如何在Java中发送大于127的字节daha？(How can i send a byte daha which is greater than 127 in Java?)

 vagrant-omnibus插件允许您提供任何脚本来安装厨师。 因此，如果您将chef install放入Vagrantfile所在的文件夹中，您可以指向一个如下所示的安装脚本： 
 
#!/usr/bin/env bash
dpkg --install /vagrant/chef_11.14.6-1_amd64.deb
 
 将它放在与Vagrantfile相同的文件夹中。 然后在你的Vagranfile中： 
 
config.omnibus.chef_version = '11.14.6'
config.omnibus.install_url = './chefinstall.sh'
 
 这应该工作。 它足够聪明，它将检查盒子上安装的Chef版本，并且仅在缺少该脚本时运行脚本。 
 
 您还可以使用vagrant cachier插件，因此无需每次都下载，最新版本的omnibus插件挂钩到缓存中： 
 
config.omnibus.cache_packages = true
 
 因此，如果您的主要问题是必须重复下载，请查看vagrant-cachier 

The vagrant-omnibus plugin allows you to give any script to install chef. So if you put the chef install into the folder where the Vagrantfile is, you could point to an install script that looks like:
 
#!/usr/bin/env bash
dpkg --install /vagrant/chef_11.14.6-1_amd64.deb
 
Put it in the same folder as your Vagrantfile. Then in your Vagranfile:
 
config.omnibus.chef_version = '11.14.6'
config.omnibus.install_url = './chefinstall.sh'
 
That should work. It's clever enough that it'll check what version of Chef is installed on the box, and only run the script if that's missing.
 
You could also use the vagrant cachier plugin, so it won't have to download everytime, the newest version of the omnibus plugin hooks into the cache:
 
config.omnibus.cache_packages = true
 
So if your main concern is having to download repeatably, check out vagrant-cachier
