使用salt-cloud创建虚拟机

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

废话不说直接看如何部署

安装相关组件和依赖包

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

修改配置文件

[root@linux-node1 ~]# cd /etc/salt/cloud.providers.d/
[root@linux-node1 cloud.providers.d]# cat openstack.conf 
my-openstack-config:
  # 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
  # 注意这里的类型可以通过openstack endpoint list 查看到

  # Configure Openstack authentication credentials
  #
  user: demo
  password: demo
  # tenant is the project name
  tenant: demo
  # 项目名称

  provider: openstack

  # skip SSL certificate validation (default false)
  insecure: false

配置saltstack

[root@linux-node1 cloud.providers.d]# systemctl start salt-master
[root@linux-node1 cloud.providers.d]# vim /etc/salt/minion 
master: 192.168.56.12
[root@linux-node1 cloud.providers.d]# systemctl start salt-minion
[root@linux-node1 cloud.providers.d]# salt-key 
Accepted Keys:
Denied Keys:
Unaccepted Keys:
linux-node1.oldboyedu.com
Rejected Keys:
[root@linux-node1 cloud.providers.d]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
linux-node1.oldboyedu.com
Proceed? [n/Y] y
Key for minion linux-node1.oldboyedu.com accepted.

[root@linux-node1 cloud.providers.d]# salt '*' test.ping
linux-node1.oldboyedu.com:
True

测试salt-cloud能否连接上openstack

##### 列出所有云主机的类型

[root@linux-node1 cloud.providers.d]# salt-cloud --list-size openstack -l debug

编写虚拟机的创建文件

[root@linux-node1 cloud.profiles.d]# pwd
/etc/salt/cloud.profiles.d

[root@linux-node1 cloud.profiles.d]# cat web.conf 
web-node:
  provider: my-openstack-config                 # /etc/salt/cloud.providers.d/openstack.conf的ID
  size: m1.tiny                                 # 云主机的类型

  ssh_interface: private_ips
  networks:                                     # 设置使用的网络，可以从openstack页面的网络板块中找

  minion:
    master: 192.168.56.11
    grains:
      role: webserver
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[root@linux-node1 cloud.profiles.d]# salt-cloud -p web-node node1 -l debug

执行后，可以在web界面看见创建的虚拟机node1，但是有个问题没有解决，就是可以远程，但是6080 vnc不能使用。。。。。。。。后续解决。。。。
