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
