this issue resolved. not incompatible issue or bug.
please read message from our developer to your host: "The problem is that mysql speed has been throttled by CloudLinux to a very slow speed. the install script takes very long time to finish DB creation operations. The connection timeout is set to 120 seconds and times out during installation. have increase it to 320, installation finished successfully. "
I think the main lesson is: don't use CloudLinux to throttle mysql too much, otherwise maybe a nightmare for the whole server and all of the websites on it.
