thank you for reply， i know you means.
but how do you konw one issue is a bug or is a stupid question，or is a advice for the next deploy version？

This is my big effect.

starting failed cause by:

ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

this problem and ip configuration does not matter.
so, i deal with the problem by these steps:

• add config to /etc/security/limits.conf
  @elsearch soft nofile 65536
  @elsearch hard nofile 65536
  @elsearch soft nproc 2048
  @elsearch hard nproc 2048
  @elsearch soft memlock unlimited
  @elsearch hard memlock unlimited
• sysctl max_map_count
  sysctl -w vm.max_map_count=262144
• config elasticsearch.yml
