3 CycleServer Grid Engine Guide Administration Requirements Before proceeding with the installation, please make sure the following prerequisites are met: A 32-bit or 64-bit Linux distribution. At least 8GB RAM. 2 or more cores. At least 50GB free disk space. Administrator (root) privileges. Open Grid Scheduler (OGS) or Sun Grid Engine (SGE) 6.2u6 or higher. Ganglia with a running gmetad daemon, monitoring all nodes in the cluster. Recommended: Chef client running on all nodes in the cluster. The scheduler host must be accessible via passwordless (key-based) SSH from the machine that is running CycleServer. Alternatively, CycleServer may be installed directly on the scheduler. Ganglia's gmetad daemon must be configured to serve up XML via its RESTful interface and the CycleServer host must be able to request this XML. By default this is enabled and accessible on port 8652 ( Installation Before beginning, make sure you are logged into your machine as the root user. This is required for the installation process to set CycleServer to start on boot. Download the CycleServer tarball, then extract the contents into a temporary directory. The temporary directory will now contain a cycle_server folder. From this directory you may execute the installation script. If you wish to install CycleServer in the default /opt/cycle_server directory:./install.sh or if you wish to specify an installation directory:./install.sh --installdir /path/to/install/dir 1

4 This installation script will place CycleServer in the desired directory and create a user called "cycle_server" that will be used to run the service. It will also add an init.d script so that CycleServer is started on boot. When the installation script finishes, you should see the following message: CycleServer is installed. Please browse to to complete the installation. Open the provided URL inside of your web browser. It may take a minute for the URL to become available as CycleServer initializes itself, after which you will see the installation wizard appear. Creating an admin user The wizard will prompt you to create a user. This user will have full administrative privileges to CycleServer. Simply enter a user id (such as "admin"), a full name ("CycleServer Administrator") and a password. After initial setup is complete, you may configure Active Directory/LDAP integration if desired. Initial OGS/SGE/etc Cluster Configuration This section of the wizard will guide you through configuring CycleServer to monitor an OGS/SGE cluster. The following values are required: Cluster Name: The name of the cluster. A short but descriptive name is recommended. This cannot be changed later. Cell Name: The cell name of the cluster. This should almost always be set to "default". Hostname: The fully qualified host name of the scheduler node. SSH User: The user that will be used to run remote commands on the scheduler. SSH Key: The absolute path of an RSA key used to connect to the scheduler. The scheduler machine must be configured for passwordless SSH. You may test this by running the following command as the cycle_server user: ssh -i /path/to/rsa_key [email protected] Note that the cycle_server user must own the key file, and it must be readable and writable by only the owner (chmod 600). OGS/SGE Root: The full path to OGS/SGE on the scheduler (for example: /opt/ogs/ogs ). Monitoring: If checked, OGS/SGE monitoring will be enabled. This should checked for this install. 2

5 Interval: How often CycleServer will poll OGS/SGE for new data. This should generally be set to "1m". Initial Ganglia Cluster Configuration This section of the wizard will help you configure CycleServer to monitor a Ganglia cluster through its gmetad daemon. The following values are required: Name: The name of the Ganglia cluster. A short but descriptive name is recommended. If the Ganglia and OGS/SGE clusters contain the same hosts then the cluster names should match. This cannot be changed later. Interval: How often CycleServer will poll Ganglia for new data. This should generally be set to "1m". Daemon: The fully qualified host name of the host running Ganglia's gmetad. If the gmetad is serving XML on a port other than 8652 (the default), then this value should be in hostname:port format. Installing a License Completing the installation wizard will navigate to the "installed applications" page, where the product license can be entered. Under "install a license" you may enter a redemption code or a license key and click the "Install License" button. If you need a license, select the "License Key" tab, copy the license request code, paste it into an and send it to [email protected]. Once a valid licenses is entered, click the CycleServer icon in the upper right-hand corner of the screen to go to the home page. Configuring CycleServer Chef Monitoring CycleServer runs an Apache Qpid message queue which is used to receive Chef data from a custom Chef handler. For instructions on installing and configuring the handler, visit and see the install guide. Note that the handler should be configured to point to the CycleServer machine. Monitoring Additional OGS/SGE/etc Clusters To monitor another OGS/SGE cluster, select "Systems" then "OGS/SGE" from the menu, then click "Configure qmasters" in the upper right-hand corner of the page. This will bring you to a list of your currently configured clusters. Click the "Create" button. This will pop up the cluster configuration dialog. Follow the steps described under the "Initial OGS/SGE Cluster Configuration" section above to set up your new cluster. 3

6 Monitoring Additional Ganglia Clusters To monitor another Ganglia cluster, select "Systems" then "Ganglia" from the menu, then click "Configure masters" in the upper right-hand corner of the page. This will bring you to a list of your currently configured clusters. Click the "Create" button. This will pop up the cluster configuration dialog. Follow the steps described under the "Initial Ganglia Cluster Configuration" section above to set up your new cluster. Upgrading to a New Version To upgrade CycleServer, download the new tarball into a temporary directory and run the following commands as root (replacing /opt/cycle_server with your CycleServer installation directory if necessary): cd /opt/cycle_server./util/upgrade.sh /full/path/to/cycle_server.tar.gz This script will perform the upgrade and restart CycleServer automatically. To verify that the upgrade was successful, open the CycleServer web interface and look at the version number displayed in the lower left-hand corner of the screen. 4
