CentOS8 已废弃network.service，网卡操作需要使用nmcli ，当前整理配置文件操作及相关命令

命令：nmcli

配置文件：/etc/sysconfig/network-scripts/ifcfg-eth0

配置单个ipv4地址IP:60.247.159.221 掩码：255.255.255.0 网关：60.247.159.1

[root@ebs-113436 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0# 申明网卡eth0DEVICE=eth0BOOTPROTO=staticIPADDR=60.247.159.221NETMASK=255.255.255.0GATEWAY=60.247.159.1TYPE=EthernetONBOOT=yes

[root@ebs-113436 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0# 申明网卡eth0DEVICE=eth0BOOTPROTO=staticTYPE=EthernetONBOOT=yesIPADDR0=60.247.159.221IPADDR1=60.247.159.152NETMASK0=255.255.255.0NETMASK1=255.255.255.0......GATEWAY0=60.247.159.1

几个依此添加即可，如果ip较多，一个IP段添加。

先通过 计算ip地址

获取到第一个和最后一个可用ip尾数为193和254，以及掩码255.255.255.192，并注意服务器上网络连接名称，加入

for I in $(seq 193 254); do nmcli con mod eth0 +ipv4.addresses 192.168.1.${I}/26; done

ipv6 批量配置教程

以上配置后需要重启网卡生效；
