Vagrant + Ansible 解析超慢

Question

我使用 Vagrant 和 Ansible 创建了一个 VM，当我在启动后尝试使用它时，我注意到它非常慢。我也在云中使用远程数据库，但这似乎不是响应缓慢的原因。我所说的缓慢响应是指大部分时间加载页面大约需要 5 秒。

Vagrant 文件

# -*- 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

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

这对我来说增加了 10-15 倍的网络。
