Installation

Installation Process

Installation of glideinWMS is a multi-step process:

  1. Components and Pre-requisites: Includes a consolidated table of requirements for each server.
  2. The glidein WMS Collector and collocated glidein Factory node
  3. The glidein pool Collector node
  4. One or more scheduler nodes for user submission
  5. The Glidein Frontend
  6. Submitting a job

The above process should suffice for typical installs. More information can be found below.

Configuration based installer

Alternatively, you can use the Configuration based installer. This approach requires filling out a configuration file (ini file) with all the required fields up front. Once this is done, you can install each component using the tool and this ini file. It prevents the frustration of running the Q&A installer multiple times in case of errors.

Important Note: You can only use either the Q&A installer to install all components or the configuration based installer to install all components. You cannot mix installations by installing partially with the Q&A installer and partially with the configuration installer. Also, note that both installers assume you are performing a full installation of all components. For upgrades, see the upgrade guide or contact glidein support.

Possible Configurations

While the documents presented here assume you will install each component on a different machine, there is nothing preventing you from installing all of them on fewer machines, or even on one machine only (excluding GCB, but you should not use it anyhow). Note that only configurations with the WMS collector and factory on the same node are supported. Also note that worker nodes must be able to access the web server on the factory node in order to download neccessary files. It should be noted that it is possible to install the glideinWMS across administrative boundaries (i.e. you will only install part of the glideinWMS infrastructure). See the OSG section below for an example.

Several possible configurations are below:

Two Server configuration (recommended minimum):

Three Server configuration (recommended for 1000+ glideins)

One Server configuration (Use only for test installs)

OSG Factory configuration

Members of the Open Science Grid can use the OSG factory at UCSD. In this case, only the following installation is necessary:

See OSG Glidein Factory for more details on how to use this setup.
