大家好，我是小白。 繼續(xù)給大家分享一下openstack和kubernetes下熱門的SDN技術(shù)ovn ,今天了解一下ovn的安裝部署。
ovn 安裝部署
基于CentOS 7 x86_64
| 10.175.160.66 | Central | 網(wǎng)卡eth0/eth1 |
| 10.175.160.59 | Node1 | 網(wǎng)卡eth0/eth1 | vm1/vm11 |
| 10.175.160.60 | Node2 | 網(wǎng)卡eth0/eth1 | vm2/vm12 |
一、 系統(tǒng)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
關(guān)閉防火墻/selinux
#systemctl stop firewalld
#systemctl disable firewalld
二、部署服務(wù)
Central 節(jié)點(diǎn)
# 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節(jié)點(diǎn)
# 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與ovn相連接
central節(jié)點(diǎn)
#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:$Centralip:6642
overlay網(wǎng)絡(luò)使用geneve，當(dāng)然支持geneve,vxlan,gre等
#ovs-vsctl set open . external-ids:ovn-encap-type=geneve
#ovs-vsctl set open . external-ids:ovn-encap-ip=$Centralip
node 1 節(jié)點(diǎn)
#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 節(jié)點(diǎn)
#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
所有服務(wù)器重啟一下
#reboot
至此安裝完成~
排錯(cuò)
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)
解決：#yum install libibverbs -y
