使用salt-cloud创建openstack虚拟机

salt-cloud也是基于openstack来做的，它可以支持多种云的使用。比如：Aliyun、Azure、DigitalOcean、EC2、Google Compute Engine、HP Cloud、OpenStack、等等

安装相关组件和依赖包

[root@linux-node1 ~]# yum -y install salt-master salt-minion salt-cloud python-libcloud

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

                9f4f8a437ebc8123c1a8725156ee91566928d9f0

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）

    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
