ubuntu如何修改IP地址和apt源

Posted 2022-01-03

新安装的ubuntu没有vim，使用vi修改自己的IP地址

[email protected]:~# cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto ens3
iface ens3 inet static
address 192.168.200.7
netmask 255.255.255.0
gateway 192.168.200.1
dns-nameserver 192.168.200.200

ubuntu系统如何修改apt源，使用aliyun源为例：
将旧版本内容做好备份。

[email protected]:~# cp /etc/apt/sources.list /etc/apt/sources.list_bak

添加以下内容

[email protected]:~# cat /etc/apt/sources.list
deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse

更新自己的源，即可

[email protected]:~# apt update
[email protected]:~# apt-get update

接下来验证源是否正常使用：

[email protected]:~# apt install -y openssh-server vim net-tools lrzsz
