</code>
==== Install Tomcat and Solr ====
  1. Verify that java is installed
<code>
java
</code>
  2. Add tomcat User and Unpack tomcat
 <code>

To make things easier, we have copied the already configured copy on Tomcat and Solr on server;

Just Untar the following file to /opt directory;
ftp://qacollab01.exphosted.com/softrepo/tincan/opt_combo.tgz 


 Obsolete method if the above step does not work;
 
 mkdir /opt/tomcat7
 useradd tomcat
 usermod -m -d /opt/tomcat7 tomcat
  
 cd /opt/tomcat
wget --user=expbbbu --password=<RETRACTED> ftp://qacollab01.exphosted.com/softrepo/tincan/installed-software/apache-tomcat-7.0.54.tar.gz | tar xz
 chown -R tomcat:tomcat /opt/tomcat7

</code>
Init script.
<code>
#!/bin/bash
# description: Tomcat Start Stop Restart
# processname: tomcat
# chkconfig: 234 20 80
#JAVA_HOME=/usr/java/jdk1.7.0_05
#export JAVA_HOME
#PATH=$JAVA_HOME/bin:$PATH
export PATH
CATALINA_HOME=/opt/tomcat7/bin

case $1 in
start)
/bin/su tomcat $CATALINA_HOME/startup.sh
;;
stop)
/bin/su tomcat $CATALINA_HOME/shutdown.sh
;;
restart)
/bin/su tomcat $CATALINA_HOME/shutdown.sh
/bin/su tomcat $CATALINA_HOME/startup.sh
;;
status)
test "$(ps -ef|grep java|grep -i catalina 2>1)" && echo "Tomcat-Solr is running" || echo -e "\e[31m\e[0mTomcat-Solr is not running"
;;
esac
exit 0
</code>
<code>
 chmod +x /etc/init.d/tomcat7
 chmod 755 /etc/init.d/tomcat7
 chkconfig --add tomcat7
 chkconfig tomcat on
 </code>
  3. Unpack solr 
<code>
mkdir /opt/solr && cd /opt/solr
wget --user=expbbbu --password=<RETRACTED> ftp://qacollab01.exphosted.com/softrepo/tincan/installed-software/solr-4.8.1.zip
unzip solr-4.8.1.zip
cp -r solr/example/lib/ /opt/tomcat/lib/
chown -r tomcat:tomcat /opt/solr

  4. Configure Solr 
  - Data Dir:
<code>
nano /opt/solr/example/solr/conf/solrconfig.xml
</code>
Create a shared data or a local data drive and set the path here. \\
Also, copy Learnexa schema.xml.

  - Configure Tomcat.
<code>
# for multicore
cd /opt/tomcat7
mkdir -p Catalina/localhost
nano solr.xml
</code>
Then add:
<code>
<Context docBase="/opt/solr/example/solr/webapp/solr.war" debug="0" crossContext="true">
  <Environment name="solr/home" type="java.lang.String" value="/opt/solr/example/solr" override="true" />
</Context>
</code>

==== Application Runtime Dependencies ====
=== Create application user ===
<code>
/usr/sbin/adduser "expdev01"
#set regular password
</code>
=== Log out as root and login as application user created above ===
=== Install RVM ===
  1. Ensure:
<code>
whoami
#expdev01
</code>

  vi ~/.profile

  export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

  [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" 
  
  vi ~/.bashrc
  
  export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
  [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"  

  2. Install RVM
<code>
\curl -sSL https://get.rvm.io | bash
</code>
  
  3. Install and use Ruby 2.1.5

     rvmsudo rvm install 2.1.5
     rvmsudo rvm use 2.1.5
     sudo gem update --system 2.4.5

 
 4. Verify
<code>
which ruby
#/home/expdev01/.rvm/rubies/ruby-2.1.5/bin/ruby
</code>
=== Setup Bundler and Gems ====
<code>
gem install rails -v '4.2.6'
gem install bundler -v '1.11.2'
gem install eventmachine -v '1.0.7'
gem install mysql2 -v '0.3.18'
gem install nokogiri -v '1.6.6.2'
gem install rake -v '10.4.1'
gem install rack -v '1.6.0'
gem install passenger -v '4.0.44'
gem install capistrano-bundler -v '1.1.4'
gem install capistrano-ext -v '1.2.1'
gem install capistrano-log_with_awesome -v '0.0.2'
gem install capistrano-passenger -v '0.0.2'
gem install capistrano-rails -v '1.1.1'
gem install capistrano-rvm -v '0.1.1'


</code>








=== Setup Nginx ===
<code>
rvmsudo passenger-install-nginx-module


</code>





====  Deploy Application ====

Following are the steps to be followed. Please note that "development" needs to be replaced with "staging"/"production" based on the environment you are setting up.
   
<code>
   download file from 107.170.68.123:/soft/deploy-bk.tar.gz
   unzip deploy-bk.tar.gz 
   mv deploy-bk /deploy
   
   chown -R expdev01:expdev01 /deploy
   
   download file from 107.170.68.123:/soft/nginx.conf
   
   Replace the file  /opt/nginx/conf/nginx.conf
   
   cd /home/expdev01
   mkdir tincan
   cd tincan
   bundle exec cap install
   
   mv tincan tincan-old
   
   download file from 107.170.68.123:/soft/home-bkup.tar.gz
   
   tar xvf home-bkup.tar.gz
   
   download file from 107.170.68.123:/soft/capistrano.zip

   cd /home/expdev01/tincan/lib/
   unzip capistrano.zip

   download file from 107.170.68.123:/soft/bin.zip
   cd /home/expdev01/
   unzip bin.zip

   
   chown -R expdev01:expdev01 /home/expdev01
   
</code>
   
   
=== Configure the app and DB ===
   
   cd /deploy/tincan/current/
   
   # Specify the flavor of the app in config/environments/development.rb 
   DEFAULT_FLAVOR = "expertusone" #(Or "learnexa" depending on for whom you are setting up.)
   
   #update databased details in config/database.yml development stanza. 
   #Specify makara gem configs, if you are adding a slave db.
   
   #run the below - 
   bundle install
   bundle exec rake db:create RAILS_ENV=development
   bundle exec rake db:migrate RAILS_ENV=development
   bundle exec rake db:seed RAILS_ENV=development


   vi config/environments/development.rb

   APP_URL     = "http://devlrs01.learnexa.com"
   API_URL     = "http://devlrs01.learnexa.com"
   
   Note make sure added /etc/hosts entry if not have public dns
   
   Restart apache.
   
   
   
   
 
=== Deploy scripts changes ===

Download file from 107.170.68.123:/home/expdev01/tincan/runcap.sh

Change the tincan directory files as needed with environment and db values.
   
sh /home/expdev01/tincan/runcap.sh
