Can't run uWebSockets on CentOS 7 with glibc-2.17

Error: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /root/workspace/backend/node_modules/uWebSockets.js/uws_linux_x64_72.node)

Latest glibc version for CentOS 7 is 2.17.
I know that latest version for CentOS 8 is 2.30 but I can’t upgrade, because my VDS depends on host’s machine kernel (which is very old).

Is there any way to run/compile it with glibc-2.17 or update glibc?

EDIT:
My kernel version is 2.6.32-042stab141.3.

I can build it and install to /opt/glibc-2.18 without errors, but when I trying to use this I see Segmentation fault error.

P.S. I builded it successfully on Fedora 23 with same OpenVZ kernel.

    Yes: just do it (download source, build on your target machine, profit).

    or update glibc?

    You didn’t say what your “very old kernel” is, but if GLIBC-2.18 supports it, then yes, you can update GLIBC.

    However, any mistake you make in the process may make your system un-bootable. See this answer.

    I have built a custom binary (and tutorial) that will solve your exact problem.
