1.配置網卡ip
1)配置網卡eth0,本地內網網卡無需指定網關和域名服務器
root@ubuntu1804:~# vim /etc/netplan/01-netcfg.yaml network: version: 2 renderer: networkd ethernets: eth0: dhcp4: no addresses: [192.168.1.30/24]
2)配置網卡eth1,要保持嚴格縮進,否則會導致網卡起不來
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]
2.修改網卡名為eth*
1)編輯grub文件
root@ubuntu1804:~#vim /etc/default/grub …… GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0" ……
2)加載更新grub文件
root@ubuntu1804:~#update-grub
3)重啟機器實現網卡名更改
root@ubuntu1804:~#reboot
4)啟動機器實現網卡名的修改
若要再次修改網卡ip,修改完后需重啟網絡
root@ubuntu1804:~#netplan apply #重啟網卡命令
3.配置為國內阿里雲倉庫源
1)配置ubuntu倉庫源
root@ubuntu1804:~# vim /etc/apt/sources.list deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
2)更新倉庫
root@ubuntu1804:~# apt update Get:1 http://mirrors.aliyun.com/ubuntu bionic InRelease [242 kB] Get:2 http://mirrors.aliyun.com/ubuntu bionic-security InRelease [88.7 kB] Get:3 http://mirrors.aliyun.com/ubuntu bionic-updates InRelease [88.7 kB] Get:4 http://mirrors.aliyun.com/ubuntu bionic-proposed InRelease [242 kB] ……
3)升級本機所有已安裝的軟件包
root@ubuntu1804:~# apt upgrade
4.安裝初始化常用的軟件包
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件包
[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
5.開啟遠程連接並允許root賬戶直接登錄
1)編輯ssh遠程服務配置文件,注釋掉禁止root秘鑰登錄
root@ubuntu1804:~# vim /etc/ssh/sshd_config
2)再重新啟動sshd服務,即可實現直接以root身份登錄虛擬機或root遠程登錄
root@ubuntu1804:~# systemctl restart sshd
