    ip addr
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    inet 127.0.0.1/8 scope host lo

创建网桥

添加到 /etc/network/interfaces

其中 enp4s0 来自上一个命令的输出 2: enp4s0: <BROADCAST,MULTICAST

    auto vmbr1
    iface vmbr1 inet static
    address 192.168.48.1
    netmask 255.255.255.0
    bridge_ports none
    bridge_stp off
    bridge_fd 0
    post-up echo 1 > /proc/sys/net/ipv4/ip_forward
    post-up iptables -t nat -A POSTROUTING -s ‘192.168.48.0/24’ -o enp4s0 -j MASQUERADE
    post-down iptables -t nat -D POSTROUTING -s ‘192.168.48.0/24’ -o enp4s0 -j MASQUERADE

启动网桥

    ifup vmr1

    Waiting for vmbr1 to get ready (MAXWAIT is 2 seconds).

    ip address show dev vmbr1

    3: vmbr1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
    link/ether 16:cf:7e:23:de:1e brd ff:ff:ff:ff:ff:ff
    inet 192.168.48.1/24 brd 192.168.50.255 scope global vmbr1
    valid_lft forever preferred_lft forever
    inet6 fe80::14cf:7eff:fe23:de1e/64 scope link
    valid_lft forever preferred_lft forever

重启网络服务

    systemctl restart networking

编辑 /etc/default/isc-dhcp-server

    INTERFACESv4="vmbr1"

编辑 /etc/dhcp/dhcpd.conf

    option domain-name-servers 8.8.8.8, 8.8.4.4;
    default-lease-time 600;
    max-lease-time 7200;
    subnet 192.168.48.0 netmask 255.255.255.0 {
    range 192.168.48.100 192.168.48.199;
    option subnet-mask 255.255.255.0;
    option routers 192.168.48.1;
    option broadcast-address 192.168.48.255;
    }

    host host2 {
    hardware ethernet 00:00:00:00:00:02;
    fixed-address 192.168.48.2;
    infinite-is-reserved on;
    }
    host host3 {
    hardware ethernet 00:00:00:00:00:03;
    fixed-address 192.168.48.3;
    infinite-is-reserved on;
    }
    authoritative;

启动 DHCP 服务器

    systemctl start isc-dhcp-server

查看 DHCP 服务状态

    systemctl status isc-dhcp-server

推荐楼 sdqu 昨天21:51

apt-get install isc-dhcp-server

2楼 ecs 昨天21:00

hostloc记事本

3楼 zxxx 昨天21:07

请教大佬，小鸡可以使用DHCP自动获取IP吗？

5楼 557 昨天22:59

有啥好处？

6楼 zxxx 8小时前

有啥好处？

开小鸡用

7楼 jsdv 7小时前

没试过但想问：

Proxmox 直接弄个ikuai的小鸡会不会就代替网管和dhcp的功能了

8楼 zxxx 6小时前
