h2. Introduction
6
7 6 Hung Nguyen Vu
Our company was using the BITNAMI stack with Redmine and Subversion for our production environment. So the goal was about changing the server and migrating the data from Redmine 1.4 to Redmine 2.0.3 including getting all repositories and permissions preserved.

I've tried to avoid webrick but rather use the fastCGI Module for Apache2. 
10

12
Second was converting the built-in accounts from the database to LDAP (ActiveDirectory). This is the result of 2 days of work and googling is this little tutorial for setting up a mentioned box doing exactly this stuff. We are using CentOS 6 (i386) for that task.

# Please excuse my bad english for I am not used anymore to post long instruction manuals. Feel free to edit whatever you want. 
15
16
First of all, I tend to use vi so if you cannot operate vi I'd recommend to use any editor you like. If my instruction tells you to edit a file, you can find the sequence "..." which means, there is something above or below that line of text, that needs to be edited. Do not include those dots...

h2. Assumptions
19
20 2 Sven Nosse
* You have a CentOS 6.3 installation (minimum install) working and SSH access to your box
21 6 Hung Nguyen Vu
* You can access the Internet
22
* You are logged in as root

h2. Redmine Installation Instruction
25 2 Sven Nosse
26
My personal flavour is to use as less self compiled packages as necessary to get the package up and runnning. So I try to use as many repository packages as possible.
27
28 6 Hung Nguyen Vu
h3. Turn off SE-Linux
29 3 Sven Nosse
30 6 Hung Nguyen Vu
I spent a lot of time to find out, that selinux can be a real party pooper. So I strongly recommend to disable that first before installing anything else. You can find a tutorial inside the howto section describing how to enable SELinux for your installation.
31 2 Sven Nosse
<pre>
32
vi /etc/selinux/config
33
</pre>
34
35 1 Sven Nosse
find the line with SELINUX and set it to
36 2 Sven Nosse
<pre>
37
...
38
SELINUX=disabled
39
...
40
</pre>
41
Do a reboot *NOW*
42
43 6 Hung Nguyen Vu
h3. Install basic services (Apache, mySQL, and several tools...)
44 2 Sven Nosse
45 9 Hung Nguyen Vu
Now we are good to go to install some tools that might be useful during our installation... 
46
47
First of all, update your system, make sure it is up to date,
48 1 Sven Nosse
<pre>
49
yum update
50 9 Hung Nguyen Vu
</pre>
51
52
and then install some prerequisite packages to the setup,
53
<pre>
54
yum -y install wget vim \\
55
       system-config-network system-config-firewall vim openssh-clients
56
</pre>
57
58
anhd some packages needed for Redmine
59
<pre>
60 2 Sven Nosse
yum -y install httpd mysql mysql-server 
61 1 Sven Nosse
</pre>
62 2 Sven Nosse
After that continue and install all packages that might be necessary during the ruby and redmine installation.
63
<pre>
64
yum -y install ruby rubygems 
65 6 Hung Nguyen Vu
yum -y install zlib-devel curl-devel openssl-devel httpd-devel apr-devel apr-util-devel mysql-devel gcc ruby-devel \\
66
      gcc-c++ make postgresql-devel ImageMagick-devel sqlite-devel perl-LDAP mod_perl perl-Digest-SHA
67 2 Sven Nosse
</pre>
68
69
h3. Configure basic services
70
71 6 Hung Nguyen Vu
Let's configure the basic services, first of all, make mySQL and Apache to start at boot
72 2 Sven Nosse
<pre>
73
chkconfig httpd on --level 2345
74
chkconfig mysqld on --level 2345
75
</pre>
76
After configuring these, start them up
77
<pre>
78
service httpd start
79
service mysqld start
80
</pre>
81
Now configure your new mySQL Installation and follow the instructions. Please note the mysql administrator password.
82
<pre>
83
/usr/bin/mysql_secure_installation
84
</pre>
85
86
h3. Configure passenger for Apache
87
88
You need to install passenger for Apache using gem. Do the following on the command line
89
<pre>
90
gem install passenger
91
passenger-install-apache2-module
92
</pre>
93
Please notice the installation messages! The next .conf file might use another path or version! 
94
After this you need to generate a conf file with the displayed content
95
<pre>
96
vi /etc/httpd/conf.d/ruby.conf
97
</pre>
98
During my installation the following content was displayed and needs to be entered in that file:
99
<pre>
100
   LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.15/ext/apache2/mod_passenger.so
101
   PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.15
102
   PassengerRuby /usr/bin/ruby
103
</pre>
104
Restart your apache with
105
<pre>
106
service httpd restart
107
</pre>
108
109 1 Sven Nosse
h3. Get Redmine and install it
110
111
change to your home directory and download the latest version, expand it and copy it to the right place.
112
<pre>
113
cd
114
wget http://rubyforge.org/frs/download.php/76259/redmine-2.0.3.tar.gz
115
tar xvfz redmine-2.0.3.tar.gz
116 11 Hung Nguyen Vu
mkdir -p /var/www/redmine
117 12 Hung Nguyen Vu
cp redmine-2.0.3/* /var/www/redmine
118 1 Sven Nosse
</pre>
119 6 Hung Nguyen Vu
120
or you can do
121
122
<pre>
123
cd /var/www
124
wget http://rubyforge.org/frs/download.php/76259/redmine-2.0.3.tar.gz
125
tar xvfz redmine-2.0.3.tar.gz
126
ln -s redmine-2.0 redmine
127
</pre>
128
129 1 Sven Nosse
Next is to install bundler and let it install the production environment (with automatic resolve)
130
Now change to this directory - *this is your new Redmine application directory!*
131 2 Sven Nosse
<pre>
132
cd /var/www/redmine
133
gem install bundler
134
bundle install --without development test
135 1 Sven Nosse
</pre>
136 10 Hung Nguyen Vu
fetch some coffee... this might take some time...
137 2 Sven Nosse
138
h3. Create Redmine database
139
140 6 Hung Nguyen Vu
Next to generate a new database for redmine
141
Log on to your datbase with the following command. If prompted for a password, enter it.
142 2 Sven Nosse
<pre>
143
mysql -u root -p
144
</pre>
145
I tend to create a local only user for that database, change the password 'very_secret' to a better one :)
146
<pre>
147
create database redmine character set utf8;
148
create user 'redmine'@'localhost' identified by 'very_secret';
149
grant all privileges on redmine.* to 'redmine'@'localhost'; 
150
quit;
151
</pre>
152
153
h3. Configure Redmine
154
155
First of all, copy the example config to a productive one and edit the config for your needs
156
<pre>
157
cd /var/www/redmine/config
158
cp database.yml.example database.yml
159
vi /var/www/redmine/config/database.yml
160
</pre>
161
Now find the production section inside this file and edit it like that
162
<pre>
163
...
164
production:
165
  adapter: mysql
166
  database: redmine
167
  host: localhost
168
  username: redmine
169
  password: very_secret
170
  encoding: utf8
171
...
172
</pre>
173
Head back to your application directory and generate a secret token
174
<pre>
175
cd /var/www/redmine/
176
rake generate_secret_token
177
</pre>
178 1 Sven Nosse
Now it is about time to generate the database structure (application directory!)
179
<pre>
180 2 Sven Nosse
cd /var/www/redmine/
181
RAILS_ENV=production rake db:migrate
182
</pre>
183
fill the database with default values...
184 1 Sven Nosse
<pre>
185 2 Sven Nosse
cd /var/www/redmine/
186
RAILS_ENV=production rake redmine:load_default_data
187
</pre>
188
follow the instructions to select your language.
189
190 6 Hung Nguyen Vu
h3. Mind the firewall!
191 2 Sven Nosse
192 6 Hung Nguyen Vu
Be aware that the firewall is enabled by default (which is good!). So if you know which ports to open, do it now or disable the firewall (just for testing purposes). I'd really recommend disabling the firewall during installation and enable it (opening ports) after you are sure that everything works.
193 1 Sven Nosse
<pre>
194 2 Sven Nosse
system-config-firewall
195
</pre>
196
use the onscreen menu to disable it or adjust the values.
197
198 8 Hung Nguyen Vu
or simply disable iptables during Redmine's setup
199
<pre>
200
service iptables stop
201
</pre>
202
203 6 Hung Nguyen Vu
h3. Do a testdrive!
204 2 Sven Nosse
205
I mentioned that I wanted not to use webrick, but for a testdrive, it'll work. This helps finding bugs and errors that might have occured before.
206
<pre>
207
cd /var/www/redmine/
208
ruby script/rails server webrick -e production
209
</pre>
210
Open up a browser and point it to: http://yoursystemname.yourdomain.com:3000 - the default username and password is 'admin'.
211
If everything is working, you are good to go! Kill webrick by hitting Ctrl+C.
212
213 6 Hung Nguyen Vu
h3. Activate FCGI and generate plugin directory
214 2 Sven Nosse
215
To activate the fcgi module you need to copy the example file and edit the very first line. During this step it is recommended to generate the default .htaccess config as well.
216
<pre>
217
cd /var/www/redmine/public
218
mkdir plugin_assets
219
cp dispatch.fcgi.example dispatch.fcgi
220
cp htaccess.fcgi.example .htaccess
221 1 Sven Nosse
vi /var/www/redmine/public/dispatch.fcgi
222
</pre>
223 2 Sven Nosse
now edit dispatch.fcgi and change it like this...
224
<pre>
225
#!/usr/bin/ruby
226
...
227
</pre>
228
229
h3. Apache permissions!
230
231
this one is important, so don't miss that one... 
232 1 Sven Nosse
<pre>
233 2 Sven Nosse
chown -R apache:apache /var/www/redmine/
234 1 Sven Nosse
</pre>
235 2 Sven Nosse
236 6 Hung Nguyen Vu
Note: "apache" is the user that runs httpd (apache) service, as defined in /etc/password and /etc/httpd/conf/httpd.conf 
237
238 2 Sven Nosse
h3. Getting Apache to work with FastCGI
239
240
Unfortunately the default Repo from CentOS cannot deliver the fcgid module so it is important to include a replo, that can deliver this package. I use the Fedora Repo so it is time to activate this... Again - this can change so please take care which repository to use.
241
<pre>
242
rpm --import https://fedoraproject.org/static/0608B895.txt
243
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm
244
rpm -ivh epel-release-6-7.noarch.rpm
245
yum -y install mod_fcgid
246
</pre>
247
248 6 Hung Nguyen Vu
h3. Set the file path for Redmine
249 2 Sven Nosse
250
I wanted to move the files to another location, so I decided to move them to /opt/redmine
251
<pre>
252 6 Hung Nguyen Vu
mkdir -p /opt/redmine/files
253 2 Sven Nosse
chown -R apache:apache /opt/redmine
254
</pre>
255
now edit the configuration
256
<pre>
257
cd /var/www/redmine/config
258
cp configuration.yml.example configuration.yml
259
vi /var/www/redmine/config/configuration.yml
260
</pre>
261
edit the path settings inside this file...
262
<pre>
263
...
264
  attachments_storage_path: /opt/redmine/files
265
...
266
</pre>
267
268
h3. Telling Apache to serve REDMINE
269
270
The final step is to tell apache, where to find Redmine and what to do with it. Generate a new conf file for your virtual host to serve redmine...
271
<pre>
272
vi /etc/httpd/conf.d/redmine.conf
273
</pre>
274
and enter the following config (adjust to your needs ;) )
275
<pre>
276
<VirtualHost *:80>
277
        ServerName yoursystemname.yourdomain.com
278
        ServerAdmin yourmail@yourdomain.com
279
        DocumentRoot /var/www/redmine/public/
280
        ErrorLog logs/redmine_error_log
281
282
        MaxRequestLen 20971520
283
284
        <Directory "/var/www/redmine/public/">
285
286
                Options Indexes ExecCGI FollowSymLinks
287
                Order allow,deny
288
                Allow from all
289
                AllowOverride all
290
        </Directory>
291
</VirtualHost>
292
</pre>
293
Restart Apache and cross your fingers, wheter you can access http://yoursystemname.yourdomain.com - redmine should be available right now...
294
<pre>
295
service httpd restart
296
</pre>
297
298
h3. Additional Config: E-Mail System
299
300 1 Sven Nosse
in order to get emails sent to your clients, edit the configuration.yml and enter your server settings...
301
<pre>
302
vi /var/www/redmine/config/configuration.yml
303
</pre>
304
now find the settings for your server... the following settings describe an anonymous relay on an internal server. You need to remove the username and password line if you use anonymous sign on.
305
<pre>
306
...
307
default:
308
  # Outgoing emails configuration (see examples above)
309
  email_delivery:
310
    delivery_method: :smtp
311
    smtp_settings:
312
      address: mailserver.yourdomain.com
313
      port: 25
314
      domain: yourdomain.com
315
...
316
</pre>
317
318 6 Hung Nguyen Vu
Here is the configration if you use Google's SMTP server
319
320
<pre>
321
production:
322
  email_delivery:
323
    delivery_method: :smtp
324
    smtp_settings:
325
#      tls: true
326
      enable_starttls_auto: true
327
      address: "smtp.gmail.com"
328
      port: '587'
329
      domain: "smtp.gmail.com"
330
      authentication: :plain
331
      user_name: "google-account-name@domain-name.domain-extension"
332
      password: "password"

h2. Getting Subversion working
337 2 Sven Nosse
338
After getting Redmine working, it is time to get Subversion working... The goal is to integrate the repositories inside Redmine and host them on the same server...
339
340
h3. Installing Packages for Subversion
341
342
Install the following packages
343 1 Sven Nosse
<pre>
344 2 Sven Nosse
yum -y install mod_dav_svn subversion subversion-ruby
345
</pre>
346
347
h3. Linking authentication for Redmine
348
349
Redmine provides a perl module to handle Apache authentication on SVN DAV repositories. First step is to link that module into the search path
350
<pre>
351
mkdir /usr/lib/perl5/vendor_perl/Apache
352
ln -s /var/www/redmine/extra/svn/Redmine.pm /usr/lib/perl5/vendor_perl/Apache/Redmine.pm
353
</pre>
354
355 6 Hung Nguyen Vu
h3. Creating repository for subversion
356 2 Sven Nosse
357
create a path and set permissions for your SVN repo...
358
<pre>
359
mkdir /opt/subversion
360
chown -R apache:apache /opt/subversion
361
</pre>
362
363 6 Hung Nguyen Vu
h3. Edit virtual host for apache to serve SVN with redmine
364 2 Sven Nosse
365
to get Apache working with subversion, you need to adjust (create) the virtual host file
366
<pre>
367
vi /etc/httpd/conf.d/subversion.conf
368
</pre>
369
now enter/edit the following
370
<pre>
371
PerlLoadModule Apache::Redmine
372
<Location /svn>
373
        DAV svn
374
        SVNParentPath "/opt/subversion"
