Phase 1: Setup Redmine
Step 1
Install required packages.
Step 2
Check out Redmine trunk.
$ sudo svn co http://redmine.rubyforge.org/svn/trunk redmine
Step 3
Install required ruby gems:
Note 1: We may need to update Rails RAILS_GEM_VERSION in file [redmine]/config/environment.rb to reflect actual version of Rails gems installed.
Note 2: We may need to create soft link for rails & mongrel executables for convenient
$ sudo ln -s /var/lib/gems/1.8/bin/rails /usr/local/bin/
$ sudo ln -s /var/lib/gems/1.8/bin/mongrel_cluster_ctl /usr/local/bin/
Step 4
Create mysql database
# Enter mysql root password when prompted
Run the following code in mysql, substitute your own database name, password, …
CREATE user 'redmine'@'localhost' IDENTIFIED BY 'my_password';
GRANT ALL privileges ON redmine.* TO 'redmine'@'localhost';
Step 5
Create/Update database parameters in [redmine]/config/database.yml accordingly to prior step info.
adapter: mysql
database: redmine
host: localhost
username: redmine
password: my_password
encoding: utf8
Step 6
Initialize the database
$ sudo rake config/initializers/session_store.rb
# Load db schema
$ sudo rake db:migrate RAILS_ENV="production"
$ sudo rake redmine:load_default_data RAILS_ENV="production"
Step 7
Create redmine user & setting up directory permission
$ sudo useradd redmine
$ sudo mkdir tmp public/plugin_assets
$ sudo chown -R redmine:redmine files log tmp
$ sudo chmod -R 755 files log tmp public
Step 8
Testing the application server
The server is listening on [http://localhost:3000].
Phase 2: Setup Apache & Mongrel Cluster
Step 1
Create mongrel cluster configuration files for Redmine.
# Test mongrel_installation
$ sudo mongrel_rails cluster::start
Step 2
Create apache virtual host file at /etc/apache/sites-available/
ServerName your.virtual-host.com
DocumentRoot /srv/redmine
<Directory /srv/redmine/public>
AllowOverride FileInfo Indexes
</Directory>
RewriteEngine On
# Redirect all non-static requests to Mongrel
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ balancer://redmine_cluster%{REQUEST_URI} [P,QSA,L]
ProxyPassReverse / balancer://redmine_cluster
ProxyPreserveHost on
<Proxy balancer://redmine_cluster>
BalancerMember http://localhost:3000
BalancerMember http://localhost:3001
BalancerMember http://localhost:3002
</Proxy>
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
# Block access to .svn directories
<DirectoryMatch "^/.*/\.svn/">
ErrorDocument 403 /404.html
Order allow,deny
Deny from all
Satisfy All
</DirectoryMatch>
</VirtualHost>
Step 3
Turn on the virtual host and required modules
$ sudo a2enmod proxy_http
$ sudo a2enmod proxy_balancer
$ sudo a2ensite <your-virtualhost-file>
# Restart web server
$ sudo /etc/init.d/apache2 restart
Phase 3: Surviving the reboot & G!Mail SMTP
Step 1
Create global mongrel_cluster configuration
$ cd /etc/mongrel_cluster
$ sudo ln -s /srv/redmine/config/mongrel_cluster.yml /etc/mongrel_cluster/redmine.yml
Step 2
Update the services
$ sudo cp /var/lib/gems/1.8/gems/mongrel_cluster-1.0.5/resources/mongrel_cluster /etc/init.d/
$ sudo chmod +x /etc/init.d/mongrel_cluster
$ sudo /usr/sbin/update-rc.d -f mongrel_cluster defaults
Step 3
Configure G!Mail
production:
delivery_method: :smtp
smtp_settings:
tls: true
address: "smtp.gmail.com"
port: '587'
domain: "smtp.gmail.com"
authentication: :plain
user_name: "your_email@gmail.com"

How to hide files in Nautilus
Author: lexhung16 Sep
In Linux, files which name start by a dot ‘.’ are hidden by default in most file managers. However, there are cases when we want to hide dot-file from our view. For examples:

Note: This trick only works in Nautilus. It won’t work in Konqueror or Dolphin. I don’t know if it works in other file managers or not.

The GNOME-Colors is a project that aims to make the GNOME desktop as elegant, consistent and colorful as possible.
The current goal is to allow full color customization of themes, icons, GDM logins and splash screens. There are already five full color-schemes available; Brave (Blue), Human (Orange), Wine (Red), Noble (Purple) and Wise (Green).
GNOME-Colors is mostly inspired/based on Tango, GNOME, Elementary, Tango-Generator and many other open-source projects.
