Debian 新系统五个细节优化

1.更新系统环境以及修改默认密码

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

2.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

3.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

4.安装swap(系统自带可忽略)

bash <(wget -qO- https://fool.im/swap.sh)
