vagrant WARNING: You are not using an encrypted connection

1. 开发环境:vagrant 1.7 + centos 6(i386) + LAMP
2. Drupal版本:7.53

---

在vagrant LAMP开发环境中，给Druapl安装模块时，显示WARNING: You are not using an encrypted connection, so your password will be sent in plain text的错误信息。

百度找了这个问题，使用

sudo chown -R www:www /path/to/drupal/

的方法，运行类似的命令之后，

再次ll之后，拥有者还是vagrant.

解决方法是，修改 vangrant 共享文件夹的 拥有者和用户组

修改vagrant 共享文件夹的权限

修改Vagrantfile中共享文件夹配置config.vm.synced_folder的拥有者和用户组，如:

config.vm.synced_folder "D:/developphp", "/var/www/html"

改为

config.vm.synced_folder "D:/developphp", "/var/www/html", :owner => "apache", :group => "apache"

Tips

1. 可以通过sudo cat /etc/passwd列出系统的所有用户
