CentOS7安装ovs

Step1:安装依赖

[root@VSW2 ~]# yum install gcc pkgconfig autoconf automake libtool git make python-devel openssl-devel kernel-devel kernel-debug-devel

Step2:下载源码

[root@VSW2 ~]# wget http://openvswitch.org/releases/openvswitch-2.8.1.tar.gz

[root@VSW2 ~]# tar zxvf openvswitch-2.8.1.tar.gz

Step3:编译安装

[root@VSW2 ~]# cd openvswitch-2.8.1

[root@VSW2 openvswitch-2.8.1]# ./configure --prefix=/usr/local/ovs

依赖处理：

configure: WARNING: cannot find libcap-ng.
--user option will not be supported on Linux.
(you may use --disable-libcapng to suppress this warning).
checking for Python 2.x for x >= 7... /usr/bin/python
checking whether /usr/bin/python has six library... configure: error: Missing Python six library or version too old.

解决方法：

[root@VSW2 openvswitch-2.8.1]# yum install python-six.noarch -y

[root@VSW2 openvswitch-2.8.1]# make -j 4

[root@VSW2 openvswitch-2.8.1]# make install

Step4:加载模块

[root@VSW2 openvswitch-2.8.1]# modprobe openvswitch

[root@VSW2 openvswitch-2.8.1]# lsmod | grep openvswitch
openvswitch 114793 0
nf_nat_ipv6 14131 1 openvswitch
nf_nat_ipv4 14115 1 openvswitch
nf_defrag_ipv6 35104 2 openvswitch,nf_conntrack_ipv6
nf_nat 26787 3 openvswitch,nf_nat_ipv4,nf_nat_ipv6
nf_conntrack 133095 6 openvswitch,nf_nat,nf_nat_ipv4,nf_nat_ipv6,nf_conntrack_ipv4,nf_conntrack_ipv6
libcrc32c 12644 4 xfs,openvswitch,nf_nat,nf_conntrack
[root@VSW2 openvswitch-2.8.1]#

Step5:修改环境变量

[root@VSW2 openvswitch-2.8.1]# vim /etc/profile

最后一行追加：

export PATH=/usr/local/ovs/share/openvswitch/scripts:/usr/local/ovs/bin:/usr/local/ovs/sbin:$PATH

[root@VSW2 openvswitch-2.8.1]# source /etc/profile
