PVE 迁移新网络网段配置

玩机教程 > Proxmox VE/PVE (878) 2025-02-06 16:49:30

举例

当前网络环境

ip address : 192.168.31.119/24

gateway: 192.168.31.1

dns:192.168.31.1

目标网络环境

ip address : 192.168.1.119/24

gateway: 192.168.1.1

dns: 192.168.1.1

修改 IP 地址

编辑 /etc/network/interfaces。

auto lo
iface lo inet loopback
iface enp1s0 inet manual
auto vmbr0
iface vmbr0 inet static
    address 192.168.31.119/24
    gateway 192.168.31.1
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0
iface enp2s0 inet manual
iface wlo1 inet manual

修改后

auto lo
iface lo inet loopback
iface enp1s0 inet manual
auto vmbr0
iface vmbr0 inet static
    address 192.168.1.119/24
    gateway 192.168.1.1
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0
iface enp2s0 inet manual
iface wlo1 inet manual

这里有一点需要注意，如果是更换主板或者添加新网卡，可能导致配置文件里面的网卡名不一样，注意修改成一致的。

使用命令 ip addr 查看网卡名
2: enp0s31f6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmbr0 state UP group default qlen 1000
   link/ether 6c:4b:90:42:7e:57 brd ff:ff:ff:ff:ff:ff
再编辑interfaces里面网卡名部分修改对应的
vi /etc/network/interfaces

auto lo
iface lo inet loopback
auto enp0s31f6
iface enp0s31f6 inet manual
auto vmbr0
iface vmbr0 inet static
       address 172.16.1.119/24
       gateway 172.16.1.1
       bridge-ports enp0s31f6
       bridge-stp off
       bridge-fd 0
iface wlo1 inet manual

source /etc/network/interfaces.d/*
这里网卡名为enp0s31f6

修改 hosts

编辑 /etc/hosts

127.0.0.1 localhost.localdomain localhost
192.168.31.119 pve.lan pve
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

主要修改的就是映射地址 192.168.31.119→pve.lan pve

修改后：

127.0.0.1 localhost.localdomain localhost
192.168.1.119 pve.lan pve
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

修改 DNS (必要时修改)

编辑 /etc/resolv.conf。

search lan
nameserver 192.168.31.1

修改后：

search lan
nameserver 192.168.1.1

修改终端提示的 URL（可改可不该，只是提示，自己记住就行）

编辑 /etc/issue。

所有修改玩成后关机，然后新网络环境连接网线并开机。
