Installing ROS 2 via RPM Packages¶
Table of Contents
RPM packages for ROS 2 Rolling Ridley are currently available for RHEL 8. The Rolling Ridley distribution will change target platforms from time to time as new platforms are selected for development. The target platforms are defined in REP 2000 Most people will want to use a stable ROS distribution.
Make sure you have a locale which supports
If you are in a minimal environment (such as a docker container), the locale may be something minimal like
We test with the following settings. However, it should be fine if you’re using a different UTF-8 supported locale.
locale # check for UTF-8 sudo dnf install langpacks-en glibc-langpack-en export LANG=en_US.UTF-8 locale # verify settings
You will need to enable the EPEL repositories and the PowerTools repository:
sudo dnf install 'dnf-command(config-manager)' epel-release -y sudo dnf config-manager --set-enabled powertools
Next, download the ROS 2 .repo file:
sudo dnf install curl sudo curl --output /etc/yum.repos.d/ros2.repo http://packages.ros.org/ros2/rhel/ros2.repo
Then, update your metadata cache.
DNF may prompt you to verify the GPG key, which should match the location
sudo dnf makecache
Desktop Install (Recommended): ROS, RViz, demos, tutorials.
sudo dnf install ros-rolling-desktop
ROS-Base Install (Bare Bones): Communication libraries, message packages, command line tools. No GUI tools.
sudo dnf install ros-rolling-ros-base
If you installed
ros-rolling-desktop above you can try some examples.
In one terminal, source the setup file and then run a C++
source /opt/ros/rolling/setup.bash ros2 run demo_nodes_cpp talker
In another terminal source the setup file and then run a Python
source /opt/ros/rolling/setup.bash ros2 run demo_nodes_py listener
You should see the
talker saying that it’s
Publishing messages and the
I heard those messages.
This verifies both the C++ and Python APIs are working properly.
Continue with the tutorials and demos to configure your environment, create your own workspace and packages, and learn ROS 2 core concepts.
The default middleware that ROS 2 uses is
Cyclone DDS, but the middleware (RMW) can be replaced at runtime.
See the guide on how to work with multiple RMWs.
