CoG Installation or Upgrade

Typically, CoG is installed on an ESGF node as part of the full ESGF installation suite. Nevertheless, if desired CoG can be installed or upgraded standalone by following the steps described in this document.

• Stop the ESGF node, but restart postgres:

  • sudo /usr/local/bin/esg-node stop

  • sudo /etc/init.d/postgresql start

• Backup the CoG source tree and data, so that you can recover in case anything goes wrong.:

  • cd

  • sudo cp -R /usr/local/cog/ ./cog

  • export PATH=/usr/local/pgsql/bin:$PATH

  • pg_dump -p 5432 -U dbsuper cogdb > ./cogdb_backup.sql (insert your dbsuper password)

  • pg_dump -p 5432 -U dbsuper esgcet > ./esgcet_backup.sql (insert your dbsuper password)

• Checkout the latest version of the CoG installation script from the devel branch (since the script is not going to be updated in the master branch untill the next ESGF release):

  • cd

  • wget ‘https://raw.githubusercontent.com/ESGF/esgf-installer/devel/cog/esg-cog’

  • check that the script containes the desired CoG version - at this time:

    • VERSION=v3.9.0

  • sudo cp esg-cog /usr/local/bin

• Run the script:

  • cd /usr/local/bin

  • sudo ./esg-cog

• Let the installation complete, hopefully without errors. Then stop postgres and restart the node:

  • sudo /etc/init.d/postgresql stop

  • sudo /usr/local/bin/esg-node start
