windows2019服务器迁移DHCP服务到CentOS7

windows2019服务器迁移DHCP服务到CentOS7



1、powershell导出服务器全部作用域
Get-Dhcpserverv4Scope -computername WIN-D2F3V83UDDG >> Scope-ip.txt

2、powershell 导出服务器全部保留IP
Get-Dhcpserverv4Scope -computername WIN-D2F3V83UDDG  | Get-DhcpServerv4Reservation -computername WIN-D2F3V83UDDG >> Reservation-ip.txt

3、powershell 导出排除的IPv4地址范围
Get- Dhcp Serverv4ExclusionRange >> Exclusion-ip.txt

4、修改配置文件
vi /etc/dhcp/dhcpd.conf
# dhcpd.conf

# option definitions common to all supported networks...
option domain-name "crland.hk";
option domain-name-servers 10.108.50.130;

default-lease-time 86400;
max-lease-time 86400;

# Use this to enble / disable dynamic dns updates globally.
ddns-update-style none;

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;

# This is a very basic subnet declaration.

#CentOS7服务器直连网段
subnet 10.108.50.128 netmask 255.255.255.224 {
}
#网段IP分配测试
subnet 10.108.50.32 netmask 255.255.255.224 {
  range 10.108.50.34 10.108.50.62;
  option routers 10.108.50.33;
}

# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.

#分配静态IP测试
host test {
  hardware ethernet C8:5B:76:A7:4D:9F;
  fixed-address 10.108.51.44;
}

5、重启CentOS7 DHCP服务
systemctl restart dhcpd.service

6、查看CentOS7 DHCP状态
systemctl status dhcpd.service
