Vagrant + Ansible 解析超级慢

Question

我使用Vagrant和Ansible创建了一个虚拟机，但当我启动后使用时，发现它非常慢。我还在使用云中的远程数据库，但似乎不是缓慢响应的原因。所谓的缓慢响应是指大多数情况下加载页面需要约5秒钟。

Vagrantfile

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

# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
    # Set the box name and URL
    config.vm.box = "trusty-server"
    config.vm.box = "skeleton"
    config.vm.box_url = "https://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box"

    # Hostmanager plugin config
    config.hostmanager.enabled           = true
    config.hostmanager.manage_host       = true
    config.hostmanager.ignore_private_ip = false
    config.hostmanager.include_offline   = true


    # Fix TTY problem
    config.ssh.shell = "bash -c 'BASH_ENV=/etc/profile exec bash'"

    # Basic box configuration
    config.vm.network "private_network", ip: "192.168.100.102"
    config.vm.hostname = "skeleton.ontherocks.dev"
    config.hostmanager.aliases = %w(en.skeleton.ontherocks.dev)
    config.vm.synced_folder ".", "/vagrant", :mount_options => ['dmode=777', 'fmode=777']

    # Provision using Ansible
    config.vm.provision "ansible" do |ansible|
        ansible.playbook = "provisioning/playbook.yml"
    end

    config.vm.provision :hostmanager
end

你使用的是哪个提供程序，比如VirtualBox？你正在提供需要大量磁盘IO的内容吗？ - Emil Davtyan

VirtualBox，绝对不会有太多的磁盘IO。主机电脑并不是问题，因为在任何使用虚拟机的电脑上都会出现这种情况。 - mbalparda

尝试使用rsync同步文件夹，然后告诉我问题是否解决：config.vm.synced_folder(".", "/vagrant", type: "rsync") - Emil Davtyan

你是在Windows电脑上吗？ - Emil Davtyan

尝试使用rsync来查看是否有帮助，可能是同步的文件夹引起的。 - Emil Davtyan

Answer 1

使用nfs加速共享文件夹

 config.vm.synced_folder ".", "/vagrant", :nfs => { :mount_options => ["dmode=777","fmode=777"] }

加速虚拟机网络

 config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--nictype1", "virtio"]        
 end

这给我带来了10-15倍的网络提速。
