openstack架構部署Centos7虛擬機

前期準備

部署openstack可參考:http://www.javashuo.com/article/p-dszayery-mn.html
配置虛擬機設置

導入環境變量

[root@controller ~]# vi admin-openrc 
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

[root@controller ~]# source admin-openrc

配置可修改root密碼

controller配置

[root@controller ~]# vi /etc/openstack-dashboard/local_settings 
OPENSTACK_HYPERVISOR_FEATURES = {
    'can_set_mount_point': False,
    'can_set_password': True,
    'requires_keypair': False,
}

#重啓服務
[root@controller ~]# systemctl restart httpd.service memcached.service

computer配置

[root@computer ~]# vi /etc/nova/nova.conf
[libvirt]
inject_password = true
inject_partition = -1

#重啓服務
[root@computer ~]# systemctl stop libvirtd.service  openstack-nova-compute.service 
[root@computer ~]# systemctl start libvirtd.service  openstack-nova-compute.service

下載鏡像包

下載CentOS-7-x86_64-GenericCloud-1907.qcow2鏡像包
下載地址:https://cloud.centos.org/centos/7/images/

鏡像包上傳到openstack

[root@controller ~]# openstack image create "Centos7" --file CentOS-7-x86_64-GenericCloud-1907.qcow2 --disk-format qcow2 --container-format bare --public

建立flavor

建立密鑰

[root@controller ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

建立安全組規則

建立網絡

建立provicer網絡

[root@controller ~]# openstack network create  --share --external  --provider-physical-network provider  --provider-network-type flat provider

設置子網

[root@controller ~]# openstack subnet create --network provider --allocation-pool start=192.168.31.100,end=192.168.31.120 --gateway 192.168.31.1 --subnet-range 192.168.31.0/24 provider

建立self-service網絡

[root@controller ~]# openstack network create selfservice

建立子網

[root@controller ~]# openstack subnet create --network selfservice --gateway 172.16.1.1  --subnet-range 172.16.1.0/24 selfservice

建立並配置路由

[root@controller ~]# openstack router create router

[root@controller ~]# neutron router-interface-add router selfservice
[root@controller ~]# neutron router-gateway-set router provider

建立實例

設置root密碼

綁定浮動IP

測試驗證

[root@controller ~]# ping -c 5 192.168.31.101
