香港VPS CentOS8 Stream 网卡配置操作

云服务器 2026-01-21 15:06 45

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

forIin$(seq193254);donmcliconmodeth0+ipv4.addresses192.168.1.${I}/26;done

单个ipv6配置ipv4：60.247.159.221掩码：255.255.255.0网关：60.247.159.1

ipv6：240E:D9:C200:160:9404::1A80掩码位数：64网关：240e:d9:c200:160::1

ipv6：240E:D9:C200:160:9404::1A80-240E:D9:C200:160:9404::1a9f掩码位数：64网关：240e:d9:c200:160::1

以上配置后需要重启网卡生效；
