自用的VPS快速初始化脚本

• 此脚本仅在 Debian 测试过。
• 需要 root 权限。

重装系统

apt update
apt install -y curl
curl -fsSL https://raw.githubusercontent.com/bin456789/reinstall/main/reinstall.sh -o reinstall.sh
# bash reinstall.sh 系统名称 --ssh-key "你的 SSH 公钥"
bash reinstall.sh debian --ssh-key "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIFnzo2Pgfh1Ko7Ssvk+XvDEUJ78d3cLiY9DQ3NG29cWk senzyosama@gmail.com" --ssh-port 40022
reboot

快速开始

bash <(curl -fsSL https://raw.githubusercontent.com/senzyo/vps-init/refs/heads/main/initialize.sh)

验证配置

cat /etc/vim/vimrc

cat /etc/bash.bashrc

cat /etc/ssh/sshd_config
systemctl status sshd

cat /etc/nftables.conf
systemctl status nftables
nft list ruleset

sysctl net.ipv4.tcp_congestion_control
sysctl net.core.default_qdisc

systemctl status systemd-timesyncd
timedatectl status
timedatectl show-timesync --all
timedatectl timesync-status

更改主机名

hostnamectl set-hostname VPS

重新登录即可看到主机名已更改。

sudo 时可能会报错主机名错误, 对于 Debian, 调整 /etc/hosts, 增加一行 127.0.1.1 VPS:

127.0.0.1       localhost
127.0.1.1       VPS
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters
