ubuntu 18.04：

1）配置網絡卡eth0，本地內網網絡卡無需指定閘道器和網域名稱伺服器

root@ubuntu1804:~# vim /etc/netplan/01-netcfg.yaml


network:


version: 2


renderer: networkd


ethernets:


eth0:


dhcp4: no


addresses: [192.168.1.30/24]
2）配置網絡卡eth1，要保持嚴格縮排，否則會導致網絡卡起不來
root@ubuntu1804:~# vim /etc/netplan/02-netcfg.yaml 


network:


version: 2


renderer: networkd


ethernets:


eth1:


dhcp4: yes


addresses: [192.168.10.107/24]


gateway4: 192.168.10.1


nameservers:


addresses: [223.6.6.6]
1）編輯grub檔案
root@ubuntu1804:~#vim /etc/default/grub


……grub_cmdline_linux="net.ifnames=0 biosdevname=0"


……
2）載入更新grub檔案
root@ubuntu1804:~#update-grub
3）重啟機器實現網絡卡名更改
root@ubuntu1804:~#reboot
4）啟動機器實現網絡卡名的修改1）配置ubuntu倉庫源
root@ubuntu1804:~# vim /etc/apt/sources.list


deb bionic main restricted universe multiverse


deb-src bionic main restricted universe multiverse


deb bionic-security main restricted universe multiverse


deb-src bionic-security main restricted universe multiverse


deb bionic-updates main restricted universe multiverse


deb-src bionic-updates main restricted universe multiverse


deb bionic-proposed main restricted universe multiverse


deb-src bionic-proposed main restricted universe multiverse


deb bionic-backports main restricted universe multiverse


deb-src bionic-backports main restricted universe multiverse
2）更新倉庫
root@ubuntu1804:~# apt update


get:1 bionic inrelease [242 kb]


get:2 bionic-security inrelease [88.7 kb] 


get:3 bionic-updates inrelease [88.7 kb] 


get:4 bionic-proposed inrelease [242 kb] 


……
3）公升級本機所有已安裝的軟體包
root@ubuntu1804:~# apt upgrade
1)在ubuntu18.04中常用的初始化安裝包
root@ubuntu1804:~# apt-get install iproute2  ntpdate  tcpdump telnet traceroute nfs-kernel-server nfs-common  lrzsz tree  openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev gcc openssh-server iotop unzip zip ipmitool -y
2）在centos7的初始化最小化安裝常用軟體包
[root@centos7 ~]# yum install  vim iotop bc gcc gcc-c++ glibc glibc-devel pcre pcre-devel openssl  openssl-devel zip unzip zlib-devel  net-tools lrzsz tree ntpdate telnet lsof tcpdump wget libevent libevent-devel bc  systemd-devel bash-completion traceroute -y
1）編輯ssh遠端服務配置檔案，注釋掉禁止root秘鑰登入
root@ubuntu1804:~# vim /etc/ssh/sshd_config

2）再重新啟動sshd服務，即可實現直接以root身份登入虛擬機器或root遠端登入

root@ubuntu1804:~# systemctl restart sshd
