Centos7安装Openvswitch

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
