1, virt-manager中创建一个名为cloud的network(192.168.100.0/24), 禁用dhcp

2, 创建一台1 CPU, 4G MEM, 20G raw DISK的KVM虚机(ubuntu/password)．
　　两块网卡，一块(enp1s0)使用默认的default network当管理用(其实不能，因为环境建好后这个网卡会失去ssh连接）, 一块(enp6s0)使用cloud network（从这块网络ssh进入即可，如果不能访问外网记得删除enp1s0上的默认路由）. 
   虚机启动后为cloud网卡配置下列IP:
cat <<EOF | sudo tee /etc/netplan/90-local.yaml
network:
  version: 2
  ethernets:
    enp6s0:
      dhcp4: no
      addresses:
      - 192.168.100.122/24
      gateway4: 192.168.15$i.1
      nameservers:
        addresses:
        - 192.168.100.1
EOF
sudo netplan apply
ubuntu@o7k:~$ cat /etc/netplan/01-netcfg.yaml 
network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: yes

然后通过'ssh ubuntu@192.168.100.122'进入虚机，别用enp1s0因为它在完成部署后可以失去网络连接（被配置成了混杂模式）

3, 虚机的其他设置：
echo 'precedence ::ffff:0:0/96 100' |sudo tee -a /etc/gai.conf
echo 'ubuntu     ALL=(ALL) NOPASSWD:ALL' |sudo tee -a /etc/sudoers
cat <<EOF | sudo tee -a /etc/hosts
# and need to remove '127.0.1.1       o7k' as well
192.168.100.122 o7k
EOF

4, 特色网络配置
sudo cp /etc/apt/sources.list /etc/apt/sources.list_bak
sudo sed -i s/us.archive.ubuntu.com/mirrors.tuna.tsinghua.edu.cn/g /etc/apt/sources.list
sudo apt clean
sudo apt update
sudo apt upgrade -y
sudo apt install apt-transport-https ca-certificates curl gnupg2 software-properties-common -y
sudo apt install python3-dev libffi-dev gcc libssl-dev -y

sudo apt install python3-pip -y && sudo pip3 install --upgrade pip
#http://mirrors.cloud.tencent.com/pypi/simple
#http://pypi.douban.com/simple/
mkdir -p ~/.pip
cat <<EOF | sudo tee ~/.pip/pip.conf
[global]
index-url=https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host=pypi.tuna.tsinghua.edu.cn
EOF
pip3 config list

5, 安装docker

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository \\
   "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update -y
sudo apt-get install docker-ce docker-ce-cli containerd.io -y
sudo systemctl enable docker && sudo systemctl start docker && sudo systemctl status docker
#https://registry.docker-cn.com
cat << EOF | sudo tee /etc/docker/daemon.json
{
"registry-mirrors":["https://3wk75oh9.mirror.aliyuncs.com"]                 
}
EOF
sudo systemctl daemon-reload && sudo systemctl restart docker
#sudo docker run -d --name pause busybox:latest /bin/sleep 10000000
sudo pip3 install docker

6, 安装并配置ansible
#git clone https://github.com/openstack/kolla-ansible -b stable/rocky
#pip install -r kolla-ansible/requirements.txt
sudo pip3 install -U 'ansible<2.9.19'

EOF

7, 运行ansible
ansible -i all-in-one all -m ping
sudo pip3 install docker
kolla-ansible -i ./all-in-one prechecks -vv
#kolla-ansible -i ./all-in-one destroy --yes-i-really-really-mean-it && sudo netplan apply
kolla-ansible -i ./all-in-one bootstrap-servers -vv #install dependenty
kolla-ansible -i ./all-in-one deploy -vv

注意：此时外部网卡会失去连接（当然，我们是通过内部网卡ssh ubuntu@192.168.101.122连接的)
想上网的话：
sudo route del default gw 192.168.101.1
sudo route add default gw 192.168.100.1

8, 运行OpenStack CLI

sudo add-apt-repository cloud-archive:victoria
sudo apt update && apt dist-upgrade
sudo apt install python3-openstackclient -y

kolla-ansible -i all-in-one post-deploy
cp /etc/kolla/admin-openrc.sh ./
chmod +x admin-openrc.sh
source ~/admin-openrc.sh

# enp1s0=192.168.101.201 enp6s0=192.168.100.122

EXT_NET_GATEWAY=${EXT_NET_GATEWAY:-'192.168.101.1'}

. /usr/local/share/kolla-ansible/init-runonce
# visit http://192.168.100.123 admin password

#CLI
ssh-keygen -q -N ""
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
openstack flavor create --ram 512 --disk 1 --vcpu 1 --id 122 myflavor
cat << EOF > user-data
#cloud-config

chpasswd: { expire: False }
EOF
openstack server create --wait --image cirros --flavor myflavor --key-name mykey --network=demo-net --user-data ./user-data --config-drive true i1

# Don't know why there is no subnet for the network public1, so create it
openstack subnet create --subnet-range 192.168.101.0/24 --network public1 --allocation-pool start=192.168.101.87,end=192.168.101.200 --gateway 192.168.101.1 public1-subnet
#openstack router unset demo-router
openstack router set --external-gateway public1 demo-router
#openstack router remove subnet demo-router demo-subnet
openstack router add subnet demo-router demo-subnet

fix_ip=$(openstack server list -f value |awk '/i1/ {print $4}' |awk -F '=' '{print $2}' |awk -F ',' '{print $1}')
ext_net=$(openstack network show public1 -f value -c id)
fip=$(openstack floating ip create $ext_net -f value -c floating_ip_address)
openstack floating ip set $fip --fixed-ip-address $fix_ip --port $(openstack port list --fixed-ip ip-address=$fix_ip -c id -f value)

SG=$(openstack security group list --project $(openstack project show admin -fvalue -cid) |awk '/default/ {print $2}')
openstack security group rule create $SG --protocol icmp --remote-ip 0.0.0.0/0
openstack security group rule create $SG --protocol tcp --dst-port 22

openstack console log show i1
#login as 'cirros' user. default password: 'gocubsgo'. use 'sudo' for root.

ubuntu@o7k:~$ nova list
+--------------------------------------+------+--------+------------+-------------+--------------------------------------+
| ID                                   | Name | Status | Task State | Power State | Networks                             |

8, 结果，只是在o7k虚机上无法访问里面虚机i1的FIP，但这个FIP可以在其他机器访问的．正确
sudo docker ps |grep neutron
sudo docker exec -ti -uroot neutron_l3_agent bash
(neutron-l3-agent)[root@o7k /]# ip netns exec qrouter-38ba43f7-d3d7-4770-890d-06a9b1845e89 ping 10.0.0.154
