7.12. 禁用 kpatch.service

流程

1. 验证 kpatch.service 是否已启用。

   # systemctl is-enabled kpatch.service
   enabled

2. 禁用 kpatch.service ：

   # systemctl disable kpatch.service
   Removed /etc/systemd/system/multi-user.target.wants/kpatch.service.

   • 请注意，应用的内核补丁模块仍然被载入：

     # kpatch list
     Loaded patch modules:
     kpatch_5_14_0_1_0_1 [enabled]
     
     Installed patch modules:
     kpatch_5_14_0_1_0_1 (5.14.0-1.el9.x86_64)

3. 重启您的系统。

4. 可选：验证 kpatch.service 的状态。

   # systemctl status kpatch.service
   ● kpatch.service - "Apply kpatch kernel patches"
      Loaded: loaded (/usr/lib/systemd/system/kpatch.service; disabled; vendor preset: disabled)
      Active: inactive (dead)

   示例输出测试 kpatch.service 已被禁用且没有在运行。因此，内核实时修补解决方案不活跃。

5. 验证内核补丁模块是否已卸载。

   # kpatch list
   Loaded patch modules:
   
   Installed patch modules:
   kpatch_5_14_0_1_0_1 (5.14.0-1.el9.x86_64)

   上面的示例输出显示内核补丁模块仍处于安装状态，但没有修补内核。
