如何在代理环境中使用流浪汉？

Install proxyconf:

vagrant plugin install vagrant-proxyconf

Configure your Vagrantfile:

config.proxy.http     = "http://yourproxy:8080"
config.proxy.https    = "http://yourproxy:8080"
config.proxy.no_proxy = "localhost,127.0.0.1"

Installing proxyconf will solve this, but behind a proxy you can't install a plugin simply using the command vagrant plugin install, Bundler will raise an error.

set your proxy in your environment if you're using a unix like system

export http_proxy=http://user:password@host:port

or get a more detailed answer here: How to use bundler behind a proxy?

after this set up proxyconf

If your proxy requires authentication it is better to set the environment variable rather than storing your password in the Vagrantfile. Also your Vagrantfile can be used by others easily who are not behind a proxy.

For Mac/Linux (in Bash)

export http_proxy="http://user:password@host:port"
export https_proxy="http://user:password@host:port"
vagrant plugin install vagrant-proxyconf

then

export VAGRANT_HTTP_PROXY=${http_proxy}
export VAGRANT_HTTPS_PROXY=${https_proxy}
export VAGRANT_NO_PROXY="127.0.0.1"
vagrant up

For Windows use set instead of export.

set http_proxy=http://user:password@host:port
set https_proxy=https://user:password@host:port
vagrant plugin install vagrant-proxyconf

then

set VAGRANT_HTTP_PROXY=%http_proxy%
set VAGRANT_HTTPS_PROXY=%https_proxy%
set VAGRANT_NO_PROXY="127.0.0.1"
vagrant up

Auto detect your proxy settings and inject them in all your vagrant VM

install the proxy plugin

vagrant plugin install vagrant-proxyconf

add this conf to you private/user VagrantFile (it will be executed for all your projects) :

vi $HOME/.vagrant.d/Vagrantfile

Vagrant.configure("2") do |config|
puts "proxyconf..."
if Vagrant.has_plugin?("vagrant-proxyconf")
puts "find proxyconf plugin !"
if ENV["http_proxy"]
puts "http_proxy: " + ENV["http_proxy"]
config.proxy.http     = ENV["http_proxy"]
end
if ENV["https_proxy"]
puts "https_proxy: " + ENV["https_proxy"]
config.proxy.https    = ENV["https_proxy"]
end
if ENV["no_proxy"]
config.proxy.no_proxy = ENV["no_proxy"]
end
end
end

now up your VM !

In MS Windows this works for us:

set http_proxy=< proxy_url >
set https_proxy=< proxy_url >

And the equivalent for *nix:

export http_proxy=< proxy_url >
export https_proxy=< proxy_url >

On a Windows host

open a CMD prompt;

set HTTP_PROXY=http://proxy.yourcorp.com:80
set HTTPS_PROXY=https://proxy.yourcorp.com:443

Substitute the address and port in the above snippets to whatever is appropriate for your situation. The above will remain set until you close the CMD prompt. If it works for you, consider adding them permanently to your environment variables so that you won't have to set them every time you open a new CMD prompt.

The question does not mention the VM Provider but in my case, I use Virtual Box under the same environment. There is an option in the Virtual Box GUI that I needed to enable in order to make it work. Is located in the Virtual Box app preferences: File >> Preferences... >> Proxy. Once I configured this, I was able to work without problems. Hope this tip can also help you guys.

On windows, you must set a variable to specify proxy settings, download the vagrant-proxyconf plugin: (replace {PROXY_SCHEME}(http:// or https://), {PROXY_IP} and {PROXY_PORT} by the right values)

set http_proxy={PROXY_SCHEME}{PROXY_IP}:{PROXY_PORT}
set https_proxy={PROXY_SCHEME}{PROXY_IP}:{PROXY_PORT}

After that, you can add the plugin to hardcode your proxy settings in the vagrant file

vagrant plugin install vagrant-proxyconf --plugin-source http://rubygems.org

and then you can provide config.proxy.xxx settings in your Vagrantfile to be independent against environment settings variables

You will want to install the plugin proxyconf since this makes configuring the proxy for the guest machines pretty straight forward in the VagrantFile

config.proxy.http     = "http://proxy:8888"
config.proxy.https    = "http://proxy:8883"
config.proxy.no_proxy = "localhost,127.0.0.1"

However, there's quite a few things that could still go wrong. Firstly, you probably can't install vagrant plugins when behind the proxy. If that's the case you should download the source e.g. from rubygems.org and install from source

$ vagrant plugin install vagrant-proxyconf --plugin-source file://fully/qualified/path/vagrant-proxyconf-1.x.0.gem

If you solve that problem you might have the fortune of being behind an NTLM proxy, which means that if you are using *nix on your guest machines then you still have some way to go, because NTLM authentication is not supported natively There are many ways of solving that. I've used CNTLM to solve tht part of the puzzle. It acts as glue between standard authorization protocols and NTLM

For a complete walk through, have a look at this blog entry about setting vagrant up behind a corporate proxy

If you actually do want your proxy configurations and plugin installations to be in your Vagrantfile, for example if you're making a Vagrantfile just for your corporate environment and can't have users editing environment variables, this was the answer for me:

ENV['http_proxy']  = 'http://proxyhost:proxyport'
ENV['https_proxy'] = 'http://proxyhost:proxyport'


# Plugin installation procedure from http://stackoverflow.com/a/28801317
required_plugins = %w(vagrant-proxyconf)


plugins_to_install = required_plugins.select { |plugin| not Vagrant.has_plugin? plugin }
if not plugins_to_install.empty?
puts "Installing plugins: #{plugins_to_install.join(' ')}"
if system "vagrant plugin install #{plugins_to_install.join(' ')}"
exec "vagrant #{ARGV.join(' ')}"
else
abort "Installation of one or more plugins has failed. Aborting."
end
end


Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.proxy.http     = "#{ENV['http_proxy']}"
config.proxy.https    = "#{ENV['https_proxy']}"
config.proxy.no_proxy = "localhost,127.0.0.1"
# and so on

(If you don't, just set them as environment variables like the other answers say and refer to them from env in config.proxy.http(s) directives.)

Some Special characters in the password create problem in proxy. Either escape them or avoid having special characters in password.

In PowerShell, you could set the http_proxy and https_proxy environment variables like so:

$env:http_proxy="http://proxy:3128"
$env:https_proxy="http://proxy:3128"
