为香港服务器配置静态IP地址是确保服务稳定性的基础步骤。与动态获取IP不同，静态IP保证服务器始终使用固定的网络地址，这对于Web服务、数据库、文件共享等需要稳定访问的服务至关重要。
一、配置前的准备工作
信息收集清单
bash
# 在配置前，需要准备以下信息：必需信息： ✓ 静态IP地址 ✓ 子网掩码（或CIDR前缀） ✓ 默认网关 ✓ DNS服务器地址 可选信息： ✓ 备用DNS服务器 ✓ 域名搜索后缀 ✓ 主机名
验证当前网络配置
bash
# Linux - 查看当前网络配置ip addr showip route showcat /etc/resolv.conf# Windows - 查看当前网络配置 ipconfig /all route print
二、Linux系统静态IP配置
方法一：使用Netplan（Ubuntu 18.04+）
基础静态IP配置
bash
# 1. 查看网络接口名称ip link show# 2. 编辑Netplan配置文件sudo nano /etc/netplan/01-netcfg.yaml# 3. 输入以下配置（根据实际情况修改）network: version: 2 renderer: networkd ethernets: ens33: addresses: - 192.168.1.100/24 routes: - to: default via: 192.168.1.1 nameservers: addresses: [8.8.8.8, 8.8.4.4] search: [localdomain]# 4. 应用配置sudo netplan apply# 5. 验证配置ip addr show ens33ping -c 3 8.8.8.8
高级Netplan配置
bash
# 多IP地址、多网关配置sudo nano /etc/netplan/01-netcfg.yaml network: version: 2 renderer: networkd ethernets: ens33: addresses: - 192.168.1.100/24 - 192.168.1.101/24 routes: - to: default via: 192.168.1.1 metric: 100 - to: 10.0.0.0/8 via: 192.168.1.254 metric: 200 nameservers: addresses: [8.8.8.8, 1.1.1.1, 208.67.222.222] search: [company.local, internal.company.com] optional: true# 应用配置sudo netplan apply
方法二：使用NetworkManager（CentOS/RHEL 8+）
nmcli命令行配置
bash
# 1. 查看网络连接nmcli connection show# 2. 添加新的静态IP连接sudo nmcli connection add con-name "static-eth0" ifname eth0 type ethernet \ ip4 192.168.1.100/24 gw4 192.168.1.1# 3. 配置DNSsudo nmcli connection modify "static-eth0" ipv4.dns "8.8.8.8,8.8.4.4"# 4. 设置手动IP分配方式sudo nmcli connection modify "static-eth0" ipv4.method manual# 5. 启用连接sudo nmcli connection up "static-eth0"# 6. 验证配置nmcli connection show "static-eth0"ip addr show eth0
修改现有连接为静态IP
bash
# 1. 查看当前连接nmcli connection show# 2. 修改现有连接（假设连接名为"Wired connection 1"）sudo nmcli connection modify "Wired connection 1" \ ipv4.addresses "192.168.1.100/24" \ ipv4.gateway "192.168.1.1" \ ipv4.dns "8.8.8.8,8.8.4.4" \ ipv4.method manual# 3. 重启连接sudo nmcli connection down "Wired connection 1"sudo nmcli connection up "Wired connection 1"# 4. 验证nmcli connection show "Wired connection 1"
方法三：传统配置文件方式（CentOS/RHEL 7及以下）
编辑网络接口配置文件
bash
# 1. 编辑接口配置文件sudo nano /etc/sysconfig/network-scripts/ifcfg-eth0# 2. 配置内容DEVICE=eth0BOOTPROTO=staticONBOOT=yesIPADDR=192.168.1.100NETMASK=255.255.255.0GATEWAY=192.168.1.1DNS1=8.8.8.8DNS2=8.8.4.4DOMAIN=company.localTYPE=EthernetUSERCTL=no# 3. 重启网络服务sudo systemctl restart network# 4. 验证配置ifconfig eth0netstat -rn
Debian/Ubuntu传统配置
bash
# 1. 编辑接口配置sudo nano /etc/network/interfaces# 2. 配置内容auto eth0 iface eth0 inet static address 192.168.1.100 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 8.8.8.8 8.8.4.4 dns-search company.local# 3. 重启网络服务sudo systemctl restart networking# 或者重启接口sudo ifdown eth0 && sudo ifup eth0
三、Windows服务器静态IP配置
方法一：图形界面配置
步骤详解
powershell
# 1. 打开网络连接设置ncpa.cpl# 2. 右键点击网络适配器 → 属性# 3. 选择"Internet协议版本4(TCP/IPv4)" → 属性# 4. 选择"使用下面的IP地址"# IP地址: 192.168.1.100# 子网掩码: 255.255.255.0# 默认网关: 192.168.1.1# 5. 选择"使用下面的DNS服务器地址"# 首选DNS: 8.8.8.8# 备用DNS: 8.8.4.4# 6. 点击"确定"保存# 验证配置ipconfig /all
方法二：PowerShell配置
基础静态IP配置
powershell
# 以管理员身份运行PowerShell# 1. 获取网络适配器信息Get-NetAdapter# 2. 配置静态IP地址（假设接口索引为12）New-NetIPAddress -InterfaceIndex 12 -IPAddress 192.168.1.100 -PrefixLength 24 -DefaultGateway 192.168.1.1# 3. 配置DNS服务器Set-DnsClientServerAddress -InterfaceIndex 12 -ServerAddresses 8.8.8.8, 8.8.4.4# 4. 验证配置Get-NetIPAddress -InterfaceIndex 12 | Format-TableGet-NetRoute -InterfaceIndex 12Get-DnsClientServerAddress -InterfaceIndex 12

七、最佳实践与安全考虑
安全配置建议
bash
# Linux - 配置防火墙规则sudo ufw allow from 192.168.1.0/24 to any port 22 # 只允许内网SSHsudo ufw allow out 53,80,443,123 # 允许必要的出站端口# Windows - 配置防火墙规则New-NetFirewallRule -DisplayName "Allow Internal SSH" -Direction Inbound -Protocol TCP -LocalPort 22 -RemoteAddress 192.168.1.0/24 -Action Allow
备份与恢复
bash
# Linux - 备份网络配置sudo cp /etc/netplan/01-netcfg.yaml /etc/netplan/01-netcfg.yaml.backupsudo cp /etc/resolv.conf /etc/resolv.conf.backup# Windows - 备份网络配置Export-NetAdapter -Name "Ethernet" -FileName "C:\backup\network-adapter.xml"Get-NetIPAddress | Export-Clixml "C:\backup\ip-config.xml"
结语
配置静态IP地址是服务器管理的基础技能，正确的配置确保：
核心价值：
服务稳定性：固定IP确保服务始终可访问
网络可预测性：便于网络规划和故障排除
安全控制：基于固定IP实施精确的访问控制
监控管理：稳定的地址便于监控系统跟踪
配置要点：
规划先行：合理规划IP地址分配，避免冲突
文档完整：记录所有网络配置信息
测试充分：配置后立即验证连通性
备份及时：备份原有配置以便恢复
后续优化：
实施IP地址管理（IPAM）系统
配置网络监控和告警
建立变更管理流程
定期进行网络配置审计
记住，在网络配置变更时，始终确保有备用访问方式（如IPMI、iDRAC、ILO等带外管理），以防配置错误导致失去服务器访问权限。
