1. Install Software¶
We will use Software Collections to satisfy majority of the following software requirements:
This tutorial is run from the perspective of an account that has sudo access but is not root.
Enable the EPEL and Software Collections repositories:
- CentOS 6/7
sudo yum install centos-release-scl
- RHEL 6
sudo subscription-manager repos --enable=rhel-server-rhscl-6-rpms # Repository 'rhel-server-rhscl-6-rpms' is enabled for this system.
- RHEL 7
sudo subscription-manager repos --enable=rhel-server-rhscl-7-rpms # Repository 'rhel-server-rhscl-7-rpms' is enabled for this system.
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.
Add Open OnDemand’s repository hosted by the Ohio Supercomputer Center:
- CentOS/RHEL 6
sudo yum install https://yum.osc.edu/ondemand/1.6/ondemand-release-web-1.6-1.el6.noarch.rpm
- CentOS/RHEL 7
sudo yum install https://yum.osc.edu/ondemand/1.6/ondemand-release-web-1.6-1.el7.noarch.rpm
Install OnDemand and all of its dependencies:
sudo yum install ondemand
For some older systems, user ids (UID) may start at
500 and not the
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 # ...
When Installing OnDemand From Source¶
Installing OnDemand from RPMs should provide all of the system dependencies. For users attempting to install OnDemand from source on non-CentOS/RHEL systems, it may be useful to know that OnDemand has several other build and run time dependencies that may need to be installed on the web node.
Note: GCC is a build time dependency and is only required when building OnDemand from source.
