编译 OpenvSwitch RPM 包

本博客主要介绍如何在CentOS6.5上编译OpenvSwitch RPM包。

基于CentOS 7编译 ovs2.12.x/2.13.x

依赖处理：

yum -y install epel-release \
    && yum -y install @'Development Tools' rpm-build yum-utils rpmdevtools \
    sudo mock patch make vim install openssl openssl-devel python3 python3-devel python3-sphinx \
    desktop-file-utils groff graphviz checkpolicy selinux-policy-devel \
    libcap-ng-devel libpcap-devel numactl-devel dpdk-devel \
    unbound unbound-devel python3-sphinx libibverbs libmnl-devel \
    python-sphinx python-twisted-core python-zope-interface python-six \
    && cd /usr/lib64 \
    && ln -s ./libmlx4.so.1.0.22.4 libmlx4.so \
    && ln -s ./libmlx5.so.1.8.22.4 libmlx5.so \
    && cd /usr/lib64 \
    && ln -s ./libibverbs.so.1.5.22.4 libibverbs.so

• build rpms

tar xf openvswitch-2.12.3.tar.gz
cd openvswitch-2.12.3
./boot.sh
./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc
make rpm-fedora RPMBUILD_OPT="--with dpdk --without check"

安装依赖包

yum install -y rpmdevtools rpm-build kernel-headers kernel-devel gcc make python-devel openssl-devel kernel-devel graphviz kernel-debug-devel automake autoconf redhat-rpm-config libtool git

下载ovs

下载的版本为：openvswitch-2.3.2.tar.gz

wget http://openvswitch.org/releases/openvswitch-2.3.2.tar.gz -O openvswitch-2.3.2.tar.gz

编译

关于 spec 文件，可以参考：https://github.com/rdo-common/openvswitch，也可以采用 openvswitch tar包中的文件。

[root@xiexianbin_cn ~]# rpmdev-setuptree
[root@xiexianbin_cn ~]# cp /root/openvswitch-2.3.2.tar.gz /root/rpmbuild/SOURCES/
[root@xiexianbin_cn ~]# tar -zxf openvswitch-2.3.2.tar.gz
[root@xiexianbin_cn ~]# cd openvswitch-2.3.2
[root@xiexianbin_cn ~]# rpmbuild -bb --without check rhel/openvswitch.spec
[root@xiexianbin_cn openvswitch-2.3.2]# rpmbuild -bb --without check rhel/openvswitch-kmod-rhel6.spec
[root@xiexianbin_cn openvswitch-2.3.2]# cp rhel/openvswitch-kmod.files /root/rpmbuild/SOURCES/
[root@xiexianbin_cn openvswitch-2.3.2]# rpmbuild -bb -D "kversion 2.6.32-431.23.3.el6.x86_64" -D "kflavors default" rhel/openvswitch-kmod-rhel6.spec

注释：

1. kversion 内核版本可通过uname -r

编译结果：

[root@xiexianbin_cn x86_64]# cd /root/rpmbuild/RPMS/x86_64
[root@xiexianbin_cn x86_64]# ll
