New and returning installations

Regardless of whether you have installed and administered an ESGF node previously, please read the following document on ESGF policies, as this should influence what type of installation you should do:

http://esgf.llnl.gov/media/pdf/ESGF-Policies-and-Guidelines-V1.0.pdf

Latest version of ESGF available in devel

2.7.0-devel-release

Latest version of ESGF available in master

2.6.9-master-release

Important Note

ESGF has an auto-installer which is capable of automating installs for all known valid combinations of roles (all, data, data+compute+index,...), and you are strongly advised to use the auto-installer, in order to eliminate problems due to due to errant keystrokes etc. You can find the page providing details about the autoinstaller here. If this doesn't work for you, or if you prefer to do an expert-install, follow the documentation given below.

Installation Procedure

Platform

RHEL6; CentOS6; Scientific Linux 6

Selinux

selinux needs to be set to Disabled. This can be done by ensuring that the line SELINUX=disabled is present and uncommented in the /etc/sysconfig/selinux file. To confirm, reboot the machine and run getenforce; the output should be Disabled.

Unix User

You must be root or effectively root to run this program, prefixing the command with sudo will not allow the use of needed environment variables! If you must use sudo, do so only to become root proper then source your user's .[bash]rc file so that root has its environment set accordingly! Or you can more simply become root using sudo's "-s" flag.

Prerequisites

  • Ports to open: 80, 443, (GridFTP: 2811, 50000-51000), (MyProxy: 7512)
  • During the installation process, you'll be asked for a globus username and password. You'll need to sign up for a globusonline account beforehand, and provide the username and password when asked for it. You can sign up for an account at https://www.globus.org/SignUp

One way to clear previous installations is via the esg-purge.sh script. For example, to do a full uninstall (don't forget to exit the root shell afterwards in order to drop remaining ESGF-related environment variables and functions, before starting the new install):

cd /usr/local/bin
source /usr/local/bin/esg-purge.sh && esg-purge all && rm -f /etc/yum.repos.d/esgf.repo

Download and Execute the Bootstrap Script

First of all:

script -a install.log # don't forget to issue exit at the end of the installation. 
cd /usr/local/bin

To setup the latest 'devel' install

wget -O esg-bootstrap http://distrib-coffee.ipsl.jussieu.fr/pub/esgf/dist/devel/2.7/0/esgf-installer/esg-bootstrap --no-check-certificate  
chmod 555 esg-bootstrap  
./esg-bootstrap --devel   

To setup the latest 'master' install

wget -O esg-bootstrap http://distrib-coffee.ipsl.jussieu.fr/pub/esgf/dist/2.6/9/esgf-installer/esg-bootstrap --no-check-certificate  
chmod 555 esg-bootstrap  
./esg-bootstrap    

Check Installer Script Version

esg-node --version
Version: v2.6.9-master-release
Release: Asgard
Earth Systems Grid Federation (http://esgf.llnl.gov)
ESGF Node Installation Script

Start the installation process

esg-node --set-type [data|compute|idp|index|all]
esg-node --install

Use script instead of tee to log the installation. tee can cause configuration files corruption. Make sure you specify the type without square bracket or pipe.

Some other notes

If you plan to publish CMIP6 data make sure you answer Y to the question regarding that (not a default).

As we are refactoring the node manager, the "peer with "supernode" question is no longer relevant. Everyone can answer 'N' to the question, but it would not be harmful if the question is skipped.

Tier 1 IDP only - We encourage all sites to deploy the SLCS service so please answer Y.

Post installation

  • Required to restart the node after installing: esg-node restart

Upgrade Procedure

Unix User

You must be root or effectively root to run this program, prefixing the command with sudo will not allow the use of needed environment variables! If you must use sudo, do so only to become root proper then source your user's .[bash]rc file so that root has it's environment set accordingly! Or you can more simply become root using sudo's "-s" flag.

Stop the Node

cd /usr/local/bin
esg-node stop

Clean the webapps directory

Please do this compulsorily, in order to have consistent behavior upon upgrading.

rm -fr /usr/local/tomcat/webapps/*
rm -fr /usr/local/src

Download and Execute the Bootstrap Script

To upgrade to a 'devel' install

cd /usr/local/bin
wget -O esg-bootstrap http://distrib-coffee.ipsl.jussieu.fr/pub/esgf/dist/devel/2.6/6/esgf-installer/esg-bootstrap --no-check-certificate  
chmod 555 esg-bootstrap  
./esg-bootstrap --devel   

To upgrade to a 'master' install

wget -O esg-bootstrap http://distrib-coffee.ipsl.jussieu.fr/pub/esgf/dist/2.6/8c/esgf-installer/esg-bootstrap --no-check-certificate  
chmod 555 esg-bootstrap  
./esg-bootstrap    

Check Installer Script Version

esg-node --version
Version: v2.6.9-master-release
Release: Asgard
Earth Systems Grid Federation (http://esgf.llnl.gov)
ESGF Node Installation Script

Start the installation process

script -c 'esg-node --upgrade' upgrade.log

Primary Configuration

  • Tier 1 IDP only - We encourage all sites to deploy the SLCS service so please answer Y.

Expert Options

  • You can specify a local mirror for use, by specifying the --use-local-mirror option. You'll be then prompted interactively for a mirror url.
  • Due to any transient network/system-availability issue, if you are not able to download the bootstrap from the primary mirror, you can obtain them from other mirrors i.e. CEDA, LIU, or AIMS. The bootstrap scripts specific to the mirrors are called esg-bootstrap.ceda, esg-bootstrap.liu, and esg-bootstrap.aims respectively. Note that you have to save them with their original names, as their checksums differ. For instance, to download the bootstrap from AIMS, and execute it, you would do the following:
wget -O esg-bootstrap http://distrib-coffee.ipsl.jussieu.fr/pub/esgf/dist/2.6/5/esgf-installer/esg-bootstrap --no-check-certificate 
chmod 555 esg-bootstrap.aims
./esg-bootstrap.aims

Post-installation

For self-generated certificates, install them like this:
(Note: Do not worry about warnings/errors during the node stop)

./esg-node stop
./esg-node --install-keypair /etc/tempcerts/hostcert.pem /etc/tempcerts/hostkey.pem
    For the CA chain question, use /etc/tempcerts/cacert.pem
./esg-node start

If you have signed certificates, use those instead:

./esg-node stop
./esg-node --install-local-certs
./esg-node --install-keypair /etc/esgfcerts/hostcert.pem /etc/esgfcerts/hostkey.pem

If your certificates were signed by:
The IPSL CA, use /etc/grid-security/certificates/0597e90c.0.
The NSC CA, use /etc/grid-security/certificates/cd6ccc41.0.
The ANL CA, use /etc/grid-security/certificates/99eb76fc.0.

When prompted, restart the node with ./esg-node restart.

You can’t perform that action at this time.
