nm-workspace

How to install the node manager (unitl we integrate it into the installer)

Standalone, eg. for a Docker container:

1. bash nm-installer.sh

2. service nm-httpd start

3. curl --insecure http:///esgf-nm - should return a default response

4. esgf-nm-ctl start

5. esgf-nm-ctl status – should keep running

6. If any problems check logs either in /esg/logs or /var/log/httpd/error_log

With ESGF:

1. Install ESGF – the choice of peer group is now crucial

A)  If in a private vm environment using the demonet named instances, use esgf-demo as your peer group

B)  If on an open node out on internet to participate in the test federation, use esgf-test as your peer group (confirm its set in esgf.properties)


      i) When you’re ready to run a test node as a supernode, I’ll need to update the supernode list on aims1 with the fqdn - contact Sasha (ames4@llnl.gov).

C)  A transistion to esgf-prod is TBD

2. git clone the nm-workspace repo

3. Strongly recommended to back up your current esgf installation in case anything goes wrong. The most crucial file to back up is /etc/httpd/conf/esgf-httpd.conf as the nm-installer does change this

4. export HAS_ESGF=1

5. bash nm-installer.sh

The control files referenced in steps 5, 7, 8 are put into /usr/local/bin (path assumed)

6. esg-node restart

7. curl http://localhost/esgf-nm - should work (if doesn't there's a manual setup)

8. esgf-nm-ctl start

9. esgf-nm-ctl status – should keep running

10. If any problems check logs either in /esg/logs or /var/log/httpd/error_log

11. If you are running a membernode: python /usr/local/esgf-nodemgr-doc/code/server/member_node_cmd.py add <project> 0

  For now the name of the project isn't relevant, but might be in the future when the node manager manages configurations for "virtual organizations"

Troubleshooting:

• previous versions of esg-node automatically call "update_apache_conf". If step (6) above does not work, comment line 5223 (or check first) of esg-node to disable the update.
