虚拟化-ovn入门到精通(二)

大家好，我是小白。 继续给大家分享一下openstack和kubernetes下热门的SDN技术ovn ,今天了解一下ovn的安装部署。

ovn 安装部署

基于CentOS 7 x86_64

| 10.175.160.66 | Central | 网卡eth0/eth1 |

| 10.175.160.59 | Node1 | 网卡eth0/eth1 | vm1/vm11 |

| 10.175.160.60 | Node2 | 网卡eth0/eth1 | vm2/vm12 |

一、 系统初始化

配置repo源,ovn/ovs版本2.11.0

#vim /etc/yum.repos.d/stein.repo

[openstack-stein]

name=OpenStack Stein Repository

#baseurl=http://mirror.centos.org/centos/7/cloud/$basearch/openstack-stein/

mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=cloud-openstack-stein

gpgcheck=0

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Cloud

关闭防火墙/selinux

#systemctl stop firewalld

#systemctl disable firewalld

二、部署服务

Central 节点

# yum install -y openvswitch-ovn-central.x86_64 openvswitch-ovn-host.x86_64

#yum install libibverbs -y

# systemctl enable ovn-northd openvswitch ovn-controller

# systemctl start ovn-northd ovn-controller

Node节点

# yum install -y openvswitch.x86_64 openvswitch-ovn-host.x86_64

#yum install libibverbs -y

#systemctl enable openvswitch ovn-controller

#systemctl start ovn-controller

三、 配置OVN

配置ovs与ovn相连接

central节点

#export Centralip=10.175.160.66

#ovn-nbctl set-connection ptcp:6641:$Centralip

#ovn-sbctl set-connection ptcp:6642:$Centralip

#netstat -ntlp

#ovs-vsctl set open . external-ids:ovn-remote=tcp:$Centralip:6642

overlay网络使用geneve，当然支持geneve,vxlan,gre等

#ovs-vsctl set open . external-ids:ovn-encap-type=geneve

#ovs-vsctl set open . external-ids:ovn-encap-ip=$Centralip

node 1 节点

#export Centralip=10.175.160.66

#export NodeIP=10.175.160.59

#ovs-vsctl set open . external-ids:ovn-remote=tcp:$Centralip:6642

#ovs-vsctl set open . external-ids:ovn-encap-type=geneve

#ovs-vsctl set open . external-ids:ovn-encap-ip=$NodeIP

node2 节点

#export Centralip=10.175.160.66

#export NodeIP=10.175.160.60

#ovs-vsctl set open . external-ids:ovn-remote=tcp:$Centralip:6642

#ovs-vsctl set open . external-ids:ovn-encap-type=geneve

#ovs-vsctl set open . external-ids:ovn-encap-ip=$NodeIP

所有服务器重启一下

#reboot

至此安装完成~

排错

net_mlx5: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory

net_mlx5: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx5)

PMD: net_mlx4: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory

PMD: net_mlx4: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx4)

解决：#yum install libibverbs -y
