服务器配置密钥登录并禁止密码登录一键脚本

By admin January 12, 2024 Linux, Tech No Comments

如果你有很多服务器，那么配置公钥是一件很枯燥的事情，于是，一键配置脚本应运而生。 ❗ 请注意，PUB_KEY 可以手动填写或者从你的 github 中下载，亦或者是从某个网站下载。 ❗ 请注意，务必先思考是要增加还是覆盖公钥，然后择一运行，否则你的公钥可能丢失。下方代码可以直接粘贴在 Linux Bash 中运行，但是，请将公钥链接替换为自己的 Github 地址或者其他【可访问】的 URL！！

#!/usr/bin/env bash
PUB_KEY=$(curl -fsSL https://github.com/someone.keys)
if [ ! -f &quot;${HOME}/.ssh/authorized_keys&quot; ]; then
mkdir -p ${HOME}/.ssh/
touch ${HOME}/.ssh/authorized_keys
fi
# 追加
echo -e &quot;\n${PUB_KEY}\n&quot; &gt;&gt; ${HOME}/.ssh/authorized_keys
# 覆盖
echo -e &quot;${PUB_KEY}\n&quot; &gt; ${HOME}/.ssh/authorized_keys
chmod 700 ${HOME}/.ssh/
chmod 600 ${HOME}/.ssh/authorized_keys
sudo sed -i &quot;s@.*\(PasswordAuthentication \).*@\1no@&quot; /etc/ssh/sshd_config
sudo sed -i &#039;s/#\?PubkeyAuthentication \(yes\|no\)/PubkeyAuthentication yes/&#039; /etc/ssh/sshd_config
sudo sed -i &#039;s/^#AuthorizedKeysFile/AuthorizedKeysFile/&#039; /etc/ssh/sshd_config
sudo systemctl restart sshd

#!/usr/bin/env bash

PUB_KEY=$(curl -fsSL https://github.com/someone.keys)

if [ ! -f "${HOME}/.ssh/authorized_keys" ]; then

mkdir -p ${HOME}/.ssh/

touch ${HOME}/.ssh/authorized_keys

# 追加

echo -e "\n${PUB_KEY}\n" >> ${HOME}/.ssh/authorized_keys

# 覆盖

echo -e "${PUB_KEY}\n" > ${HOME}/.ssh/authorized_keys

chmod 700 ${HOME}/.ssh/

chmod 600 ${HOME}/.ssh/authorized_keys

sudo sed -i "s@.*$PasswordAuthentication $.*@\1no@" /etc/ssh/sshd_config

sudo sed -i 's/#\?PubkeyAuthentication $yes\|no$/PubkeyAuthentication yes/' /etc/ssh/sshd_config

sudo sed -i 's/^#AuthorizedKeysFile/AuthorizedKeysFile/' /etc/ssh/sshd_config

sudo systemctl restart sshd

云服务器修改默认 root 登录

By admin January 12, 2024 Linux, Tech No Comments

一些云厂商，例如 AWS 和 Azure，默认禁止 Root 登录，需要 admin 登陆后，再执行 sudo su root 来提权，以保障安全。运行如下脚本即可一键解决此类问题。

sudo su root
cd
sudo sed -i &#039;s/^.*PermitRootLogin.*/PermitRootLogin yes/g&#039; /etc/ssh/sshd_config;
sudo sed -i &#039;s/^.*PasswordAuthentication.*/PasswordAuthentication yes/g&#039; /etc/ssh/sshd_config;
sudo service sshd restart
sed -i &#039;s/.*\(ssh-ed25519 .*\)/\1/&#039; ~/.ssh/authorized_keys
# 你也有可能用的是ssh-rsa，那么就把上面的ssh-ed25519改成ssh-rsa
# sed -i &#039;s/.*\(ssh-rsa .*\)/\1/&#039; ~/.ssh/authorized_keys

sudo su root

sudo sed -i 's/^.*PermitRootLogin.*/PermitRootLogin yes/g' /etc/ssh/sshd_config;

sudo sed -i 's/^.*PasswordAuthentication.*/PasswordAuthentication yes/g' /etc/ssh/sshd_config;

sudo service sshd restart

sed -i 's/.*$ssh-ed25519 .*$/\1/' ~/.ssh/authorized_keys

# 你也有可能用的是ssh-rsa，那么就把上面的ssh-ed25519改成ssh-rsa

# sed -i 's/.*$ssh-rsa .*$/\1/' ~/.ssh/authorized_keys

Linux上使用Duplicati进行备份

By admin July 17, 2022 Linux, Tech No Comments

Duplicati安装从https://www.duplicati.com/download下载最新版本该软件需要几个库才能工作，主要是单声道库。安装软件最简单的方法是让它通过dpkg安装失败，然后使用apt-get安装缺少的软件包： sudo dpkg -i duplicati_2.0.6.3-1_all.deb sudo apt-get –fix-broken install 请注意，安装程序包在第一个实例上失败，然后我们使用apt来安装依赖项。启动守护进程： sudo systemctl start duplicati.service 如果您希望在操作系统使用时自动启动： sudo systemctl enable duplicati.service 要检查服务正在运行： netstat -ltn | grep 8200

Watchtower – 自动更新 Docker 镜像与容器

By admin June 26, 2022 Docker, Linux, Tech No Comments

快速启动执行以下标准命令启动 Watchtower 容器,并每 5 分钟一次检查所有容器的镜像是否为最新版,如发现镜像更新将会自动停止容器,删除容器,拉取最新镜像,在以之前启动容器的命令启动容器. docker run -d \ –name watchtower \ -v /var/run/docker.sock:/var/run/docker.sock \ containrrr/watchtower 清理旧镜像镜像在更新后旧镜像标签会变为none,长期自动更新会导致过多的none镜像占用空间,加入–cleanup参数可以在每次更新后自动删除none镜像. docker run -d \ –name watchtower \ –restart always \ -v…
