sudo gem install passenger

If you want run the passenger behind apache then install passenger module for apache

export PATH=/opt/apache2/bin:$PATH (required to put apxs in path; set the apxs path as per your apache installation)
sudo passenger-install-apache2-module

#Add following in httpd.conf (the passenger PATH will vary depending on version installed, change LoadModule and PassengerRoot accordingly)

LoadModule passenger_module /usr/local/lib/ruby/gems/1.8/gems/passenger-3.0.0/ext/apache2/mod_passenger.so
PassengerRoot /usr/local/lib/ruby/gems/1.8/gems/passenger-3.0.0
PassengerRuby /usr/local/bin/ruby

For development purpose a standalone version of Passenger should suffice

cd /path/to/your/webapp
passenger start

[Note: This step is not required on the development machine]

wget http://rubyforge.org/frs/download.php/59598/cruisecontrol-1.4.0.tgz
tar -xzvf cruisecontrol-1.4.0.tgz

copy the cruisecontrol folder over to the /opt/apache2/htdocs/cruisecontrol and add following virtual host entry in the httpd.conf file

<VirtualHost 184.106.207.71:80>
  ServerName tracker.exphosted.com:80
  ErrorLog "logs/cruisecontrol-error.log"
  CustomLog "logs/cruisecontrol-access-log" common
  DocumentRoot /opt/apache2/htdocs/cruisecontrol/public
  <Directory /opt/apache2/htdocs/cruisecontrol/public>
    AllowOverride all
    Options -MultiViews
  </Directory>
  RailsDefaultUser root
</VirtualHost>

Restart the apache

sudo /opt/apache2/bin/httpd -k restart

The cruisecontrol dashboard should now be available at http://tracker.exphosted.com

Now add the crossbow/trunk to the cruisecontrol

cd /opt/apache2/htdocs/cruisecontrol
sudo ./cruise add crossbow-trunk -u file:///svnroot/crossbow/trunk

ImageMagick is used by RMagick gem. The application uses RMagick to process the images.

sudo yum install ImageMagick
sudo yum install ImageMagick-devel

Memcached is required as it will be used as the cache store for the rails application. Before installing memcached install the dependency required for it. Follow the below mentioned steps

sudo yum install libevent-devel

wget http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz
tar -zxvf memcached-1.4.5.tar.gz
cd memcached-1.4.5
./configure
make
make test
sudo make install
memcached    (or, memcached -d -P pidfile -l 127.0.0.1)

Once the memcached is installed and running we need to put some startup scripts to make sure that memcached server starts when the machine boots.

sudo touch /etc/memcached.conf

And put in:

#Memory
-m 16
# default port
-p 11211
# user to run daemon nobody/apache/www-data
-u nobody
# only listen locally
-l 127.0.0.1

sudo touch /etc/init.d/memcached
sudo chmod +x /etc/init.d/memcached

And put in

ffmpeg is used to convert media files to flv format.

First of all, edit /etc/yum.repos.d/CentOS-Base.repo and add those lines at bottom of file:

[dag]
name=Dag RPM Repository for Centos
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
enabled=1

Install ffmpeg

sudo yum install ffmpeg ffmpeg-devel

If you get an error “Public key for faac-1.26-1.el5.rf.x86_64.rpm is not installed” then execute following command

sudo rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Alternatively, you can import the GPG key for dag into rpm, and re-run "yum install ffmpeg ffmpeg-devel"

The key is at: http://apt.sw.be/RPM-GPG-KEY.dag.txt

Same has been shown below (copy the text below, including the BEGIN and END lines) to a file (eg: /etc/pki/rpm-gpg/RPM-GPG-KEY.dag and import into rpm with
"rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY.dag" command)

Install again

sudo yum install ffmpeg ffmpeg-devel

Post installation Check :

1. Please make sure that your ffmpeg version is the latest and it has libx264 and AAC support enabled.

The latest version till date is 0.8.10 If you are on Fedora or redhat the latest version you will get the latest version by default when you use yum command

To Check your configuration just type ffmpeg -i .

You should see something like this

ffmpeg -i

ffmpeg: missing argument for option 'i'

It should have -enable-libx264. (AAC seems to by default always)

2. Once you have checked out the code, make sure that ffmpeg has a required preset for libx264. Get the preset from <CROSSBOW_RAILS_DIR>/config/ffmpeg and copy this file to your –datadir from the above ffmpeg command out put (generally /usr/share/ffmpeg).

To upgrade the existing version or install from scratch, down the following rpms, packages and install in the given order

Mandatory (download and install) whether installing ffmpeg as rpm or from source code

Post installation check

1. Please make sure that your ffmpeg version is the latest and it has libx264, libfaac and AAC support enabled.

It should have -enable-libx264 and -enable-libfaac. (AAC seems to by default always)

2. Once you have checked out the code, make sure that ffmpeg has a required preset for libx264. Get the preset from <CROSSBOW_RAILS_DIR>/config/ffmpeg and copy this file to your –datadir from the above ffmpeg command out put (generally /usr/share/ffmpeg).

For installation on Ubuntu follow the steps given @ https://www.vimp.com/en/web/faq-installation/items/how-to-compile-ffmpeg-for-ubuntu-and-debian.html

Chat Installation and Configuration Steps

File Upload Indicator Installation and Configuration

NOTE: Edit file /home/expdevl/bin/solr_sss.sh to comment/uncomment following lines to reflect appropriate environments:

### Comment or Uncomment the rake environments as requied ###
#        rake sunspot:solr:start RAILS_ENV=staging
       rake sunspot:solr:start RAILS_ENV=development
       rake sunspot:solr:start RAILS_ENV=test

END NOTE:

Manage as expdevl user:

cd /home/expdevl/bin
./solr_sss.sh stop (to stop solr process/es)
./solr_sss.sh start (to start solr process/es)
./solr_sss.sh status (to check status of running solr process/es)

Manage as root:

service stop solr
service start solr
service status solr

Manage as expdevl user:

cd /home/expdevl/bin
./redis_node_sss.sh stop
./redis_node_sss.sh start
./redis_node_sss.sh status

Manage as root:

service redis_nod stop
service redis_nod start
service redis_nod status

Manage as root:

service httpd stop
service httpd start
service httpd status

NOTE: If running as expdevl user, prefix the above with sudo /sbin/ (so end command would look like “sudo /sbin/service httpd status”)

The svn server and soffice (headless) are started as part of system startup (along with the above processes). In case you need to restart (or start) if its not running, run the below as root or sudo:

svnserver

pkill -15 svnserve
/usr/bin/svnserve -d

soffice

pkill -15 soffice.bin
at now <<EOF
/usr/lib64/openoffice.org3/program/soffice.bin -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard
EOF

Add a Virtual hosts entry in the apache config file (httpd.conf) which looks similar to this

<VirtualHost 184.106.207.71:80>
  ServerName stage01.exphosted.com:80
  ServerAlias *.stage01.exphosted.com
  ErrorLog "logs/crossbow-error.log"
  CustomLog "logs/crossbow-access-log" common
  DocumentRoot /deploy/crossbow/current/public
  <Directory /deploy/crossbow/current/public>
    AllowOverride all
    Options -MultiViews
  </Directory>
  RailsEnv development
  RailsDefaultUser root
</VirtualHost>

To enable the application for https add another VirtualHost entry

<VirtualHost 184.106.207.71:443>
  ServerName stage01.exphosted.com
  ServerAlias *.stage01.exphosted.com
  ErrorLog "logs/crossbow-error.log"
  CustomLog "logs/crossbow-access-log" common
  DocumentRoot /deploy/crossbow/current/public
  <Directory /deploy/crossbow/current/public>
    AllowOverride all
    Options -MultiViews
  </Directory>
  RailsEnv development
  RailsDefaultUser root
  SSLEngine on
  SSLCertificateFile /etc/apache2/conf/server.crt
  SSLCertificateKeyFile /etc/apache2/conf/server.key

  SetEnvIf User-Aget ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
</VirtualHost>

• The DocumentRoot should point to the public folder of the rails application.
• ServerAlias is required so that requests for subdomains of stage01.exphosted.com is routed to this virtual host. e.g. xxx.stage01.exphosted.com should be processed.
• SSLCertificateFile should point to the certificate file that was created
• SSLCertificateKeyFile should point to the key file.

To create a self-signed certificate use the following command

openssl req -new -newkey rsa:2048 -days 365 -nodes -x509 -keyout server.key -out server.crt

This command generates 2 files, server.key and server.crt

For the application to work based on different subdomains, one needs to ensure that the DNS entries for these wildcard sub-domains points to the server where we have hosted the application. At present, it is on stage01.exphosted.com ( IP - 184.106.207.71). We should ensure that xyz.stage01.exphosted.com also resolves to the same IP address. (xyz - can be any subdomain). We need to make dns changes to ensure that *.stage01.exphosted.com points to 184.106.207.71

The Application uses bundler gem to manage the gem dependencies. Install the bundler gem first.

sudo gem install bundler

If you are on OSX, you will need to do the following to install the mysql gem

sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

Once the bundler gem is installed, from the application directory (eg: /deploy/crossbow/current), run

bundle install

This would install all the necessary gems required by the application.

If the rmagick gem fails, with an error: Installing rmagick (1.15.17) with native extensions /usr/local/lib/ruby/site_ruby/1.8/rubygems/installer.rb:483:in `build_extensions': ERROR: Failed to build gem native extension.

yum install rpm-build cabextract
wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec
rpmbuild -ba msttcorefonts-2.0-1.spec
rpm -ivh /usr/src/redhat/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm
cd /usr/share/fonts/default/
ln -s ../msttcorefonts TrueType

If the sunspot_rails gem give a dependency error then install them using

$ sudo apt-get install libxslt-dev libxml2-dev   (on ubuntu)

sunspot-rails uses nokogiri gem. In case of any other issues when install the sunspot-rails gem refer to http://nokogiri.org/tutorials/installing_nokogiri.html

bundle install will end with this message:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Modify the database.yml file to reflect proper DB settings in development and test section and then run following rake task to create all the databases.

rake db:create:all

Once the DBs are created run the migrations to create necessary tables using following command.

rake db:migrate
rake db:migrate RAILS_ENV=test

Run the solr server in test environment

rake sunspot:solr:start RAILS_ENV=test

Run all the tests to make sure that the setup is done correctly

rake test

Run the rake db:seed to create the default company (This is just one time task)

rake db:seed

The default company will be created with name 'default' and subdomain as 'default'. No subdomain in url will refer to default company. e.g. http://localhost:3000 will take default company as a context. An admin user for the default company will also be created. The username for admin user is 'expertus_admin' and password is 'password'.

- Click on “Create Company” tab option and enter the details for the company and email subdomains for the company

- The value of 'subdomain' field will have to be used in the url when access/refering to this company. e.g. if value of subdomain field is 'xxx' then http://xxx.demo.localhost.com:3000 will be the base url for the company.

- To run the application locally with the given subdomain you need to modify the /etc/hosts file to point xxx.localhost to loopback IP address 127.0.0.1. i.e. the hosts file should have following entry if companies with subdomain 'xxx' and 'yyy' is created. Note that the default.demo.localhost.com is for the default company.

127.0.0.1       demo.localhost.com default.demo.localhost.com airtelinc.demo.localhost.com
