實驗-禁用網(wǎng)卡命名規(guī)則:

在GRUB_CMDLINE_Linux=“rd.lvm.lv=rhel/root? vconsole.keymap=us vconsole.font=latarcyheb-sunl6 crashkernel=auto rhgb quiet net.ifnames=0 bios sdevname=0"行尾的引號內(nèi)部加入 net.ifnames=0 biosdevname=0 參數(shù)

grub2-mkconfig - o /boot/grub2/grub.cfg

重啟后系統(tǒng)將不采用網(wǎng)卡命名規(guī)則而是采用原RHEL6的命名規(guī)則

實驗臨時修改IP:

ifconfig eno16777736 100.100.100.100/16

ifconfig?

nmcli connection down eno16777736;nmcli connection up eno16777736

ifconfig

實驗-修改網(wǎng)絡(luò)參數(shù)官方推薦版：

nmcli connection modify eno167..?? ipv4.method manual ipv4.addresses "192.168.100.1/24 192.168.100.1"? ipv4.dns 192.168.100.1 connection.autoconnect yes

nmcli connection modify eno167..?? +ipv4.addresses 10.0.0.1/8

nmcli connection down eno1677..? ;nmcli connection up? eno1677..

實驗添加IPV6的地址：

nmcli connection modify eno167..?? ipv6.method manual ipv6.addresses? '2001：：1/64? 2001::1 '? ipv6.dns 2001：：1

nmcli connection down eno1677..? ;nmcli connection up? eno1677..

ping6 2001::1

實驗-多配置文件管理網(wǎng)卡：

nmcli connection add type ethernet con-name home ifname eno 1677..

nmcli connection? modify home ipv4.method manual ipv4.addresses "10.0.0.1/24 10.0.0.1" ipv4.dns 10.0.0.1

nmcli connection down eno1677..

nmcli connection?? up?? home

查看地址已經(jīng)更改

實驗-單配置文件增加：：信息

vim /etc/sysconfig/network-scripts/ifcfg-eno16...

IPADDR1=10.0.0.1

PREFIX1=8

GATEWAY1=10.0.0.1

DNS2=10.0.0.1

systemctl restart NetworkManager

ip addr show

實驗-新增網(wǎng)卡

新添加一塊網(wǎng)卡

nmcli device show 可以發(fā)現(xiàn)新增了一塊網(wǎng)卡

nmcli connection add type ethernet en0.... ifname eno....

nmcli connection modify en0.... ipv4.method manual ipv4.addresses "192.168.100.1/24 192.168.100.1" ipv4.dns 192.168.100.1 connection.autoconnect yes

systemctl restart NetworkManager

ifconfig
