===== Installation from Debs =====

Check the Installation Guide for more details.

1) **Install the GridWay Core**: The binary DEB package gridway-core installs GridWay with a multi-user configuration.

1.1) Install DEB dependencies: libdb4.8.

1.2) Post-install configuration:
  * All of the GridWay users must be members of the gwusers UNIX group.
  * GridWay users must export the $GW_LOCATION environmental variable:

  export GW_LOCATION=/usr

  * You can create a profile file for gwusers group, such as:

  for i in `groups`; do
   if [ "$i" = 'gwusers' ]; then
    GLOBUS_LOCATION=/usr
    GW_LOCATION=/usr
    export GLOBUS_LOCATION GW_LOCATION
   fi
  done

  * Some privileges are required to be set in the /etc/sudoers file. Please add the below lines.

  Defaults:gwadmin !requiretty
  # User alias specification (GridWay)
  Runas_Alias GWUSERS = %gwusers
  Defaults>GWUSERS env_keep="GW_LOCATION"
  #GridWay entries
  gwadmin ALL=(GWUSERS) NOPASSWD: /usr/bin/grid-proxy-info *

The source DEB package gridway-core enables you to build the binary DEB.
  * Build DEB dependencies: debhelper, gcc, and default-jdk.

2) **Install the GridWay MADs**

2.2a) Post-install configuration:
  * This DEB provides a basic configuration of the MADs through the file /usr/etc/gwd.conf (check the Configuration Guide).
  * You must configure the available hosts for your GridWay instance (see the example file /usr/etc/gram5_hosts.list).
  * GridWay users must export the $GLOBUS_LOCATION environmental variable:

  export GLOBUS_LOCATION=/usr

  * Some privileges are required to be set in the /etc/sudoers file. Please add the following lines.

  Defaults>GWUSERS env_keep="GW_LOCATION GLOBUS_LOCATION"
  #GridWay entries (GT5 MAD)
  gwadmin ALL=(GWUSERS) NOPASSWD: /usr/bin/gw_em_mad_gram5 *
  gwadmin ALL=(GWUSERS) NOPASSWD: /usr/bin/gw_tm_mad_ftp *

The source DEB package gridway-gt5 enables you to build the binary DEB.
  * Build DEB dependencies: debhelper, gcc, libglobus-common-dev, libglobus-gram-client-dev, libglobus-ftp-client-dev, libglobus-gass-copy-dev and grid-packaging-tools.

2b) GridWay MADs for OGSA-BES endpoints: The binary DEB package gridway-bes installs the GridWay MAD to interface with OGSA-BES services, as well as an static information MAD and a dummy transfer MAD are provided.

2.1b) Install DEB dependencies: gridway-core, libxmlbeans-java, libaxis-java, libwsdl4j-java, libxml-security-java, libxalan2-java and default-jre.
  * Other dependencies (non DEB): gridsam-schema, OMII security utils and wss4j (check the default location in GW_em_mad_bes).

2.2b) Post-install configuration:
  * This DEB provides a basic configuration of the MADs through the file /usr/etc/gwd.conf (check the Configuration Guide). Set up your GridFTP server.
  * You must configure the available hosts for your GridWay instance (see the example file /usr/etc/BES_hosts.list).
  * GridWay users must export the $GLOBUS_LOCATION environmental variable: 

  export GLOBUS_LOCATION=/usr

  * Some privileges are required to be set in the /etc/sudoers file. Please add the following lines.

  Defaults>GWUSERS env_keep="GW_LOCATION GLOBUS_LOCATION"
  #GridWay entries (OGSA-BES MAD)
  gwadmin ALL=(GWUSERS) NOPASSWD: /usr/bin/GW_em_mad_bes *
  gwadmin ALL=(GWUSERS) NOPASSWD: /usr/bin/gw_tm_mad_dummy *

  * MyProxy is used for managing security credentials. Create a $HOME/.myproxy file, where the first line is the hostname of the MyProxy server, the second line is the username and the last line is the password.
  * Configure the client-config.wsdd and crypto.properties files in $GW_LOCATION/etc/.

The source DEB package gridway-BES enables you to build the binary DEB.
  * Build DEB dependencies: debhelper, libaxis-java, libxmlbeans-java, libxalan2-java and default-jdk.
  * Other dependencies (non DEB): gridsam-schema (check the default location in Makefile and gw_em_mad_bes.sh).
