Openvswitch CENTOS6. X Installation and use

Summary

Openvswitch Virtual Switch centos6.x compiled installation and simple VLAN configuration

First, build a compilation environment

Install the compilation environment

#yum install gcc make python-devel openssl-devel kernel-devel graphviz kernel-debug-devel autoconf automake Rpm-bui LD Redhat-rpm-config Libtool

compiling RPM is recommended for normal users

Download Create compiled directory script

$wget Ftp://ftp.owlriver.com/pub/local/COLUG//RPM-build-tree.txt

Execute script

$sh Rpm-build-tree.txt

The following directory will be created in the current user home directory

Rpmbuild├──build├──buildroot├──rpms├──sources├──specs└──srpms

second, compile openvswitch rpm Package

# #切换至家目录 $CD ~# #下载openvswitch源码包 $wget http://openvswitch.org/releases/openvswitch-2.3.1.tar.gz $CP openvswitch-2.3.1.tar.gz rpmbuild/sources/$tar xvf openvswitch-2.3.1.tar.gz$cd openvswitch-2.3.1# #编译内核 $cp rhel/ Openvswitch-kmod.files ~/rpmbuild/sources/$rpmbuild-bb rhel/openvswitch-kmod-rhel6.spec # #编译openvswitch rpm$ RPMBUILD-BB Rhel/openvswitch.spec

After compilation, the RPM package is located in

ll ~/rpmbuild/rpms/x86_64/total 11440-rw-rw-r--. 1 Firxiao firxiao 1223288 Dec 05:50 kmod-openvswitch-2.3.1-1.el6.x86_64.rpm-rw-rw-r--. 1 Firxiao firxiao 2640440 Dec 06:01 openvswitch-2.3.1-1.x86_64.rpm-rw-rw-r--. 1 Firxiao firxiao 7846548 Dec 06:01 openvswitch-debuginfo-2.3.1-1.x86_64.rpm

Upload openvswitch-2.3.1-1.x86_64.rpm kmod-openvswitch-2.3.1-1.el6.x86_64.rpm to VM1, vm2

Installing with Yum

#yum Install openvswitch-2.3.1-1.x86_64.rpm kmod-openvswitch-2.3.1-1.el6.x86_64.rpm

Start the service

#/etc/init.d/openvswitch start

after configuring the NIC

#service Network Restart

iv. Test Configuration

Use 172.16.0.0/24 on VM2 on VM1 to communicate with each other

Communication with vlan100 192.168.100.0/24 is also possible two networks are isolated from one another
