yum install epel-release -y
wget --no-check-certificate https://www.openvswitch.org/releases/openvswitch-2.11.1.tar.gz
# 生成rpmbuild目录
rpmbuild -bb --nocheck /root/rpmbuild/SOURCES/openvswitch-2.11.1/rhel/openvswitch-fedora.spec
# 移动并解压openvswitch包打指定目录
mv /root/openvswitch-2.11.1.tar.gz /root/rpmbuild/SOURCES/
tar xf /root/rpmbuild/SOURCES/openvswitch-2.11.1.tar.gz -C /root/rpmbuild/SOURCES/
# 显示openvswitch需要的依赖包
rpmbuild -bb --nocheck /root/rpmbuild/SOURCES/openvswitch-2.11.1/rhel/openvswitch-fedora.spec
# 安装依赖包
yum install -y openssl-devel python-devel desktop-file-utils groff graphviz checkpolicy selinux-policy-devel python-sphinx python-twisted-core python-zope-interface libcap-ng-devel unbound unbound-devel
# 生成rpm安装包
rpmbuild -bb --nocheck /root/rpmbuild/SOURCES/openvswitch-2.11.1/rhel/openvswitch-fedora.spec
# 安装openvswitch
yum localinstall /root/rpmbuild/RPMS/x86_64/openvswitch-2.11.1-1.el7.x86_64.rpm
# 启用openvswitch服务
service openvswitch start|systemctl start openvswitch
systemctl status openvswitch
systemctl enable openvswitch
# 查看openvswitch版本
ovs-vsctl -V

Open Vswitch常用命令

# 查询vswitch中有哪些数据库
ovsdb-client list-dbs
# 查询Open_vSwitch库中的有哪些表
ovsdb-client list-tables Open_vSwitch
# 查询Interface表中有哪些字段
ovsdb-client list-columns Interface
# 获取Interface表中的全部数据
ovsdb-client dump Interface
# 查看openvswitch配置
ovs-vsctl list Open_vSwitch .
# 修改openvswitch配置
ovs-vsctl set Open_vSwitch . other_config:flow-limit=1000000
ovs-vsctl set Open_vSwitch . other_config:emc-insert-inv-prob=1
ovs-vsctl set Open_vswitch . other_config:n-handler-threads=4
ovs-vsctl set Open_vSwitch . other_config:n-revalidator-threads=4
ovs-vsctl set Open_vSwitch . other_config:max-idle=30000
# 删除ovs相关配置
ovs-vsctl remove Open_vSwitch . other_config flow-limit
ovs-vsctl remove Open_vSwitch . other_config emc-insert-inv-prob
ovs-vsctl remove Open_vSwitch . other_config n-handler-threads
ovs-vsctl remove Open_vSwitch . other_config n-revalidator-threads
ovs-vsctl remove Open_vSwitch . other_config max-idle
# 查看所有接口
ovs-vsctl list interface
# 查看eth1口的详细信息
ovs-vsctl list interface eth1
# json格式输出eth1接口信息
ovs-vsctl --format=json list interface eth1     # 输出格式有：table、html、csv、json
# 输出pod在node节点上的接口名称(-B 1表示输出匹配行之前的一行，-A 1表示输出匹配行后面的一行)
ovs-vsctl list interface | grep -Ew "name|external_ids" | grep -A 1 [podname]
ovs-vsctl --columns=name,mac_in_use,external_ids,ifindex --format=table list interface | grep busybox
# 查看桥br-int上的所有流规则
ovs-ofctl dump-flows br-int
ovs-appctl dpctl/dump-flows system@ovs-system
ovs-appctl bridge/dump-flows br-int
# 过滤所有入站到指定端口的流规则
ovs-ofctl dump-flows br-int in_port=<port-number>
# 按优先级或目的IP降序排列流表
ovs-ofctl dump-flows br-int table=4 --rsort=priority/nw_dst
# 按优先级或目的IP升序排列流表
ovs-ofctl dump-flows br-int table=4 --sort=priority/nw_dst
# 过滤桥br-int中符合table=4,协议为ip，目的ip为10.147.6.26的流表
ovs-ofctl dump-flows br-int table=4,ip,nw_dst=10.147.6.26 --sort
# 查看桥br-int中符合table=2且in_port=probe的所有流
ovs-ofctl dump-flows br-int table=2,in_port=probe --sort
# 过滤桥br-int中符合table=2,协议为tcp，目的ip为10.233.0.3的流表
ovs-ofctl dump-flows br-int table=2,tcp,nw_dst=10.233.0.3 --sort
