（centOS）cloud-init 不拉 ssh

尝试使用 OpenStack 指南构建 CentOS 6 qcow2 映像[http://docs.openstack.org/image-guide/content/centos-image.html]。我使用的是“cloud-init”而不是“/etc/rc.d/rc.local”脚本，但我假设“cloud-init”会覆盖该脚本？我成功创建了映像，上传并创建了实例。但无法通过 ssh 进入。我怀疑该实例没有从 OpenStack 服务器/控制器中提取 ssh 公钥。

[更新：尝试通过密码允许 ssh 的替代方法]

这些是我从 OpenStack 管理页面获取的日志。

这些是一些重要文件的配置文件。我的实例无法使用我编辑的“cloud.cfg”启动。我需要将它们放在单独的文件中吗？

[/etc/sudoers]

centos ALL = (ALL) NOPASSWD: ALL
## Allows members of the 'sys' group to run networking, software, 
## service management apps and more.
# %sys ALL = NETWORKING, SOFTWAR

[/etc/cloud/cloud.cfg]

控制台也不起作用。我是否添加了正确的控制台行？

我的实例无法通过我编辑的“cloud.cfg”启动。我需要将它们放在单独的文件中吗？这会启用“ssh centos@ip-address”并使用密码“centos”吗？

我的问题似乎与无法在 Openstack 中 ssh 进入 Centos 虚拟机

答案1

OpenStack qcow 配置文件非常挑剔。语法必须采用精确的格式。（间距等）。

[/etc/cloud/cloud.cfg]

system_info:
  default_user:

    lock_passwd: true
    gecos: Cloud User
    groups: [wheel, adm]

    shell: /bin/bash
  distro: rhel
  paths:

password: centos
chpasswd: { expire: False }
ssh_pwauth: True
