Installation Openvswitch LTS in CentOS 7

Openvswitch LTS in CentOS 7.md

Based on this post: https://n40lab.wordpress.com/2016/03/02/openvswitch-lts-in-centos-7 The most recent release from the LTS series: http://openvswitch.org/releases/openvswitch-2.5.4.tar.gz

Instructions:

As the root user let’s install some packages:

yum -y install wget openssl-devel gcc make python-devel openssl-devel kernel-devel graphviz kernel-debug-devel autoconf automake rpm-build redhat-rpm-config libtool python-twisted-core python-zope-interface PyQt4 desktop-file-utils libcap-ng-devel groff checkpolicy selinux-policy-devel

Add a new user and switch to that user:

adduser ovs

su - ovs

Download source code and prepare the build environmen.

mkdir -p ~/rpmbuild/SOURCES

wget http://openvswitch.org/releases/openvswitch-2.5.4.tar.gz

cp openvswitch-2.5.4.tar.gz ~/rpmbuild/SOURCES/

tar xfz openvswitch-2.5.4.tar.gz

Build the RPM package (no testing) and exit.

rpmbuild -bb --nocheck openvswitch-2.5.4/rhel/openvswitch-fedora.spec

exit

As root, we’ll install the RPM package.

yum localinstall /home/ovs/rpmbuild/RPMS/x86_64/openvswitch-2.5.4-1.el7.centos.x86_64.rpm -y

Finally start the openvswitch service and check that it’s running.

systemctl start openvswitch.service

systemctl is-active openvswitch

active --> Ok

Make openvswitch service to start at boot time:

systemctl enable openvswitch

Let’s check that the command-line tools are ready:

ovs-vsctl -V

ovs-vsctl (Open vSwitch) 2.5.2

DB Schema 7.12.1

the simplest install procedure I've seen...thanks

Thanks a lot.

Awesome. Thank you. Still works with Cents 7.4

Thank you.

Again, thanks. This post has saved me a lot of trouble. So perfectly concise.

It works,Thank you.

@umardx
Is the RPM "Portable"? I.E. can I build it once for CentOS 7.4 and then push it to all of my hypervisors?
Or are the yum packages installed or the ovs user created above a dependency for this RPM?

@c0dyhi11 I'm not sure, but as long as your CentOS major version 7, I think it will be fine.

Nice post. Works great for beginners

Thanks a lot!

Works perfectly in CentOS 7.4.1708! Thanks!

I think it would be fair to add the original reference:https://n40lab.wordpress.com/2016/03/02/openvswitch-lts-in-centos-7/

Can I do the same by cloning the OVS from this github repo https://github.com/doonhammer/ovs?
Also How can I install OVN along with OVS?

Used the same process to install 2.5.9 on centos 7.7

Build and install worked fine.
