使用salt-cloud创建openstack虚拟机


众所周知，saltstack有三大功能：远程执行、配置管理、云管理。其中的云管理就是通过salt-cloud完成的。salt-cloud能够管理很多云环境（公有云、私有云），连大名鼎鼎的阿里云也可以通过salt-cloud来创建虚拟机哦。


本次主要讲解使用salt-cloud管理openstack（L版）私有云来创建虚拟机。（前提openstack环境运行正常，能正常创建虚拟机）


1、 安装saltstack






yum install salt-master salt-minion salt-cloud -y






安装依赖包：






yum install python-libcloud -y






2、 创建provider配置文件，告诉salt-cloud如何连接openstack（yaml语法，注意空格）






[root@linux-node1 cloud.providers.d]# pwd

/etc/salt/cloud.providers.d

[root@linux-node1 cloud.providers.d]# vim openstack.conf

myopenstack:

  # Set the location of the salt-master

  #

  minion:

    master: 192.168.56.11

  # Configure the OpenStack driver

  #

  identity_url: http://192.168.56.11:5000/v2.0/tokens

  compute_name: nova

  protocol: ipv4

  compute_region: RegionOne

  # Configure Openstack authentication credentials

  #

  user: demo

  password: demo

  # tenant is the project name

  tenant: demo

  provider: openstack

  # skip SSL certificate validation (default false)

  insecure: false
 






3 、检查配置：


语法：


salt-cloud --list-locations <provider_name>    查看可用的区域


salt-cloud --list-p_w_picpaths <provider_name> 查看可用的镜像


salt-cloud --list-sizes <provider_name> 查看可用的虚拟机大小


例：查看可用的镜像






salt-cloud --list-p_w_picpaths myopenstack -l debug






myopenstack：provider配置文件中定义的ID


-l debug ：开启debug模式，方便定位和调试故障。






[root@linux-node1 ~]# salt-cloud --list-p_w_picpaths myopenstack -l debug

                serverId:

                    None

                status:

                    ACTIVE

                updated:

                    2015-12-13T14:24:05Z

                status:

                updated:

可以看到，当前有两个可用的镜像，cirros 和new ，并且可以看到更过镜像的信息。


4、 编写profile配置文件，告诉salt-cloud创建虚拟机的细节，后期创建虚拟机时只需要调用该名字即可。






[root@linux-node1 cloud.profiles.d]# vim openstack_web.conf

web-node:

  provider: myopenstack

  size: m1.tiny

  p_w_picpath: new

  ssh_key_file: /root/.ssh/id_rsa

  ssh_key_name: mykey

  ssh_interface: private_ips

  networks:

    - fixed:

      - 2c4c9edc-dbb8-467c-bc67-a2c6ff23d885

  minion:

    master: 192.168.56.11

    grains:

      role: webserver




5 、创建虚拟机








[root@linux-node1 cloud.profiles.d]# salt-cloud -p web-node test -l debug




-p 指定profile中虚拟机ID名称




6 、查看验证：






[root@linux-node1 ~]# nova list

--------------------+------+--------+------------+-------------+---------------------+

| ID                              | Name | Status | Task State | Power State | Networks            |

+-------------------+------+--------+------------+-------------+---------------------+

| b4035529-6cd7-4b9b-a6e9-c63d5bfb2d4b | test | ACTIVE | -          | Running     | flat=192.168.56.118 |

+-------------------+------+--------+------------+-------------+---------------------+






通过上面的配置文件，salt-cloud不仅能够创建虚拟机，还能够在虚拟机里安装salt-minion，


并自动添加到salt-master认证里面去（还设置了一个grains哦，很方便吧）


############################################################################################################3


官方手册： https://docs.saltstack.com/en/latest/topics/cloud/openstack.html


安装环境： 
172.16.1.211 salt-master服务器 
172.16.1.240 openstack控制节点


ps: 下面都在salt-master操作


1.安装插件：




yum install salt-cloud python-libcloud




2.创建salt-cloud配置文件：




mkdir /etc/salt/cloud.providers.d/

vim /etc/salt/cloud.providers.d/openstack.conf

my-openstack-config:

  minion:

    master: 172.16.1.211

  identity_url: http://172.16.1.240:5000/v2.0/tokens

  compute_name: nova

  protocol: ipv4

  compute_region: RegionOne

  user: demo

  password: demo

  tenant: demo

  driver: openstack

  provider: openstack

  insecure: false




3.查看镜像列表：




salt-cloud --list-images openstack  #查看镜像列表

salt-cloud --list-size openstack    #查看云主机类型




4.创建Salt-cloud虚拟机模板文件：




vim /etc/salt/cloud.profiles.d/web.conf

web-node:                                     #虚拟机模板名称

  provider: my-openstack-config               #前面配置文件定义的

  size: m1.tiny                               #云主机类型

  image: cirros                               #镜像名称

  ssh_key_file: /root/.ssh/id_rsa             #公钥文件

  ssh_key_name: mykey                         #密钥对名称

  ssh_interface: private_ips

  networks:

    - fixed:

      - 69200e49-0f8b-47b6-9bb5-2db9bca9a393  #网络的ID

  minion:                                     #下面是自动给虚拟机安装salt-minion并配置

    master: 172.16.1.211

    grains:

      role: webserver-01




4.通过Salt-cloud创建Openstack虚拟机：




salt-cloud -p web-node web-test1 -l debug

# -p: 虚拟机模板名称

# web-test1: 创建虚拟机的名称

# -l debug： 打印debug
