WARNING: You are trying to use the MEMORY_TARGET feature. This feature requires the /dev/shm file system to be mounted for at least 1140850688 bytes. /dev/shm is either not mounted or is mounted with available space less than this size. Please fix this so that MEMORY_TARGET can work as expected. Current available is 956751872 and used is 0 bytes. Ensure that the mount point is /dev/shm for this directory.

看样子是shm太小

--调整shm
