我们正在使用Vagrant和Ansible来配置VirtualBox机器.
它运行良好,但最近我们开始遇到一些奇怪的网络问题,需要访问互联网的任务,如：apt-get update,composer update,gem install等.这些问题不时出现,它们是不稳定.有时它无法连接到某个服务器或域名无法解析.
有趣的是,当我通过SSH(vagrant ssh)连接到盒子本身并手动发出这样的命令时,比如sudo apt-get update; sudo apt-get dist-upgrade – 它一直很好用.
这是NPM的示例错误：

我们使用以下方框：
@H_502_7@http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-i386-vagrant-disk1.Box主机操作系统是Ubuntu 14.04.
我们在完全不同的网络(不同的城市)中遇到不同计算机的这些问题.
这可能是什么原因？我们如何调试并修复它？
更新#1
Vagrantfile：
@H_502_7@# -*- mode: ruby -*- # vi: set ft=ruby : # "2" is an API version here. Vagrant.configure("2") do |config| config.vm.Box = "trusty32" config.vm.Box_url = "http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-i386-vagrant-disk1.Box" config.vm.hostname = "wa.local" config.vm.network "private_network",ip: "192.168.2.2" # Using NFS for now,cause native sharing is broken config.vm.synced_folder ".","/vagrant",nfs: true # Provisioning config.vm.provision "ansible" do |ansible| ansible.host_key_checking = false ansible.inventory_path = "ansible/inventory.ini" ansible.playbook = "ansible/vagrant.yml" ansible.limit = "all" end # Provider Configuration: VirtualBox config.vm.provider :virtualBox do |vb| # Setting RAM to 1 GB vb.memory = 1024 vb.customize ["modifyvm",:id,"--natdnshostresolver1","on"] end end更新#2
问题现在已经消失.我仍然不知道为什么它首先发生.也许我最近添加到Vagrantfile的行vb.customize [“modifyvm”,：id,“ – natdnshostresolver1”,“on”]有帮助.
谢谢你的所有建议！
