Answer :
$ oerr ora 27137
27137, 00000, "unable to allocate large pages to create a shared memory segment"
// *Cause: Parameter USE_LARGE_PAGES set to only, but large pages were not
// configured properly
// *Action: Check alert file for more information
Your output shows hugepages were not configured, but the database is configured to use only large pages (use_large_pages=only), hence it can not start.
Configure the required amount of pages by setting the vm.nr_hugepages in /etc/sysctl.conf, the appropriate memlock limit in /etc/security/limits.conf, then reboot and start the database.
Configuring HugePages on Linux
If you do not need hugepages, simply edit the parameter file of the database, and unset the use_large_pages parameter.
