OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.重点看 error:
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
Means: the host of the largest virtual memory setting is too small.
