| - | ===== Setup DHCP Service ===== | ||
| - | Install DHCP server: | ||
| - | <code bash> | ||
| - | yum install dhcp | ||
| - | </code> | ||
| - | 修改IPv6 dhcp設定(/etc/dhcp/dhcpd6.conf)，加入以下內容: | ||
| - | <code bash> | ||
| - | default-lease-time 2592000; | ||
| - | preferred-lifetime 604800; | ||
| - | option dhcp-renewal-time 3600; | ||
| - | option dhcp-rebinding-time 7200; | ||
| - | allow leasequery; | ||
| - | option dhcp6.info-refresh-time 21600; | ||
| - | dhcpv6-lease-file-name "/var/lib/dhcpd/dhcpd6.leases"; | ||
| - | subnet6 fc00::/7 { | ||
| - | range6 fc00:0:0:0:0:0:0:10 fc00:0:0:0:0:0:0:1000; | ||
| - | } | ||
| - | </code> | ||
| - | 重新啟動services: | ||
| - | <code bash> | ||
| - | systemctl restart dhcpd6.service | ||
| - | </code> | ||
| - | 如果啟動有發生問題，請下systemctl status dhcpd6.service去看錯誤原因。 | ||
