如何在CentOS 8| rhel 8上安装Open vswitch
时间：2020-02-23 14:38:42 来源:igfitidea点击:
Open VSwitch是一个创建的多层软件交换机，提供一个开源，支持标准管理接口的生产质量开关平台，并打开转发功能，以便对编程扩展和控制。
开放式vswitch广泛用作虚拟机环境中的虚拟交换机，如OpenStack实现。
在本文中，我们将在CentOS 8| rhel 8上安装Open vswitch
在CentOS 8/Rhel 8上安装Open Vswitch
我们将使用OpenStack存储库来拉开VSwitch RPM包。
将OpenStack存储库添加到CentOS 8
sudo yum install -y epel-release sudo yum install -y centos-release-openstack-train
将OpenStack存储库添加到Rhel 8
对于RHEL 8，如果我们有活动订阅，我们可以使用Red Hat OpenStack 16存储库：
sudo subscription-manager repos --enable=openstack-16-for-rhel-8-x86_64-rpms sudo subscription-manager repos --enable=fast-datapath-for-rhel-8-x86_64-rpms sudo subscription-manager repos --enable=rhel-8-server-optional-rpms
如果我们没有Red Hat OpenStack订阅，请使用RDO：
sudo subscription-manager repos --enable=rhel-8-server-optional-rpms sudo sudo yum install https://rdoproject.org/repos/rdo-release.rpm
然后在CentOS 8上安装Open VSwitch | RHEL 8：
sudo yum install openvswitch libibverbs
接受安装：

启动并启用OpenVSwitch服务：
sudo systemctl enable --now openvswitch
确认服务状态：
$systemctl status openvswitch ● openvswitch.service - Open vSwitch Loaded: loaded (/usr/lib/systemd/system/openvswitch.service; enabled; vendor preset: disabled) Active: active (exited) since Fri 2017-06-05 23:24:15 CEST; 24s ago Process: 9704 ExecStart=/bin/true (code=exited, status=0/SUCCESS) Main PID: 9704 (code=exited, status=0/SUCCESS) Jun 05 23:24:15 centos.theitroad.com systemd[1]: Starting Open vSwitch... Jun 05 23:24:15 centos.theitroad.com systemd[1]: Started Open vSwitch.
检查OVS-VSCTL命令是否可用。
# ovs-vsctl show

ovs_version: "2.12.0"
如果我们计划使用它配置Open vswitch，可选择安装OS-Net-Config。
sudo yum install os-net-config
