如何编写IP配置切换脚本

  1. Windows 系统 - PowerShell 脚本
  2. Linux 系统 - Bash 脚本
  3. 使用说明

我来为您介绍几种不同操作系统下的IP配置切换脚本。

Windows 系统 - PowerShell 脚本

基础版 - 切换静态IP和DHCP

# Switch-NetworkConfig.ps1
param(
    [Parameter(Mandatory=$true)]
    [ValidateSet("Static", "DHCP")]
    [string]$Mode,
    [string]$IPAddress = "192.168.1.100",
    [string]$SubnetMask = "255.255.255.0",
    [string]$DefaultGateway = "192.168.1.1",
    [string]$DNSServer = "8.8.8.8"
)
$AdapterName = (Get-NetAdapter | Where-Object {$_.Status -eq "Up"})[0].Name
if ($Mode -eq "Static") {
    # 设置为静态IP
    Write-Host "正在设置静态IP..." -ForegroundColor Yellow
    # 移除原有配置
    Remove-NetIPAddress -InterfaceAlias $AdapterName -Confirm:$false -ErrorAction SilentlyContinue
    Remove-NetRoute -InterfaceAlias $AdapterName -Confirm:$false -ErrorAction SilentlyContinue
    # 设置新IP
    New-NetIPAddress -InterfaceAlias $AdapterName `
                    -IPAddress $IPAddress `
                    -PrefixLength 24 `
                    -DefaultGateway $DefaultGateway
    # 设置DNS
    Set-DnsClientServerAddress -InterfaceAlias $AdapterName `
                              -ServerAddresses ($DNSServer, "8.8.4.4")
    Write-Host "静态IP设置完成！" -ForegroundColor Green
    Write-Host "IP: $IPAddress" -ForegroundColor Cyan
    Write-Host "子网掩码: 255.255.255.0" -ForegroundColor Cyan
    Write-Host "网关: $DefaultGateway" -ForegroundColor Cyan
} elseif ($Mode -eq "DHCP") {
    # 设置为DHCP
    Write-Host "正在切换到DHCP..." -ForegroundColor Yellow
    Set-NetIPInterface -InterfaceAlias $AdapterName -Dhcp Enabled
    Set-DnsClientServerAddress -InterfaceAlias $AdapterName -ResetServerAddresses
    # 更新IP
    ipconfig /renew
    Write-Host "DHCP模式设置完成！" -ForegroundColor Green
    # 显示当前IP
    $ipInfo = Get-NetIPAddress -InterfaceAlias $AdapterName -AddressFamily IPv4
    Write-Host "当前IP地址: $($ipInfo.IPAddress)" -ForegroundColor Cyan
}

配置文件版本

配置文件 config.json：

{
    "profiles": {
        "office": {
            "ip": "192.168.1.100",
            "subnet": "24",
            "gateway": "192.168.1.1",
            "dns": ["8.8.8.8", "8.8.4.4"]
        },
        "home": {
            "dhcp": true
        },
        "dmz": {
            "ip": "10.0.0.50",
            "subnet": "16",
            "gateway": "10.0.0.1",
            "dns": ["10.0.0.1"]
        }
    }
}

高级脚本：

使用示例

# 设置为静态IP
.\Switch-NetworkConfig.ps1 -Mode Static -IPAddress 192.168.1.100
# 设置为DHCP
.\Switch-NetworkConfig.ps1 -Mode DHCP
# 使用配置文件
.\Advanced-IP-Switcher.ps1 -Profile office
# 查看所有配置
$config = Get-Content config.json -Raw | ConvertFrom-Json
$config.profiles.PSObject.Properties | Select-Object Name

使用说明

Windows脚本使用：

  1. 以管理员身份运行PowerShell
  2. 允许脚本执行：
    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
  3. 运行脚本

Linux脚本使用：

  1. 赋予执行权限：

    chmod +x ip-switcher.sh

  2. 以root权限运行：

    sudo ./ip-switcher.sh

注意事项：

  1. 管理员权限：大部分IP配置操作需要管理员/root权限
  2. 备份配置：切换前最好备份当前配置
  3. 网络连接：切换过程中可能会短暂断开网络
  4. 防火墙规则：如果使用防火墙，切换IP后可能需要更新规则

这些脚本覆盖了基本的IP配置切换需求,可以根据您的具体环境进行修改和扩展。
