yum install docker -y

4.配置镜像加速器

daocloud和阿里云都有相应的加速器，在实际的使用过程中，阿里云要比daocloud的快些。

vi /etc/docker/daemon.json

{

  "registry-mirrors": ["镜像加速地址"]

}

5.重启docker服务

systemctl daemon-reload && systemctl enable docker && systemctl restart docker && systemctl status docker

6.检查镜像服务是否正常

docker run --rm hello-world

7.安装相关依赖

yum install epel-release

yum install python-pip

pip install -U pip

yum install python-devel libffi-devel gcc openssl-devel libselinux-python

8.安装ansible

vi /etc/ansible/ansibel.cfg

[defaults]

host_key_checking=False

pipelining=True

forks=100

9.安装kolla-ansible

pip install kolla-ansible

cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/

cp /usr/share/kolla-ansible/ansible/inventory/* .

10.修改配置文件

vi all-in-one

[control]

#localhost       ansible_connection=local

kolla



[network]

#localhost       ansible_connection=local

kolla



# inner-compute is the groups of compute nodes which do not have

# external reachability

[inner-compute]

kolla



# external-compute is the groups of compute nodes which can reach

# outside

[external-compute]

#localhost       ansible_connection=local

kolla



[compute:children]

inner-compute

external-compute



[storage]

#localhost       ansible_connection=local

kolla



[monitoring]

#localhost       ansible_connection=local

kolla



[deployment]

#localhost       ansible_connection=local

11.生成随机密码文件

kolla-genpwd

vi /etc/kolla/passwords.yml

keystone_admin_password: admin123456

12.修改配置文件，安装所有需要的组件和其提供的服务

vi /etc/kolla/globals.yml

kolla_base_distro: "centos"

kolla_install_type: "source"

openstack_release: "pike"

kolla_internal_vip_address: "192.168.40.200"

network_interface: "eth0"

neutron_external_interface: "eth1"

kolla_internal_vip_address: "192.168.40.200"

enable_haproxy: "no"

13.配置ssh无密钥登陆，授权本节点

ssh-keygen

ssh-copy-id -i ~/.ssh/id_rsa.pub root@kolla

14.配置虚拟化类型

mkdir -pv /etc/kolla/config/nova

vi /etc/kolla/config/nova/nova-compute.conf

[libvirt]

virt_type=qemu

cpu_mode = none

15.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

16.部署OpenStack

检验配置

kolla-ansible -i ./all-in-one prechecks

拉取镜像

kolla-ansible pull -i ./all-in-one

开始部署

kolla-ansible -i ./all-in-one deploy

17.生成环境变量

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=admin123456

export OS_AUTH_URL=http://192.168.40.200:35357/v3

export OS_INTERFACE=internal

export OS_IDENTITY_API_VERSION=3

export OS_REGION_NAME=RegionOne

export OS_AUTH_PLUGIN=password

18.清理环境

kolla-ansible destroy -i all-in-one --yes-i-really-really-mean-it

19.创建虚拟机

安装命令行工具

pip install python-openstackclient python-glanceclient python-neutronclient

获取admin权限

source /etc/kolla/admin-openrc.sh

初始化虚拟机的运行环境

/usr/share/kolla-ansible/init-runonce
