通過SSH協(xié)議建立安全連接是登錄服務(wù)器的******方式。在Windows系統(tǒng)中可使用PowerShell或第三方工具(如PuTTY),Linux/macOS用戶可直接使用終端執(zhí)行以下命令:
ssh username@server_ip -p port_number
-p
參數(shù)指定推薦使用RSA密鑰替代密碼登錄以提高安全性,執(zhí)行以下步驟創(chuàng)建密鑰對:
ssh-keygen -t rsa -b 4096
ssh-copy-id user@server_ip
ssh -i ~/.ssh/private_key user@server_ip
完成基礎(chǔ)連接后,建議實施以下安全策略:
修改SSH配置文件/etc/ssh/sshd_config
示例:
Port 22022 PermitRootLogin no PasswordAuthentication no
