linux網(wǎng)卡配置

查看網(wǎng)卡所在區(qū)域：
firewall-cmd --get-zone-of-interface=eno16777736

查看服務(wù)是否被允許：
firewall-cmd --zone=public --query-service=http

防火墻添加端口：

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-port=9090/tcp
firewall-cmd --reload

 firewall-cmd --permanent --zone=public --add-port=8080-8081/tcp
irewall-cmd --reload

nmcli con show [active]
nmcli con show "static-eth0"
nmcli dev status
nmcle dev show eth0
apply modification
   systemctl restart network.service
   nmcli con reload

nmcli connection show   查看鏈接信息
nmcli device show   查看設(shè)備信息
nmcli device status  查看設(shè)備狀態(tài)

hostnamectl set-hostname desktop.group8.example.com
nmcli connection show
nmcli con modify eno16777736 ipv4.addresses "172.24.8.10/24 172.24.8.254" ipv4.dns "172.24.8.254"
nmcli con modify eno16777736 connection.autoconnect yes ipv4.method manual
nmcli con up eno16777736
systemctl restart network .service

add additional network ipv4 address
nmcli con add con-name ''yeslab" ifname eth0 type ethernet ip4 172.25.1.11/24 gw4 172.25.1.254   新建連接yeslab 并配置IP地址
nmcli con modify "yeslab" ipv4.dns 172.25.254.254                    配置yeslab連接dns
nmcli con modify "yeslab" ipv4.addresses 172.25.1.18/24        修改yeslab的IP地址
nmcli con modify "yeslab" connection.autoconnect yes            啟用 yeslab的配置
nmcli con modify "system eth0" connection.autoconnect no    關(guān)閉system eth0 d的配置
systemctl restart network .service     重啟網(wǎng)絡(luò)服務(wù)
nmcli con modify "system eth0" +ipv4.addresses 10.1.1.1/24   為system eth0添加 地址 ，可以同時(shí)擁有多個(gè)地址
hostnamectl set-hostname serverX.example.com  配置系統(tǒng)名稱

網(wǎng)絡(luò)綁定
建立team 端口
nmcel con add type team con-name y-team ifname team1 config '{"runner":{"name":"loadbalance"}}'

nmcle con mod y-team ipv4.addresses '192.168.1.100/24' 為team口配置IP地址
nmcli con mod y-team ipv4.method manual 配置地址為固定

綁定從物理端口

nmcli con add type team-slave con-name team1-port1 ifname eth2 master team1
nmcli con add type team-slave con-name team1-port2 ifname eth3 master team1
Systemctl restart network

nmcli con up team1
teamdctl team1 state

nmcli device disconnect eth2 關(guān)閉端口

Configuring software bridge

建立一個(gè)橋接

Nmcli con add type bridge con-name br1 ifname br1
Nmcli con mod br1 ipv4.addresses '192.168.1.100/24
Nmcli con mod br1 ipv4.method manual

Nmcli con add type bridge-slave con-name br1-port1 ifname eth2 master br1
Nmcli con add type bridge-slave con-name br1-port2 ifname eth3 master br1

Ip link
Brctl show 
Ping -1 bri 192.168.1.254  使用橋接端口PING測(cè)試
Ping -c 10 -I br1 192.168.1.254

Ipv6配置

nmcli connection add con-name y-6 ifname eth0 type ethernet ip6 2016:abcd::2/64
Nmcli connettionh modify y-6 ipv6.mdthod manual
Nmcli connection mokify y-6connection.autoconnect yes
nmcli con modify "system eth0" connection.autoconnect no
Systemctl restart network
Nmcli device show
