安装环境准备
官方部署文档：https://docs.openstack.org/kolla-ansible/train/user/quickstart.html
kolla安装节点要求：
2 network interfaces
8GB main memory
40GB disk space
本次部署train版all-in-one单节点，使用一台centos7.8 minimal节点进行部署，该节点同时作为控制节点、计算节点、网络节点和cinder存储节点使用，同时也是kolla ansible的部署节点。
kolla的安装要求目标机器至少两块网卡，本次安装使用2块网卡对应管理网络和外部网络两个网络平面，在vmware workstation虚拟机新增一块网卡ens37：
ens33，NAT模式，管理网络，正常配置静态IP即可。租户网络与该网络复用，租户vm网络不单独创建网卡
ens37，桥接模式，外部网络，无需配置IP地址，这个其实是让neutron的br-ex 绑定使用，虚拟机通过这块网卡访问外网。
网卡配置信息，大部分为默认参数
[root@kolla ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=a41355ae-f475-39d7-9e61-eb5f8f19f881
DEVICE=ens33

PREFIX=24
GATEWAY=192.168.93.2
DNS1=114.114.114.114
DNS2=8.8.8.8
IPV6_PRIVACY=no
[root@kolla ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens37
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
NAME=ens37
UUID=553a2dd0-b53e-417e-98a9-9a7a6a44a53c
DEVICE=ens37
ONBOOT=yes
如果启用cinder还需要额外添加磁盘，这里添加一块sdb盘并创建为pv和vg，使用lvm作为cinder的后端存储：
pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb
注意卷组名称为cinder-volumes，默认与后面的globals.yml中定义一致。
[root@kolla ~]# cat /etc/kolla/globals.yml | grep cinder_volume_group
#cinder_volume_group: "cinder-volumes"
部署kolla ansible
配置主机名,kolla预检查时rabbitmq可能需要能够进行主机名解析
hostnamectl set-hostname kolla
安装依赖
yum install -y python-devel libffi-devel gcc openssl-devel libselinux-python
安装 Ansible，注意版本，默认2.9应该可以满足要求
yum install -y ansible
配置阿里云pip源，否则pip安装时会很慢
mkdir ~/.pip
cat > ~/.pip/pip.conf << EOF
[global]
trusted-host=mirrors.aliyun.com
index-url=https://mirrors.aliyun.com/pypi/simple/
EOF
安装 kolla-ansible
kolla版本与openstack版本对应关系：https://releases.openstack.org/teams/kolla.html
yum install -y epel-release
yum install -y python-pip
pip install -U pip
pip install kolla-ansible==9.1.0 --ignore-installed PyYAML
复制 kolla-ansible配置文件到当前环境
mkdir -p /etc/kolla
chown $USER:$USER /etc/kolla
##Copy globals.yml and passwords.yml
cp -r /usr/share/kolla-ansible/etc_examples/kolla/* /etc/kolla
##Copy all-in-one and multinode inventory files
cp /usr/share/kolla-ansible/ansible/inventory/* .
修改ansible配置文件
$ vim /etc/ansible/ansible.cfg
[defaults]
host_key_checking=False
pipelining=True
forks=100
默认有all-in-one和multinode两个inventory文件，这里使用all-in-one，来规划集群角色，可以看到所有节点都是同一个节点kolla。
# sed -i 's#localhost ansible_connection=local#kolla#g' all-in-one
#查看修改后的配置，其他默认即可
# cat all-in-one | more
[control]
kolla
[network]
kolla
[compute]
kolla
[storage]
kolla
[monitoring]
kolla
[deployment]
kolla
...
配置主机名解析，实际在环境预配置时kolla会自动添加解析到/etc/hosts
cat >> /etc/hosts <
配置ssh免密
ssh-keygen
ssh-copy-id root@kolla
检查inventory配置是否正确，执行：
ansible -i all-in-one all -m ping
生成openstack组件用到的密码，该操作会填充/etc/kolla/passwords.yml，该文件中默认参数为空。
kolla-genpwd
如果报错执行
pip uninstall cryptography
pip install "cryptography==2.7"
修改keystone_admin_password，可以修改为自定义的密码方便后续horizon登录，这里改为kolla。
$ sed -i 's#keystone_admin_password:.*#keystone_admin_password: kolla#g' /etc/kolla/passwords.yml
$ cat /etc/kolla/passwords.yml | grep keystone_admin_password
keystone_admin_password: kolla
修改全局配置文件globals.yml，该文件用来控制安装哪些组件，以及如何配置组件，由于全部是注释，这里直接追加进去，也可以逐个找到对应项进行修改。
cp /etc/kolla/globals.yml{,.bak}
cat >> /etc/kolla/globals.yml <
参数说明：
kolla_base_distro: kolla镜像基于不同linux发型版构建，主机使用centos这里对应使用centos类型的docker镜像即可。
kolla_install_type: kolla镜像基于binary二进制和source源码两种类型构建，实际部署使用binary即可。
openstack_release: openstack版本可自定义，会从dockerhub拉取对应版本的镜像
kolla_internal_vip_address: 单节点部署kolla也会启用haproxy和keepalived，方便后续扩容为高可用集群，该地址是ens33网卡网络中的一个可用IP。
docker_registry: 默认从dockerhub拉取镜像，这里使用阿里云镜像仓库，也可以本地搭建仓库，提前推送镜像上去。但该仓库目前只有train和ussuri版本的镜像，如何自己推送镜像参考该博客的其他文章。
docker_namespace: 阿里云kolla镜像仓库所在的命名空间，dockerhub官网默认是kolla。
network_interface: 管理网络的网卡
neutron_external_interface: 外部网络的网卡
neutron_plugin_agent: 默认启用openvswitch
enable_neutron_provider_networks: 启用外部网络
enable_cinder: 启用cinder
enable_cinder_backend_lvm: 指定cinder后端存储为lvm
nova_compute_virt_type: 由于使用vmware安装，要改为qemu，否则创建虚拟机失败，生产部署默认使用kvm。
上面部分参数可能有默认配置，也可以不用明确开启，比如neutron_plugin_agent。
有些参数也可以在部署后配置，比如nova_compute_virt_type，找到配置文件修改，并重启对应组件容器即可：
[root@kolla ~]# cat /etc/kolla/nova-compute/nova.conf |grep virt_type
#virt_type = kvm
virt_type = qemu
[root@kolla ~]# docker restart nova_compute
修改docker官方yum源为阿里云yum源，另外配置docker镜像加速，指定使用阿里云镜像加速。
$ vim /usr/share/kolla-ansible/ansible/roles/baremetal/defaults/main.yaml
docker_yum_url: "https://mirrors.aliyun.com/docker-ce/linux/{{ ansible_distribution | lower }}"
docker_custom_config: {"registry-mirrors": ["https://uyah70su.mirror.aliyuncs.com"]}
部署openstack组件
部署openstack
#预配置，安装docker、docker sdk、关闭防火墙、配置时间同步等
kolla-ansible -i ./all-in-one bootstrap-servers
#部署前环境检查
kolla-ansible -i ./all-in-one prechecks
#拉取镜像，也可省略该步骤，默认会自动拉取
kolla-ansible -i ./all-in-one pull
#执行实际部署，拉取镜像，运行对应组件容器
kolla-ansible -i ./all-in-one deploy
报错
1、no test named 'equalto'
pip install -U Jinja2
pip install Jinja2===2.10.2 (成功)
2、另外关闭systemctl stop NetworkManager
3、计算节点安装neutron组件时验证sysctl值的时候报错
sysctl net.bridge.bridge-nf-call-ip6tables
sysctl net.bridge.bridge-nf-call-iptables
报错sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
用以下命令解决
[root@computer ~]# modprobe br_netfilter
[root@computer ~]# ls /proc/sys/net/bridge/
bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-filter-vlan-tagged
bridge-nf-call-ip6tables bridge-nf-filter-pppoe-tagged bridge-nf-pass-vlan-input-dev
[root@computer ~]# sysctl -p
[root@computer ~]# sysctl net.bridge.bridge-nf-call-ip6tables
net.bridge.bridge-nf-call-ip6tables = 1
[root@computer ~]# sysctl net.bridge.bridge-nf-call-iptables
net.bridge.bridge-nf-call-iptables = 1
以上部署没有报错中断说明部署成功，所有openstack组件以容器方式运行，查看容器
[root@kolla ~]# docker ps -a

另外需要注意，不要在该节点安装libvirt等工具，这些工具安装后可能会启用libvirtd和iscsid.sock等服务，kolla已经在容器中运行了这些服务，这些服务会调用节点上的sock文件，如果节点上也启用这些服务去抢占这些文件，会导致容器异常。默认kolla在预配置时也会主动禁用节点上的相关服务。
安装OpenStack客户端
执行openstack相关命令和操作，需要本地安装openstack客户端，但是本次在kolla节点安装客户端报错，所以直接启动一个官方的base容器，该容器默认带有客户端命令，使用时将admin-openrc.sh挂载进容器即可。
安装OpenStack CLI客户端(可能报错，略过该步骤)
pip install python-openstackclient
kolla-ansible post-deploy
cat /etc/kolla/admin-openrc.sh
kolla ansible提供了一个快速创建cirros demo实例的脚本(可能报错，略过该步骤)
source /etc/kolla/admin-openrc.sh
/usr/share/kolla-ansible/init-runonce
访问openstack horizon
访问openstack horizon需要使用vip地址，节点上可以看到由keepalived容器生成的vip
[root@kolla ~]# ip a |grep ens33
2: ens33: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
inet 192.168.93.30/24 brd 192.168.93.255 scope global ens33
inet 192.168.93.100/32 scope global ens33
浏览器直接访问该地址即可登录到horizon
http://192.168.93.100
我这里的用户名密码为admin/kolla，信息可以从admin-openrc.sh中获取
[root@kolla ~]# cat /etc/kolla/admin-openrc.sh
# Clear any old environment that may conflict.
for key in $( set | awk '{FS="="} /^OS_/ {print $1}' ); do unset $key ; done
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=kolla
export OS_AUTH_URL=http://192.168.93.100:35357/v3
export OS_INTERFACE=internal
export OS_ENDPOINT_TYPE=internalURL
export OS_IDENTITY_API_VERSION=3
export OS_REGION_NAME=RegionOne
export OS_AUTH_PLUGIN=password
容器运行openstack客户端
由于在kolla主机节点没有成功安装openstack客户端，这里在容器里使用客户端
拉取官方镜像地址是kolla/centos-binary-openstack-base:train，这里从阿里云拉取
docker pull registry.cn-shenzhen.aliyuncs.com/kollaimage/centos-binary-openstack-base:train
进入容器就可以正常执行openstack相关命令了
[root@kolla ~]# docker exec -it client bash
()[root@f11a103c5ade /]# source /admin-openrc.sh
()[root@f11a103c5ade /]# openstack service list

示例demo脚本也被挂载到了容器，修改init-runonce示例脚本外部网络部分的配置，然后执行该shell脚本
()[root@f11a103c5ade /]# cat init-runonce
# This EXT_NET_CIDR is your public network,that you want to connect to the internet via.
ENABLE_EXT_NET=${ENABLE_EXT_NET:-1}
EXT_NET_CIDR=${EXT_NET_CIDR:-'192.168.1.0/24'}
EXT_NET_RANGE=${EXT_NET_RANGE:-'start=192.168.1.200,end=192.168.1.250'}
EXT_NET_GATEWAY=${EXT_NET_GATEWAY:-'192.168.1.1'}
$ bash init-runonce
参数说明：
EXT_NET_CIDR 指定外部网络，由于使用桥接模式，直接桥接到了电脑的无线网卡，所以这里网络就是无线网卡的网段。
EXT_NET_RANGE 指定从外部网络取出一个地址范围，作为外部网络的地址池
EXT_NET_GATEWAY 外部网络网关，这里与wifi网络使用的网关一致
脚本会创建一些资源，如下载cirros镜像并上传，创建外部和内部网络等，另外脚本执行过程中会创建ssh key，直接回车即可，默认保存在容器中的/root/.ssh目录下，其中的id_rsa私钥可以用来远程连接实例使用。
该脚本首先会从github下载cirros镜像，如果网络较慢可以提前下载到cache目录
docker exec -it client mkdir -p /opt/cache/files/
wget https://github.com/cirros-dev/cirros/releases/download/0.4.0/cirros-0.4.0-x86_64-disk.img
docker cp cirros-0.4.0-x86_64-disk.img client:/opt/cache/files/
最后根据提示手动运行一个实例
openstack server create \
--image cirros \
--flavor m1.tiny \
--key-name mykey \
--network demo-net \
demo1
在horizion查看创建的网络和实例
登录实例控制台，验证实例与外网的连通性，cirros用户密码在初次登录时有提示：
在kolla节点上ssh连接实例浮动IP，cirros镜像默认用户密码为cirros/gocubsgo，该镜像信息官网有介绍：https://docs.openstack.org/image-guide/obtain-images.html#cirros-test
[root@kolla ~]# ssh [email protected]
[email protected]'s password:
$
$
运行CentOS实例
centos官方维护有相关cloud image，如果不需要进行定制，可以直接下载来运行实例。参考：https://docs.openstack.org/image-guide/obtain-images.html
CentOS官方维护的镜像下载地址：http://cloud.centos.org/centos/7/images/
也可以使用命令直接下载镜像，但是下载可能较慢，建议下载好在进行上传。以centos7.8为例：
wget http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-2003.qcow2c
下载完成后上传镜像到openstack，直接在horizon上传即可。也可以使用命令上传。
注意：默认该镜像运行的实例只能使用ssh key以centos用户身份登录，如果需要使用root远程ssh连接到实例需要在上传前为镜像配置root免密并开启ssh访问。
参考：https://blog.csdn.net/networken/article/details/106713658
另外我们的命令客户端在容器中，所有这里有些不方便，首先要将镜像复制到容器中，然后使用openstack命令上传。
这里复制到client容器的根目录下。
[root@kolla ~]# docker cp CentOS-7-x86_64-GenericCloud-2003.qcow2c client:/
[root@kolla ~]# docker exec -it client bash
()[root@f11a103c5ade /]#
()[root@f11a103c5ade /]# source /admin-openrc.sh
()[root@f11a103c5ade /]# ls | grep CentOS
CentOS-7-x86_64-GenericCloud-2003.qcow2c
执行以下openstack命令上传镜像
openstack image create "CentOS78-image" \
--file CentOS-7-x86_64-GenericCloud-2003.qcow2c \
--disk-format qcow2 --container-format bare \
--public
如果实例创建失败可以查看相关组件报错日志
[root@kolla ~]# tail -100f /var/log/kolla/nova/nova-compute.log
未配置root密码连接实例
如果没有提前定制镜像修改root密码，只能使用centos用户及sshkey登录，由于是在容器中运行的demo示例，ssh私钥也保存在容器的默认目录下，在容器中连接实例浮动IP测试
[root@kolla ~]# docker exec -it client bash
()[root@f11a103c5ade /]# ssh -i /root/.ssh/id_rsa [email protected]

[centos@centos78 ~]$
运行Ubuntu实例
下载镜像
wget https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img
上传镜像
openstack image create "Ubuntu1804" \
--file bionic-server-cloudimg-amd64.img \
--disk-format qcow2 --container-format bare \
--public
按照正常流程创建实例即可，ubuntu镜像默认用户为ubuntu，首次登陆使用sshkey方式，然后执行以下命令即可直接切换到root用户(centos无法使用该方式)
$ sudo -i
