PHYDO demo server

PHYDO Demo Server at IUB

TEMP SECONDARY DEMO SERVER

Currently there is a demo server running version displayed at OR 2016.

Web server: helium.dlib.indiana.edu:8200 (temporarily displacing the tomcat service described below)
Solr: helium.dlib.indiana.edu:8985
Fedora: helium.dlib.indiana.edu:8986 

Access

Hostname: helium.dlib.indiana.edu

• SSH will only be allowed from IU networks, so a VPN connection will be required. See https://kb.iu.edu/d/ajrq

Deployment

TODO Update user/group to phydo for production instance.

User/group: hydradam:hydradam

• Directories used for deployment should be owned by the hydradam user
• Any Rails applications or Tomcat instances should be run as the hydradam user
• The hydradam user is in the rvm group in case it needs to install anything Ruby related or own a gemset
• Sudo access should allow you to become hydradam from a shell if necessary

Location: /srv/hydradam

• Owned by user/group hydradam:hydradam
• Can be symlinked to satisfy any deployment requirements (i.e., symlinked from /opt)
• For now this is just a directory in the root filesystem but Brian will get a real data disk to mount /srv to, so for now we have to be a little careful about cleaning up large testing objects.

Ports:

• Port 8500 has been opened to firewalls for running the Rails application
• Port 8200 has been opened to firewalls for running/managing a Tomcat instance for Fedora and Solr when required

Fedora and Solr

• For now we can keep it simple by just starting Jetty on port 8983
• When we want a real production-like deployment using Tomcat we have port 8200 open for management and troubleshooting
