1. Install Software

We will use Software Collections to satisfy majority of the following software requirements:

• Apache HTTP Server 2.4
• Ruby 2.4 with rake, bundler, and development libraries
• Node.js 6
• Git 2.9

Note

This tutorial is run from the perspective of an account that has sudo access but is not root.

1. Enable the EPEL and Software Collections repositories:

   CentOS 6/7

   sudo yum install epel-release centos-release-scl
   

   RHEL 6

   sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
   sudo subscription-manager repos --enable=rhel-server-rhscl-6-rpms
   # Repository 'rhel-server-rhscl-6-rpms' is enabled for this system.
   

   RHEL 7

   sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
   sudo subscription-manager repos --enable=rhel-server-rhscl-7-rpms
   # Repository 'rhel-server-rhscl-7-rpms' is enabled for this system.
   

   Warning

   For RedHat you may also need to enable the Optional channel and attach a subscription providing access to RHSCL to be able to use this repository.

2. Add Open OnDemand’s repository hosted by the Ohio Supercomputer Center:

   CentOS/RHEL 6

   sudo yum install https://yum.osc.edu/ondemand/1.4/ondemand-release-web-1.4-1.el6.noarch.rpm
   

   CentOS/RHEL 7

   sudo yum install https://yum.osc.edu/ondemand/1.4/ondemand-release-web-1.4-1.el7.noarch.rpm
   

3. Install OnDemand and all of its dependencies:

   sudo yum install ondemand
   

Warning

The nginx RPM used by ondemand will upgrade the nginx RPMs provided by EPEL, if they are installed.

Note

For some older systems, user ids (UID) may start at 500 and not the expected 1000. If this true for your system, you will need to modify the /etc/ood/config/nginx_stage.yml configuration file to allow these users access to OnDemand:

# /etc/ood/config/nginx_stage.yml
---

# ...

# Minimum user id required to generate per-user NGINX server as the requested
# user (default: 1000)
#
min_uid: 500

# ...
