Question

我有这一行：

sed -i 's/^\$cfg\['\''Servers'\''\]\[\$i\]\['\''AllowNoPassword'\''\] = .*/\$cfg\['\''Servers'\''\]\[\$i\]\['\''AllowNoPassword'\''\] = true;/' config.inc.php

将我的PHPMyAdmin config.inc.php AllowNoPassword编辑为true非常简单（当然这是一个开发环境）。

它在控制台中完美运行，但在使用vagrant的脚本文件中，它根本没有。

我确实认为这与'有关，但我无法理解其中的区别。

这里发生了什么以及如何解决？

这是一个完整的例子，减去一些逻辑来简化它并删除一些私人细节等：

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://atlas.hashicorp.com/search.
  config.vm.box = "ubuntu/xenial64"

  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  # NOTE: This will enable public access to the opened port
  # config.vm.network "forwarded_port", guest: 80, host: 8080

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine and only allow access
  # via 127.0.0.1 to disable public access
  config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"
  config.vm.network "forwarded_port", guest: 443, host: 4343, host_ip: "127.0.0.1"

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  # config.vm.network "private_network", ip: "192.168.33.10"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network "public_network"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  # config.vm.synced_folder "../data", "/vagrant_data"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  # config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # Define a Vagrant Push strategy for pushing to Atlas. Other push strategies
  # such as FTP and Heroku are also available. See the documentation at
  # https://docs.vagrantup.com/v2/push/atlas.html for more information.
  # config.push.define "atlas" do |push|
  #   push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"

  # Enable provisioning with a shell script. Additional provisioners such as
  # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the

使用转义 heredoc：

  $script = <<-'SCRIPT'
    cp config.sample.inc.php config.inc.php
    sed -i 's/^\$cfg\['\''Servers'\''\]\[\$i\]\['\''AllowNoPassword'\''\] = .*/\$cfg\['\''Servers'\''\]\[\$i\]\['\''AllowNoPassword'\''\] = true;/' config.inc.php
  SCRIPT

围绕SCRIPT的引号向Ruby解释器表明所有内容都应该是文字的 - 按照给定的精确而不是倾向于扩展。（这些引用在shell heredocs中具有相同的含义）。

带有反斜杠的sed脚本可在控制台或独立脚本中运行，但不适用于Vagrantfile
