Ansible脚本ssh错误

Question

我正在 openstack (linux 虚拟机) 中创建一个虚拟机并从 there.I 启动 ansible 脚本，我收到以下 ssh 错误。

---
- hosts: licproxy
  user: my-user  
  sudo: yes
  tasks:

  - name: Install tinyproxy#
    command: sudo apt-get install tinyproxy

  - name: Update tinyproxy
    command: sudo apt-get update

  - name: Install bind9
    shell: yes '' | sudo apt-get install bind9

尽管我可以直接从 openstack admin-keydev29

中的 linux 框中通过 ssh 连接到机器 10.32.1.40

It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

我从 known_host 条目和运行脚本中删除了它仍然向我显示相同的消息。

更新

我发现手动 ssh 正在运行 fine.but ansible 脚本出现 ssh 错误。我使用 ssh 密钥登录到新创建的虚拟机并检查了 /var/log/auth.log file

Dec 30 13:00:33 licproxy-vm sshd[1184]: Server listening on :: port 22.
Dec 30 13:01:10 licproxy-vm sshd[1448]: error: Could not load host key: /etc/ssh/ssh_host_ed25519_key
Dec 30 13:01:10 licproxy-vm sshd[1448]: Connection closed by 192.168.0.106 [preauth]
Dec 30 13:01:32 licproxy-vm sshd[1450]: error: Could not load host key: /etc/ssh/ssh_host_ed25519_key

虚拟机有sshd版本OpenSSH_6.6.1版本我检查了 /etc/ssh 文件夹，我发现 ssh_host_ed25519_key 和 ssh_host_ed25519_key.pub 丢失了

我使用命令 ssh-keygen -A 创建了这些文件。

现在我想知道为什么 ssh 中缺少这些文件folder.Is这是一个错误吗？

Answer 1

问题是因为 ssh 端口 22.The 端口未启动。我添加了以下 code.which 基本上等待 ssh 端口出现。

while ! nc -z $PROXY_SERVER_IP 22; do
  sleep 10s
done
