香港VPS的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
配置多个ipv4地址
-
IP1:60.247.159.221 掩码1:255.255.255.0 网关1:60.247.159.152
-
IP2:60.247.159.221 掩码2:255.255.255.0
多ip配置一般只需要配置一个GATEWAY0 网关即可
-
[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http://tool.520101.com/wangluo/ipjisuan/ 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

以上配置后需要重启网卡生效;
网卡服务重启
