46 1 Stephan Schuberth
47 1 Stephan Schuberth
h3. Check installation
48 1 Stephan Schuberth
49 1 Stephan Schuberth
If this does not work, it is probably because there is no ruby at /usr/bin to be found. 
50 1 Stephan Schuberth
<pre>ruby -v</pre>
51 22 Stephan Schuberth
If it works, skip directly to "RubyGems 1.4.2".
52 22 Stephan Schuberth
53 1 Stephan Schuberth
54 6 Stephan Schuberth
h3. Fix dependencies
55 1 Stephan Schuberth
56 1 Stephan Schuberth
(Only in case _ruby -v_ is *NOT* working)
57 1 Stephan Schuberth
<pre>which ruby  # TO CHECK WHERE IT SHOULD BE
58 1 Stephan Schuberth
whereis ruby  # TO CHECK WHERE IT IS INSTALLED</pre>
59 1 Stephan Schuberth
_which_ returns like /usr/bin/ along with other directories (where ruby is expected to be), and _whereis_ returns like /usr/local/bin/ruby (thats where ruby actually lies).
60 1 Stephan Schuberth
61 6 Stephan Schuberth
h4. Fix via adding /usr/local/bin to $PATH
62 6 Stephan Schuberth
63 9 Stephan Schuberth
(Do this with your editor of choice, if you do not like nano.)
64 6 Stephan Schuberth
<pre>nano /etc/profile</pre>
65 6 Stephan Schuberth
66 6 Stephan Schuberth
Make the section with _pathmunge_ look alike like this:
67 6 Stephan Schuberth
<pre>#Path manupulation
68 6 Stephan Schuberth
if [ "$EUID" = "0" ]; then
69 6 Stephan Schuberth
    pathmunge /sbin
70 6 Stephan Schuberth
    pathmunge /usr/sbin
71 6 Stephan Schuberth
    pathmunge /usr/local/sbin
72 6 Stephan Schuberth
    pathmunge /usr/local/bin  # ADDED THIS
73 6 Stephan Schuberth
else
74 6 Stephan Schuberth
    pathmunge /usr/local/bin after  # ADDED THIS
75 6 Stephan Schuberth
    pathmunge /usr/local/sbin after
76 6 Stephan Schuberth
    pathmunge /usr/sbin after
77 6 Stephan Schuberth
    pathmunge /sbin
78 6 Stephan Schuberth
fi</pre>
79 6 Stephan Schuberth
80 6 Stephan Schuberth
OR ADD THIS AT THE END OF THE FILE:
81 6 Stephan Schuberth
82 6 Stephan Schuberth
<pre>nano /etc/profile
83 6 Stephan Schuberth
export PATH="$PATH:/usr/local/bin"</pre>
84 6 Stephan Schuberth
85 15 Stephan Schuberth
This sets the PATH for all Users beside root. For this setup you want to change the PATH for root, too:
86 6 Stephan Schuberth
87 6 Stephan Schuberth
<pre>nano ~/.bashrc
88 1 Stephan Schuberth
export PATH="$PATH:/usr/local/bin"</pre>
89 15 Stephan Schuberth
90 15 Stephan Schuberth
Logout your user and login again, to make the changes work.
91 6 Stephan Schuberth
92 6 Stephan Schuberth
h4. Fix via Symlink Creation 
93 6 Stephan Schuberth
94 42 Stephan Schuberth
This is not recommended, since if the ruby dependency is broken, others will likely be later on, too. Repair this by adding the folder to the $PATH variable like described before, else _gem_, _rake_, _bundle_, _passenger-install-apache2-module_ will not work either... you would have to create symlinks for them later on, too.
95 6 Stephan Schuberth
Symlinks are created like this
96 6 Stephan Schuberth
97 1 Stephan Schuberth
<pre>ln -s /usr/local/bin/ruby /usr/bin/ruby</pre>
98 6 Stephan Schuberth
99 8 Stephan Schuberth
h4. Verify ruby to be working
100 6 Stephan Schuberth
101 16 Stephan Schuberth
<pre>which ruby  # MUST RETURN PATH TO RUBY
102 16 Stephan Schuberth
ruby -v  # MUST RETURN RUBY VERSION
103 1 Stephan Schuberth
cd ..</pre>
104 16 Stephan Schuberth
105 19 Stephan Schuberth
Now it has to work. When changing $PATH variable, did you log out and log on again with your current user?
106 1 Stephan Schuberth
If this does not function properly, other things later on will also not work.

177 44 Alex Tremblay
Note: in some CentOS-like linux distros (RHEL, Amazon Linux) the C++ compiler does not come as part of the GCC compiler package. If that's the case, it can be installed with the following command:
178 44 Alex Tremblay
<pre>yum install gcc-c++</pre>
179 1 Stephan Schuberth
180 1 Stephan Schuberth
<pre>gem install passenger

230 13 Stephan Schuberth
231 13 Stephan Schuberth
h2. Create a MySQL database to use with Redmine
232 13 Stephan Schuberth
233 41 Stephan Schuberth
Start the mysql client:
234 41 Stephan Schuberth
<pre>mysql -u root -p</pre>
235 41 Stephan Schuberth
The version you have is shown in the welcome message.
236 41 Stephan Schuberth
Enter the following commands in the mysql console: (without repeating the prompt ;) )
237 41 Stephan Schuberth
<pre>mysql> create database redmine character set utf8;</pre>
238 25 Stephan Schuberth
239 13 Stephan Schuberth
h3. Latest MySQL Version
240 1 Stephan Schuberth
241 41 Stephan Schuberth
<pre>mysql> create user 'redmine'@'localhost' identified by 'my_password';
242 41 Stephan Schuberth
mysql> grant all privileges on redmine.* to 'redmine'@'localhost';
243 41 Stephan Schuberth
mysql> \q</pre>
244 1 Stephan Schuberth
245 1 Stephan Schuberth
h3. For versions of MySQL prior to 5.0.2
246 1 Stephan Schuberth
247 25 Stephan Schuberth
Skip the 'create user' step and do instead:
248 41 Stephan Schuberth
<pre>mysql> grant all privileges on redmine.* to 'redmine'@'localhost' identified by 'my_password';
249 41 Stephan Schuberth
mysql> \q</pre>
250 13 Stephan Schuberth
251 25 Stephan Schuberth
Now the database and a user to be used with it is created. Also the user has the rights to work on the database that was created.
252 13 Stephan Schuberth
253 25 Stephan Schuberth
h2. Configure database.yml 
254 13 Stephan Schuberth
255 29 Stephan Schuberth
There you have to enter the user:password combination (redmine:my_password) in the config file, so Redmine can actually talk to the database (redmine).
256 25 Stephan Schuberth
257 27 Stephan Schuberth
<pre>cd /var/www/redmine/config
258 28 Stephan Schuberth
cp database.yml.example database.yml
259 28 Stephan Schuberth
nano database.yml</pre>
260 1 Stephan Schuberth
261 27 Stephan Schuberth
Change it to look like:
262 27 Stephan Schuberth
<pre>production:
263 27 Stephan Schuberth
    adapter: mysql
264 27 Stephan Schuberth
    database: redmine
265 27 Stephan Schuberth
    host: localhost
266 27 Stephan Schuberth
    username: redmine
267 27 Stephan Schuberth
    password: my_password
268 27 Stephan Schuberth
    encoding: utf8</pre>
269 27 Stephan Schuberth
270 31 Stephan Schuberth
The other entries are not important, since we will use only the production environment. But if you would need the development or test environment, don't forget the create additional databases. *Don't* use the same database for production and testing or development environment!

h2. Set environment to "production" 
316 12 Stephan Schuberth
317 12 Stephan Schuberth
Rails has the concept of environments to represent the stages of an application’s lifecycle: test, development, and production by default. 
318 12 Stephan Schuberth
Specify your choice with the RAILS_ENV environment variable. 
319 12 Stephan Schuberth
Production has less verbose logging and is a bit faster, testing and development environment are not needed anyway for your Redmine.
