CentOS8 Stream 網(wǎng)卡配置操作
- 威海服務(wù)器/VPS 威海CentOS
- 2415
CentOS8 已廢棄network.service，網(wǎng)卡操作需要使用nmcli ，當(dāng)前整理配置文件操作及相關(guān)命令
命令：nmcli
配置文件：/etc/sysconfig/network-scripts/ifcfg-eth0
配置單個(gè)ipv4地址
IP:60.247.159.221 掩碼：255.255.255.0 網(wǎng)關(guān)：60.247.159.1
[root@ebs-113436 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
# 申明網(wǎng)卡eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=60.247.159.221
NETMASK=255.255.255.0
GATEWAY=60.247.159.1
TYPE=Ethernet
ONBOOT=yes
配置多個(gè)ipv4地址
IP1:60.247.159.221 掩碼1：255.255.255.0 網(wǎng)關(guān)1：60.247.159.152
IP2:60.247.159.221 掩碼2：255.255.255.0
多ip配置一般只需要配置一個(gè)GATEWAY0 網(wǎng)關(guān)即可
[root@ebs-113436 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
# 申明網(wǎng)卡eth0
DEVICE=eth0
BOOTPROTO=static
TYPE=Ethernet
ONBOOT=yes
IPADDR0=60.247.159.221
IPADDR1=60.247.159.152
NETMASK0=255.255.255.0
NETMASK1=255.255.255.0
.
.
.
.
.
.
GATEWAY0=60.247.159.1
幾個(gè)依此添加即可，如果ip較多，一個(gè)IP段添加。
先通過(guò)http://tool.520101.com/wangluo/ipjisuan/ 計(jì)算ip地址

獲取到第一個(gè)和最后一個(gè)可用ip尾數(shù)為193和254，以及掩碼255.255.255.192，并注意服務(wù)器上網(wǎng)絡(luò)連接名稱，加入
for I in $(seq 193 254); do nmcli con mod eth0 +ipv4.addresses 192.168.1.${I}/26; done
單個(gè)ipv6配置

以上配置后需要重啟網(wǎng)卡生效；
網(wǎng)卡服務(wù)重啟
# 查看網(wǎng)卡名稱
[root@ebs-113436 ~]# nmcli c
NAME UUID TYPE DEVICE
System eth0 5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03 ethernet eth0
System eth1 9c92fad9-6ecb-3e6c-eb4d-8a47c6f50c04 ethernet eth1
# 重啟網(wǎng)卡服務(wù)
[root@ebs-113436 ~]# nmcli c reload "System eth0" / nmcli c up "System eth0"
# 如果不生效
[root@ebs-113436 ~]# nmcli device reapply eth0
[root@ebs-113436 ~]# nmcli device connect eth0
