Ubuntu 新裝配置

Ubuntu 新裝配置

一、配置apt源

1、備份ubuntu

• mv /etc/apt/sources.list /etc/apt/sources.list.bak

2、配置清華源

• su root
  cat > /etc/apt/sources.list <<EOF
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
  deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
  deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
  deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
  deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
  deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
  EOF

3、更新源

• sudo apt-get update
  sudo apt-get upgrade -y

二、安裝必要的軟件

sudo apt-get install curl wget vim ssh -y

三、配置ssh

1、開啟root遠程登陸

vim /etc/ssh/sshd_config
PermitRootLogin yes #取消注釋

2、重啟ssh服務

systemctl enable ssh
systemctl start ssh

四、關閉ubuntu ssh連接時的歡迎信息

1、關閉這個主要是為了防止泄露一些系統信息

sudo sed -i '/pam_motd.so/ s/^/#/g' /etc/pam.d/sshd 

#就是為了注釋下面兩行，不讓他們在現實開機信息
#session    optional     pam_motd.so  motd=/run/motd.dynamic
#session    optional     pam_motd.so noupdate

五、配置終端顏色

vim ~/.bashrc
export PS1="\[\033[01;31m\]\u\[\033[00m\]@\[\033[01;32m\]\h\[\033[00m\][\[\033[01;33m\]\t\[\033[00m\]]:\[\033[01;34m\]\w\[\033[00m\]\n$ "

#生效
source ~/.bashrc
