openstack O版 配置compute节点 nova 和 Neutron安装
更新:HHH   时间:2023-1-7


  1. 配置nova.conf
    [root@compute ~]# yum install openstack-selinux python-openstackclient yum-plugin-priorities openstack-nova-compute openstack-utils ntpdate -y
    [root@compute ~]# cp /etc/nova/nova.conf /etc/nova/nova.conf.bak
    [root@compute ~]# >/etc/nova/nova.conf
    [DEFAULT]
    auth_strategy = keystone
    my_ip = 192.168.0.112
    use_neutron = True
    firewall_driver = nova.virt.firewall.NoopFirewallDriver
    transport_url = rabbit://openstack:devops@controller
    [keystone_authtoken]
    auth_uri = http://controller:5000
    auth_url = http://controller:35357
    memcached_servers = controller:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = nova
    password = devops
    [placement]
    auth_uri = http://controller:5000
    auth_url = http://controller:35357
    memcached_servers = controller:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = placement
    password = devops
    os_region_name = RegionOne
    [vnc]
    enabled = True
    keymap = en-us
    vncserver_listen = 0.0.0.0
    vncserver_proxyclient_address = 192.168.0.112
    novncproxy_base_url = http://192.168.0.111:6080/vnc_auto.html
    [glance]
    api_servers = http://controller:9292
    [oslo_concurrency]
    lock_path = /var/lib/nova/tmp
    [libvirt]
    virt_type = qemu
  2. 设置libvirtd.service 和openstack-nova-compute.service开机启动
    [root@compute ~]# systemctl enable libvirtd.service openstack-nova-compute.service
    [root@compute ~]# systemctl restart libvirtd.service openstack-nova-compute.service
    [root@compute ~]# systemctl status libvirtd.service openstack-nova-compute.service
  3. 到controller上执行验证
    [root@controller ~]# source admin-openrc
    [root@controller ~]# openstack compute service list

    二、安装Neutron
  4. 安装相关软件包
    [root@compute ~]# yum install openstack-neutron-linuxbridge ebtables ipset -y
    [root@compute ~]# cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak
    [root@compute ~]# >/etc/neutron/neutron.conf
    [DEFAULT]
    auth_strategy = keystone
    advertise_mtu = True
    dhcp_agents_per_network = 2
    control_exchange = neutron
    nova_url = http://controller:8774/v2
    transport_url = rabbit://openstack:devops@controller
    [keystone_authtoken]
    auth_uri = http://controller:5000
    auth_url = http://controller:35357
    memcached_servers = controller:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = neutron
    password = devops
    [oslo_concurrency]
    lock_path = /var/lib/neutron/tmp
  5. 配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini
    [root@compute ~]# cat /etc/neutron/plugins/ml2/linuxbridge_agent.ini | grep -v "^#" | grep -v "^$"
    [DEFAULT]
    [agent]
    [linux_bridge]
    physical_interface_mappings = provider:ens33
    [securitygroup]
    enable_security_group = True
    firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
    [vxlan]
    enable_vxlan = True
    local_ip = 192.168.0.112
    l2_population = True
  6. 配置nova.conf
    [neutron]
    url = http://controller:9696
    auth_url = http://controller:35357
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    region_name = RegionOne
    project_name = service
    username = nova
    password = devops
  7. 重启和enable相关服务
    [root@compute ~]# systemctl restart libvirtd.service openstack-nova-compute.service
    [root@compute ~]# systemctl enable neutron-linuxbridge-agent.service
    [root@compute ~]# systemctl restart neutron-linuxbridge-agent.service
    [root@compute ~]# systemctl status libvirtd.service openstack-nova-compute.service neutron-linuxbridge-agent.service
    三.在controler上执行验证
    [root@controller ~]# source admin-openrc
    [root@controller ~]# neutron agent-list

    [root@controller ~]# nova host-list
