Vagrant Ansible配置SSH错误

Question

我正在尝试做一些Vagrant/Ansible的东西,但从一开始就遇到问题.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很简单

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

  roles:
    - common

和common/tasks/main.yml是

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

这样做vagrant up,输出是

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中设置的相同？我一直盯着这个看了一个多小时,我做错了吗？我有一种感觉,IP没有正确设置或其他东西.我可以ping 192.168.6.66.

这里的问题是你site.yml覆盖远程用户ansible将用于root.但是,您不提供私钥,也不提供密码.

所以,我修复它的方式是设置ansible_ssh_user为"vagrant",因为它是默认的已知用户,并且ansible的行为与vagrant sshremote_user不被覆盖的行为相同.并设置为sudotrue,因为"vagrant"用户是sudoer,但不是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

请参阅"为什么无法提供的设备与错误的用户连接？" 部分Ansible提供流浪文件

Answer 2

Vagrant 将创建它自己的 ansible inventory 文件（你已经看到了），默认值为 127.0.0.1 和 2200。

您需要使用指定 ansible inventory 文件ansible.inventory_path

与 Vagrant 一起使用的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 Vagrantfile 中的一组：

config.vm.network：私有网络，IP：“192.168.111.222”
