SSH 远程访问

把密钥从本机（windows）拷贝到远程机

cat ~/.ssh/id_rsa.pub | ssh dev@192.168.1.113 "cat >> ~/.ssh/authorized_keys"

Linux 或 MacOS用户直接使用 ssh-copy-id ：

ssh-copy-id -i ~/.ssh/id_rsa.pub dev@192.168.1.113

root 远程访问

Debian系默认禁止以root用户的身份通过ssh远程访问，我们自然不需要考虑这种安全问题。

sudo vim /etc/ssh/sshd_config

将PermitRootLogin注释去掉，改为yes

PermitRootLogin yes

systemctl restart ssh

取消合盖休眠

笔记本会合盖睡眠，为了能够长期稳定运行，关闭合盖睡眠功能。
配置盖子电源设置：

1. 打开/etc/systemd/logind.conf文件进行编辑。

2. 将该行更改为以下所需的设置之一：

   • HandleLidSwitch=poweroff 关闭盖子时关闭计算机
   • HandleLidSwitch=hibernate 在合上盖子时到休眠计算机
   • HandleLidSwitch=suspend 关闭盖子时暂停计算机
   • HandleLidSwitch=ignore 不执行任何操作

     HandleLidSwitch=ignore

3. 保存文件，然后重新启动服务应用更改

   systemctl restart systemd-logind

   Not Recommend

   下面这种方式会导致服务器自动在 /var/log/auth.log 写入大量日志，塞满空间，禁止使用🙅‍

   sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.targethibernate.target hybrid-sleep.target

   禁用Nvidia显卡

   sudo vim /etc/default/grub

   在GRUB_CMDLINE_LINUX_DEFAULT最后添加nouveau.modeset=0
