Redmine installation guide (Ubuntu)
Author: lexhung23 Dec
Following is a guid to install Redmine (svn trunk) on Ubuntu 9.10.
The assumed location of Redmine is /srv/redmine
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"
password: "your_password"

You can, but it’s no fun.
Automatic virtual host with Apache
Author: lexhung16 Oct
When developing with CakePHP, we can setup Apache to automatically redirect a domain to a specific CakePHP application.
We can set computer’s aliases using hosts file. Apache will automatically map aliases to different DocumentRoot:
app1.mybox.com -> /var/www/cakephp/app1.mybox.com/webroot
app2.somewhere.com -> /var/www/cakephp/app2.somewhere.com/webroot
Step 1: Enable the mod_vhost_alias:
Step 2: Replace the DocumentRoot statement in default virtualhost configuration file with two lines:
VirtualDocumentRoot /var/www/cakephp/%0/webroot
(If you use a different virtualhost, make sure that you’re editing the right configuration file)
Step 3: However, the mod_rewrite doesn’t play nice with mod_vhost_alias. We need to edit the .htaccess file in {APP}/webroot folder.
RewriteBase / # << Add this line
RewriteCond %{REQUEST_FILENAME} !-d
Step 4: Restart Apache.
Below is my default virtual host configuration for your reference:
ServerAdmin webmaster@localhost
UseCanonicalName Off
VirtualDocumentRoot /var/www/cakephp/%0/webroot
<Directory />
Options FollowSymLinks
AllowOverride All
</Directory>
ErrorLog /var/log/apache2/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog /var/log/apache2/access.log combined
</VirtualHost>
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:
- Desktop folder in our home folder.
- Dropbox
- lost+found directory at the partition root
- …
In Nautilus (default GNOME file manager) there’s a way. Add a file named
with each line is the name of the file/folder you want to hide.
For example, if you want to hide Desktop from home folder you may type this command in the terminal:
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.
