SSH免密登录是一种通过SSH协议实现的无需输入密码即可登录目标主机的方式。它可以提高用户的登录效率和安全性。
#!/bin/bash
# 生成公钥和私钥
ssh-keygen
# 将公钥复制到目标主机上
read -p "请输入目标主机的IP地址或域名：" host
read -p "请输入目标主机的用户名：" user
ssh-copy-id -i ~/.ssh/id_rsa.pub $user@$host
# 配置目标主机的ssh服务
echo "RSAAuthentication yes" >> /etc/ssh/sshd_config
echo "PubkeyAuthentication yes" >> /etc/ssh/sshd_config
echo "AuthorizedKeysFile .ssh/authorized_keys" >> /etc/ssh/sshd_config
systemctl restart sshd
# 将私钥添加到SSH代理中
ssh-add ~/.ssh/id_rsa
echo "SSH免密登录配置完成！"
