1. Install Software From RPM¶
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 Software Collections repositories on CentOS/RHEL 7 only:
- CentOS 7
sudo yum install centos-release-scl
- 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:
sudo yum install https://yum.osc.edu/ondemand/1.8/ondemand-release-web-1.8-1.noarch.rpm
Install OnDemand and all of its dependencies:
sudo yum install ondemand
(Optional) Install OpenID Connect with Dex package
mod_auth_openidcDNF module must be enabled on RHEL/CentOS 8 only
sudo dnf module enable mod_auth_openidc:2.3
If authenticating against LDAP or wishing to evaluate OnDemand using ood user, you must install ondemand-dex. See Add LDAP Support for details on configuration of LDAP.
sudo yum install ondemand-dex
(Optional) Install OnDemand SELinux support if you have SELinux enabled. For details see SELinux
sudo yum install ondemand-selinux
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 # ...
