小编给大家分享一下如何使用Kolla-Ansible在CentOS 7单节点上部署OpenStack Pike，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
虽然是进行单节点部署，但只要修改主机清单文件，在其他配置基本不变的情况下，也可以多节点部署。
这里使用了两个网卡，除了Neutron的虚拟网络在eth2上以外，其他的所有服务均放在eth0上。
由于eth2被Neutron放在了qrouter-XXX的网络NameSpace中，所以宿主机无法直接通过eth2进行通信。
要想使用eth2的网络，必须使用“ip netns exec qrouter-XXX”命令执行相关命令，或者建立一个网桥并绑定eth2和一个虚拟网卡，把虚拟网卡给Neutron使用，宿主机通过网桥使用eth2。
由于只有一个节点，所以禁用了"HAProxy"服务，并把所有VIP都设置为eth0的IP。
在VMware14中安装CentOS 7 X64 1708发行版，最好是重新安装一个精简干净的系统；
系统内存4G，空闲硬盘空间30G，内核版本为“3.10.0-693.11.6.el7.x86_64”；
有两个网卡，eth0为“192.168.195.170”,eth2为“192.168.162.170”；
修改“/etc/hosts”，在其中增加“192.168.195.170 controller”。
官方对安装Pike版本相关的软件包版本要求如下：
Component Min Version Max Version Comment Ansible 2.2.0 none On deployment host Docker 1.10.0 none On target nodes Docker Python 2.0.0 none On target nodes Python Jinja2 2.8.0 none On deployment host
启动NTP服务：
$ systemctl enable ntpd.service && systemctl start ntpd.service && systemctl status ntpd.service
关闭libvirtd服务：
$ systemctl stop libvirtd.service && systemctl disable libvirtd.service && systemctl status libvirtd.service
关闭防火墙：
$ systemctl stop firewalld && systemctl disable firewalld && systemctl status firewalld
如果有的话，卸载旧的Docker，否则可能会不兼容：
$ yum remove -y docker docker-io docker-selinux python-docker-py
新增Docker的Yum仓库：
$ vi /etc/yum.repos.d/docker.repo [dockerrepo] name=Docker Repository baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/ enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg
安装Docker软件包：
$ yum update $ yum install -y epel-release $ yum install -y docker-engine docker-engine-selinux
使用阿里的Docker镜像服务（也可以自己去申请一个地址）：
$ mkdir -p /etc/docker
$ vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://7g5a4z30.mirror.aliyuncs.com"]
}重启Docker服务：
$ systemctl daemon-reload && systemctl enable docker && systemctl restart docker && systemctl status docker
检查镜像服务是否正常：
$ docker run --rm hello-world Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://cloud.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/
运行Register容器，映射到4000端口：
$ docker run -d --name registry --restart=always -p 4000:5000 -v /opt/registry:/var/lib/registry registry:2
修改Docker服务配置，信任本地Registry服务：
$ vi /usr/lib/systemd/system/docker.service ... #ExecStart=/usr/bin/dockerd ExecStart=/usr/bin/dockerd --insecure-registry controller:4000 ...
重启Docker服务：
$ systemctl daemon-reload && systemctl restart docker
测试Registry服务是否正常：
$ curl -X GET http://controller:4000/v2/_catalog
{"repositories":[]}配置Docker共享挂载：
$ mkdir -pv /etc/systemd/system/docker.service.d $ vi /etc/systemd/system/docker.service.d/kolla.conf [Service] MountFlags=shared
重启Docker服务：
$ systemctl daemon-reload && systemctl restart docker && systemctl status docker
下载OpenStack Pike的Docker镜像：
$ wget http://tarballs.openstack.org/kolla/images/centos-source-registry-pike.tar.gz
解压OpenStack Pike的Docker镜像：
$ tar zxvf centos-source-registry-pike.tar.gz -C /opt/registry/
检查Docker镜像是否已经加入到Registry服务中（如果不能看到如下信息，则重启Registry容器）：
$ curl -X GET http://controller:4000/v2/_catalog

$ docker restart registry
安装依赖的软件包：
$ yum install -y python-devel python-pip libffi-devel gcc openssl-devel git
如果后面出现urllib3错误，则把下面的命令执行两次（出现的命令行交互中选择“y”）：
$ pip uninstall urllib3 && pip install urllib3
升级pip：
$ pip install -U pip
如果有docker-py，则卸载掉，否则可能后面会报错：
$ pip uninstall docker-py
安装Kolla-Ansible：
$ pip install shade docker kolla ansible kolla-ansible
复制默认的Kolla-Ansible清单文件：
$ mkdir -pv /opt/kolla/config $ cd /opt/kolla/config $ cp -rv /usr/share/kolla-ansible/ansible/inventory/* .
复制默认的Kolla-Ansibe全局配置文件：
$ mkdir -pv /etc/kolla/ $ cp -rv /usr/share/kolla-ansible/etc_examples/kolla/* /etc/kolla/
配置Nova，由于是在虚拟机里，所以使用qemu，而不是kvm：
$ mkdir -pv /etc/kolla/config/nova $ vi /etc/kolla/config/nova/nova-compute.conf [libvirt] virt_type=qemu cpu_mode = none
生成随机密码文件：
$ kolla-genpwd
修改其中的admin密码，后面的Web页面会用到：
$ vi /etc/kolla/passwords.yml ... keystone_admin_password: admin ...
修改全局配置：
$ vi /etc/kolla/globals.yml ... docker_registry: "controller:4000" docker_namespace: "lokolla" kolla_install_type: "source" openstack_release: "5.0.1" ... kolla_internal_vip_address: "192.168.195.170" network_interface: "eth0" neutron_external_interface: "eth2" ... enable_haproxy: "no" ...
生成SSH Key，并授信本节点：
$ ssh-keygen $ ssh-copy-id -i ~/.ssh/id_rsa.pub root@controller
配置单节点清单文件（目前只有一个节点）：
$ /opt/kolla/config/ $ vi all-in-one ... [control] #localhost ansible_connection=local controller [network] #localhost ansible_connection=local controller [compute] #localhost ansible_connection=local controller [storage] #localhost ansible_connection=local controller [monitoring] #localhost ansible_connection=local controller [deployment] #localhost ansible_connection=local controller ...
检查配置是否正确：
$ kolla-ansible prechecks -i all-in-one
预先从Registry中把镜像拉出来：
$ kolla-ansible pull -i all-in-one
开始部署OpenStack：
$ kolla-ansible deploy -i all-in-one
生成环境变量设置脚本：
$ kolla-ansible post-deploy -i all-in-one $ cat /etc/kolla/admin-openrc.sh 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=admin export OS_AUTH_URL=http://192.168.195.170:35357/v3 export OS_INTERFACE=internal export OS_IDENTITY_API_VERSION=3 export OS_REGION_NAME=RegionOne
如果想清理掉部署好的OpenStack，则执行如下命令：
$ kolla-ansible destroy -i all-in-one --yes-i-really-really-mean-it
安装OpenStack命令行工具：
$ pip install python-openstackclient $ pip install python-neutronclient $ which openstack /usr/bin/openstack
设置环境变量：
$ . /etc/kolla/admin-openrc.sh
编辑初始化脚本中的网络配置：
$ vi /usr/share/kolla-ansible/init-runonce ... EXT_NET_CIDR='192.168.162.0/24' EXT_NET_RANGE='start=192.168.162.50,end=192.168.162.100' EXT_NET_GATEWAY='192.168.162.1' ...
初始化基本的运行环境（镜像和网络等）：
$ /usr/share/kolla-ansible/init-runonce

查看已有的网络的NameSpace：
$ ip netns qrouter-8ae967a2-72e6-4b6a-a7f8-a2349e4aa0d1 qdhcp-331baf0c-f09d-44a0-a59f-74372ee2da95
验证网络是否正常：
# 从路由的NameSpace测试虚拟机在"public1"网络的IP。 $ ip netns exec qrouter-8ae967a2-72e6-4b6a-a7f8-a2349e4aa0d1 ping 192.168.162.50 # 从DHCP的NameSpace测试虚拟机在"demo-net1"子网的IP。 $ ip netns exec qdhcp-331baf0c-f09d-44a0-a59f-74372ee2da95 ping 10.0.0.9
通过“Floating IP”访问虚拟机（用户名"cirros"，密码"cubswin:)"）：
$ ip netns exec qrouter-8ae967a2-72e6-4b6a-a7f8-a2349e4aa0d1 ssh cirros@192.168.162.50
通过子网IP访问虚拟机：
$ ip netns exec qdhcp-331baf0c-f09d-44a0-a59f-74372ee2da95 ssh cirros@10.0.0.9
通过“neutron-openvswitch-agent”容器访问虚拟机：
$ docker exec -it neutron_openvswitch_agent bash $ ssh cirros@192.168.162.50
