proxmox Virtual Environment 7.4-3 安装记录

diskutil list
卸载所有分区
diskutil unmountDisk /dev/diskX
删除 U 盘中的所有分区
sudo diskutil eraseDisk free SPACE /dev/diskX
删除U盘分区，dd写入proxmox到U盘
sudo dd if=./proxmox-ve_7.4.1.iso of=/dev/disk3 bs=1M

• 主机开机按F11 选择U盘启动，正常输入ip，netmask, gateway,dns
• 去掉登陆弹窗及优化更新源

• 配置私有dhcp池和网桥，通过nat通信

apt install net-tools vim isc-dhcp-server
cd /etc/network/
cp interfaces interfaces-back0
添加vmbr1

root@pve:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp0s31f6 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.9.231/24
        gateway 192.168.9.1
        bridge-ports enp0s31f6
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
    address 192.168.122.1
    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 echo 1 > /proc/sys/net/ipv4/conf/vmbr1/proxy_arp
    post-up iptables -t nat -A POSTROUTING -s '192.168.122.0/24' -o vmbr0 -j MASQUERADE
    post-down iptables -t nat -D POSTROUTING -s '192.168.122.0/24' -o vmbr0 -j MASQUERADE

• 配置dhcp

cp /etc/dhcp/dhcpd.conf{,-back0}
cp /etc/default/isc-dhcp-server{,-back0}
root@pve:~# cat /etc/dhcp/dhcpd.conf |egrep -v "^#|^$"
option domain-name "dh-net.in";
option domain-name-servers 119.29.29.29, 8.8.8.8;
default-lease-time 600;
max-lease-time 7200;
ddns-update-style none;
authoritative;
log-facility local7;
subnet 192.168.122.0 netmask 255.255.255.0 {
  range 192.168.122.200 192.168.122.240;
  option domain-name-servers 119.29.29.29, 8.8.8.8, 8.8.4.4;
  option routers 192.168.122.1;
  option domain-name "dh-net.in";
  option broadcast-address 192.168.122.255;
  option netbios-node-type 8;
  get-lease-hostnames true;
  use-host-decl-names true;
  default-lease-time 600;
  max-lease-time 7200;
  interface vmbr1;
}
root@pve:~# cat /etc/default/isc-dhcp-server|egrep -v "^#|^$"
INTERFACESv4="vmbr1"
INTERFACESv6=""

• 启动服务，如果有异常自信看日志处理

systemctl restart  isc-dhcp-server.service
systemctl status isc-dhcp-server.service
