我昨天开始使用Ansible并尝试在我的私有XenServer上配置VM。
我遵循了本指南： XenGuide Sharknet.us
因此，我可以使用ansible ping来访问Xen服务器。
我的项目文件夹具有以下结构：
Project Folder
|-- site.yml
|-- hosts (inventory file)
+-+ host_vars
| |-- master01.lab.local
| |-- master02.lab.local
| |-- slave01.lab.local
| |-- slave02.lab.local
+-+ group_vars
| |-- all
+-+ roles
| +-+ master
| | |-- main.yml
| +-+ slave
| | |-- main.yml
| +-+ vm
| | |-- create_vm.yml
| | |-- main.yml
我的文件Site.yml：
[vm]
master01.lab.local
master02.lab.local
slave01.lab.local
slave02.lab.local
[hypervisor]
xen01.lab.local
host_vars / master01.lab.local例如：
hostname: master01
ram: 8GiB
vcpus: 4
groups_vars / all file：
centos_template_uid: 11fd3dc9-96cc-49af-b091-a2ca7e94c589
primary_sr_uid: 6e074a6e-bf19-031d-7c65-c9ab2749a3da
user_network_uid: 087af565-bd27-cd0a-93e4-724beeb27735
角色/ VM / main.yml
- name: Check if VM exists
command: xe vm-list name-label={{ hostname }}
register: found
delegate_to: xen01.lab.local
- include: create_vm.yml
when: found.stdout == ""
- name: Wait for the Kickstart install to complete and the VM to reboot
local_action: wait_for host={{ hostname }}.lab.local port=22 delay=15 timeout=1200 state=started
角色/ VM / create_vm.yml
- name: Prevent template from creating storage
command: xe template-param-remove uuid={{ centos_template_uid }} param-name=other-config param-key=disks
ignore_errors: yes
delegate_to: xen01.lab.loca
- name: Create VM
command: xe vm-install template={{ centos_template_uid }} new-name-label="{{ hostname }}" sr-uuid={{ primary_sr_uid }}
register: vm
delegate_to: xen01.lab.local
- name: Set the repository location
command: xe vm-param-set uuid={{ vm.stdout }} other-config:install-repository="http://ansible-repo.lab.local/"
delegate_to: xen01.lab.local
- name: Set the location of the kickstart file
command: xe vm-param-set uuid={{ vm.stdout }} PV-args="ks=http://ansible-repo.lab.local/ks.cfg ksdevice=eth0"
delegate_to: xen01.lab.local
- name: Assign a network
command: xe vif-create vm-uuid={{ vm.stdout }} network-uuid={{ user_network_uid }} mac={{ mac }} device=0
delegate_to: xen01.lab.local
- name: Allocate VM storage
command: xe vdi-create name-label="{{ hostname }} storage" sr-uuid={{ primary_sr_uid }} type=system virtual-size=25GiB
register: disk
delegate_to: xen01.lab.local
- name: Assign storage to VM
command: xe vbd-create vdi-uuid={{ disk.stdout }} vm-uuid={{ vm.stdout }} type=Disk bootable=true device=0
delegate_to: xen01.lab.local
- name: Set the VM RAM limits
command: xe vm-memory-limits-set vm={{ vm.stdout }} static-min={{ ram }} static-max={{ ram }} dynamic-min={{ ram }} dynamic-max={{ ram }}
delegate_to: xen01.lab.local
- name: Set the number of CPUs
command: xe vm-param-set VCPUs-max={{ vcpus }} uuid={{ vm.stdout }}
delegate_to: xen01.lab.local
- name: Launch the VM
command: xe vm-start uuid={{ vm.stdout }}
delegate_to: xen01.lab.local
如果我现在运行以下命令：
ansible-playbook -i hosts site.yml -K
我收到以下错误：
ERROR! Syntax Error while loading YAML.
The error appears to have been in '/var/ansible/ansible-playbooks/provisioning/xen/roles/vm/tasks/main.yml': line 2, column 1, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: Check if VM exists
command: xe vm-list name-label={{ hostname }}
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"
有人知道这个错误吗？
答案 0 :(得分：0)
你应引用包含变量的字符串，所以在你的情况下

([Date] datetime, [Type] varchar(1), [ClassA] INT, [ClassB] INT)
;
INSERT INTO #Table1
([Date], [Type], [ClassA], [ClassB])
VALUES

同样适用于没有变量引号的所有其他任务
