    4. TYPE=Bridge
    5. PROXY_METHOD=none
    6. BROWSER_ONLY=no
    7. BOOTPROTO=shared
    8. IPADDR=192.168.138.1
    9. PREFIX=24
    10. GATEWAY=192.168.138.1
    11. DEFROUTE=yes
    12. IPV4_FAILURE_FATAL=no
    13. IPV6INIT=yes
    14. IPV6_AUTOCONF=yes
    15. IPV6_DEFROUTE=yes
    16. IPV6_FAILURE_FATAL=no
    17. IPV6_ADDR_GEN_MODE=stable-privacy
    18. NAME=bridge2
    19. UUID=645ad06d-5886-48eb-bed1-700ff6165799
    20. DEVICE=bridge2
    21. ONBOOT=yes

  3. 配置 ifcfg-eth1

    1. nmcli connection delete eth1
    2. nmcli connection add type ethernet con-name eth1 ifname eth1 master bridge2 autoconnect yes
    1. TYPE=Ethernet
    2. NAME=eth1
    3. UUID=96c7b152-f591-4b3b-8a2e-af9bf2dd9f9c
    4. DEVICE=eth1
    5. ONBOOT=yes
    6. BRIDGE=bridge2

  4. 创建热点 ifcfg-ap

    1. nmcli device wifi hotspot ifname wlan0 password 12345678 ssid HelloWorld con-name ap

    ```bash

    ifcfg-ap 内容

    ESSID=HelloWorld MODE=Ap KEY_MGMT=WPA-PSK WPA_ALLOW_WPA2=yes CIPHER_PAIRWISE=CCMP CIPHER_GROUP=CCMP MAC_ADDRESS_RANDOMIZATION=default TYPE=Wireless PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=shared DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=no IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ap UUID=0d929e2a-ff7a-44a2-a309-bc6f97434b7b DEVICE=wlan0 ONBOOT=no

keys-ap 内容

WPA_PSK=12345678

  2. 5. 创建网桥节点 ifcfg-wlan0
  3. ```bash
  4. nmcli connection add type wifi mode ap ssid wifi名称 con-name wlan0 ifname wlan0 master bridge2 autoconnect yes
  6. # 生成内容如下
  7. ESSID=HelloWorld
  8. MODE=Ap
  9. MAC_ADDRESS_RANDOMIZATION=default
  10. TYPE=Wireless
  11. NAME=wlan0
  12. UUID=7a9449a8-f889-4e11-bd04-d45aa063b677
  13. DEVICE=wlan0
  14. ONBOOT=yes
  15. BRIDGE=bridge2
ESSID=HelloWorld
MODE=Ap
MAC_ADDRESS_RANDOMIZATION=default
TYPE=Wireless
NAME=wlan0
UUID=7a9449a8-f889-4e11-bd04-d45aa063b677
DEVICE=wlan0
ONBOOT=yes
BRIDGE=bridge2
# 添加以下内容，内容来自 ifcfg-ap
KEY_MGMT=WPA-PSK
WPA_ALLOW_WPA2=yes
CIPHER_PAIRWISE=CCMP
CIPHER_GROUP=CCMP
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=shared
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no

  1. 创建 keys-wlan0 文件

    WPA_PSK=12345678

  2. 配置DHCP服务器 ```bash

    1. vim /etc/dhcp/dhcpd.conf (编辑文档，添加以下内容，按自己定义的网关进行配置)

subnet 192.168.138.0 netmask 255.255.255.0 { range 192.168.138.100 192.168.138.250; option domain-name-servers 192.168.138.1, 223.5.5.5; option domain-name “alidns.com”; option routers 192.168.138.1; option broadcast-address 192.168.138.255; default-lease-time 600; max-lease-time 7200; }

2. 拷贝一份 dhcpd.service 配置文件

cp /usr/lib/systemd/system/dhcpd.service /etc/systemd/system/

3. 编辑文件内容为如下：

[Unit] Description=DHCPv4 Server Daemon Documentation=man:dhcpd(8) man:dhcpd.conf(5) Wants=network-online.target After=network-online.target After=time-sync.target

[Service] Type=notify EnvironmentFile=-/etc/sysconfig/dhcpd ExecStart=/usr/sbin/dhcpd -f -cf /etc/dhcp/dhcpd.conf -user dhcpd -group dhcpd —no-pid bridge2 StandardError=null SuccessExitStatus=143 TimeoutSec=10 Restart=on-failure RestartSec=5

[Install] WantedBy=multi-user.target


8.  启动dhcp服务
```bash
# 设置开机自启
systemctl enable dhcpd
# 启动 dhcp
systemctl start dhcpd 
# 启用伪装IP
firewall-cmd --add-masquerade --permanent
