vagrant file 设置固定IP并允许密码登录

How to use this box with Vagrant

Step 1

Option 1: Create a Vagrantfile and initiate the box
复制代码
vagrant init generic/centos9s --box-version 4.3.12
Option 2: Open the Vagrantfile and replace the contents with the following
复制代码
Vagrant.configure("2") do |config|
  config.vm.box = "generic/centos9s"
  config.vm.box_version = "4.3.12"
end
Step 2

Bring up your virtual machine
复制代码
vagrant up

复制代码

# vi: set ft=ruby :

  config.vm.box = "generic/centos9s"
  config.vm.box_version = "4.3.12"

  # 设置固定 IP
  config.vm.network "private_network", ip: "192.168.56.101"

  # 启用密码 SSH 登录（关键！）
  config.vm.provision "enable_password_auth", type: "shell", run: "always", inline: <<-SHELL
    if [ ! -f /etc/ssh/sshd_config.d/99-vagrant-password.conf ]; then
      echo "PasswordAuthentication yes" | sudo tee /etc/ssh/sshd_config.d/99-vagrant-password.conf
      sudo systemctl reload sshd
      echo "[INFO] Password authentication enabled for SSH."
    fi

  # 可选：VMware 或 VirtualBox 资源配置
  config.vm.provider "virtualbox" do |vb|
    vb.memory = "2048"
    vb.cpus = 2
  end

  config.vm.provider "vmware_desktop" do |vmware|
    vmware.memory = "2048"
    vmware.cpus = 2
  end
end
