小編給大家分享一下如何使用Kolla-Ansible在CentOS 7單節點上部署OpenStack Pike，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！
雖然是進行單節點部署，但只要修改主機清單文件，在其他配置基本不變的情況下，也可以多節點部署。
這里使用了兩個網卡，除了Neutron的虛擬網絡在eth2上以外，其他的所有服務均放在eth0上。
由于eth2被Neutron放在了qrouter-XXX的網絡NameSpace中，所以宿主機無法直接通過eth2進行通信。
要想使用eth2的網絡，必須使用“ip netns exec qrouter-XXX”命令執行相關命令，或者建立一個網橋并綁定eth2和一個虛擬網卡，把虛擬網卡給Neutron使用，宿主機通過網橋使用eth2。
由于只有一個節點，所以禁用了"HAProxy"服務，并把所有VIP都設置為eth0的IP。
在VMware14中安裝CentOS 7 X64 1708發行版，最好是重新安裝一個精簡干凈的系統；
系統內存4G，空閑硬盤空間30G，內核版本為“3.10.0-693.11.6.el7.x86_64”；
有兩個網卡，eth0為“192.168.195.170”,eth2為“192.168.162.170”；
修改“/etc/hosts”，在其中增加“192.168.195.170 controller”。
官方對安裝Pike版本相關的軟件包版本要求如下：
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
啟動NTP服務：
$ systemctl enable ntpd.service && systemctl start ntpd.service && systemctl status ntpd.service
關閉libvirtd服務：
$ systemctl stop libvirtd.service && systemctl disable libvirtd.service && systemctl status libvirtd.service
關閉防火墻：
$ systemctl stop firewalld && systemctl disable firewalld && systemctl status firewalld
如果有的話，卸載舊的Docker，否則可能會不兼容：
$ yum remove -y docker docker-io docker-selinux python-docker-py
新增Docker的Yum倉庫：
$ 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
安裝Docker軟件包：
$ yum update $ yum install -y epel-release $ yum install -y docker-engine docker-engine-selinux
使用阿里的Docker鏡像服務（也可以自己去申請一個地址）：
$ mkdir -p /etc/docker
$ vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://7g5a4z30.mirror.aliyuncs.com"]
}重啟Docker服務：
$ systemctl daemon-reload && systemctl enable docker && systemctl restart docker && systemctl status docker
檢查鏡像服務是否正常：
$ 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/
運行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服務配置，信任本地Registry服務：
$ vi /usr/lib/systemd/system/docker.service ... #ExecStart=/usr/bin/dockerd ExecStart=/usr/bin/dockerd --insecure-registry controller:4000 ...
重啟Docker服務：
$ systemctl daemon-reload && systemctl restart docker
測試Registry服務是否正常：
$ curl -X GET http://controller:4000/v2/_catalog
{"repositories":[]}配置Docker共享掛載：
$ mkdir -pv /etc/systemd/system/docker.service.d $ vi /etc/systemd/system/docker.service.d/kolla.conf [Service] MountFlags=shared
重啟Docker服務：
$ systemctl daemon-reload && systemctl restart docker && systemctl status docker
下載OpenStack Pike的Docker鏡像：
$ wget http://tarballs.openstack.org/kolla/images/centos-source-registry-pike.tar.gz
解壓OpenStack Pike的Docker鏡像：
$ tar zxvf centos-source-registry-pike.tar.gz -C /opt/registry/
檢查Docker鏡像是否已經加入到Registry服務中（如果不能看到如下信息，則重啟Registry容器）：
$ curl -X GET http://controller:4000/v2/_catalog

$ docker restart registry
安裝依賴的軟件包：
$ yum install -y python-devel python-pip libffi-devel gcc openssl-devel git
如果后面出現urllib3錯誤，則把下面的命令執行兩次（出現的命令行交互中選擇“y”）：
$ pip uninstall urllib3 && pip install urllib3
升級pip：
$ pip install -U pip
如果有docker-py，則卸載掉，否則可能后面會報錯：
$ pip uninstall docker-py
安裝Kolla-Ansible：
$ pip install shade docker kolla ansible kolla-ansible
復制默認的Kolla-Ansible清單文件：
$ mkdir -pv /opt/kolla/config $ cd /opt/kolla/config $ cp -rv /usr/share/kolla-ansible/ansible/inventory/* .
復制默認的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，由于是在虛擬機里，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
生成隨機密碼文件：
$ kolla-genpwd
修改其中的admin密碼，后面的Web頁面會用到：
$ 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，并授信本節點：
$ ssh-keygen $ ssh-copy-id -i ~/.ssh/id_rsa.pub root@controller
配置單節點清單文件（目前只有一個節點）：
$ /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 ...
檢查配置是否正確：
$ kolla-ansible prechecks -i all-in-one
預先從Registry中把鏡像拉出來：
$ kolla-ansible pull -i all-in-one
開始部署OpenStack：
$ kolla-ansible deploy -i all-in-one
生成環境變量設置腳本：
$ 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，則執行如下命令：
$ kolla-ansible destroy -i all-in-one --yes-i-really-really-mean-it
安裝OpenStack命令行工具：
$ pip install python-openstackclient $ pip install python-neutronclient $ which openstack /usr/bin/openstack
設置環境變量：
$ . /etc/kolla/admin-openrc.sh
編輯初始化腳本中的網絡配置：
$ 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' ...
初始化基本的運行環境（鏡像和網絡等）：
$ /usr/share/kolla-ansible/init-runonce

$ openstack server list +--------------------------------------+-------+--------+------------------------------------+--------+---------+ | ID | Name | Status | Networks | Image | Flavor | +--------------------------------------+-------+--------+------------------------------------+--------+---------+ | 54bc1b6b-7930-4d5e-a661-b414c1eb4a2e | demo1 | ACTIVE | demo-net=10.0.0.9, 192.168.162.50 | cirros | m1.nano | +--------------------------------------+-------+--------+------------------------------------+--------+---------+
查看已有的網絡的NameSpace：
$ ip netns qrouter-8ae967a2-72e6-4b6a-a7f8-a2349e4aa0d1 qdhcp-331baf0c-f09d-44a0-a59f-74372ee2da95
驗證網絡是否正常：
# 從路由的NameSpace測試虛擬機在"public1"網絡的IP。 $ ip netns exec qrouter-8ae967a2-72e6-4b6a-a7f8-a2349e4aa0d1 ping 192.168.162.50 # 從DHCP的NameSpace測試虛擬機在"demo-net1"子網的IP。 $ ip netns exec qdhcp-331baf0c-f09d-44a0-a59f-74372ee2da95 ping 10.0.0.9
通過“Floating IP”訪問虛擬機（用戶名"cirros"，密碼"cubswin:)"）：
$ ip netns exec qrouter-8ae967a2-72e6-4b6a-a7f8-a2349e4aa0d1 ssh cirros@192.168.162.50
通過子網IP訪問虛擬機：
$ ip netns exec qdhcp-331baf0c-f09d-44a0-a59f-74372ee2da95 ssh cirros@10.0.0.9
通過“neutron-openvswitch-agent”容器訪問虛擬機：
$ docker exec -it neutron_openvswitch_agent bash $ ssh cirros@192.168.162.50
