RewriteEngine on |
||
204 | PerlLoadModule Apache2::Redmine |
||
205 | PerlLoadModule Authen::Simple::LDAP |
||
206 | ScriptAliasMatch ^/hg(.*) /path/to/the/hgwebdir.cgi/$1 |
||
207 | <Location /hg> |
||
208 | AuthType Basic |
||
209 | AuthName "Mercurial" |
||
210 | Require valid-user |
||
211 | |||
212 | #Redmine auth |
||
213 | PerlAccessHandler Apache::Authn::Redmine::access_handler |
||
214 | PerlAuthenHandler Apache::Authn::Redmine::authen_handler |
||
215 | RedmineDSN "DBI:mysql:database=redmine;host=localhost" |
||
216 | RedmineDbUser "DB_USER" |
||
217 | RedmineDbPass "DB_PASSWD" |
||
218 | </Location> |
||
219 | </pre> |

222 | 13 | Thomas Pihl | h2. Gotchas |
223 | |||
224 | If you run this in Phusion Passenger, make sure you don't turn PassengerHighPerformance on. If you do, the rewrites to catch subversion dav will be bypassed with some interesting dump in the log as a result. |
||
225 | Example: |

227 | (if your repo are named rm-code) |
