Download

LATEST VERSION: GOCDBv5

• Install docs for V5 comming soon.
• A packaged V5 release will also be made available for download soon.
• In the meantime, early adopters can check out the v5 src from svn:

svn checkout https://www.sysadmin.hep.ac.uk/svn/grid-monitoring/branches/gocdb/Doctrine%20Web%20Portal 

Note, if you are asked to authenticate with a client certificate as below, you can dismiss by pressing Enter

Authentication realm: https://www.sysadmin.hep.ac.uk:443
Client certificate filename: <ENTER to dismiss>

OLD v4.4 Install doc has been relocated

Deployment

System prerequisites

GOCDB-5 regional module has two components: a database and a web front end. Both components can work on the same machine but it is very likely that in most environments they will be separated. This is what we would advise anyway. Machine requirements for these 2 components are described below.

Database

• Mysql/Oracle/Sqlite

Web frontend

The machine to use as the web frontend will need the following:

• Apache http server version 2.2 or higher.
• PHP version 5.3 or higher (version <=5.2 has some OOP related bugs).
  • PHP oci8 extension
    
• a X509 host certificate for the machine

Optional

• PHP Unit for testing developments

Preparing your installation

Database preparation

For Dave :)

GOCDB file system

Place the GocDB source folder on your chosen web server.

PEAR

Pear is recommended to install Doctrine and PHPUnit, many builds of PHP come pre-bundled with PEAR. 

http://pear.php.net/manual/en/installation.getting.php

Verify the PEAR installation by running pear version on the command line.

$ pear version
PEAR Version: 1.9.4
PHP Version: 5.3.8
Zend Engine Version: 2.3.0
Running on: Windows NT ESCPC0095 6.1 build 7601 (Windows 7 Business Edition Service Pack 1) i586

Doctrine

Doctrine can be installed using PEAR. First add the Doctrine and Symfony channels to PEAR:

$pear channel-discover pear.doctrine-project.org
$pear channel-discover pear.symfony.com

Then install Doctrine and it's dependencies:

$pear install --alldeps doctrine/DoctrineORM

Verify the Doctrine installation by running "doctrine --version" on the command line:

$ doctrine --version
Doctrine Command Line Interface version 2.3.3

See the possible errors and troubleshooting section if you encounter errors at this point.

Apache

/////

PHPUnit

PHPUnit is an optional choice for GOCDB users. GOCDB5 includes a test suite of unit tests that can be used to verify buisness logic and database connections for a deployed instance of GOCDB. In addition developers extending and modifying GOCDB can write unit tests for their own developements. To install PHPUnit use PEAR:

$pear clear-cache
$pear config-set auto_discover 1
$pear install pear.phpunit.de/PHPUnit

This install can then be verified using "phpunit --version" on the command line:

$ phpunit --version
PHPUnit 3.7.27 by Sebastian Bergmann.

Deploying GOCDB5

Configuration of the database connection

You should now have all the required blocks in place to deploy GOCDB V5. To Deploy the database schema to your desired database using Doctrine navigate to to gocDBSrc/lib/Doctrine/Deploy folder. In this folder you will configure the database connection details for your database. Depending on the type of database you are using open the bootstrap_doctrine.php file your database:

bootstrap_doctrine.php.mysql  -> For MySQL databases
bootstrap_doctrine.php.oci    -> For Oracle databases
bootstrap_doctrine.php.sqlite -> For SQLite databases

In the bootstrap_doctrine file complete the connection details for your database.

For Oracle:

$conn = array(
        'driver' => 'oci8',
        'user' => 'doctrine',
	'password' => 'doc',
	'host' => 'localhost',
	'port' => 1521,
	'dbname' => 'XE'
);

For MySQL:

$conn = array(
    'driver' => 'pdo_mysql',
    'user' => 'Doctrine',
	'password' => 'doc',
	'host' => '127.0.0.1',
	'dbname' => 'doctrine'
);

For SQLite:

$conn = array(
    'driver' => 'pdo_sqlite',
    'path' => __DIR__ . '/db.sqlite',
);

Note: Doctrine can use APC caching however this is not suitable for all deployments. To disable comment out the APC configuration lines within the bootstrap_doctrine.php file:

$config->setMetadataCacheImpl(new \Doctrine\Common\Cache\ApcCache());
$config->setQueryCacheImpl(new \Doctrine\Common\Cache\ApcCache());

Deploying GOCDB

To deploy GOCDB execute the deploy file for your database found in the deploy folder.

gocDBSrc/lib/Doctrine/deploy/oracleDeploy.sh
gocDBSrc/lib/Doctrine/deploy/mysqlDeploy.sh
gocDBSrc/lib/Doctrine/deploy/sqlite.sh

Within the source code you will also find a set of sample data to deploy with GOCDB. To deploy this data specify the location of the sample data folder when deploying:

$./oracleDeploy.sh sampleData/

This will begin the process of deploying the database scheme and data if provided to your database.

Apache Configuration

httpd.conf

Now that your database is deployed the final step is to configure Apache.

A few modules need to be enabled for GOCDB to work, check these are enabled on your Apache and if not enable them. 

In httpd.conf enable ssl_module by un-commenting these lines:

LoadModule ssl_module modules/mod_ssl.so

and

extension=php_openssl.dll

Depending on the database you are using the supporting module may also need to be enabled. For example Oracle requires the oracle module to be uncommented:

extension=php_oci8_11g.dll

Take the file gocdbssl.conf and place this file in the apache/conf/extra folder. In httpd.conf include the gocdbssl.con by adding the following line under the heading Supplemental Configuration:

Include conf/extra/gocdbssl.conf

gocdbssl.conf

This file defines the location of resources required by GocDB.

Paths

The first step is to setup the paths for the DocumentRoot, ErrorLog and TransferLog and define the ServerName and ServerAdmin details for your particular web service where you are hosting GocDB.

SSL Keys

The SSLCertificateFile should point to the location of your server SSL key file. The SSLCertificateKeyFile -- The SSLCACertificationPath should point to the location of your CA certificates which can be obtained from: //Ask Dave

For development the SSLCertificatedFile and SSLCertificateKeyFile can be self signed certificates. However these must not be used in production.

Aliases

The final step is to set the Alias to map your desired directory for GocDB webportal and Programmatic Interface (PI) to the correct folder and ensure the correct rules are defined for your server.

For the webportal the following settings are an example:

    Alias "/GocDBWebPortal" "\gocDBsrc\htdocs\web_portal"
    <Directory "\gocDBsrc\htdocs\web_portal">
            SSLVerifyClient  require
            Options FollowSymLinks Indexes
            Order deny,allow
            Allow from 127.0.0.1
            deny from all  
        </Directory>

The alias should and file location should also be set for the public PI and private PI. Public PI:

Alias "/doc/public" "\gocDBsrc\htdocs\PI\public"
<Directory "\gocDBsrc\htdocs\PI\public">

Private PI:

Alias "/doc/private" "\gocDBsrc\htdocs\PI\private"
<Directory "\gocDBsrc\htdocs\PI\private">

First Use

You should now be able to navigate to the GocDB webportal on your host using the URL defined in your alias. You will need to install a browser certificate that is suitable for the SSL keys you defined for your host to be able to view GocDB.
