自己配置

HWADDR=08:00:27:98:87:e0  # 对应mac地址
TYPE=Ethernet
BOOTPROTO=static # 设置为使用静态IP地址
IPADDR=192.168.1.116 # 设置静态IP地址
NETMASK=255.255.255.0 # 设置子网掩码。
GATEWAY=192.168.1.1 # 设置网关地址。
DNS1=223.6.6.6 # 设置首选DNS服务器（如果需要的话）
DNS2=223.5.5.5
NAME=enp0s8
UUID=ffcbb7a5-8d59-490a-8205-7c923328d507 # 记得修改
DEVICE=enp0s8
ONBOOT=yes # 设置网卡为开机启动
HOSTNAME=hy-node5  # 设置主机名，本地解析
