Vagrant Ansible provisioning SSH错误

Question

我正在尝试做一些Vagrant/Ansible的事情，但从一开始就遇到了问题。这是我的Vagrantfile：

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64"

  config.vm.network "private_network", ip: "192.168.6.66"

  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "2048"]
  end

  config.vm.provision "ansible" do |ansible|
    ansible.playbook = "site.yml"
  end
end

site.yml只是简单地

---
- name: Bring up server with MySQL, Nginx, and PHP-FPM
  hosts: all
  remote_user: root

  roles:
    - common

而common/task/main.yml是

---
- name: Update apt
  apt: update_cache=yes

在执行vagrant up时，输出为

如果我查看.vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory，，我会看到以下内容：

default ansible_ssh_host=127.0.0.1 ansible_ssh_port=2200

我希望那里的IP与private_network中设置的IP相同？我已经盯着这个看了一个多小时了，我是不是做错了什么？我有一种感觉，IP设置得不是很好。我可以ping 192.168.6.66。

这里的问题是，您的site.yml覆盖了ansible将用于root的远程用户。但是，您没有提供它的私钥，也没有提供密码。

因此，我修复的方法是将ansible_ssh_user设置为"vagrant"，因为它是默认的已知用户，如果remote_user没有被覆盖，ansible的行为将与vagrant ssh相同。并将sudo设置为true，因为"vagrant“用户是sudoer，而不是su。

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64"

  config.vm.network "private_network", ip: "192.168.6.66"

  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "2048"]
  end

  config.vm.provision "ansible" do |ansible|
    ansible.playbook = "site.yml"
    ansible.extra_vars = { ansible_ssh_user: 'vagrant' }
    ansible.sudo = true
    #ansible.verbose = 'vvvv'
  end
end

请参考“为什么ANSIBLE PROVISIONER以错误的用户身份连接？”第Ansible Provisioning of Vagrant Documentation节

Answer 2

Vagrant将创建自己的ansible清单文件(如您所见)，缺省值为127.0.0.1和2200。

您需要使用ansible.inventory_path指定ansible清单文件

与Vagrant配合使用的一个非常简单的清单文件可能如下所示：

默认ansible_ssh_host=192.168.111.222，其中上述IP地址是在Vagrantfile中设置的地址：

config.vm.network :private_network，ip："192.168.111.222“

我让Ansible在Vagrant1.7上尝试以root身份连接，可能是因为一些单独的部署repo group vars默认值。可能的修复方法：

根据changelog，默认情况下，

• set ansible.force_remote_user = true或ansible_ssh_user extra/host/group vars vagrant1.8会强制远程用户
