passwd修改默认密码，防止被爆破

echo root:密码 |sudo chpasswd root
apt-get update && apt-get upgrade -y

安装必要软件依赖

apt update -y && apt install -y curl && apt install -y wget && apt install -y git && apt install sudo -y
apt install ffmpeg default-jdk git wget nano vim htop locate p7zip p7zip-full unzip

BBR开启（提速必备）

echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p
sysctl -n net.ipv4.tcp_congestion_control
lsmod | grep bbr
