Vagrant 具有专用网络的Centos7丢失了固定IP

我有一个centos7流浪者包厢的网络问题。 当我使用固定IP设置一个专用网络时，这个网络首先绑定良好，但几秒钟/分钟后就会丢失

使用此流浪者文件：

vagrant.configure(2) do |config|

 config.vm.box = "centos7"
 config.vm.hostname = "docker-registry"
 config.vm.box_url = "https://github.com/holms/vagrant-centos7-box/releases/download/7.1.1503.001/CentOS-7.1.1503-x86_64-netboot.box"

 #config.vm.network "public_network"
 config.vm.network "private_network", ip: "192.168.100.20"
 #config.vm.synced_folder ".", "/vagrant", type: "nfs"

 # VirtualBox
 config.vm.provider :virtualbox do |vb|
   vb.name = "poc_docker"
   vb.memory = 3072
   vb.cpus = 2
   vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
   vb.customize ["modifyvm", :id, "--natdnsproxy1", "on"]
 end


end

当我连接到盒子上时，似乎ip丢失了

sudo /sbin/ifup eth1

暂时修复该问题，但IP会再次丢失。 重新启动该框（vagrant halt&&vagrant up）似乎可以永久解决问题。 我试图用Packer（）创建一个定制的centos 7 box，我也复制了这个问题

我想这是Centos 7的具体问题吧？ 你已经有同样的问题了吗？有没有办法通过添加一个vagrant命令来解决这个问题

我的环境：

约塞米蒂 ➜ ~ 流浪汉版 流浪汉1.7.2 ➜ ~ VBoxManage--版本

---

4.3.26R988

这似乎是由于DHCP配置造成的问题（问题：）

网络服务不会重新加载NetworkManager，因此它将继续等待dhcp租约。。dhcp超时后，固定ip被删除

使用添加shell提供脚本

sudo nmcli connection reload
sudo systemctl restart network.service

解决了这个问题

编辑：

vagrant 1.7.3+也修复了该漏洞；）

在更新的Vagrant版本（1.9.1）中似乎也存在类似的问题

修复该问题的拉取请求已合并（尚未发布）：

如果要应用该修复程序，可以尝试以下操作（sudo可能是必需的，具体取决于文件权限）：

找到您的本地Vagrant安装（在Fedora上是

/opt/Vagrant/

）

移动到流浪者宝石的文件夹：

cd embedded/gems/gems/vagrant-1.9.1

初始化新的Git存储库并添加GitHub remote：

git init
git remote add origin https://github.com/mitchellh/vagrant.git
git fetch --all

签出新分支并将其重置为当前版本（例如1.9.1）

如果不确定是否有本地更改，请在重置后使用

--hard

执行

git diff

/

git签出

：

git checkout -b hotfixes
git reset --hard v1.9.1

现在应用修补程序：

git cherry-pick 96611341a96d7d19fdade5556a110b22c6add22b

之后，流浪者重新加载应能正常启动本地网络。

中提到了修复方法：

在

/opt/vagrant/embedded/gems/gems/vagrant-1.9.1/plugins/guests/redhat/cap/configure_networks.rb

中

---

在

nmcli c reload | | | true

之后添加

/sbin/ifup'{network[：device]}'

，奇怪的是，我的设置几乎相同，但仍然运行centos 6.5，而且工作正常。你能把你运行的shell脚本放进去吗？它会扰乱网络吗？此外，您还可以升级虚拟机Guestadition，因为我已经删除了shell脚本。还是sameThank谢谢你发这个帖子。我花了一天的大部分时间试图解决这个问题。这解决了很多问题。我真的不明白为什么这个修补程序在11天前被合并了，但它仍然没有在可下载的二进制文件中。这似乎是一个非常重要的问题。这只是救了我的命。非常感谢！是的，这为我修复了它，使用Centos 7和Vagrant 1.9.1。在1.9.1上为我工作，使用网站上的基本Centos box安装
