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、開啓root遠程登陸
vim /etc/ssh/sshd_config
PermitRootLogin yes #取消註釋2、重啓ssh服務
systemctl enable ssh
systemctl start ssh四、關閉ubuntu ssh連接時的歡迎信息
1、關閉這個主要是爲了防止泄露一些系統信息
sudo sed -i '/pam_motd.so/ s/^/#/g' /etc/pam.d/sshd
#就是爲了註釋下面兩行，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
