第三天
01 使用vm虛擬機器 安裝centos7系統 然後使用橋接模式 自定義ip 實戰一下 如果很熟練也不用實戰演示
直接把配置ip 用到配置 寫到這裡即可
centos 系統
cd /etc/sysconfig/network-scripts/
ls
vi ifcfg-ens160
NAME=eth0
DEVICE=eth0
BOOTPROTO=dhcp|static|none
IPADDA=10.0.0.7
PREFIX=24
ONBOOT=yes
生效
reboot
或者
nmcli connection reload
nmcli connection 看一下你的網路卡名稱是多少
nmcli connection up eth0
ubuntu
注意：yaml檔案縮排非常嚴格，錯一位都不行，且配置檔案必須以 .yaml字尾
如果有多個ip要配置，也可以寫在一個檔案裡

- 使用xshell 遠端連線伺服器 實戰演示 會的 就不用演示了
