Bundle Installation on RedHat Enterprise Linux Variants¶
note:: For older CentOS 7 installation see Bundle Installation on CentOS 7
perfSONAR combines various sets of measurement tools and services bundled in different useful ways. RPMs are available that install the bundles described in perfSONAR Installation Options. The steps in the remaining sections of this document detail the steps required for installing these bundles.
Alma 8, Alma 9, Rocky 8 or Rocky 9 x86_64 installations are supported. Other RedHat-based operating systems may work, but are not officially supported at this time.
See Hardware Requirements for hardware requirements and more.
Installing a graphical/desktop environment with perfSONAR is not supported. These environments generally come with a Network Manager that conflicts with the way that perfSONAR is tuning the network interface parameters. We recommend doing only server grade OS installs.
Step 1: Configure DNF¶
If your system is using dnf/yum priorities make sure that repositories required for perfSONAR are higher priority than anything else to avoid conflicts with older versions. Please note that yum maintainers do not recommend using priorities.
The process configures dnf to point at the necessary repositories to get packages needed for perfSONAR. You will need to follow the steps below as privileged user:
All commands work on both EL8 and EL9 based operating systems unless otherwise indicated
Install the EPEL RPM:
dnf install epel-release
EL8-only Enable the PowerTools repository on an EL8 system:
dnf config-manager --set-enabled powertools
EL9-only Enable the CBR repository on an EL9 system:
dnf config-manager --set-enabled crb
EL8-only Install the perfsonar-repo RPM for EL8:
dnf install http://software.internet2.edu/rpms/el8/x86_64/latest/packages/perfsonar-repo-0.11-1.noarch.rpm
EL9-only Install the perfsonar-repo RPM for EL9:
dnf install http://software.internet2.edu/rpms/el9/x86_64/latest/packages/perfsonar-repo-0.11-1.noarch.rpm
Refresh dnf’s cache so it detects the new RPMS:
dnf clean all
Step 2: Install a Bundle¶
CHOOSE ONE of the following bundles and see perfSONAR Installation Options page for more information about what these bundles are.
dnf install perfsonar-tools
perfSONAR Test Point:
dnf install perfsonar-testpoint
dnf install perfsonar-core
dnf install perfsonar-archive
dnf install perfsonar-toolkit
In addition to any of the bundles above you may also optionnally choose to install one or more of our add-on packages (these are automatically added on the perfsonar-toolkit bundle):
dnf install perfsonar-toolkit-security- Adds default firewall rules and installs fail2ban
dnf install perfsonar-toolkit-servicewatcher- Adds a cron job that checks if services are still running.
dnf install perfsonar-toolkit-sysctl- Adds default sysctl tuning settings
dnf install perfsonar-toolkit-systemenv-testpoint- Configures auto-update and set some default logging locations
Step 3: Verify Tuning Parameters¶
Step 3 can be ignored for perfsonar-toolkit package installation as its instructions are included and run automatically
It is important to make sure that your host is properly tuned for maximum TCP performance on the WAN. You should verify that htcp, not reno, is the default TCP congestion control algorithm, and that the maximum TCP buffers are big enough for your paths of interest. You can also re-run this script any time you need e.g. when host interface speed changes.
Configure perfSONAR sysctl settings
If the optional package was installed, then run:
Advanced Manual Tuning

Step 4: Firewall and Security Considerations¶
If you have installed the perfsonar-toolkit-security package, then you can configure the firewalld / IPTable entries by running:
The package also installs fail2ban.
Or, if you would like to configure the rules manually, then please review the document here on the ports that need to be open.
Additionally, pscheduler allows you to limit the parameters of tests such as duration and bandwidth based on the requesters IP address. It does this through the
ESnet provides a file containing all R&E subnets, which is updated nightly. Instructions on how to download this file and configure pScheduler to use it are described on the page Limiting Tests to R&E Networks Only.
Note that the perfsonar-toolkit-security package is automatically included in the perfsonar-toolkit bundle.
Step 5: Auto updates¶
You can also enable dnf ‘auto updates’ to ensure you always have the most current and hopefully most secure packages. To do this follow the steps in Managing Automatic Updates from the Command-Line.
Automatic updates are enabled by default in the perfSONAR Toolkit.
Step 6: Service Watcher¶
perfsonar-toolkit-servicewatcher installs scripts that check if important processes are running and restarts if they have stopped unexpectedly.
The install automatically configures cron to run the service_watcher regularly.
To run the script manually, run:
Step 7: Register your services¶
Note: this step can be done through the web interface if the perfsonar-toolkit bundle was installed. See Updating Administrative Information.
No actual configuration is required but filling fields such as administrator_email, site_name, city, country, latitude, longitude, etc. are highly recommended. You can add these by removing the leading # of any property and filling it out with a proper value for your host. Changes will be picked-up automatically without need for any restarts.
Step 8: Starting your services¶
All services should be started after install. Additionally, you can start all the services by rebooting the host since all are configured to run by default. In order to check services status issue the following commands:
systemctl status pscheduler-scheduler systemctl status pscheduler-runner systemctl status pscheduler-archiver systemctl status pscheduler-ticker systemctl status psconfig-pscheduler-agent systemctl status owamp-server systemctl status perfsonar-lsregistrationdaemon
If they are not running you may start them with appropriate init commands as a root user. For example:
systemctl start pscheduler-scheduler systemctl start pscheduler-runner systemctl start pscheduler-archiver systemctl start pscheduler-ticker systemctl start psconfig-pscheduler-agent systemctl start perfsonar-lsregistrationdaemon systemctl start owamp-server

Configuring an Archive¶
If you installed the perfsonar-archive bundle see the following document Deploying a Central Measurement Archive
