Ubuntu最小化安装 （1804版）

一、Ubuntu最小化安装

1、修改内核参数，修改网卡名称，将ens33改为eth0

root@ubuntu:vim /etc/default/grub
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
root@ubuntu:update-grub

2、修改系统的IP地址

root@node4:~# vim  /etc/netplan/50-cloud-init.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: no
      addresses: [192.168.7.110/24]
      gateway4: 192.168.7.2
      nameservers:
              addresses: [192.168.7.2]

 3、应用ip配置并重启测试： 

root@node4:~# netplan  apply

4、修改apt源仓库/etc/apt/sources.list:1804版本的Ubuntu，参考阿里云仓库：https://developer.aliyun.com/mirror/ubuntu?spm=a2c6h.13651102.0.0.53322f701347Pq

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

5、安装常用命令

# apt-get update  #更新
# apt-get purge ufw lxd lxd-client lxcfs lxc-common #卸载不用的包
# apt-get  install iproute2  ntpdate  tcpdump telnet traceroute nfs-kernel-server nfs-common \
lrzsz tree  openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev ntpdate tcpdump telnet traceroute \
gcc openssh-server lrzsz tree  openssl libssl-dev libpcre3 \
libpcre3-dev zlib1g-dev ntpdate tcpdump telnet traceroute iotop unzip zip

6、重启linux系统，然后做快照即可。　　

# reboot

7、想要root用户登录，先sudo切换到root用户，然后修改ssh服务vim /etc/ssh/sshd_config

root@node4:~# sudo su
root@node4:~# vim /etc/ssh/sshd_config
PermitRootLogin yes  # 允许root用户登录即可
UseDNS no    # 避免对自己ssh进行反向解析

root@node4:~# systemctl restart sshd   # 重启sshd服务就可以root登录
