1. Install Software¶
Open OnDemand uses these packages, among many others.
Ruby 2.7 with rake, bundler, and development libraries
Node.js 14
Some operating systems use Software Collections to satisfy these.
Note
This tutorial is run from the perspective of an account that has sudo access but is not root.
Warning
Be sure to check Supported Operating Systems before proceeding with install to verify you are on a supported operating system.
Warning
If you are an administrator responsible for Open OnDemand, you are now an administrator of Apache Httpd as well. As such, you should get comfortable with it as from time to time you will have to troubleshoot it.
1. Enable Dependencies¶
sudo yum install centos-release-scl epel-release
sudo dnf config-manager --set-enabled powertools
sudo dnf install epel-release
sudo dnf module enable ruby:3.0 nodejs:14
sudo dnf config-manager --set-enabled crb
sudo dnf install epel-release
Warning
You may also need to enable the Optional channel and attach a subscription providing access to RHSCL to be able to use this repository.
sudo yum install epel-release
sudo subscription-manager repos --enable=rhel-server-rhscl-7-rpms
sudo dnf install epel-release
sudo dnf module enable ruby:3.0 nodejs:14
sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
sudo dnf install epel-release
sudo subscription-manager repos --enable codeready-builder-for-rhel-9-x86_64-rpms
2. Add repository and install¶
sudo yum install https://yum.osc.edu/ondemand/3.0/ondemand-release-web-3.0-1.noarch.rpm sudo yum install ondemandsudo apt install apt-transport-https ca-certificates wget -O /tmp/ondemand-release-web_3.0.0_all.deb https://apt.osc.edu/ondemand/3.0/ondemand-release-web_3.0.0_all.deb sudo apt install /tmp/ondemand-release-web_3.0.0_all.deb sudo apt update sudo apt install ondemand
3. Start services¶
sudo systemctl start httpd24-httpd sudo systemctl enable httpd24-httpdsudo systemctl start httpd sudo systemctl enable httpdsudo systemctl start apache2 sudo systemctl enable apache2
4. Verify installation¶
Now that Open OnDemand is installed and Apache is running, it should be serving a public page telling you to come back here and setup authentication.
If this is the case - then you need to add authentication. The installation will not move forward without adding authentication.
After adding authentication, but before actually testing that it works, you should secure your Apache. This way you never send credentials over plain HTTP.
You may also want to enable SELinux.
If you’re seeing the default Apache page (Ubuntu users will) you will have to debug virtualhosts and likely configure a servername.
Building From Source¶
Building from source is left as an exercise to the reader.
It’s not particularly difficult to build the code, but installing it with all the various files is. Should you be interested,
review the Dockerfile and packaging specs for what would be involved.
If you’d like a package built for a system that we don’t currently support, feel free to open a ticket!
