  • %VOSNAV% ---+ Virtuoso Universal Server AMI for Amazon EC2 Instantiation Guide %TOC% ---++ Introduction The Virtuoso Universal Server AMI for Amazon EC2 comprises a cloud-based bundle of the following OpenLink and third-party products and services: * [[][Virtuoso Universal Server]] * [[VirtSponger][Virtuoso Sponger]] Middleware & Cartridges (extensible RDFizer covering 30+ different data formats) * [[][OpenLink Data Spaces (ODS)]] * [[][OpenLink Ajax Toolkit (OAT)]] * 3rd party PHP applications ([[][WordPress]], [[][MediaWiki]], [[][phpBB]], and [[][Drupal]]) ---++ Prerequisites 1 Register for an [[][Amazon Web Services]] (AWS) account. 1 New AWS accounts have been automatically signed up for the [[][Amazon S3 and EC2 Web Service]] for several years. If you created your AWS account a long time ago, you may now need to manually sign up for these services. ---++ Virtuoso AMI Setup & Instantiation Follow the steps below to set up and launch your Virtuoso EC2 AMI instance. 1 Subscribe to the [[][Virtuoso Universal Server (Cloud Edition) Amazon DevPay]] service to activate the Virtuoso AMI on your account. %BR%%BR%%BR%%BR% 1 After successful subscription the DevPay service redirects users back to this page to continue the AMI instantiation as detailed in step 4. %BR%%BR%%BR%%BR% 1 Important: Note that the activation key is only valid for 60 minutes, and is included as part of the redirect URL for AWS to use when instantiating the AMI. If you browser session is shut down for any reason, or if more than 60 minutes elapse before you take the next step, you will need to generate a new activation key, as follows -- 1 A new activation key can be generated through the Application Activation tab of the [[][Virtuoso Universal Server (Cloud Edition) AMI Application]] page. %BR%%BR%%BR%%BR% 1 Select Generate Key, followed by Go to Application, to get a new key. You will once again be redirected to this page (with the product code and new activation key passed in the URL), and can then continue the instantiation as detailed in step 4. %BR%%BR%%BR%%BR% 1 Open the [[][AWS Management Console]]. From here, you can see a dashboard showing any current instances you may have running and a menu of various areas to control (instances, AMIs, etc.). %BR%%BR%%BR%%BR% 1 You will need to create a new security group (firewall configuration) for the Virtuoso AMI. 1 Click on Security Groups at the bottom of the left menu. By default, there is one group called default visible. 1 Create a new security group (here called openlink) and, add the port 22/tcp (SSH) to enable ssh access to the AMI, also allow connections to port 80/tcp (HTTP) and port 8890/tcp (used by Virtuoso). Please refer to the Amazon EC2 [[][Authorizing Network Access to Your Instances]] document for further details. %BR%%BR%%BR%%BR% 1 Save it and return to the dashboard. 1 Now we need to create an instance of the image. 1 From the Console, select Launch Instances. 1 You need to choose an AMI. In the Community AMIs tab, type virtuoso to see the relevant images published by OpenLink — * Virtuoso Release 7 AMIs |*Edition*|*ID*|*Manifest file*| |64-bit |   ami-2c9de345   |   openlink/virtuoso-uim-unisvr-psnl/7.0/x86_64-centos-5.9.manifest.xml   | %BR% * Virtuoso Release 6 AMIs |*Edition*|*ID*|*Manifest file*| |64-bit |   ami-23d0334a   |   openlink/virtuoso-uim-unisvr-psnl/6.0/x86_64-centos-5.3.manifest.xml   | |32-bit |   ami-2fd03346   |   openlink/virtuoso-uim-unisvr-psnl/6.0/i386-centos-5.3.manifest.xml   | %BR% * Virtuoso Release 5 AMIs |*Edition*|*ID*|*Manifest file*| |64-bit |   ami-59628630   |   openlink/virtuoso-uim-unisvr-psnl/5.0/x86_64-fedora-linux-9.manifest.xml   | |32-bit |   ami-c46084ad   |   openlink/virtuoso-uim-unisvr-psnl/5.0/i686-fedora-linux-9.manifest.xml   | %BR% 1 Choose whichever image you prefer, 64-bit (x86_64) or 32-bit (i686) and press Select. %BR%%BR%%BR%%BR% 1 Enter the Number of Instances (normally 1). 1 Select the Instance Type. * Note: The Virtuoso Release 7 AMI is available in 64bit form only, thus an m1.large instance type or larger must be chosen. * Note: The optimal Instance Type will depend on the use for this instance, including the data to be hosted. If you intent to host your own [[VirtEC2AMIDBpediaInstall][DBpedia]], [[VirtEC2AMINeuroCommonsInstall][Neurocommons]], [[VirtEC2AMIBio2rdfInstall][Bio2RDF]] instance, see the instructions relevant to the data set before proceeding! 1 Choose a key-pair or create a new one for the purpose. This will be used as an SSH key to access your instance later. 1 Select the openlink security group created earlier. 1 Click the Launch button. %BR%%BR%%BR%%BR% 1 You will see a status page saying your instances are in the process of launching, and the next time you visit [[][the dashboard]] there will be an appropriate instance listed for you to simply Stop, Start, etc. %BR%%BR%%BR%%BR% ---++ Post-Installation Tasks ---+++ Update the OS and Virtuoso components on the AMI OpenLink Virtuoso Cloud Edition is based on Fedora and CentOS Core Linux images which you should update before first using your Virtuoso instance, and regularly thereafter. This can be done as follows: 1 Locate the key created above and run the command — chmod 600 MyKeyPair.pem 1 Connect to the EC2 AMI Server with the command — ssh -i MyKeyPair.pem root@your-ec2-instance-cname 1 The Virtuoso EC2 AMI installation is located in /opt/virtuoso. From this location first run the following commands to shutdown the Virtuoso server instance — . ./ oplmgr +stop 1 Important: Update the Virtuoso EC2 AMI installation to the latest OS and Virtuoso versions. Exact sequence depends on which Virtuoso Release you are running -- * Users of AMIs with Virtuoso Release 5 must run the following command sequence to first update the OpenLink License Manager (oplmgr) and license file (virtuoso.lic), and then update the OS and Virtuoso. DO NOT use this sequence with any other Virtuoso Release! yum update oplmgr virtuoso-ami-init yum update * Users of AMIs with Virtuoso Release 6 must run the following command sequence to first remove the pre-existing Virtuoso database file (virtuoso.db) and transaction log file (virtuoso.trx) , and then update the OS and Virtuoso. DO NOT use this sequence with any other Virtuoso Release! cd database rm virtuoso.db rm virtuoso.trx yum update * Users of AMIs with Virtuoso Release 7 or later should simply update the Virtuoso EC2 AMI installation to the latest OS and Virtuoso versions with the following command. DO NOT use this sequence with any earlier Virtuoso Release! yum update While you can, and should, keep the whole operating system up to date with this method, you can also upgrade only the Virtuoso components with the command — yum update --disablerepo=* --enablerepo=virtuoso ---+++ Adjust Virtuoso configuration files for your specifics 1 Edit the Virtuoso configuration file /opt/virtuoso/database/virtuoso.ini and set the DefaultHost parameter in the URIQA section to your-ec2-instance-cname (or whatever external cname the instance will be configured to use). This is required for the correct hostname to be picked up when using the ODS and other applications — [URIQA] DynamicLocal = 1 DefaultHost = your-ec2-instance-cname:80 1 Edit the Virtuoso configuration file /opt/virtuoso/database/virtuoso.ini and add the line Load8 = plain, qrcode to the [Plugins] section to enable qrcode support in the Virtuoso Server — [URIQA] [Plugins] LoadPath = ../hosting Load1 = plain, wikiv Load2 = plain, mediawiki Load3 = plain, creolewiki Load4 = plain, im Load5 = plain, wbxml2 Load6 = attach, Load7 = Hosting, Load8 = plain, qrcode ---+++ Start the License Manager and Virtuoso processes 1 The OpenLink License Manager can now be restarted with the command — /usr/sbin/oplmgr +start 1 The Virtuoso server can then be restarted with the command — ---+++ First-run task: Change default passwords Virtuoso has two system users, dba (for SQL/relational/system-admin tasks) and dav (for WebDAV and ODS), with default passwords matching their usernames. On any live server, it is essential to change these two passwords to something more secure, of your own choosing. To this end, 1 Open the location http://your-ec2-instance/conductor/ in a web browser. %BR%%BR%%BR%%BR% 1 Log in as dba/dba %BR%%BR%%BR%%BR% 1 Select System Admin from the menu and then User Accounts from the second level menu. %BR%%BR%%BR%%BR% 1 Click Edit beside the dba user. %BR%%BR%%BR%%BR% 1 Enter replacement passwords in both boxes and press the Save button at the bottom to return to the user-list. ---++ Update and start example A complete update and initial startup run will look something like this — $ chmod 600 MyKeyPair.pem $ ssh -i MyKeyPair.pem The authenticity of host ' (' can't be established. RSA key fingerprint is 58:ae:0b:e7:a6:d8:d0:00:4f:ca:22:53:42:d5:e5:22.
