关于开启 SSH 远程登录的方法

• 验证是否已安装 SSH 服务

  ls /etc | grep ssh
  

  如果没有这个文件夹说明系统未安装 SSH 服务，你需要通过包管理工具安装 openssh 软件包

• 设置允许 Root 用户登录

  cat /etc/ssh/sshd_config | grep -Eq "^[# ]?PermitRootLogin " ; [ $? -eq 0 ] && sed -i 's/^[# ]\?PermitRootLogin.*/PermitRootLogin yes/g' /etc/ssh/sshd_config || echo -e "\nPermitRootLogin yes" >> /etc/ssh/sshd_config
  

• 设置密码认证

  cat /etc/ssh/sshd_config | grep -Eq "^[# ]?PasswordAuthentication " ; [ $? -eq 0 ] && sed -i 's/^[# ]\?PasswordAuthentication.*/PasswordAuthentication yes/g' /etc/ssh/sshd_config || echo -e "\nPasswordAuthentication yes" >> /etc/ssh/sshd_config
  

• 启动/重启 SSH 服务

  ps -ef | grep -q ssh ; [ $? -eq 0 ] && systemctl restart sshd || systemctl enable --now sshd
  

还原已备份的软件源

cp -rvf /etc/apt/sources.list.bak /etc/apt/sources.list
apt-get update

Debian   Ubuntu   Kali   Deepin   Armbian

cp -rvf /etc/yum.repos.d.bak /etc/yum.repos.d
yum makecache

Red Hat Enterprise Linux   CentOS   Rocky Linux   AlmaLinux   Fedora   OpenCloudOS   openEuler

cp -rvf /etc/zypp/repos.d.bak /etc/zypp/repos.d
zypper ref

cp -rvf /etc/pacman.d/mirrorlist.bak /etc/pacman.d/mirrorlist
pacman -Sy

cp -rvf /etc/apk/repositories.bak /etc/apk/repositories
apk update -f

其它

• 如果提示 bash: /proc/self/fd/11: No such file or directory，请切换至 Root 用户执行，切换命令为 sudo -i 或 su root
