ansible 一键部署openstack (双节点)
1.三台虚拟机设置
ansible
内存 2GB
处理器 4
硬盘 40GB
光盘iso centos1804
网络适配器 仅主机模式
显示器 自动检测
controller
内存 5.3GB
处理器 4
硬盘 100GB
光盘iso centos1804
网络适配器 仅主机模式
网络适配器 NAT模式
显示器 自动检测
compute
内存 5.3GB
处理器 4
硬盘 100GB
硬盘2 100GB
光盘iso centos1804
网络适配器 仅主机模式
网络适配器 NAT模式
显示器 自动检测
密码必须是000000
2.配置三台虚拟机的网络，主机名，域名解析
使用192.168.100.0网段
主机名 ansible controller compute
域名解析: （三台都需要配置）
[root@ansible ansible]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.128 ansible
192.168.100.130 controller
192.168.100.129 compute
[root@ansible ansible]#
3.下载ansible并配置免密登录
上传ansible.tar.gz 解压
[root@ansible ansible]# cd /opt/
[root@ansible opt]# ls
ansible ansible.tar.gz CentOS-7-x86_64-DVD-1804.iso chinaskills_cloud_iaas.iso rh
[root@ansible opt]#
[root@ansible opt]# tar -xzvf ansible.tar.gz -C ./
配置yum源安装ansible
配置列表清单
[root@ansible ansible]# cat hosts
controller
Compute
配置ansible
1.不检查公钥
2.hosts主机清单与roles在当前目录
3.远程用户为root
生成秘钥ssh-keygen使用
ssh-copy-id使ansible能够免密登录 compute controller
4.上传文件iaas镜像与centos1804镜像至ansible ansible将文件发送给被控节点
windows cmd上传镜像
scp CentOS-7-x86_64-DVD-1804.iso root@192.168.100.128:/opt
scp chinaskills_cloud_iaas.iso root@192.168.100.128:/opt
ansible 将文件传给被控节点
ansible all -m copy -a 'src=/opt/chinaskills_cloud_iaas.iso dest=/opt/' && ansible all -m copy -a 'src=/opt/CentOS-7-x86_64-DVD-1804.iso dest=/opt/'
5.ansible-playbook初始化操作
Controller
(1).挂载镜像拷贝出镜像的文件到/opt/iaas /opt/centos
(2).配置yum源
(3).下载vsftpd开启服务并共享/opt目录
Compute
(1).配置ftp yum源
(2).分区sdb
Controller/Compute
(1).关闭防火墙，不自启
(2).永久关闭selinux
(3).下载xiandian
生成init角色
ansible-galaxy init roles/init
编写playbook openstack_start.yml
- hosts: all
roles:
- init
编写roles init

运行剧本
6.编写jinjia2模板 渲染openrc.sh文件
(1).创建角色jinja2
ansible-galaxy init roles/jinja2
(2).控制节点Ansible下载iaas-xiandian并把openrc.sh做成模板文件
openrc.sh需要复制到jinji2角色的templates目录下
注意配置yum获取controller的ftp仓库
[root@ansible templates]# cp /etc/xiandian/openrc.sh ./openrc.sh.j2
[root@ansible templates]# ls
openrc.sh.j2
(3).去除变量信息的#
sed -i 's/^#//g' openrc.sh.j2
(4).写入变量

(5).渲染变量
被定义的变量放进jinja2角色模板里的vars
剧本运行时playbook的template模块用vars里的变量渲染jinja2模板
[root@ansible ansible]# cat roles/jinja2/vars/main.yml
controller_ip: 192.168.100.130
controller_name: controller
compute_ip: 192.168.100.129
compute_name: compute
PASSWD: '000000'
cinder_disk: sdb1
swift_disk: sdb2
network_segment_IP: 192.168.100.0
External_Network: ens33
Physical_NAME: provider
STORAGE_LOCAL_NET_IP: 192.168.100.129
[root@ansible ansible]#
(6).编写并运行playbook
[root@ansible ansible]# cat jinja2.yml
- hosts: all
roles:
- jinja2
[root@ansible ansible]# ansible-playbook jinja2.yml
7.跑xiandian里的脚本完成openstack的安装
(1).生成所需要的角色
[root@ansible ansible]# for i in {mariadb,keystone,glance,nova-controller,neutron-controller,dashboard,cinder-controller,swift-controller,heat,nova-compute,neutron-compute,cinder-compute,swift-compute};do ansible-galaxy init roles/$i ;done
- Role roles/mariadb was created successfully
- Role roles/keystone was created successfully
- Role roles/glance was created successfully
- Role roles/nova-controller was created successfully
- Role roles/neutron-controller was created successfully
- Role roles/dashboard was created successfully
- Role roles/cinder-controller was created successfully
- Role roles/swift-controller was created successfully
- Role roles/heat was created successfully
- Role roles/nova-compute was created successfully
- Role roles/neutron-compute was created successfully
- Role roles/cinder-compute was created successfully
- Role roles/swift-compute was created successfully
[root@ansible ansible]#
每个角色对应着自己的名字的脚本任务
(2).写上每个角色对应的命令
controller
mariadb/tasks/main.yml
- name: install mysql
shell: iaas-install-mysql.sh
keystone/tasks/main.yml
- name: install keystone
shell: iaas-install-keystone.sh
glance/tasks/main.yml
- name: install glance
shell: iaas-install-glance.sh
nova-controller/tasks/main.yml
- name: install nova-controller
shell: iaas-install-nova-controller.sh
neutron/tasks/main.yml
- name: install neutron-controller
shell: iaas-install-neutron-controller.sh
dashboard/tasks/main.yml
- name: install dashboard
shell: iaas-install-dashboard.sh
cinder/tasks/main.yml
- name: install cinder-controller
shell: iaas-install-cinder-controller.sh
swift/tasks/main.yml
- name: install swift-controller
shell: iaas-install-swift-controller.sh
heat/tasks/main.yml
- name: install heat
shell: iaas-install-heat.sh
compute
nova/tasks/main.yml
- name: install nova-compute
shell: iaas-install-nova-compute.sh
neutron/tasks/main.yml
- name: install neutron-compute
shell: iaas-install-neutron-compute.sh
cinder/tasks/main.yml
- name: install cinder-compute
shell: iaas-install-cinder-compute.sh
swift/tasks/main.yml
- name: install swift-compute
shell: iaas-install-swift-compute.sh
(3).剧本内容
[root@ansible ansible]# cat openstack_shell.yml
- hosts: controller
remote_user: root
pre_tasks:
- name: init
shell: iaas-pre-host.sh
roles:
- mariadb
- keystone
- glance
- nova-controller
- neutron-controller
- dashboard
- cinder-controller
- swift-controller
- heat
- hosts: compute
remote_user: root
pre_tasks:
- name: init
shell: iaas-pre-host.sh
roles:
- nova-compute
- neutron-compute
- cinder-compute
- swift-compute
7.合并剧本
[root@ansible ansible]# cat final.yml
- hosts: all
tasks:
- name: cp iaas
copy:
src: /opt/chinaskills_cloud_iaas.iso
dest: /opt/
- name: cp centos
copy:
src: /opt/CentOS-7-x86_64-DVD-1804.iso
dest: /opt/ # 这一步可以代替第标题4的ansible
- hosts: all
roles:
- init
- hosts: all
roles:
- jinja2
- hosts: controller
remote_user: root
pre_tasks:
- name: init
shell: iaas-pre-host.sh
roles:
- mariadb
- keystone
- glance
- nova-controller
- neutron-controller
- dashboard
- cinder-controller
- swift-controller
- heat
- hosts: compute
remote_user: root
pre_tasks:
- name: init
shell: iaas-pre-host.sh
roles:
- nova-compute
- neutron-compute
- cinder-compute
- swift-compute
ansible-playbook final.yml
至此一键部署openstack完成
被控节点只需要修改主机名，配好网络，密码000000，可以被ansible免密登录
