h3. Untar
36 1 Stephan Schuberth
37 1 Stephan Schuberth
<pre>tar zxvf ruby-1.8.7.pXXX.tar.gz</pre>
38 1 Stephan Schuberth
39 1 Stephan Schuberth
h3. Install
40 1 Stephan Schuberth
41 1 Stephan Schuberth
<pre>cd ruby-1.8.7.pXXX
42 1 Stephan Schuberth
./configure
43 1 Stephan Schuberth
make
44 1 Stephan Schuberth
make install</pre>
45 1 Stephan Schuberth
46 1 Stephan Schuberth
h3. Check installation
47 1 Stephan Schuberth
48 1 Stephan Schuberth
If this does not work, it is probably because there is no ruby at /usr/bin to be found. 
49 1 Stephan Schuberth
<pre>ruby -v</pre>
50 22 Stephan Schuberth
If it works, skip directly to "RubyGems 1.4.2".
51 22 Stephan Schuberth
52 1 Stephan Schuberth
53 6 Stephan Schuberth
h3. Fix dependencies
54 1 Stephan Schuberth
55 1 Stephan Schuberth
(Only in case _ruby -v_ is *NOT* working)
56 1 Stephan Schuberth
<pre>which ruby  # TO CHECK WHERE IT SHOULD BE
57 1 Stephan Schuberth
whereis ruby  # TO CHECK WHERE IT IS INSTALLED</pre>
58 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).
59 1 Stephan Schuberth
60 6 Stephan Schuberth
h4. Fix via adding /usr/local/bin to $PATH
61 6 Stephan Schuberth
62 9 Stephan Schuberth
(Do this with your editor of choice, if you do not like nano.)
63 6 Stephan Schuberth
<pre>nano /etc/profile</pre>
64 6 Stephan Schuberth
65 6 Stephan Schuberth
Make the section with _pathmunge_ look alike like this:
66 6 Stephan Schuberth
<pre>#Path manupulation
67 6 Stephan Schuberth
if [ "$EUID" = "0" ]; then
68 6 Stephan Schuberth
    pathmunge /sbin
69 6 Stephan Schuberth
    pathmunge /usr/sbin
70 6 Stephan Schuberth
    pathmunge /usr/local/sbin
71 6 Stephan Schuberth
    pathmunge /usr/local/bin  # ADDED THIS
72 6 Stephan Schuberth
else
73 6 Stephan Schuberth
    pathmunge /usr/local/bin after  # ADDED THIS
74 6 Stephan Schuberth
    pathmunge /usr/local/sbin after
75 6 Stephan Schuberth
    pathmunge /usr/sbin after
76 6 Stephan Schuberth
    pathmunge /sbin
77 6 Stephan Schuberth
fi</pre>
78 6 Stephan Schuberth
79 6 Stephan Schuberth
OR ADD THIS AT THE END OF THE FILE:
80 6 Stephan Schuberth
81 6 Stephan Schuberth
<pre>nano /etc/profile
82 6 Stephan Schuberth
export PATH="$PATH:/usr/local/bin"</pre>
83 6 Stephan Schuberth
84 15 Stephan Schuberth
This sets the PATH for all Users beside root. For this setup you want to change the PATH for root, too:
85 6 Stephan Schuberth
86 6 Stephan Schuberth
<pre>nano ~/.bashrc
87 1 Stephan Schuberth
export PATH="$PATH:/usr/local/bin"</pre>
88 15 Stephan Schuberth
89 15 Stephan Schuberth
Logout your user and login again, to make the changes work.
90 6 Stephan Schuberth
91 6 Stephan Schuberth
h4. Fix via Symlink Creation 
92 6 Stephan Schuberth
93 7 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 creat symlinks for them, too.
94 6 Stephan Schuberth
Symlinks are created like this
95 6 Stephan Schuberth
96 1 Stephan Schuberth
<pre>ln -s /usr/local/bin/ruby /usr/bin/ruby</pre>
97 6 Stephan Schuberth
98 8 Stephan Schuberth
h4. Verify ruby to be working
99 6 Stephan Schuberth
100 16 Stephan Schuberth
<pre>which ruby  # MUST RETURN PATH TO RUBY
101 16 Stephan Schuberth
ruby -v  # MUST RETURN RUBY VERSION
102 1 Stephan Schuberth
cd ..</pre>
103 16 Stephan Schuberth
104 19 Stephan Schuberth
Now it has to work. When changing $PATH variable, did you log out and log on again with your current user?
105 18 Stephan Schuberth
If this does not function properly, other things later on will also not work.
106 1 Stephan Schuberth
107 1 Stephan Schuberth

246 1 Stephan Schuberth
247 12 Stephan Schuberth
h2. Set environment to "production" 
248 12 Stephan Schuberth
249 12 Stephan Schuberth
Rails has the concept of environments to represent the stages of an application’s lifecycle: test, development, and production by default. 
250 12 Stephan Schuberth
Specify your choice with the RAILS_ENV environment variable. 
251 12 Stephan Schuberth
Production has less verbose logging and is a bit faster, testing and development environment are not needed anyway for your Redmine.
252 12 Stephan Schuberth
253 12 Stephan Schuberth
Uncomment the following line in file redmine/config/environment.rb:
254 12 Stephan Schuberth
