如果设置 huge_pages = on ，除非您在操作系统上定义了足够多的大页面，否则服务器不会启动。见 the documentation :

huge_pages (enum)

Controls whether huge pages are requested for the main shared memory area. Valid values are try (the default), on, and off. With huge_pages set to try, the server will try to request huge pages, but fall back to the default if that fails. With on, failure to request huge pages will prevent the server from starting up. With off, huge pages will not be requested.
