#Install steps

##Setting Up Laravel

mkdir gitrepo

yum install php php-mcrypt php-pdo httpd mysql mysql-server php-mysqlnd php-xmlrpc

service mysqld start; chkconfig mysqld on

cd /usr/local/bin; curl -sS https://getcomposer.org/installer | php; mv composer.phar composer; 

cd ~/gitrepo

composer create-project laravel/laravel --prefer-dist

##Staging scripts Production:

• deploy.sh:

#!/bin/bash
rm -Rf p4
git clone [email protected]:wbirkmaier/p4.git
cd p4
composer install --prefer-dist
chmod -R 777 app/storage
cd ..

• stage.sh

#!/bin/bash
rm -Rf laravel
cp -R /home/wbirkmaier/gitrepo/test/laravel/ .
cd laravel
chmod -R 777 app/storage

##Sync to apache dir

• cp <project> in /var/www/html
• replace DocumentRoot "/var/www/html" in vi /etc/httpd/conf/httpd.conf in <project>/public

<Directory "/var/www/html">
    AllowOverride All

• make sure you

chmod -R 777 app/storage

• allow httpd with selinux

setsebool -P httpd_unified 1

##Debug environments

/app/config/local/app.php We set debug to true
/app/config/production/app.php We set debug to false
/app/config/app.php We set debug to false

##Determine Environment vi /bootstrap/start.php

• For all environments to get devel environment

$env = $app->detectEnvironment(array(

    'local' => array('*'),

));

• Otherwise do this for each environment:

$env = $app->detectEnvironment(array(

    'local' => array('Jane-Doe-MacBook-Air.local'),
    'production' => array('ex-std-node292.prod.rhcloud.com'),

));

##Database Setup mysql -u root

create database wilxc;

exit the database.

/usr/bin/mysql_secure_installation and say yes to all, set password

Then edit the files below:
vi /app/config/database.php
vi /app/config/local/database.php

 'mysql' => array(
                        'driver'    => 'mysql',
                        'host'      => 'localhost',
                        'database'  => 'laravel',
                        'username'  => 'root',
                        'password'  => '',

##Test Database vi app/routes.php

Route::get('test', function()
{
    echo 'Environment: '.App::environment().'<br>';
    $results = DB::select('SHOW DATABASES;');
    echo print_r($results);
    phpinfo();
}); 

##Migration (Schemas)

php artisan migrate:make create_test_table

• Run the migration

php artisan migrate

##Set up Andy Goodwin Code for laravel In app/models add XenApi.php, case matters

#User Authentication app/config/session.php

#Credits & External notes

• PHP XenApi code from https://github.com/andygoodwin/PHP-xenapi
• XenServer Managment API http://docs.vmd.citrix.com/XenServer/6.2.0/1.0/en_gb/api/
• Bootstrap http://getbootstrap.com/
• Font Awesome https://fortawesome.github.io/Font-Awesome/

##Tips and Trick

• php --ini
• phpinfo();
• php code.php

   "get_by_name_label"
   "get_by_uuid"
   "get_record"
   "get_all"
      
   Also you can do VM_get{fields}, VM_get_is_a_template, or VM_get_bios_strings
   set_X: change the value of field X (only if it is read-write);
   get_X: retrieve the value of field X;
   add_to_X: add a key/value pair (only if field has type set or map); and
   remove_from_X: remove a key (only if a field has type set or map).
   http://docs.vmd.citrix.com/XenServer/6.2.0/1.0/en_gb/api/
   
   Enums are operations you can do directly against an OpaqueRef
   Credentials::loginXen()->VM_clean_shutdown($vmRef);

#Example of drilling through the arrays

<?php $poolGetAll = $xenserver->pool_get_all(); ?>
<?php echo '<pre>'; print_r($poolGetAll); echo '</pre>'; ?>
<?php $poolObjRef = $poolGetAll["0"]; ?>
<?php echo '<pre>'; print_r($poolObjRef); echo '</pre>'; ?>        
<?php $poolNameLabel = $xenserver->pool_get_record($poolObjRef); ?>
<?php echo '<pre>'; print_r($poolNameLabel); echo '</pre>'; ?>
