Open vSwitch 2.9.2 创建 RPM 安装包

1.安装依赖环境

yum install gcc make python-devel openssl-devel graphviz autoconf automake rpm-build redhat-rpm-config libtool 

2.下载 kernel 源码：

yum install "kernel-devel-uname-r == $(uname -r)"

3.创建rpmbuild目录结构

mkdir rpmbuild/{BUILD,SOURCES,SPECS,RPMS,BUILDROOT} -pv

4.下载源码，解压，编译

cp openvswitch-2.9.2.tar.gz rpmbuild/SOURCES/

tar -xvf openvswitch-2.9.2.tar.gz

cp openvswitch-2.9.2/rhel/openvswitch.spec rpmbuild/SPECS/

cp openvswitch-2.9.2/rhel/openvswitch-kmod-rhel6.spec rpmbuild/SPECS/

5.编译Open vSwitch 2.9.2 用户态模块

rpmbuild -bb rpmbuild/SPECS/openvswitch.spec --nocheck

6.编译Open vSwitch 2.9.2 内核态模块

rpmbuild -bb rpmbuild/SPECS/openvswitch-kmod-rhel6.spec

DPDK编译：

cd dpdk-18.02 && make install T=x86_64-native-linuxapp-gcc DESTDIR=.

openvswitch.spec 配置更改：
# 增加dpdk的选项

%build
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=%{_localstatedir}
--libdir=%{_libdir} --enable-ssl --with-dpdk=/root/dpdk-18.02

# 修改libdir文件安装

%{_libdir}/lib*.so.*

%{_libdir}/lib*.so

这两行改成:

%{_libdir}/*

# ovs 初始化
ovs-vsctl --no-wait init
ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true
ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-socket-mem="1024,0"
ovs-vsctl --no-wait set Open_vSwitch . other_config:pmd-cpu-mask=0xf

ovs-vsctl add-br br-int -- set bridge br-int datapath_type=netdev
ovs-vsctl add-port br-int vhostuser0 -- set Interface vhostuser0 type=dpdkvhostuserclient options:vhost-server-path="/var/run/openvswitch/vhostuser0"
ovs-vsctl add-port br-int vhostuser1 -- set Interface vhostuser1 type=dpdkvhostuserclient options:vhost-server-path="/var/run/openvswitch/vhostuser1"
