2.3. 自动安装安全更新

步骤

1. 在 /etc/dnf/automatic.conf 文件中，在 [commands] 部分，确保将 upgrade_type 选项被设置为 default 或 security ：

   [commands]
   #  What kind of upgrade to perform:
   # default                            = all available upgrades
   # security                           = only the security upgrades
   upgrade_type = security

2. 启用并启动 systemd 计时器单元：

   # systemctl enable --now dnf-automatic-install.timer

验证

1. 验证计时器是否已启用：

   # systemctl status dnf-automatic-install.timer
