Proxmox PVE 9 增加硬盘重启后导致无法上网的解决方法

Proxmox PVE 9 增加硬盘导致无法上网主要是因为网卡名称发生变化导致，具体解决方法如下：

#首先查看网卡地址，执行命令
ip addr

#输出结果:
lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host noprefixroute 
       valid_lft forever preferred_lft forever
enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noop statc DOWN group default qlen 1000
    link/ether ec:d6:8a:bb:c2:3d brd ff:ff:ff:ff:ff:ff
    altname ebxecd68abf3d4f
vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
    link/ether EC:5C:89:DD:18:88 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.11/24 scope global vmbr0
       valid_lft forever preferred_lft forever
    inet6 fe80::ec5c:88ff:feff:2658/64 scope link proto kernel_ll
       valid_lft forever preferred_lft forever

#打开配置文件

nano /etc/network/interfaces

#文件内容：

auto lo
iface lo inet loopback
 
iface enp2s0 inet manual
 
auto vmbr0
iface vmbr0 inet static
        address 192.168.1.11/24
        gateway 192.168.1.1
        bridge-ports enp2s0
        bridge-stp off
        bridge-fd 0

source /etc/network/interfaces.d/*

将网卡名称enp2s0更改为通过ip addr查看实际网卡名称enp3s0，一共有两处，更改后输出的结果如下：

auto lo
iface lo inet loopback

iface enp3s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.11/24
gateway 192.168.1.1
bridge-ports enp3s0
bridge-stp off
bridge-fd 0

source /etc/network/interfaces.d/*

更改成功后，重启网络服务或者reboot重启电脑，就可以远程登录管理web界面。

systemctl restart networking
