In this article, we aim to provide a comprehensive guide on how to install Open vSwitch on Ubuntu. Open vSwitch, or OVS, is an open-source virtual switch designed to enable network automation while supporting standard management interfaces and protocols. For this tutorial, we will be using the Ubuntu 20.04 OS release.
Before starting, ensure that you have root access or sudo privileges to follow through with these instructions.
Step 1: Download OVS Binaries
Start the process by downloading the Open vSwitch binaries. Click Here to download the required files.
Step 2: Extract Files
Use the following command to extract the downloaded tar file:
tar -xvf openvswitch-3.2.0.tar.gz
Ensure that you replace "openvswitch-3.2.0.tar.gz" with the name of your actual downloaded file.
Step 3: Build Open vSwitch
In the next step, navigate to the extracted binary directory and run the
cd openvswitch-3.2.0 ./boot.sh
Step 4: Run the configuration script
Now we run the
configure script which should create the
Execute the above command in your terminal. This will check for any dependencies that you might need to address.
Step 5: Make and Install
Once the configuration process runs without any errors, use the
make install commands. These commands will compile and install OVS on your system.
make && make install
Please note, that compiling might take a bit of time - so be patient.
Step 6: Add Open vSwitch scripts to $PATH
The PATH environment variable is a colon-delimited list of directories that your shell searches through when you enter a command. To execute OVS binaries from anywhere in the system, you should add the path of the OVS scripts to your PATH variable.
First, check if the path to the Open vSwitch script directory is already included in your PATH:
grep -qxF ‘export PATH=$PATH:/usr/local/share/openvswitch/scripts;’ ~/.bashrc
If this command does not output anything, you can add the path to your
.bashrc file with this command
echo ‘\nexport PATH=$$PATH:/usr/local/share/openvswitch/scripts;’ >> ~/.bashrc;
Step 7: Update the PATH variable
To load the updated PATH, run the following command in the terminal.
With this, your installation process should be complete.
It is advisable to reboot the system at this point to ensure all the changes have taken effect.
While running any command, if you receive a "Permission Denied" error, try using "sudo" at the start of the command.
After you reboot, you should have a working Open vSwitch installation and will be ready to move forward and learn about how to configure and use it. Open vSwitch has a multitude of uses. With it, you can manage networking more efficiently and automate network tasks while utilizing standard management interfaces and protocols.
Verifying the Installation
To ensure that Open vSwitch has been installed correctly, you can use the
ovs-vsctl command to check its version. Type the following command in your terminal:
The command will display the version of Open vSwitch installed on your system if the installation process was successful.
ovs-vsctl (Open vSwitch) 3.2.0 Compiled Jun 20 2021 09:50:19
This tells you that v3.2.0 was installed successfully.
This guide walked you through the process of installing Open vSwitch on Ubuntu 20.04. By following the steps outlined above, you are now ready to deploy and test your virtual networking projects.
Open vSwitch is a powerful tool, and mastering its capabilities can be of great use to anyone seeking a career in networking or system administration. I hope this article helped guide you through the installation process.
